# Adopters
Known end users with notable contributions to the project include:
* AWS
* IBM
* Red Hat
Falco is being used by numerous other companies, both large and small, to build higher layer products and services. The list includes but is not limited to:
* Equinix Metal
* IEEE
* Lowes
* Reckrut
* Yellow Pepper
* CTx
* Utikal
* Discrete Events
* Agritech Infra
This is a list of production adopters of Falco (in alphabetical order):
* [ASAPP](https://www.asapp.com/) - ASAPP is a pushing the boundaries of fundamental artificial intelligence research. We apply our research into AI-Native® products that make organizations, in the customer experience industry, highly productive, efficient, and effective—by augmenting human activity and automating workflows. We constantly monitor our workloads against different hazards and FALCO helps us extend our threat monitoring boundaries.
* [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
* [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
* [Deckhouse](https://deckhouse.io/) - Deckhouse Platform presents to you the opportunity to create homogeneous Kubernetes clusters anywhere and handles comprehensive, automagical management for them. It supplies all the add-ons you need for auto-scaling, observability, security, and service mesh. Falco is used as a part of the [runtime-audit-engine](https://deckhouse.io/documentation/latest/modules/650-runtime-audit-engine/) module to provide threats detection and enforce security compliance out of the box. By pairing with [shell-operator](https://github.com/flant/shell-operator) Falco can be configured by Kubernetes Custom Resources.
* [Fairwinds](https://fairwinds.com/) - [Fairwinds Insights](https://fairwinds.com/insights), Kubernetes governance software, integrates Falco to offer a single pane of glass view into potential security incidents. Insights adds out-of-the-box integrations and rules filter to reduce alert fatigue and improve security response. The platform adds security prevention, detection, and response capabilities to your existing Kubernetes infrastructure. Security and DevOps teams benefit from a centralized view of container security vulnerability scanning and runtime container security.
* [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
* [Giant Swarm](https://www.giantswarm.io/) - Giant Swarm manages Kubernetes clusters and infrastructure for enterprises across multiple cloud providers as well as several flavors of on-premises data centers. Our platform provisions and monitors pure "vanilla" Kubernetes clusters which can be augmented with managed solutions to many common Kubernetes challenges, including security. We use Falco for anomaly detection as part of our collection of entirely open-source tools for securing our own clusters, and offer the same capabilities to our customers as part of our [managed security offering](https://docs.giantswarm.io/app-platform/apps/security/).
* [GitLab](https://about.gitlab.com/direction/defend/container_host_security/) - GitLab is a complete DevOps platform, delivered as a single application, fundamentally changing the way Development, Security, and Ops teams collaborate. GitLab Ultimate provides the single tool teams need to find, triage, and fix vulnerabilities in applications, services, and cloud-native environments enabling them to manage their risk. This provides them with repeatable, defensible processes that automate security and compliance policies. GitLab includes a tight integration with Falco, allowing users to defend their containerized applications from attacks while running in production.
* [gVisor](https://gvisor.dev/) - gVisor secures Kubernetes, containers, and workloads via an alternate execution environment that handles system calls in user space, blocking security issues before they reach the underlying host. gVisor provides defense-in-depth, protection against untrusted code execution, and a secure-by-default Kubernetes experience where containers are a security boundary. Falco can be used with gVisor to detect unusual or suspicious activity using its threat detection engine on top of gVisor runtime execution information.
* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containers which could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.

* [Sumo Logic](https://www.sumologic.com/) - Sumo Logic provides a SaaS based log aggregation service that provides dashboards and applications to easily identify and analyze problems in your application and infrastructure. Sumo Logic provides native integrations for many CNCF projects, such as Falco, that allows end users to easily collect Falco events and analyze Falco events on DecSecOps focused dashboards.
* [Swissblock Technologies](https://swissblock.net/) At Swissblock we connect the dots by combining cutting-edge algorithmic trading strategies with in-depth market analysis. We route all Falco events to our control systems, both monitoring and logging. Being able to deeply analyse alerts, we can understand what is running on our Kubernetes clusters and check against security policies, specifically defined for each workload. A set of alarms notifies us in case of critical events, letting us react fast. In the near future we plan to build a little application to route Kubernetes internal events directly to Falco, fully leveraging Falco PodSecurityPolicies analyses.
* [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call probe. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-define infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
* [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)

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

[Falco](https://falco.org/) is a cloud native runtime security tool for Linux operating systems. It is designed to detect and alert on abnormal behavior and potential security threats in real-time.
### Latest releases
At its core, Falco is a kernel monitoring and detection agent that observes events, such as syscalls, based on custom rules. Falco can enhance these events by integrating metadata from the container runtime and Kubernetes. The collected events can be analyzed off-host in SIEM or data lake systems.
Read the [change log](CHANGELOG.md).
Falco, originally created by [Sysdig](https://sysdig.com), is an incubating project under the [Cloud Native Computing Foundation](https://cncf.io) (CNCF) used in production by various [organisations](https://github.com/falcosecurity/falco/blob/master/ADOPTERS.md).

For comprehensive information on the latest updates and changes to the project, please refer to the [change log](CHANGELOG.md). Additionally, we have documented the [release process](RELEASE.md) for delivering new versions of Falco.
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.
If a rule is violated in a system, Falco will send an alert notifying the user of the violation and its severity.
## Falco Repo: Powering the Core of The Falco Project
### Installing Falco
This is the main Falco repository which contains the source code for building the Falco binary. By utilizing its [libraries](https://github.com/falcosecurity/libs) and the [falco.yaml](falco.yaml) configuration file, this repository forms the foundation of Falco's functionality. The Falco repository is closely interconnected with the following *core* repositories:
If you would like to run Falco in **production** please adhere to the [official installation guide](https://falco.org/docs/installation/).
- [falcosecurity/libs](https://github.com/falcosecurity/libs): Falco's libraries are key to its fundamental operations, making up the greater portion of the source code of the Falco binary and providing essential features such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): Contains the official ruleset for Falco, providing pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins/): Falco plugins facilitate integration with external services, expand Falco's capabilities beyond syscalls and container events, and are designed to evolve with specialized functionality in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): Command-line utility for managing and interacting with Falco.

## Getting Started with Falco
### Developing
Carefully review and follow the [official guide and documentation](https://falco.org/docs/getting-started/).
Falco is designed to be extensible such that it can be built into cloud-native applications and infrastructure.
Considerations and guidance for Falco adopters:
Falco has a [gRPC](https://falco.org/docs/grpc/) endpoint and an API defined in [protobuf](https://github.com/falcosecurity/falco/blob/master/userspace/falco/outputs.proto).
The Falco Project supports various SDKs for this endpoint.
1. Understand dependencies: Assess the environment where you'll run Falco and consider kernel versions and architectures.
##### SDKs
2. Define threat detection objectives: Clearly identify the threats you want to detect and evaluate Falco's strengths and limitations.
3. Consider performance and cost: Assess compute performance overhead and align with system administrators or SREs. Budget accordingly.
4. Choose build and customization approach: Decide between the open source Falco build or creating a custom build pipeline. Customize the build and deployment process as necessary, including incorporating unique tests or approaches, to ensure a resilient deployment with fast deployment cycles.
5. Integrate with output destinations: Integrate Falco with SIEM, data lake systems, or other preferred output destinations to establish a robust foundation for comprehensive data analysis and enable effective incident response workflows.

## How to Contribute
### What can Falco detect?
Please refer to the [contributing guide](https://github.com/falcosecurity/.github/blob/main/CONTRIBUTING.md) and the [code of conduct](https://github.com/falcosecurity/evolution/CODE_OF_CONDUCT.md) for more information on how to contribute.
Falco can detect and alert on any behavior that involves making Linux system calls.
Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process.
For example, Falco can easily detect incidents including but not limited to:
- A shell is running inside a container or pod in Kubernetes.
- A container is running in privileged mode, or is mounting a sensitive path, such as `/proc`, from the host.
- A server process is spawning a child process of an unexpected type.
- Unexpected read of a sensitive file, such as `/etc/shadow`.
- A non-device file is written to `/dev`.
- A standard system binary, such as `ls`, is making an outbound network connection.
- A privileged pod is started in a Kubernetes cluster.

## Why is Falco in C++ rather than Go or {language}?
1. The first lines of code at the base of Falco were written some time ago, where Go didn't yet have the same level of maturity and adoption as today.
2. The Falco execution model is sequential and mono-thread due to the statefulness requirements of the tool, and so most of the concurrency-related selling points of the Go runtime would not be leveraged at all.
3. The Falco code deals with very low-level programming in many places (e.g. some headers are shared with the eBPF probe and the Kernel module), and we all know that interfacing Go with C is possible but brings tons of complexity and tradeoffs to the table.
4. As a security tool meant to consume a crazy high throughput of events per second, Falco needs to squeeze performance in all hot paths at runtime and requires deep control on memory allocation, which the Go runtime can't provide (there's also garbage collection involved).
5. Although Go didn't suit the engineering requirements of the core of Falco, we still thought that it could be a good candidate for writing Falco extensions through the plugin system. This is the main reason we gave special attention and high priority to the development of the plugin-sdk-go.
6. Go is not a requirement for having statically-linked binaries. In fact, we provide fully-static Falco builds since few years. The only issue with those is that the plugin system can't be supported with the current dynamic library model we currently have.
7. The plugin system has been envisioned to support multiple languages, so on our end maintaining a C-compatible codebase is the best strategy to ensure maximum cross-language compatibility.
8. In general, plugins have GLIBC requirements/dependencies because they have low-level C bindings required for dynamic loading. A potential solution for the future could be to also support plugin to be statically-linked at compilation time and so released as bundled in the Falco binary. Although no work started yet in this direction, this would solve most issues you reported and would provide a totally-static binary too. Of course, this would not be compatible with dynamic loading anymore, but it may be a viable solution for our static-build flavor of Falco.
9. Memory safety is definitely a concern and we try our best to keep an high level of quality even though C++ is quite error prone. For instance, we try to use smart pointers whenever possible, we build the libraries with an address sanitizer in our CI, we run Falco through Valgrind before each release, and have ways to stress-test it to detect performance regressions or weird memory usage (e.g. https://github.com/falcosecurity/event-generator). On top of that, we also have third parties auditing the codebase by time to time. None of this make a perfect safety standpoint of course, but we try to maximize our odds. Go would definitely make our life easier from this perspective, however the tradeoffs never made it worth it so far due to the points above.
10. The C++ codebase of falcosecurity/libs, which is at the core of Falco, is quite large and complex. Porting all that code to another language would be a major effort requiring lots of development resource and with an high chance of failure and regression. As such, our approach so far has been to choose refactors and code polishing instead, up until we'll reach an optimal level of stability, quality, and modularity, on that portion of code. This would allow further developments to be smoother and more feasibile in the future.

# Falco Release Process
Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
## Overview
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.
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:
A release happens every two months ([as per community discussion](https://github.com/falcosecurity/community/blob/master/meeting-notes/2020-09-30.md#agenda)), and we need to assign owners for each (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community). Note that hotfix releases can happen as soon as it is needed.
- Falco binary (userspace), includes `modern_bpf` driver object code (kernel space) starting with Falco 0.34.x releases
- Falco kernel driver object files, separate artifacts for `kmod` and `bpf` drivers, not applicable for `modern_bpf` driver (kernel space)
- Option 1: Kernel module (`.ko` files)
- Option 2: eBPF (`.o` files)
- Falco config and rules `.yaml` files (userspace)
- Falco plugins (userspace - optional)
> Note: Starting with Falco 0.34.x releases, the Falco userspace binary includes the `modern_bpf` driver object code during the linking process. This integration is made possible by the CO-RE (Compile Once - Run Everywhere) feature of the modern BPF driver. CO-RE allows the driver to function on kernels that have backported BTF (BPF Type Format) support or have a kernel version >= 5.8. For the older `kmod` and `bpf` drivers, separate artifacts are released for the kernel space. This is because these drivers need to be explicitly compiled for the specific kernel release, using the exact kernel headers. This approach ensures that Falco can support a wide range of environments, including multiple kernel versions, distributions, 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.
Falco publishes all sources, enabling users to audit the project's integrity and build kernel drivers for custom or unsupported kernels/distributions, specifically for non-modern BPF drivers (see [driverkit](https://github.com/falcosecurity/driverkit) for more information).
Finally, the release process follows a transparent process described in more detail in the following sections and the official [Falco guide and documentation](https://falco.org/) provide 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
> Note: This section specifically applies to non-modern BPF drivers.
The Falco Project publishes all drivers for each release for popular kernel versions / distros and `x86_64` and `aarch64` architectures to the Falco project's 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 sometimes fail to build the artifacts for a specific kernel version. 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 follows a release schedule of three times per year, with releases expected at the end of January, May, and September. Hotfix releases are issued as needed.
Changes and new features are organized into [milestones](https://github.com/falcosecurity/falco/milestones). The milestone corresponding to the next version represents the content that will be included in the upcoming release.
### Procedures
The release process is mostly automated, requiring only a few manual steps to initiate and complete.
Moreover, we assign owners for each release (typically pairing a new person with an experienced one). Assignees and due dates for releases are proposed during the [weekly community call](https://github.com/falcosecurity/community).
At a high level each Falco release needs to follow a pre-determined sequencing of releases and build order:
- [1 - 3] `libs` (+ `driver`) and `plugins` components releases
- [4] Falco driver pre-compiled object files push to Falco's Artifacts repo
- [5] Falco userspace binary release
Assignees are responsible for creating a Falco GitHub issue to track the release tasks and monitor the progress of the release. This issue serves as a central point for communication and provides updates on the release dates. You can refer to the [Falco v0.35 release](https://github.com/falcosecurity/falco/issues/2554) or [Libs Release (0.11.0+5.0.1+driver)](https://github.com/falcosecurity/libs/issues/1092) issues as examples/templates for creating the release issue.
Finally, on the proposed due date, the assignees for the upcoming release proceed with the processes described below.
Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
## Pre-Release Checklist
Before proceeding with the release, make sure to complete the following preparatory steps, which can be easily done using the GitHub UI:
Before cutting a release we need to do some homework in the Falco repository. This should take 5 minutes using the GitHub UI.
### 1. Release notes
- Find the previous release date (`YYYY-MM-DD`) by looking at the [Falco releases](https://github.com/falcosecurity/falco/releases)
- Find the LAST release (-1) and use `YYYY-MM-DD` as the day before of the [latest release](https://github.com/falcosecurity/falco/releases)
- Check the release note block of every PR matching the `is:pr is:merged closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+closed%3A%3EYYYY-MM-DD)
- Ensure the release note block follows the [commit convention](https://github.com/falcosecurity/.github/blob/master/CONTRIBUTING.md#commit-convention), otherwise fix its content
- Ensure the release note block follows the [commit convention](https://github.com/falcosecurity/falco/blob/master/CONTRIBUTING.md#commit-convention), otherwise fix its content
- If the PR has no milestone, assign it to the milestone currently undergoing release
- Check issues without a milestone (using `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD) ) and add them to the milestone currently undergoing release
- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD), if any, update those missing
- Check issues without a milestone (using [is:pr is:merged no:milestone closed:>YYYY-MM-DD](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD) filter) and add them to the milestone currently undergoing release
- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filters](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD), if any, fix them
### 2. Milestones
- Move the [tasks not completed](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Aopen) to a new minor milestone
### 3. Release branch
Assuming we are releasing a non-patch version (like: Falco 0.34.0), a new release branch needs to be created.
Its naming will be `release/M.m.x`; for example: `release/0.34.x`.
The same branch will then be used for any eventual cherry pick for patch releases.
For patch releases, instead, the `release/M.m.x` branch should already be in place; no more steps are needed.
Double check that any PR that should be part of the tag has been cherry-picked from master!
### 4. Release PR
The release PR is meant to be made against the respective `release/M.m.x` branch, **then cherry-picked on master**.
### 3. Release PR
- Double-check if any hard-coded version number is present in the code, it should be not present anywhere:
- If any, manually correct it then open an issue to automate version number bumping later
- Versions table in the `README.md` updates itself automatically
- Generate the change log using [rn2md](https://github.com/leodido/rn2md):
- Execute `rn2md -o falcosecurity -m <version> -r falco`
- In case `rn2md` emits error try to generate an GitHub OAuth access token and provide it with the `-t` flag
- Versions table in the `README.md` update itself automatically
- Generate the change log https://github.com/leodido/rn2md, or https://fs.fntlnz.wtf/falco/milestones-changelog.txt for the lazy people (it updates every 5 minutes)
- If you review timeout errors with `rn2md` try to generate an GitHub Oauth access token and use `-t`
- Add the latest changes on top the previous `CHANGELOG.md`
- Submit a PR with the above modifications
- Await PR approval
- Close the completed milestone as soon as the PR is merged into the release branch
- Cherry pick the PR on master too
## Publishing Pre-Releases (RCs and tagged development versions)
Core maintainers and/or the release manager can decide to publish pre-releases at any time before the final release
is live for development and testing purposes.
The prerelease tag must be formatted as `M.m.p-r`where `r` is the prerelease version information (e.g. `0.35.0-rc1`.)
To do so:
- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
- Use `M.m.p-r` both as tag version and release title.
- Check the "Set as a pre-release" checkbox and make sure "Set as the latest release" is unchecked
- It is recommended to add a brief description so that other contributors will understand the reason why the prerelease is published
- Publish the prerelease!
- The release pipeline will start automatically. Packages will be uploaded to the `-dev` bucket and container images will be tagged with the specified tag.
In order to check the status of the release pipeline click on the [GitHub Actions tab](https://github.com/falcosecurity/falco/actions?query=event%3Arelease) in the Falco repository and filter by release.
- Close the completed milestone as soon as the PR is merged
## Release
Assume `M.m.p` is the new version.
Now assume `x.y.z` is the new version.
### 1. Create the release with GitHub
### 1. Create a tag
- Once the release PR has got merged, and the CI has done its job on the master, git tag the new release
```
git pull
git checkout master
git tag x.y.z
git push origin x.y.z
```
> **N.B.**: do NOT use an annotated tag
- Wait for the CI to complete
### 2. Update the GitHub release
- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
- Use `M.m.p` both as tag version and release title
- Use `x.y.z` both as tag version and release title
- Use the following template to fill the release description:
```
<!-- Substitute M.m.p with the current release version -->

## Falco Components Versioning
This section provides more details around the versioning of the components that make up Falco's core. It can also be a useful guide for the uninitiated to be more informed about Falco's source. Because `libs` makes up the greater portion of the source code of the Falco binary and is the home of each of the kernel drivers and engines, the [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) is an excellent additional resource. In addition, the [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) provides similar details around Falco's plugins. `SHA256` checksums are provided throughout Falco's source code to empower the end user to perform integrity checks. All Falco releases also contain the sources as part of the packages.
### Falco repo (this repo)
- Falco version is a git tag (`x.y.z`), see [Procedures](#procedures) section. Note that the Falco version is a sem-ver-like schema, but not fully compatible with sem-ver.
- [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax and loading logic, and/or when `FALCO_ENGINE_CHECKSUM` has changed. The checksum is computed by considering the available rules fields (see currently supported [Falco fields](https://falco.org/docs/reference/rules/supported-fields/)), the event types (see currently supported [Falco events](https://falco.org/docs/reference/rules/supported-events/)), and the supported driver schema version. A checksum indicates that something 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. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. The version number must be incremented every time and only when a single change or an atomic group of changes - which meet the criteria described above - is included in the `master` branch. Thus, a version bump can occur multiple times during the development and testing phases of a given release cycle. A given version bump must not group multiple changes that occurred sporadically during the release cycle.
- 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).
- The driver version is not directly linked to the userspace components of the Falco binary. This is because of the clear separation between userspace and kernel space, which adds an additional layer of complexity. To address this, the concept of a `Default driver` has been introduced, allowing for implicit declaration of compatible driver versions. For example, if the default driver version is `5.0.1+driver`, Falco works with all driver versions >= 5.0.1 and < 6.0.0. 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.

> Cloud Native Runtime Security
### What is Falco?
Falco is a runtime security project originally created by Sysdig, Inc.
Falco was contributed to the CNCF in October 2018.
The CNCF now owns The Falco Project.
### What is Runtime Security?
Runtime security refers to an approach to preventing unwanted activity on a computer system.
With runtime security, an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
Runtime security is the practice of using detection tooling to detect unwanted behavior, such that it can then be prevented using prevention techniques.
Runtime security is a holistic approach to defense, and useful in scenarios where prevention tooling either was unaware of an exploit or attack vector, or when defective applications are ran in even the most secure environment.
### What does Falco do?
Falco consumes signals from the Linux kernel, and container management tools such as Docker and Kubernetes.
Falco parses the signals and asserts them against security rules.
If a rule has been violated, Falco triggers an alert.
### How does Falco work?
Falco traces kernel events and reports information about the system calls being executed at runtime.
Falco leverages the extended berkley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel.
Falco enriches these kernel events with information about containers running on the system.
Falco also can consume signals from other input streams such as the containerd socket, the Kubernetes API server and the Kubernetes audit log.
At runtime, Falco will reason about these events and assert them against configured security rules.
Based on the severity of a violation an alert is triggered.
These alerts are configurable and extensible, for instance sending a notification or [plumbing through to other projects like Prometheus](https://github.com/falcosecurity/falco-exporter).
### Benefits of using Falco
- **Strengthen Security** Create security rules driven by a context-rich and flexible engine to define unexpected application behavior.
- **Reduce Risk** Immediately respond to policy violation alerts by plugging Falco into your current security response workflows and processes.
- **Leverage up-to-date Rules** Alert using community-sourced detections of malicious activity and CVE exploits.
### Falco and securing Kubernetes
Securing Kubernetes requires putting controls in place to detect unexpected behavior that could be malicious or harmful to a cluster or application(s).
Examples of malicious behavior include:
- Exploits of unpatched and new vulnerabilities in applications or Kubernetes itself.
- Insecure configurations in applications or Kubernetes itself.
- Leaked or weak credentials or secret material.
- Insider threats from adjacent applications running at the same layer.
Falco is capable of [consuming the Kubernetes audit logs](https://kubernetes.io/docs/tasks/debug-application-cluster/falco/#use-falco-to-collect-audit-events).
By adding Kubernetes application context, and Kubernetes audit logs teams can understand who did what.
### Writing about Falco

- the falco project
- the Falco project
### Encouraged Phrasing
Below are phrases that the project has reviewed, and found to be effective ways of messaging Falco's value add.
Even when processes are in place for vulnerability scanning and implementing pod security and network policies, not every risk will be addressed. You still need mechanisms to confirm these security barriers are effective, help configure them, and provide with a last line of defense when they fail.
##### Falco as a factory
This term refers to the concept that Falco is a stateless processing engine. A large amount of data comes into the engine, but meticulously crafted security alerts come out.
##### The engine that powers...
Falco ultimately is a security engine. It reasons about signals coming from a system at runtime, and can alert if an anomaly is detected.
##### Anomaly detection
This refers to an event that occurs with something unsual, concerning, or odd occurs.
We can associate anomalies with unwanted behavior, and alert in their presence.
##### Detection tooling
Falco does not prevent unwanted behavior.
Falco however alerts when unusual behavior occurs.
This is commonly referred to as **detection** or **forensics**.

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.

# For this reason, we have to mirror their release after

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

Hello, this is the Falco tester container.
How to use.
The default commands for the Falco tester image reports usage and environment info.
* docker run falcosecurity/falco-tester
* docker run falcosecurity/falco-tester usage
It supports bash.
* docker run -ti falcosecurity/falco-tester bash
To run Falco regression tests you need to provide:
- the docker socket
- the boot directory
- the source directory
- the directory where Falco has been built
- the environment variable FALCO_VARIABLE set to the value obtained during the Falco's build
Assuming you are running it from the Falco root directory, you can run it as follows.
* docker run -v /boot:/boot:ro -v /var/run/docker.sock:/var/run/docker.sock -v $PWD/..:/source -v $PWD/build:/build -e FALCO_VERSION=<current_falco_version> falcosecurity/falco-tester test
How to build.
* cd docker/tester && DOCKER_BUILDKIT=1 docker build -t falcosecurity/falco-tester .
Environment.
* python ${pythonversion}
* ${pipversion}
* avocado ${avocadoversion}
* ${dockerversion}

- To support different queuing systems than the default (round-robin) one
- To support different queing systems than the default (round-robin) one
- To support queuing mechanisms for message retransmission
- Users can have a local gRPC relay server along with Falco that multiplexes connections and handles retires and backoff

The PSP is converted into a set of Falco rules which can be either saved as a file for later use/inspection, or loaded directly so that they can monitor system calls and k8s audit activity.

One significant change will be that filter fields can extract more than one "value" per event, and we'll need to define new operators to perform set comparisons between values in an event and values in the comparison right-hand-side.
