ADOPTERS.md

@@ -24,25 +24,31 @@ This is a list of production adopters of Falco (in alphabetical order):
 
 * [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).

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.

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.

 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 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.

 # Falco Release Process
 
-Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
 
-Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released.
+## 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).
 
-Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
+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.

+## 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 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.

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

+* We use `Dockerfile` to build the `centos7` Falco builder image.
+* We use `modern-falco-builder.Dockerfile` to build Falco with the modern probe and return it as a Dockerfile output. This Dockerfile doesn't generate a Docker image but returns as output (through the `--output` command):
+  * Falco `tar.gz`.
+  * Falco `deb` package.
+  * Falco `rpm` package.
+  * Falco build directory, used by other CI jobs.

+# 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]
+#   ^    ^     ^     ^     ^     ^      ^      ^       ^       ^       ^

+#
+# 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.

+# --- [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)

+#                   |     |  |        |  |  |  |
+#       BUFFERs     0     1  2        3  4  5  6

+#       BUFFERs     0     0  1        1  2  2  3
+#
+# Please note that we need 4 buffers, 3 buffers are associated with CPU pairs, the last
+# one is mapped with just 1 CPU since we have an odd number of CPUs.
+#
+# - `0` or `MAX_NUMBER_ONLINE_CPUs` mean a syscall buffer shared between all CPUs, so 1 buffer
+#
+#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)

+#       BUFFERs     0     0  0        0  0  0  0
+#
+# Moreover you can combine this param with `syscall_buf_size_preset`
+# index, for example, you could create a huge single syscall buffer
+# shared between all your online CPUs of 512 MB (so `syscall_buf_size_preset=10`).
+#
+# --- [Suggestions]
+#
+# We chose index `2` (so one syscall buffer for each CPU pair) as default because the modern bpf probe
+# follows a different memory allocation strategy with respect to the other 2 drivers (bpf and kernel module).
+# By the way, you are free to find the preferred configuration for your system.
+# Considering a fixed `syscall_buf_size_preset` and so a fixed buffer dimension:

+# 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

 ### 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 managable.
+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.

+# Artifacts distribution
+
+This proposal aims to define guidelines for the official distribution of artifacts published by Falcosecurity. 
+
+Therefore, to create a unified management of the distribution of artifacts, this document supersedes (for the parts concerning the distributions of artifacts) proposals [Falco Artifacts Scope - Part 1](https://github.com/falcosecurity/falco/blob/master/proposals/20200506-artifacts-scope-part-1.md), [Falco Artifacts Scope - Part 2](https://github.com/falcosecurity/falco/blob/master/proposals/20200506-artifacts-scope-part-2.md), and [Falco Drivers Storage S3](https://github.com/falcosecurity/falco/blob/master/proposals/20201025-drivers-storage-s3.md) and also extends and generalizes the proposal [Falco Rules and Plugin distribution](https://github.com/falcosecurity/falcoctl/blob/main/proposals/20220916-rules-and-plugin-distribution.md) for [falcoctl](https://github.com/falcosecurity/falcoctl).
+
+## Goals
+
+- Allow users to consume artifacts in a consistent way
+- Define official artifacts
+- Unify distribution mechanism, infrastructure and tooling
+- Provide generic guidelines applicable to any artifact to be distributed
+
+## Non-Goals
+
+- Infra/CI implementation details
+- Supply chain security topics
+
+## Proposal
+
+With officially supported artifacts, we mean that set of artifacts published 
+by Falcosecurity as part of Falco or its ecosystem.
+
+At the time of writing, the Falcosecurity organization distributes several kinds of artifacts in the form of files or container images. They include:
+- Installation packages
+- Helm charts
+- Drivers (eg, kmod, eBPF)
+- Rule files
+- Plugins
+- Other kinds may be added in the future.
+
+Features shipped with **official artifacts are intended for general availability(GA)**, unless otherwise specified (eg. if experimental or non-production ready features are present, they must be indicated in the release notes). 
+
+The same artifacts can be distributed via multiple distribution channels, and each channel can be mirrored. **The [falco.org](https://falco.org/) website must list all official distribution channels and mirrors**. Any distribution channel not listed on our official website must not be considered part of the official distribution. However, maintainers can still use other channels for experimentation or incubating projects eventually.
+
+### Distribution channels
+
+#### HTTP Distribution
+
+Distributing artifacts as plain files via HTTP is mostly intended for **humans, simple and legacy clients** (e.g., a shell script that downloads a file). 
+
+The allowed publishing channels are:
+- **[download.falco.org](https://download.falco.org/)** where most of the file artifacts lives
+- **endpoints made available by GitHub** for the Falcosecurity organization (e.g., release download URL, GitHub pages, etc.).
+
+Typically, all official artifacts that can be shipped as plain files should be published at [download.falco.org](https://download.falco.org/) and available for download. 
+
+Using the GitHub platform is allowed as an alternative assuming that artifacts are published under the Falcosecurity organization and the GitHub platform usage limitations are being respected (a notable example is publishing a [Helm chart index file using GitHub pages](https://falcosecurity.github.io/charts/)).
+
+It is allowed to publish other non-official artifacts (for example, [development builds](https://download.falco.org/?prefix=packages/bin-dev/)), taking that those are correctly denoted.
+
+Introducing other HTTP channels is discouraged. Providing mirrors is discouraged unless required for technical reasons.
+
+#### OCI Distribution
+
+Some artifacts are in the form of Open Container Initiative (OCI) images and require OCI registries to be distributed. Nevertheless, since the [OCI Distribution Spec](https://specs.opencontainers.org/distribution-spec/?v=v1.0.0) allows any content, even regular files can be stored in OCI registries and distributed likewise. Notably, the [Helm project in early 2022 started storing charts in OCI](https://helm.sh/blog/storing-charts-in-oci/) registries. One our tool [falcoctl did the same](https://github.com/falcosecurity/falcoctl/blob/main/proposals/20220916-rules-and-plugin-distribution.md) later.
+
+Distributing artifacts via OCI registries is intended for all compatible consumers (i.e., [falcoctl](https://github.com/falcosecurity/falcoctl)). It is **allowed and encouraged for any artifacts**. All official artifacts should be published so.
+
+The allowed publishing channels are:
+
+
+| Registry | Name | Account URL |
+| -------- | -------- | -------- |
+| `docker.io`    | Docker Hub     | https://hub.docker.com/u/falcosecurity |
+| `ghcr.io`    | Github Packages Container registry     | https://github.com/orgs/falcosecurity/packages |
+
+
+Both channels are equivalent and may publish the same artifacts. However, for historical reasons and to avoid confusion, the **`docker.io` registry should only be used for container images** and not for other kinds of artifacts (e.g., plugins, rules, etc.).
+
+
+Mirrors are allowed and encouraged if they facilitate artifacts consumption by our users. This proposal reccomends to enable mirrors on the major public OCI registry, such as [Amazon ECR](https://gallery.ecr.aws/) (which is already implentend in our infra at the time of writing).
+
+
+Official **channels and mirrors must be listed at [falco.org](https://falco.org/)**. 
+
+It is allowed to publish other non-official artifacts, even using image tags, taking that those are correctly denoted.
+
+
+#### Other channels
+
+At the time of writing, no other distribution channels are present or needed. However, in case a new kind of artifact will require a particular distribution mechanism (for example, in case an existing package manager system need to consume the artifact using its protocol), the rule of thumb is first to use the available GitHub features for the Falcosecurity organization, if possible. Users will quickly recognize the association between the artifact and the publisher (i.e., falcosecurity), and for that reason is usually preferable.
+
+In all other cases, introducing a new distribution channel must require extensive discussion among maintainers. Nevertheless, **introducing too many distribution channels is discouraged** because it disperses the effort and can mislead users. 
+
+
+### Publishing
+
+#### Source repository
+
+Artifacts must always be built starting from the originating source code and thru an auditable and reproducible process that runs on our infra. It's recommended that the naming and versioning of the published artifact consistently match the originating repository's naming and versioning. For example, the package `falco-0.33.0-x86_64.tar.gz` must match the source code of the git tag [0.33.0](https://github.com/falcosecurity/falco/tree/0.33.0) of the [falco](https://github.com/falcosecurity/falco) repository.
+
+It's recommended that **each repository publish only one kind of artifact** associated with it. 
+
+Exceptions are allowed for:
+ - mono repos (notably [charts](https://github.com/falcosecurity/charts) and [plugins](https://github.com/falcosecurity/plugins)), 
+ - or whenever technical constraints impose a different approach (notably, our Driver Build Grid lives on [test-infra](https://github.com/falcosecurity/test-infra), but the source code is in [libs](https://github.com/falcosecurity/libs)).
+
+Exceptions should be documented to avoid the users and contributors might be confused.
+
+#### Namespacing
+
+As a general rule, to avoid name clashing among different projects under the Falcosecurity organization, all **published artifacts should reflect the originating repository name** in their publishing URL. For example, all artifacts generated by the [falcosecurity/plugins](https://github.com/falcosecurity/plugins) repository should have `falcosecurity/plugins` as the URL's base path.
+
+Exceptions are allowed for:
+- legacy and already published artifacts (to avoid disruption);
+- justified technical reasons.
+
+#### Versioning
+
+All published artifacts must be labeled with version numbers following the **[Semantic Versioning 2 specification](https://semver.org/)**.
+
+For the [HTTP Distribution](#http-distribution), the version number must be reflected in the file name (including build metadata like the targeted arch and platform).
+
+For the [OCI Distribution](#oci-distribution), the version number must be reflected in the image tag (build metadata may be avoided if included in the manifest).
+
+### Tooling
+
+Tooling is essential to deliver a consistent and straightforward UX to our users since the limited set of distribution channels is acceptable to provide just one (or a limited set of) tool(s) capable of working with various artifacts published by the Falcosecurity organization.
+
+In this regard, this proposal follows up the [Falco Rules and Plugin distribution](https://github.com/falcosecurity/falcoctl/blob/main/proposals/20220916-rules-and-plugin-distribution.md) proposal and recommends to use of **[falcoctl](https://github.com/falcosecurity/falcoctl) as the tool to managing artifacts specifically intended for Falco**. The tool's design should consider that other kinds of artifacts may be added in the future.
+
+Likewise, relying on existing **third-party tools for generic or well-known kinds of artifacts** (for example, Helm charts) is recommended.
+
+### Ecosystem
+
+Compatibility with other tools on the broader cloud native ecosystem should be considered when dealing with artifacts and their distribution.
+
+It is also recommended to use third-party solutions and projects that facilitate our users' discovery of published artifacts (for example, https://artifacthub.io/).
+
+
+## Action items
+
+The following subsections indicate major action items to be executed in order to transition from the current to the desiderate state of the art, as noted in this proposal.
+
+### Move [Falco rules](https://github.com/falcosecurity/falco/tree/master/rules) to their own repo
+
+Falco rules files (i.e., the ruleset for the data source syscall) are currently only distributed in bundles with Falco. However, now falcoctl can manage rules artifacts so that we can ship them separately.
+
+The benefits of having rules living in their repository are:
+  - dedicated versioning
+  - rules release will not be tied anymore to a Falco release (e.g., no need to wait for the scheduled Falco release to publish a new rule aiming to detect the latest published CVE)
+  - consistent installation/update mechanism with other rulesets (plugins rules are already published in their repository and can be consumed by falcoctl)
+
+Note that this change will not introduce a breaking change: Falco will continue shipping the default ruleset by including the published ruleset package.
+
+### Make `falcoctl` official
+
+Considering the centrality of falcoctl for managing official artifacts for Falco, the falcoctl project must be promoted to "Official" status, and its repository assumed to be [core](https://github.com/falcosecurity/evolution/blob/main/GOVERNANCE.md#core-repositories).
+
+### Deprecate `falco-driver-loader`
+
+At the time of writing, `falco-driver-loader` is a shell script shipped in a bundle with Falco that has the responsibility of installing a driver by either downloading it from our distribution channels or trying to build it on-the-fly.
+
+Our experience showed all the limitations of this approach, and it's now clear that such as script is hard to maintain. Furthermore, its responsibility overlaps with our aim to use `falcoctl` as the tool for managing artifacts.
+
+Thus, this proposal mandates to deprecate of `falco-driver-loader` in favor of `falcoctl.`
+
+However, to avoid user disruption and breaking legacy use case, it's recommended to provide still a faced script that exposes the same command line usage of `falco-driver-loader` but forward its execution to the new tool `falcoctl`.
+
+This implicitly requires that `falcoctl` be shipped in a bundle with Falco.
+
+### Update the documentation
+
+This proposal mandates making use of official documentation (i.e., falco.org) to state official items, such as artifacts, distribution channels, and mirrors.
+
+For that reason, it becomes imperative to update the documentation periodically concerning the list of officially supported distribution channels and mirrors.
+
+### Usage of GitHub Packages
+
+Since GitHub is the primary platform where the Falcosecurity organization hosts its code and infrastructure, its provided features should be preferred whenever possible.
+
+This proposal recommends using the GitHub Packages feature when the need to distribute a new kind of artifact arises. Such as convention should be adopted among all repositories of the organization.
