This file documents all notable changes to Falco. The release numbering uses [semantic versioning](http://semver.org).
## v0.17.0
Released 2019-07-31
## Major Changes
* **The set of supported platforms has changed**. Switch to a reorganized builder image that uses Centos 7 as a base. As a result, falco is no longer supported on Centos 6. The other supported platforms should remain the same [[#719](https://github.com/falcosecurity/falco/pull/719)]
## Minor Changes
* When enabling rules within the falco engine, use rule substrings instead of regexes. [[#743](https://github.com/falcosecurity/falco/pull/743)]
* Additional improvements to the handling and display of rules validation errors [[#744](https://github.com/falcosecurity/falco/pull/744)] [[#747](https://github.com/falcosecurity/falco/pull/747)]
## Bug Fixes
* Fix a problem that would cause prevent container metadata lookups when falco was daemonized [[#731](https://github.com/falcosecurity/falco/pull/731)]
* Allow rule priorites to be expressed as lowercase and a mix of lower/uppercase [[#737](https://github.com/falcosecurity/falco/pull/737)]
## Rule Changes
* Fix a parentheses bug with the `shell_procs` macro [[#728](https://github.com/falcosecurity/falco/pull/728)]

## v0.16.0
Released 2019-07-12
## Major Changes
* Clean up error reporting to provide more meaningful error messages along with context when loading rules files. When run with -V, the results of the validation ("OK" or error message) are sent to standard output. [[#708](https://github.com/falcosecurity/falco/pull/708)]
* Improve rule loading performance by optimizing lua parsing paths to avoid expensive pattern matches. [[#694](https://github.com/falcosecurity/falco/pull/694)]
* Bump falco engine version to 4 to reflect new fields `ka.useragent`, others. [[#710](https://github.com/falcosecurity/falco/pull/710)] [[#681](https://github.com/falcosecurity/falco/pull/681)]
* Add Catch2 as a unit testing framework. This will add additional coverage on top of the regression tests using Avocado. [[#687](https://github.com/falcosecurity/falco/pull/687)]

* Partial changes towards lua syntax formatting. No particular formatting enforced yet, though. [[#718](https://github.com/falcosecurity/falco/pull/718)]
* Partial changes towards yaml syntax formatting. No particular formatting enforced yet, though. [[#714](https://github.com/falcosecurity/falco/pull/714)]
* Add cmake syntax formatting. [[#703](https://github.com/falcosecurity/falco/pull/703)]
* Token bucket unit tests and redesign. [[#692](https://github.com/falcosecurity/falco/pull/692)]

* Move Kubernetes Response Engine to own repo: The Kubernetes Response Engine is now in its [own github repository](https://github.com/falcosecurity/kubernetes-response-engine). [[#539](https://github.com/falcosecurity/falco/pull/539)]
* Updated Puppet Module: An all-new puppet module compatible with puppet 4 with a smoother installation process and updated package links. [[#537](https://github.com/falcosecurity/falco/pull/537)] [[#543](https://github.com/falcosecurity/falco/pull/543)] [[#546](https://github.com/falcosecurity/falco/pull/546)]
* RHEL-based falco image: Provide dockerfiles that use RHEL 7 as the base image instead of debian:unstable. [[#544](https://github.com/falcosecurity/falco/pull/544)]
## Minor Changes
* ISO-8601 Timestamps: Add the ability to write timestamps in ISO-8601 w/ UTC, and use this format by default when running falco in a container [[#518](https://github.com/falcosecurity/falco/pull/518)]
* Docker-based builder/tester: You can now build Falco using the [falco-builder](https://falco.org/docs/source/#build-using-falco-builder-container) docker image, and run regression tests using the [falco-tester](https://falco.org/docs/source/#test-using-falco-tester-container) docker image. [[#522](https://github.com/falcosecurity/falco/pull/522)] [[#584](https://github.com/falcosecurity/falco/pull/584)]
* Several small docs changes to improve clarity and readibility [[#524](https://github.com/falcosecurity/falco/pull/524)] [[#540](https://github.com/falcosecurity/falco/pull/540)] [[#541](https://github.com/falcosecurity/falco/pull/541)] [[#542](https://github.com/falcosecurity/falco/pull/542)]
* Add instructions on how to enable K8s Audit Logging for kops [[#535](https://github.com/falcosecurity/falco/pull/535)]
* Add a "stale issue" bot that marks and eventually closes old issues with no activity [[#548](https://github.com/falcosecurity/falco/pull/548)]
* Improvements to sample K8s daemonset/service/etc files [[#562](https://github.com/falcosecurity/falco/pull/562)]
## Bug Fixes
* Fix regression that broke json output [[#581](https://github.com/falcosecurity/falco/pull/581)]
* Fix errors when building via docker from MacOS [[#582](https://github.com/falcosecurity/falco/pull/582)]
## Rule Changes
* **Tag rules using Mitre Attack Framework**: Add tags for all relevant rules linking them to the [MITRE Attack Framework](https://attack.mitre.org). We have an associated [blog post](https://sysdig.com/blog/mitre-attck-framework-for-container-runtime-security-with-sysdig-falco/). [[#575](https://github.com/falcosecurity/falco/pull/575)] [[#578](https://github.com/falcosecurity/falco/pull/578)]
* New rules for additional use cases: New rules `Schedule Cron Jobs`, `Update Package Repository`, `Remove Bulk Data from Disk`, `Set Setuid or Setgid bit`, `Detect bash history deletion`, `Create Hidden Files or Directories` look for additional common follow-on activity you might see from an attacker. [[#578](https://github.com/falcosecurity/falco/pull/578)] [[#580](https://github.com/falcosecurity/falco/pull/580)]
* Allow docker's "exe" (usually part of docker save/load) to write to many filesystem locations [[#552](https://github.com/falcosecurity/falco/pull/552)]
* Let puppet write below /etc [[#563](https://github.com/falcosecurity/falco/pull/563)
* Add new `user_known_write_root_conditions`, `user_known_non_sudo_setuid_conditions`, and `user_known_write_monitored_dir_conditions` macros to allow those rules to be easily customized in user rules files [[#563](https://github.com/falcosecurity/falco/pull/563)] [[#566](https://github.com/falcosecurity/falco/pull/566)]
* Better coverage and exceptions for rancher [[#559](https://github.com/falcosecurity/falco/pull/559)]
* Allow prometheus to write to its conf directory under etc [[#564](https://github.com/falcosecurity/falco/pull/564)]
* Better coverage and exceptions for openshift/related tools [[#567](https://github.com/falcosecurity/falco/pull/567)] [[#573](https://github.com/falcosecurity/falco/pull/573)]
* Better coverage for cassandra/kubelet/kops to reduce FPs [[#551](https://github.com/falcosecurity/falco/pull/551)]
* Better coverage for docker, openscap to reduce FPs [[#573](https://github.com/falcosecurity/falco/pull/573)]
* Better coverage for fluentd/jboss to reduce FPs [[#590](https://github.com/falcosecurity/falco/pull/590)]
* Add `ash` (Alpine Linux-related shell) as a shell binary [[#597](https://github.com/falcosecurity/falco/pull/597)]

## Code of Conduct
Falco has a
[Code of Conduct](CODE_OF_CONDUCT)
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 Sysdig 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 `/assign @theirname`.
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.
## 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'
```

Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by [sysdigs](https://github.com/draios/sysdig) system call capture infrastructure, 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.
## Overview
Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by [sysdigs](https://github.com/draios/sysdig) system call capture infrastructure, 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.
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).
#### What kind of behaviors 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:
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, you can easily detect things like:
- 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.

#### How Falco Compares to Other Security Tools like SELinux, Auditd, etc.
### Installing Falco
A 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.

License Terms

Falco is licensed to you under the [Apache 2.0](./COPYING) open source license.
Contributing
Contributor License Agreements
---
See the [CONTRIBUTING.md](./CONTRIBUTING.md).
### Background
We are formalizing the way that we accept contributions of code from the contributing community. We must now ask that contributions to falco be provided subject to the terms and conditions of a [Contributor License Agreement (CLA)](./cla). The CLA comes in two forms, applicable to contributions by individuals, or by legal entities such as corporations and their employees. We recognize that entering into a CLA with us involves real consideration on your part, and weve tried to make this process as clear and simple as possible.
Weve modeled our CLA off of industry standards, such as [the CLA used by Kubernetes](https://github.com/kubernetes/kubernetes/blob/master/CONTRIBUTING.md). Note that this agreement is not a transfer of copyright ownership, this simply is a license agreement for contributions, intended to clarify the intellectual property license granted with contributions from any person or entity. It is for your protection as a contributor as well as the protection of falco; it does not change your rights to use your own contributions for any other purpose.
For some background on why contributor license agreements are necessary, you can read FAQs from many other open source projects:
- [Djangos excellent CLA FAQ](https://www.djangoproject.com/foundation/cla/faq/)
- [A well-written chapter from Karl Fogels Producing Open Source Software on CLAs](http://producingoss.com/en/copyright-assignment.html)
- [The Wikipedia article on CLAs](http://en.wikipedia.org/wiki/Contributor_license_agreement)
As always, we are grateful for your past and present contributions to falco.
### What do I need to do in order to contribute code?
**Individual contributions**: Individuals who wish to make contributions must review the [Individual Contributor License Agreement](./cla/falco_contributor_agreement.txt) and indicate agreement by adding the following line to every GIT commit message:
```

```
Use your real name; pseudonyms or anonymous contributions are not allowed.
**Corporate contributions**: Employees of corporations, members of LLCs or LLPs, or others acting on behalf of a contributing entity, must review the [Corporate Contributor License Agreement](./cla/falco_corp_contributor_agreement.txt), must be an authorized representative of the contributing entity, and indicate agreement to it on behalf of the contributing entity by adding the following lines to every GIT commit message:

4. You represent to Draios/Sysdig that You own or have the right to contribute Your Contributions to Draios/Sysdig, and that You are legally entitled to grant the license set forth above.
5. You represent that each of Your Contributions is Your original creation (see section 7 for submissions on behalf of others). You represent that Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which You are personally aware and which are associated with any part of Your Contributions. You represent that Your sign-off indicating assent to this Agreement includes the real name of a natural person who is an authorized representative of You, and not a pseudonym, and that You are not attempting or making an anonymous Contribution.
6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions to Draios/Sysdig on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON- INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
7. If You wish to submit work that is not Your original creation, You may submit it to Draios/Sysdig separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which You are aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
8. You agree to notify Draios/Sysdig of any facts or circumstances of which you become aware that would make these representations inaccurate in any respect.
9. You understand and agree that this project and Your Contribution are public and that a record of the contribution, including all personal information that You submit with it, including the sign-off of Your authorized representative, may be stored by Draios/Sysdig indefinitely and may be redistributed to others. You understand and agree that Draios/Sysdig has no obligation to use any Contribution in any Draios/Sysdig project or product, and Draios/Sysdig may decline to accept Your Contributions or Draios/Sysdig may remove Your Contributions from Draios/Sysdig projects or products at any time without notice. You understand and agree that Draios/Sysdig is not and will not pay You any form of compensation, in currency, equity or otherwise, in exchange for Your Contributions or for Your assent to this Agreement. You understand and agree that You are independent of Draios/Sysdig and You are not, by entering into this Agreement or providing Your Contributions, becoming employed, hired as an independent contractor, or forming any other relationship with Draios/Sysdig relating to employment, compensation or ownership or involving any fiduciary obligation.

#[=======================================================================[.rst:
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.

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}

This page describes how to get [Kubernetes Auditing](https://kubernetes.io/docs/tasks/debug-application-cluster/audit) working with Falco.
Either using static audit backends in Kubernetes 1.11, or in Kubernetes 1.13 with dynamic sink which configures webhook backends through an AuditSink API object.
# Introduction
<!-- toc -->
The files in this directory can be used to configure k8s audit logging. The relevant files are:
- [Instructions for Kubernetes 1.11](#instructions-for-kubernetes-111)
* [Deploy Falco to your Kubernetes cluster](#deploy-falco-to-your-kubernetes-cluster)
* [Define your audit policy and webhook configuration](#define-your-audit-policy-and-webhook-configuration)
* [Restart the API Server to enable Audit Logging](#restart-the-api-server-to-enable-audit-logging)
* [Observe Kubernetes audit events at falco](#observe-kubernetes-audit-events-at-falco)
- [Instructions for Kubernetes 1.13](#instructions-for-kubernetes-113)
* [Deploy Falco to your Kubernetes cluster](#deploy-falco-to-your-kubernetes-cluster-1)
* [Restart the API Server to enable Audit Logging](#restart-the-api-server-to-enable-audit-logging-1)
* [Deploy AuditSink objects](#deploy-auditsink-objects)
* [Observe Kubernetes audit events at falco](#observe-kubernetes-audit-events-at-falco-1)
- [Instructions for Kubernetes 1.13 with dynamic webhook and local log file](#instructions-for-kubernetes-113-with-dynamic-webhook-and-local-log-file)
* [audit-policy.yaml](./audit-policy.yaml): The k8s audit log configuration we used to create the rules in [k8s_audit_rules.yaml](../../rules/k8s_audit_rules.yaml). You may find it useful as a reference when creating your own K8s Audit Log configuration.
* [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`. You may find it useful as a starting point when deciding how to route audit events to the embedded webserver within falco.
<!-- tocstop -->
These files are only needed when using Minikube, which doesn't currently
have the ability to provide an audit config/webhook config directly
from the minikube commandline. See [this issue](https://github.com/kubernetes/minikube/issues/2741) for more details.
## Instructions for Kubernetes 1.11
* [apiserver-config.patch.sh](./apiserver-config.patch.sh): A script that changes the configuration file `/etc/kubernetes/manifests/kube-apiserver.yaml` to add necessary config options and mounts for the kube-apiserver container that runs within the minikube vm.
The main steps are:
A way to use these files with minikube to run falco and enable audit logging would be the following:
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
#### Start Minikube with Audit Logging Enabled
### Deploy Falco to your Kubernetes cluster
Run the following to start minikube with Audit Logging Enabled:
Follow the [Kubernetes Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a falco service account, service, configmap, and daemonset.
```
minikube start --kubernetes-version v1.11.0 --mount --mount-string $PWD:/tmp/k8s_audit_config --feature-gates AdvancedAuditing=true
```
### Define your audit policy and webhook configuration
#### Create a Falco DaemonSet and Supporting Accounts/Services
The files in this directory can be used to configure Kubernetes audit logging. The relevant files are:
Follow the [K8s Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a falco service account, service, configmap, and daemonset.
* [audit-policy.yaml](./audit-policy.yaml): The Kubernetes audit log configuration we used to create the rules in [k8s_audit_rules.yaml](../../rules/k8s_audit_rules.yaml).
* [webhook-config.yaml.in](./webhook-config.yaml.in): A (templated) webhook configuration that sends audit events to an ip associated with the falco service, port 8765. It is templated in that the *actual* IP is defined in an environment variable `FALCO_SERVICE_CLUSTERIP`, which can be plugged in using a program like `envsubst`.
#### Configure Audit Logging with a Policy and Webhook
Run the following to fill in the template file with the `ClusterIP` IP address you created with the `falco-service` service above. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the `ClusterIP`s associated with those services are routable.
Run the following commands to fill in the template file with the ClusterIP ip address you created with the `falco-service` service above, and configure audit logging to use a policy and webhook that directs the right events to the falco daemonset. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the ClusterIPs associated with those services are routable.
```
FALCO_SERVICE_CLUSTERIP=$(kubectl get service falco-service -o=jsonpath={.spec.clusterIP}) envsubst < webhook-config.yaml.in > webhook-config.yaml
minikube ssh sudo bash /tmp/k8s_audit_config/apiserver-config.patch.sh
```
### Restart the API Server to enable Audit Logging
K8s 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})`.
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
***Copying audit policy/webhook files to apiserver...
audit-policy.yaml 100% 2519 1.2MB/s 00:00
webhook-config.yaml 100% 248 362.0KB/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`.

# Kubernetes Response Engine directory moved
# Kubernetes Response Engine for Sysdig Falco
As long as Kubernetes Response Engine and Falco has different release cycles,
the Kubernetes Response Engine has been moved to its own repository.
A response engine for Falco that allows to process security events executing playbooks to respond to security threats.
You can find it in https://github.com/falcosecurity/kubernetes-response-engine
## Architecture
* *[Falco](https://sysdig.com/opensource/falco/)* monitors containers and processes to alert on unexpected behavior. This is defined through the runtime policy built from multiple rules that define what the system should and shouldn't do.
* *falco-nats* forwards the alert to a message broker service into a topic compound by `falco.<severity>.<rule_name_slugified>`.
* *[NATS](https://nats.io/)*, our message broker, delivers the alert to any subscribers to the different topics.
* *[Kubeless](https://kubeless.io/)*, a FaaS framework that runs in Kubernetes, receives the security events and executes the configured playbooks.
## Glossary
* *Security event*: Alert sent by Falco when a configured rule matches the behaviour on that host.
* *Playbook*: Each piece code executed when an alert is received to respond to that threat in an automated way, some examples include:
- sending an alert to Slack
- stop the pod killing the container
- taint the specific node where the pod is running

for the Kubernetes Response Engine running with AWS technology: SNS for messaging
and Lambda for executing the playbooks.
## Deploy
For creating the resources, just run default Makefile target:
```
make
```
This will ask for an IAM user which creates the bridge between EKS rbac and AWS IAM.
## Clean
You can clean IAM roles and SNS topics with:
```
make clean

# NATS output for Sysdig Falco
As Falco does not support a NATS output natively, we have created this small
golang utility wich reads Falco alerts from a named pipe and sends them to a
NATS server.
This utility is designed to being run in a sidecar container in the same
Pod as Falco.
## Configuration
You have a [complete Kubernetes manifest available](https://github.com/draios/falco/tree/kubernetes-response-engine/deployment/falco/falco-daemonset.yaml) for future reading.
Take a look at sidecar container and to the initContainers directive which
craetes the shared pipe between containers.
### Container image
You have this adapter available as a container image. Its name is *sysdig/falco-nats*.
### Parameters Reference
* -s: Specifies the NATS server URL where message will be published. By default
is: *nats://nats.nats-io.svc.cluster.local:4222*
* -f: Specifies the named pipe path where Falco publishes its alerts. By default
is: */var/run/falco/nats*

# SNS output for Sysdig Falco
As Falco does not support AWS SNS output natively, we have created this small
golang utility wich reads Falco alerts from a named pipe and sends them to a
SNS topic.
This utility is designed to being run in a sidecar container in the same
Pod as Falco.
## Configuration
You have a [complete Kubernetes manifest available](https://github.com/draios/falco/tree/kubernetes-response-engine/deployment/falco/falco-daemonset.yaml) for future reading.
Take a look at sidecar container and to the initContainers directive which
craetes the shared pipe between containers.
### Container image
You have this adapter available as a container image. Its name is *sysdig/falco-sns*.
### Parameters Reference
* -t: Specifies the ARN SNS topic where message will be published.
* -f: Specifies the named pipe path where Falco publishes its alerts. By default
is: */var/run/falco/nats*

# Playbooks
Following [owasp ideas](https://owaspsummit.org/Working-Sessions/Security-Playbooks/index.html),
playbooks are workflows and prescriptive instructions on how to handle specific
Security activities or incidents.
Being more specific, playbooks are actions that are going to be executed when
Falco finds a weird behavior in our Kubernetes cluster. We have implemented
them with Python and we have found that several Serverless concepts fits well
with playbooks, so we use [Kubeless](https://kubeless.io/) for its deployment.
## Requirements
* A working Kubernetes cluster
* [kubeless cli executable](https://kubeless.io/docs/quick-start/)
* Python 3.6
* pipenv
## Deploying a playbook
Deploying a playbook involves a couple of components, the function that is going
to be with Kubeless and a trigger for that function.
We have automated those steps in a generic script *deploy_playbook* who packages
the reaction and its dependencies, uploads to Kubernetes and creates the kubeless
trigger.
```
./deploy_playbook -p slack -e SLACK_WEBHOOK_URL="https://..." -t "falco.error.*" -t "falco.info.*"
```
### Parameters
* -p: The playbook to deploy, it must match with the top-level script. In this
example *slack.py* that contains the wiring between playbooks and Kubeless
functions.
* -e: Sets configuration settings for Playbook. In this case the URL where we
have to post messages. You can specify multiple *-e* flags.
* -t: Topic to susbcribe. You can specify multiple *-t* flags and a trigger
will be created for each topic, so when we receive a message in that topic,
our function will be ran. In this case, playbook will be run when a
falco.error or falco.info alert is raised.
### Kubeless 101
Under the hood, there are several useful commands for checking function state with kubeless.
We can retrieve all functions deployed in our cluster:
```
kubeless function list
```
And we can see several interesting stats about a function usage:
```
kubeless function top
```
And we can see bindings between functions and NATS topics:
```
kubeless trigger nats list
```
### Undeploying a function
You have to delete every component using kubeless cli tool.
Generally, it takes 2 steps: Remove the triggers and remove the function.
Remove the triggers:
```
kubeless trigger nats delete trigger-name
```
If you have deployed with the script, trigger-name look like:
*falco-<playbook>-trigger-<index>* where index is the index of the topic created.
Anyway, you can list all triggers and select the name.
Remove the function:
```
kubeless function delete function-name
```
If you have deployed with the script, the function name will start with *falco-<playbook>*,
but you can list all functions and select its name.
## Testing
One of the goals of the project was that playbooks were tested.
You can execute the tests with:
```
pipenv --three install -d
export KUBERNETES_LOAD_KUBE_CONFIG=1
pipenv run mamba --format=documentation
```
The first line install development tools, which includes test runner and assertions.
The second one tells Kubernetes Client to use the same configuration than kubectl and
the third one runs the test.
The tests under *specs/infrastructure* runs against a real Kubernetes cluster,
but the *spec/reactions* can be run without any kind of infrastructure.
## Available Playbooks
### Delete a Pod
This playbook kills a pod using Kubernetes API
```
./deploy_playbook -p delete -t "falco.notice.terminal_shell_in_container"
```
In this example, everytime we receive a *Terminal shell in container* alert from
Falco, that pod will be deleted.
### Send message to Slack
This playbook posts a message to Slack
```
./deploy_playbook -p slack -t "falco.error.*" -e SLACK_WEBHOOK_URL="https://..."
```
#### Parameters
* SLACK_WEBHOOK_URL: This is the webhook used for posting messages in Slack
In this example, when Falco raises an error we will be notified in Slack
### Taint a Node
This playbook taints the node which where pod is running.
```
$ ./deploy_playbook -p taint -t “falco.notice.contact_k8s_api_server_from_container”
```
#### Parameters:
* TAINT_KEY: This is the taint key. Default value: falco/alert
* TAINT_VALUE: This is the taint value. Default value: true
* TAINT_EFFECT: This is the taint effect. Default value: NoSchedule
In this example, we avoid scheduling in the node which originates the Contact
K8S API server from container. But we can use a more aggresive approach and
use -e TAINT_EFFECT=NoExecute
### Network isolate a Pod
This reaction denies all ingress/egress traffic from a Pod. It's intended to
be used with Calico or other similar projects for managing networking in
Kubernetes.
```
./deploy_playbook -p isolate -t “falco.notice.write_below_binary_dir” -t “falco.error.write_below_etc”
```
So as soon as we notice someone wrote under /bin (and additional binaries) or
/etc, we disconnect that pod. It's like a trap for our attackers.
### Create an incident in Demisto
This playbook creates an incident in Demisto
```
./deploy_playbook -p demisto -t "falco.*.*" -e DEMISTO_API_KEY=XxXxxXxxXXXx -e DEMISTO_BASE_URL=https://..."
```
#### Parameters
* DEMISTO_API_KEY: This is the API key used for authenticating against Demisto. Create one under settings -> API keys
* DEMISTO_BASE_URL: This is the base URL where your Demisto server lives on. Ensure there's no trailing slash.
* VERIFY_SSL: Verify SSL certificates for HTTPS requests. By default is enabled.
In this example, when Falco raises any kind of alert, the alert will be created in Demisto
### Start a capture using Sysdig
This playbook starts to capture information about pod using sysdig and uploads
to a s3 bucket.
```
$ ./deploy_playbook -p capture -e CAPTURE_DURATION=300 -e AWS_S3_BUCKET=s3://xxxxxxx -e AWS_ACCESS_KEY_ID=xxxxXXXxxXXxXX -e AWS_SECRET_ACCESS_KEY=xxXxXXxxxxXXX -t "falco.notice.terminal_shell_in_container"
```
#### Parameters:
* CAPTURE_DURATION: Captures data for this duration in seconds. By default is
120 seconds (2 minutes)
* AWS_S3_BUCKET: This is the bucket where data is going to be uploaded. Jobs
starts with sysdig- prefix and contain pod name and time where event starts.
* AWS_ACCESS_KEY_ID: This is the Amazon access key id.
* AWS_SECRET_ACCESS_KEY: This is the Amazon secret access key.
In this example, when we detect a shell in a container, we start to collect data
for 300 seconds. This playbook requires permissions for creating a new pod from
a Kubeless function.
### Create a container in Phantom
This playbook creates a container in Phantom
```
./deploy_playbook -p phantom -t "falco.*.*" -e PHANTOM_USER=user -e PHANTOM_PASSWORD=xxxXxxxX -e PHANTOM_BASE_URL=https://..."
```
#### Parameters
* PHANTOM_USER: This is the user used to connect to Phantom
* PHANTOM_PASSWORD: This is the password used to connect to Phantom
* PHANTOM_BASE_URL: This is the base URL where your Phantom server lives on. Ensure there's no trailing slash.
* VERIFY_SSL: Verify SSL certificates for HTTPS requests. By default is enabled.
In this example, when Falco raises any kind of alert, the alert will be created in Phantom.
## Deploying playbooks to AWS Lambda
You can deploy functions to AWS Lambda using the `./deploy_playbook_aws` script.
### Parameters
* -p: The playbook to deploy, it must match with the top-level script.
* -e: Sets configuration settings for Playbook. You can specify multiple *-e* flags.
* -k: EKS cluster name against playbook is going to connect via K8s API.
