 # 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.
 
+* [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.
 
-* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containerswhich could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
+* [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.

 * [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.

Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-define infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
+* [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)

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.
+
+## 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.

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

 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 has a rich rule set of security rules specifically built for Kubernetes, Linux, and cloud-native.
+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.

+## What can Falco detect?
 
 Falco can detect and alert on any behavior that involves making Linux system calls.
 Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process.
@@ -67,41 +80,99 @@ For example, Falco can easily detect incidents including but not limited to:
 - A standard system binary, such as `ls`, is making an outbound network connection.
 - A privileged pod is started in a Kubernetes cluster.

+## Plugins
+
+Falco comes with a [plugin framework](https://falco.org/docs/plugins/) that extends it to potentially any cloud detection scenario. Plugins are shared libraries that conform to a documented API and allow for:
+
+- Adding new event sources that can be used in rules;
+- Adding the ability to define new fields and extract information from events.
+
+The Falco Project maintains [various plugins](https://github.com/falcosecurity/plugins) and provides SDKs for plugin development.

 Falco enriches these kernel events with information about containers running on the system.

-    # However, they forgot to push the released makefiles

-    #
-    # This is needed because many distros do not ship the right
-    # version of autoreconf, making virtually impossible to build Falco on them.

+
+# --- [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.

+# Proposal for First Class Structured Exceptions in Falco Rules
+
+## Summary
+
+## Motivation
+
+Almost all Falco Rules have cases where the behavior detected by the
+rule should be allowed. For example, The rule Write Below Binary Dir
+has exceptions for specific programs that are known to write below
+these directories as a part of software installation/management:
+
+```yaml
+- rule: Write below binary dir
+  desc: an attempt to write to any file below a set of binary directories
+  condition: >
+    bin_dir and evt.dir = < and open_write
+    and not package_mgmt_procs
+    and not exe_running_docker_save
+    and not python_running_get_pip
+    and not python_running_ms_oms
+    and not user_known_write_below_binary_dir_activities
+...
+```
+In most cases, these exceptions are expressed as concatenations to the original rule's condition. For example, looking at the macro package_mgmt_procs:
+
+```yaml
+- macro: package_mgmt_procs
+  condition: proc.name in (package_mgmt_binaries)
+```
+
+The result is appending `and not proc.name in (package_mgmt_binaries)` to the condition of the rule.
+
+A more extreme case of this is the write_below_etc macro used by Write below etc rule. It has tens of exceptions:
+
+```
+...
+    and not sed_temporary_file
+    and not exe_running_docker_save
+    and not ansible_running_python
+    and not python_running_denyhosts
+    and not fluentd_writing_conf_files
+    and not user_known_write_etc_conditions
+    and not run_by_centrify
+    and not run_by_adclient
+    and not qualys_writing_conf_files
+    and not git_writing_nssdb
+...
+```
+
+The exceptions all generally follow the same structure--naming a program and a directory prefix below /etc where that program is allowed to write files.
+
+### Using Appends/Overwrites to Customize Rules
+
+An important way to customize rules and macros is to use `append: true` to add to them, or `append: false` to define a new rule/macro, overwriting the original rule/macro. Here's an example from Update Package Repository:
+
+```yaml
+- list: package_mgmt_binaries
+  items: [rpm_binaries, deb_binaries, update-alternat, gem, pip, pip3, sane-utils.post, alternatives, chef-client, apk, snapd]
+
+- macro: package_mgmt_procs
+  condition: proc.name in (package_mgmt_binaries)
+
+- macro: user_known_update_package_registry
+  condition: (never_true)
+
+- rule: Update Package Repository
+  desc: Detect package repositories get updated
+  condition: >
+    ((open_write and access_repositories) or (modify and modify_repositories))
+    and not package_mgmt_procs
+    and not exe_running_docker_save
+    and not user_known_update_package_registry
+```
+
+If someone wanted to add additional exceptions to this rule, they could add the following to the user_rules file:
+
+```yaml
+- list: package_mgmt_binaries
+  items: [puppet]
+  append: true
+
+- macro: package_mgmt_procs
+  condition: and not proc.pname=chef
+  append: true
+
+- macro: user_known_update_package_registry
+  condition: (proc.name in (npm))
+  append: false
+```
+
+This adds an 3 different exceptions:
+* an additional binary to package_mgmt_binaries (because append is true),
+* adds to package_mgmt_procs, adding an exception for programs spawned by chef (because append is true)
+* overrides the macro user_known_update_package_registry to add an exception for npm (because append is false).
+
+### Problems with Appends/Overrides to Define Exceptions
+
+Although the concepts of macros and lists in condition fields, combined with appending to lists/conditions in macros/rules, is very general purpose, it can be unwieldy:
+
+* Appending to conditions can result in incorrect behavior, unless the original condition has its logical operators set up properly with parentheses. For example:
+
+```yaml
+rule: my_rule
+condition: (evt.type=open and (fd.name=/tmp/foo or fd.name=/tmp/bar))
+
+rule: my_rule
+condition: or fd.name=/tmp/baz
+append: true
+```
+
+Results in unintended behavior. It will match any fd related event where the name is /tmp/baz, when the intent was probably to add /tmp/baz as an additional opened file.
+
+* A good convention many rules use is to have a clause "and not user_known_xxxx" built into the condition field. However, it's not in all rules and its use is a bit haphazard.
+
+* Appends and overrides can get confusing if you try to apply them multiple times. For example:
+
+```yaml
+macro: allowed_files
+condition: fd.name=/tmp/foo
+
+...
+
+macro: allowed_files
+condition: and fd.name=/tmp/bar
+append: true
+```
+
+If someone wanted to override the original behavior of allowed_files, they would have to use `append: false` in a third definition of allowed_files, but this would result in losing the append: true override.
+
+## Solution: Exceptions as first class objects
+
+To address some of these problems, we will add the notion of Exceptions as top level objects alongside Rules, Macros, and Lists. A rule that supports exceptions must define a new key `exceptions` in the rule. The exceptions key is a list of identifier plus list of tuples of filtercheck fields. Here's an example:
+
+```yaml
+- rule: Write below binary dir
+  desc: an attempt to write to any file below a set of binary directories
+  condition: >
+    bin_dir and evt.dir = < and open_write
+    and not package_mgmt_procs
+    and not exe_running_docker_save
+    and not python_running_get_pip
+    and not python_running_ms_oms
+    and not user_known_write_below_binary_dir_activities
+  exceptions:
+   - name: proc_writer
+     fields: [proc.name, fd.directory]
+   - name: container_writer
+     fields: [container.image.repository, fd.directory]
+     comps: [=, startswith]
+   - name: proc_filenames
+     fields: [proc.name, fd.name]
+     comps: [=, in]
+   - name: filenames
+     fields: fd.filename
+     comps: in
+```
+
+This rule defines four kinds of exceptions:
+  * proc_writer: uses a combination of proc.name and fd.directory
+  * container_writer: uses a combination of container.image.repository and fd.directory
+  * proc_filenames: uses a combination of process and list of filenames.
+  * filenames: uses a list of filenames
+
+The specific strings "proc_writer"/"container_writer"/"proc_filenames"/"filenames" are arbitrary strings and don't have a special meaning to the rules file parser. They're only used to link together the list of field names with the list of field values that exist in the exception object.
+
+proc_writer does not have any comps property, so the fields are directly compared to values using the = operator. container_writer does have a comps property, so each field will be compared to the corresponding exception items using the corresponding comparison operator.
+
+proc_filenames uses the in comparison operator, so the corresponding values entry should be a list of filenames.
+
+filenames differs from the others in that it names a single field and single comp operator. This changes how the exception condition snippet is constructed (see below).
+
+Notice that exceptions are defined as a part of the rule. This is important because the author of the rule defines what construes a valid exception to the rule. In this case, an exception can consist of a process and file directory (actor and target), but not a process name only (too broad).
+
+Exception values will most commonly be defined in rules with append: true. Here's an example:
+
+```yaml
+- list: apt_files
+  items: [/bin/ls, /bin/rm]
+
+- rule: Write below binary dir
+  exceptions:
+  - name: proc_writer
+    values:
+    - [apk, /usr/lib/alpine]
+    - [npm, /usr/node/bin]
+  - name: container_writer
+    values:
+    - [docker.io/alpine, /usr/libexec/alpine]
+  - name: proc_filenames
+    values:
+    - [apt, apt_files]
+    - [rpm, [/bin/cp, /bin/pwd]]
+  - name: filenames
+    values: [python, go]
+```
+
+A rule exception applies if for a given event, the fields in a rule.exception match all of the values in some exception.item. For example, if a program `apk` writes to a file below `/usr/lib/alpine`, the rule will not trigger, even if the condition is met.
+
+Notice that an item in a values list can be a list. This allows building exceptions with operators like "in", "pmatch", etc. that work on a list of items. The item can also be a name of an existing list. If not present surrounding parentheses will be added.
+
+Finally, note that the structure of the values property differs between the items where fields is a list of fields (proc_writer/container_writer/proc_filenames) and when it is a single field (procs_only). This changes how the condition snippet is constructed.
+
+### Implementation
+
+For exception items where the fields property is a list of field names, each exception can be thought of as an implicit "and not (field1 cmp1 val1 and field2 cmp2 val2 and...)" appended to the rule's condition. For exception items where the fields property is a single field name, the exception can be thought of as an implicit "and not field cmp (val1, val2, ...)". In practice, that's how exceptions will be implemented.
+
+When a rule is parsed, the original condition will be wrapped in an extra layer of parentheses and all exception values will be appended to the condition. For example, using the example above, the resulting condition will be:
+
+```
+(<Write below binary dir condition>) and not (
+    (proc.name = apk and fd.directory = /usr/lib/alpine) or (proc.name = npm and fd.directory = /usr/node/bin) or
+	(container.image.repository = docker.io/alpine and fd.directory startswith /usr/libexec/alpine) or
+	(proc.name=apt and fd.name in (apt_files))) or
+	(fd.filename in (python, go))))
+```
+
+The exceptions are effectively syntactic sugar that allows expressing sets of exceptions in a concise way.
+
+### Advantages
+
+Adding Exception objects as described here has several advantages:
+
+* All rules will implicitly support exceptions. A rule writer doesn't need to define a user_known_xxx macro and add it to the condition.
+* The rule writer has some controls on what defines a valid exception. The rule author knows best what is a good exception, and can define the fields that make up the exception.
+* With this approach, it's much easier to add and manage multiple sets of exceptions from multiple sources. You're just combining lists of tuples of filtercheck field values.
+
+## Backwards compatibility
+
+To take advantage of these new features, users will need to upgrade Falco to a version that supports exception objects and exception keys in rules. For the most part, however, the rules file structure is unchanged.
+
+This approach does not remove the ability to append to exceptions nor the existing use of user_xxx macros to define exceptions to rules. It only provides an additional way to express exceptions. Hopefully, we can migrate existing exceptions to use this approach, but there isn't any plan to make wholesale rules changes as a part of this.
+
+This approach is for the most part backwards compatible with older Falco releases. To implement exceptions, we'll add a preprocessing element to rule parsing. The main Falco engine is unchanged.
+
+However, there are a few changes we'll have to make to Falco rules file parsing:
+
+* Currently, Falco will reject files containing anything other than rule/macro/list top-level objects. As a result, `exception` objects would be rejected. We'll probably want to make a one-time change to Falco to allow arbitrary top level objects.
+* Similarly, Falco will reject rule objects with exception keys. We'll also probably want to change Falco to allow unknown keys inside rule/macro/list/exception objects.

+# OSS Libraries Contribution Plan
+
+## Summary
+
+Sysdig Inc. intends to donate **libsinsp**, **libscap**, the **kernel module driver** and the **eBPF driver sources** by moving them to the Falco project.
+
+This means that some parts of the [draios/sysdig](https://github.com/draios/sysdig) repository will be moved to a new GitHub repository called [falcosecurity/libs](https://github.com/falcosecurity/libs).
+
+This plan aims to describe and clarify the terms and goals to get the contribution done.
+
+## Motivation
+
+There are two main OSS projects using the libraries and drivers that we are aware of:
+
+- [sysdig](https://github.com/draios/sysdig)  the command line tool
+- [Falco](https:/github.com/falcosecurity/falco), the CNCF project.
+
+Since the Falco project is a heavy user of the libraries, a lot more than the sysdig cli tool, Sysdig (the company) decided to donate the libraries and the driver to the Falco community.
+
+Sysdig (the command line tool) will continue to use the libraries now provided by the Falco community underneath.
+
+This change is win-win for both parties because of the following reasons:
+
+- The Falco community owns the source code of the three most important parts of the software it distributes.
+  - Right now it is "only" an engine on top of the libraries. This **contribution** helps in making the scope of the Falco project broader. Having the majority of the source code under an **open governance** in the same organization gives the Falco project more contribution opportunities, helps it in **evolving independently** and makes the whole Falco community a strong owner of the processes and decision making regarding those crucial parts.
+
+- Given the previous point, Sysdig (the command line tool) will benefit from the now **extended contributors base**
+
+- Sysdig (the company) can now focus on the user experience and user space features
+
+- **Contributions** to the libraries and drivers will be **easier** to spread across the Falco community
+
+- By being donated, with their own **release process**, **release artifacts**, and **documentation**, the libraries can now live on their own and possibly be used directly in other projects by becoming fundamental pieces for their success.
+
+## Goals
+
+There are many sub-projects and each of them interacts in a different way in this contribution.
+
+Let's see the goals per sub-project.
+
+### libsinsp
+
+1. Extract libsinsp from `draios/sysdig/userspace/libsinsp` (keeping the commit history) into [falcosecurity/libs](https://github.com/falcosecurity/libs)

+
+3. Keep the same code, refactorings will need to be done in subsequent PRs and approved separately
+
+4. Adapt the CMake and build files
+
+5. Install [poiana](https://github.com/poiana) and its workflows on it

+# Plugin System
+
+## Summary
+
+This is a proposal to create an infrastructure to extend the functionality of the Falco libraries via plugins.
+
+Plugins will allow users to easily extend the functionality of the libraries and, as a consequence, of Falco and any other tool based on the libraries.
+
+This proposal, in particular, focuses on two types of plugins: source plugins and extractor plugins.
+
+## Motivation
+
+[libscap](https://github.com/falcosecurity/libs/tree/master/userspace/libscap) and [libsinsp](https://github.com/falcosecurity/libs/tree/master/userspace/libsinsp) provide a powerful data capture framework, with a rich set of features that includes:
+
+- data capture
+- trace files management
+- enrichment
+- filtering
+- formatting and screen rendering
+- Lua scripting (chisels)
+
+These features have been designed with one specific input in mind: system calls. However, they are generically adaptable to a broad set of inputs, such as cloud logs.
+
+With this proposal, we want to dramatically extend the scope of what the libraries, Falco and other tools can be applied to. We want to do it in a way that is easy, efficient and empowers anyone in the community to write a plugin.
+
+## Goals
+
+- To design and implement a plugin framework that makes the libraries more modular and extensible
+- To have a framework that is easy to use
+- To support dynamic loading of plugins, so that the libraries can be extended without having to be recompiled and relinked
+- To enable users to write plugins in any language, with a particular focus on Go, C and C++
+- To have an efficient plugin framework so that, performance-wise, writing a plugin is as close as possible as extending the libraries internal source code
+- To make it possible to write plugins for Linux, MacOS and Windows
+
+## Non-Goals
+
+- To implement plugins other than source and extractor: to be approached as separate task
+- To document the plugin framework and interface: to be approached as separate task
+
+## Proposal
+
+### Plugin Common Information
+
+Both source and extractor plugins have the following:
+
+- A required api version, to ensure compatibility with the plugin framework.
+- A name
+- A description
+- A version
+- A contact field for the plugin authors (website, github repo, twitter, etc).
+- Functions to initialize and destroy the plugin internal state.
+
+### Plugin types
+
+Initially, we will implement support for two types of plugins: source plugins and extractor plugins.
+
+#### Source Plugin
+
+A source plugin implements a new sinsp/scap event source. It has the ability to "open" and "close" a session that provides events. It also has the ability to return an event to the plugin framework via a next() method. Events returned by source plugins have an "event source", which describes the information in the event. This is distinct from the plugin name to allow for multiple kinds of plugins to generate the same kind of events. For example, there might be plugins gke-audit-bridge, eks-audit-bridge, ibmcloud-audit-bridge, etc. that all fetch [K8s Audit](https://kubernetes.io/docs/tasks/debug-application-cluster/audit/) information. The plugins would have different names but would have the same event source "k8s_audit".
+
+Source plugins also have the ability to extract information from events based on fields. For example, a field proc.name extracts a process name from a syscall event. The plugin returns a set of supported fields, and there are functions to extract a value given an event and field. The plugin framework can then build filtering expressions/Falco rule conditions based on these fields combined with relational and/or logical operators. For example, given an expression "ct.name=root and ct.region=us-east-1", the plugin framework handles parsing the expression, calling the plugin to extract values for a given event, and determining the result of the expression. In a Falco output string like "An EC2 Node was created (name=%ec2.name region=%ct.region)", the plugin framework handles parsing the output string, calling the plugin to extract values for a given event, and building the resolved string.
+
+Source plugins also provide an "id", which is globally unique and is used in capture files (see below).
+
+#### Extractor Plugin
+
+An extractor plugin focuses only on field extraction from events generated by other plugins, or by the core libraries. It does *not* provide an event source, but can extract fields from other event sources. An example is json field extraction, where a plugin might be able to extract fields from arbitrary json payloads.
+
+An extractor plugin provides an optional set of event sources. When the framework receives an event with an event source in the plugin's set of event sources, fields in expressions/Falco outputs will be extracted from events using the plugin. An extractor plugin can also *not* name a set of event sources. In this case, fields will be extracted from *all* events, regardless of source. In this case, the extractor plugin must detect the format of arbitrary payloads and be able to return NULL/no value when the payload is not supported.
+
+### Support for Plugin Events in Capture Files.
+
+libscap will define a new event type called "pluginevent" that contains two fields:
+
+* "plugin ID": This uniquely identifies the plugin that generated this event.
+* "event_data": This is a variable-length data buffer containing the event data, as returned by the plugin.
+
+Defining an event for plugins allows creating capture files from plugins. These capture files can be saved, read, filtered, etc, like any other capture file, allowing for later analysis/display/etc.
+
+### Plugins format
+
+Plugins are dynamic libraries (.so files in Unix, .dll files in windows) that export a minimum set of functions that the libraries will recognize.
+
+Plugins are versioned using semantic versioning to minimize regressions and compatibility issues.
+
+Plugins can be written in any language, as long as they export the required functions. Go, however, is the preferred language to write plugins, followed by C/C++.
+
+### Protecting from plugin issues
+
+The libraries will do everything possible to validate the data coming from the plugins and protect Falco and the other consumers from corrupted data. However, for performance reasons, plugins will be "trusted": they will run in the same thread and address space as Falco and they could crash the program. We assume that the user will be in control of plugin loading and will make sure only trusted plugins are loaded/packaged with Falco.
+
+### Plugin/Event Source registries
+
+Every source plugin requires its own, unique plugin ID to interoperate with Falco and the other plugins. The plugin ID will be used by the libs to properly process incoming events (for example, when saving events to file and loading them back), and by plugins to unambiguously recognize their dependencies.
+
+To facilitate the allocation and distribution of plugin IDs, we will require that plugin developers request IDs for their plugins to the Falco organization. The mechanism used for plugin allocation is not determined yet and will be discussed in the future.
+
+Similarly, plugin developers must register event sources with the Falco organization. This allows coordination between plugins that wish to provide compatible payloads, and to allow extractor plugins to know what data format is associated with a given event source.
+
+### golang plugin SDK
+
+To facilitate the development of plugins written in go, an SDK has been developed. We intend this SDK (and future SDKs for other languages) to be part of the Falco organization. For this reason, we submitted the following incubation request: https://github.com/falcosecurity/evolution/issues/62

+
+### Event Sources and Falco Rules
+
+Falco rules already have the notion of a "source", using the source property in rules objects, and there are currently two kinds of event sources: "syscall" and "k8s_audit". We will use the source property in Falco rules to map a given rule to the event source on which the rule runs.
+
+For example, given a plugin with source "aws_cloudtrail", and a Falco rule with source "aws_cloudtrail", the rule will be evaluated for any events generated by the plugin.
+
+Similarly, an extractor plugin that includes "aws_cloudtrail" in its set of event sources will have the opportunity to extract information from aws_cloudtrail events if a matching field is found in the rule's condition, exception, or output properties.
+
+This, combined with the restrictions below, allows a set of loaded rules files to contain a mix of rules for plugins as well as "core" syscall/k8s_audit events.
+
+We will also make a change to compile rules/macros/lists selectively based on the set of loaded plugins (specifically, their event sources), instead of unconditionally as Falco is started. This is especially important for macros, which do not contain a source property, but might contain fields that are only implemented by a given plugin.
+
+### Handling Duplicate/Overlapping Fields in Plugins/Libraries Core
+
+At an initial glance, adding plugins introduces the possibility of tens/hundreds of new filtercheck fields that could potentially overlap/conflict. For example, what happens if a plugin defines a "proc.name" field? However, the notion of "event source" makes these potential conflicts manageable.
+
+Remember that field extraction is always done in the context of an event, and each event can be mapped back to an event source. So we only need to ensure that filtercheck fields are distinct for a given event source. For example, it's perfectly valid for an AWS Cloudtrail plugin to define a proc.name field, as the events generated by that plugin are wholly separate from syscall events. For syscall events, the AWS Cloudtrail plugin is not involved and the core libraries extract the process name for the tid performing a syscall. For AWS Cloudtrail events, the core libraries are not involved in field extraction and is performed by the AWS Cloudtrail plugin instead.
+
+We only need to ensure the following:
+
+* That only one plugin is loaded at a time that exports a given event source. For example, the libraries can load either a gke-audit-bridge plugin with event source k8s_audit, or eks-audit-bridge with event source k8s_audit, but not both.
+* That for a mix of source and extractor plugins having the same event source, that the fields are distinct. For example, a source plugin with source k8s_audit can export ka.* fields, and an extractor plugin with event source k8s_audit can export a jevt.value[/...] field, and the appropriate plugin will be used to extract fields from k8s_audit events as fields are parsed from condition expressions/output format strings.
+
+### Plugin Versions and Falco Rules
+
+To allow rules files to document the plugin versions they are compatible with, we will add a new top-level field `required_plugin_versions` to the Falco rules file format. The field is optional, and if not provided no plugin compatibility checks will be performed. The syntax of `required_plugin_versions` will be the following:
+
+```yaml
+- required_plugin_versions:
+  - name: <plugin_name>
+    version: x.y.z
+  ...
+```
+
+Below required_plugin_versions is a list of objects, where each object has `name` and `version` properties. If a plugin is loaded, and if an entry in `required_plugin_versions` has a matching name, then the loaded plugin version must be semver compatible with the version property.
+
+Falco can load multiple rules files, and each file may contain its own `required_plugin_versions` property. In this case, name+version pairs across all files will be merged, and in the case of duplicate names all provided versions must be compatible.
+
+### Loading the plugins
+
+The mechanics of loading a plugin are implemented in the libraries and leverage the dynamic library functionality of the operating system (dlopen/dlsym in unix, LoadLibrary/GetProcAddress in Windows). The plugin loading code also ensures that:
+
+- the plugin is valid, i.e. that it exports the set of expected symbols
+- the plugin has an api version number that is compatible with the libraries instance
+- that only one source plugin is loaded at a time for a given event source
+- if a mix of source and extractor plugins are loaded for a given event source, that the exported fields have unique names that don't overlap across plugins
+
+#### Loading plugins in falcosecurity/libs
+
+At the libraries level, loading plugins is handled via the static method:
+
+```c++
+void sinsp_plugin::register_plugin(sinsp* inspector, string filepath, char* config, ...)
+```
+
+filepath points to a dynamic library containing code that exports plugin API functions. config contains arbitrary config content which is passed to init().
+
+Note that the code using the libraries is responsible for determining the location of plugin libraries and their configuration.
+
+#### Loading plugins in falcosecurity/falco
+
+Falco will control/configure loading plugins via the new "plugins" property in falco.yaml. Here's an example:
+
+```yaml
+plugins:
+  - name: aws_cloudtrail
+    library_path: aws_cloudtrail/plugin.so
+    init_config: "..."
+    open_params: "..."
+  - name: http_json
+    library_path: http_json/plugin.so
+    init_config_file: http_json/config.txt
+    open_params_file: http_json/params.txt
+
+# Optional
+load_plugins: [aws_cloudtrail]
+```
+
+A new "plugins" property in falco.yaml will define the set of plugins that can be loaded by Falco. The property contains a list of objects, with the following properties:
+
+* name: Only used for load_plugins, but by convention should be the same as the value returned by the name() api function.
+* library_path: a path to the shared library. The path can be relative, in which case it is relative to Falco's "share" directory under a "plugins" subdirectory e.g. /usr/share/falco/plugins.
+* init_config: If present, the exact configuration text that will be provided as an argument to the init() function.
+* init_config_file: If present, the provided file will be read and the contents will be provided as an argument to the init() function.
+* open_params: If present, the exact params text that will be provided as an argument to the open() function.
+* open_params_file: If present, the provided file will be read and the contents will be provided as an argument to the open() function.
+
+For a given yaml object in the plugins list, only one of init_config/init_config_file and one of open_params/open_params_file can be provided at a time.
+
+A new "load_plugins" property in falco.yaml will allow for loading a subset of the plugins defined in plugins. If present, only the plugins with the provided names will be loaded.
+
+### Examples
+
+We have an initial version working, consisting of:
+
+* A version of falcosecurity/libs that supports the [plugin framework](https://github.com/falcosecurity/libs/tree/new/plugin-system-api-additions)
+* Support code and examples for [writing plugins in go](https://github.com/mstemm/libsinsp-plugin-sdk-go/tree/new/plugin-system-api-additions)
+* A [cloudtrail](https://github.com/mstemm/plugins/tree/new/plugin-system-api-additions) plugin that can generate events from cloudtrail logs and extract fields from those events.
+* A version of Falco that uses all of the above to [load and evaluate rules with plugins](https://github.com/leogr/falco/tree/new/plugin-system-api-additions)
