This file documents all notable changes to Falco. The release numbering uses [semantic versioning](http://semver.org).
## v0.14.0
Released 2019-02-06
## Major Changes
* Rules versioning support: The falco engine and executable now have an *engine version* that represents the fields they support. Similarly, rules files have an optional *required_engine_version: NNN* object that names the minimum engine version required to read that rules file. Any time the engine adds new fields, event sources, etc, the engine version will be incremented, and any time a rules file starts using new fields, event sources, etc, the required engine version will be incremented. [[#492](https://github.com/falcosecurity/falco/pull/492)]
* Allow SSL for K8s audit endpoint/embedded webserver [[#471](https://github.com/falcosecurity/falco/pull/471)]
* Add stale issues bot that automatically flags old github issues as stale after 60 days of inactivity and closes issues after 67 days of inactivity. [[#500](https://github.com/falcosecurity/falco/pull/500)]
* Support bundle: When run with `--support`, falco will print a json object containing necessary information like falco version, command line, operating system information, and falco rules files contents. This could be useful when reporting issues. [[#517](https://github.com/falcosecurity/falco/pull/517)]
## Minor Changes
* Support new third-party library dependencies from open source sysdig. [[#498](https://github.com/falcosecurity/falco/pull/498)]
* Add CII best practices badge. [[#499](https://github.com/falcosecurity/falco/pull/499)]
* Fix kernel module builds when running on centos as a container by installing gcc 5 by hand instead of directly from debian/unstable. [[#501](https://github.com/falcosecurity/falco/pull/501)]
* Mount `/etc` when running as a container, which allows container to build kernel module/ebpf program on COS/Minikube. [[#475](https://github.com/falcosecurity/falco/pull/475)]
* Improved way to specify the source of generic event objects [[#480](https://github.com/falcosecurity/falco/pull/480)]
* Readability/clarity improvements to K8s Audit/K8s Daemonset READMEs. [[#503](https://github.com/falcosecurity/falco/pull/503)]
* Add additional RBAC permissions to track deployments/daemonsets/replicasets. [[#514](https://github.com/falcosecurity/falco/pull/514)]
## Bug Fixes
* Fix formatting of nodejs examples README [[#502](https://github.com/falcosecurity/falco/pull/502)]
## Rule Changes
* Remove FPs for `Launch Sensitive Mount Container` rule [[#509](https://github.com/falcosecurity/falco/pull/509/files)]
* Update Container rules/macros to use the more reliable `container.image.{repository,tag}` that always return the repository/tag of an image instead of `container.image`, which may not for some docker daemon versions. [[#513](https://github.com/falcosecurity/falco/pull/513)]
## v0.13.1
Released 2019-01-16
## Major Changes
## Minor Changes
* Unbuffer outputs by default. This helps make output readable when used in environments like K8s. [[#494](https://github.com/falcosecurity/falco/pull/494)]
* Improved documentation for running Falco within K8s and getting K8s Audit Logging to work with Minikube and Falco as a Daemonset within K8s. [[#496](https://github.com/falcosecurity/falco/pull/496)]
* Fix AWS Permissions for Kubernetes Response Engine [[#465](https://github.com/falcosecurity/falco/pull/465)]
* Tighten compilation flags to include `-Wextra` and `-Werror` [[#479](https://github.com/falcosecurity/falco/pull/479)]
* Add `k8s.ns.name` to outputs when `-pk` argument is used [[#472](https://github.com/falcosecurity/falco/pull/472)]
* Remove kubernetes-response-engine from system:masters [[#488](https://github.com/falcosecurity/falco/pull/488)]
## Bug Fixes
* Ensure `-pc`/`-pk` only apply to syscall rules and not k8s_audit rules [[#495](https://github.com/falcosecurity/falco/pull/495)]
* Fix a potential crash that could occur when using the falco engine and rulesets [[#468](https://github.com/falcosecurity/falco/pull/468)]
* Fix a regression where format output options were mistakenly removed [[#485](https://github.com/falcosecurity/falco/pull/485)]
## Rule Changes
* Fix FPs related to calico and writing files below etc [[#481](https://github.com/falcosecurity/falco/pull/481)]
* Fix FPs related to `apt-config`/`apt-cache`, `apk` [[#490](https://github.com/falcosecurity/falco/pull/490)]
* New rules `Launch Package Management Process in Container`, `Netcat Remote Code Execution in Container`, `Lauch Suspicious Network Tool in Container` look for host-level network tools like `netcat`, package management tools like `apt-get`, or network tool binaries being run in a container. [[#490](https://github.com/falcosecurity/falco/pull/490)]
* Fix the `inbound` and `outbound` macros so they work with sendto/recvfrom/sendmsg/recvmsg. [[#470](https://github.com/falcosecurity/falco/pull/470)]
* Fix FPs related to prometheus/openshift writing config below /etc. [[#470](https://github.com/falcosecurity/falco/pull/470)]
## v0.13.0
Released 2018-11-09
## Major Changes
* **Support for K8s Audit Events** : Falco now supports [K8s Audit Events](https://kubernetes.io/docs/tasks/debug-application-cluster/audit/#audit-backends) as a second stream of events in addition to syscalls. For full details on the feature, see the [wiki](https://github.com/falcosecurity/falco/wiki/K8s-Audit-Event-Support).
* Transparent Config/Rule Reloading: On SIGHUP, Falco will now reload all config files/rules files and start processing new events. Allows rules changes without having to restart falco [[#457](https://github.com/falcosecurity/falco/pull/457)] [[#432](https://github.com/falcosecurity/falco/issues/432)]
## Minor Changes
* The reference integration of falco into a action engine now supports aws actions like lambda, etc. [[#460](https://github.com/falcosecurity/falco/pull/460)]
* Add netcat to falco docker images, which allows easier integration of program outputs to external servers [[#456](https://github.com/falcosecurity/falco/pull/456)] [[#433](https://github.com/falcosecurity/falco/issues/433)]
## Bug Fixes
* Links cleanup related to the draios/falco -> falcosecurity/falco move [[#447](https://github.com/falcosecurity/falco/pull/447)]
* Properly load/unload kernel module when the falco service is started/stopped [[#459](https://github.com/falcosecurity/falco/pull/459)] [[#418](https://github.com/falcosecurity/falco/issues/418)]
## Rule Changes
* Better coverage (e.g. reduced FPs) for critical stack, hids systems, ufw, cloud-init, etc. [[#445](https://github.com/falcosecurity/falco/pull/445)]
* New rules `Launch Package Management Process in Container`, `Netcat Remote Code Execution in Container`, and `Lauch Suspicious Network Tool in Container` look for running various suspicious programs in a container. [[#461](https://github.com/falcosecurity/falco/pull/461)]
* Misc changes to address false positives in GKE, Istio, etc. [[#455](https://github.com/falcosecurity/falco/pull/455)] [[#439](https://github.com/falcosecurity/falco/issues/439)]

# 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.

## 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, you can easily detect things like:

# Introduction
The files in this directory can be used to configure k8s audit logging. The relevant files are:
* [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.
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.
* [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.
A way to use these files with minikube to run falco and enable audit logging would be the following:
#### Start Minikube with Audit Logging Enabled
Run the following to start minikube with Audit Logging Enabled:
```
minikube start --kubernetes-version v1.11.0 --mount --mount-string $PWD:/tmp/k8s_audit_config --feature-gates AdvancedAuditing=true
```
#### Create a Falco DaemonSet and Supporting Accounts/Services
Follow the [K8s Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a falco service account, service, configmap, and daemonset.
#### Configure Audit Logging with a Policy and Webhook
Run the following commands to fill in the template file with the ClusterIP ip address you created with the `falco-service` service above, and configure audit logging to use a policy and webhook that directs the right events to the falco daemonset. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the ClusterIPs associated with those services are routable.
```
FALCO_SERVICE_CLUSTERIP=$(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
```
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})`.

In this directory are the Terraform manifests for creating required infrasturcture
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
```

# 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*
