Add test that cover reading from multiple sets of rule files and
disabling rules. Specific changes:
- Modify falco to allow multiple -r arguments to read from multiple
files.
- In the test multiplex file, add a disabled_rules attribute,
containing a sequence of rules to disable. Result in -D arguments
when running falco.
- In the test multiplex file, 'rules_file' can be a sequence. It
results in multiple -r arguments when running falco.
- In the test multiplex file, 'detect_level' can be a squence of
multiple severity levels. All levels will be checked for in the
output.
- Move all test rules files to a rules subdirectory and all trace files
to a traces subdirectory.
- Add a small trace file for a simple cat of /dev/null. Used by the
new tests.
- Add the following new tests:
- Reading from multiple files, with the first file being
empty. Ensure that the rules from the second file are properly
loaded.
- Reading from multiple files with the last being empty. Ensures
that the empty file doesn't overwrite anything from the first
file.
- Reading from multiple files with varying severity levels for each
rule. Ensures that both files are properly read.
- Disabling rules from a rules file, both with full rule names
and regexes. Will result in not detecting anything.

Sysdig Falco
####Latest release
v0.3.0 Read the change log
Dev Branch: 
Master Branch: 
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 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

License Terms

Contributor License Agreements
###Background As we did for sysdig, 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). 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 we’ve tried to make this process as clear and simple as possible.
We’ve modeled our CLA off of industry standards, such as the CLA used by Kubernetes. 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:
- Django’s excellent CLA FAQ
- A well-written chapter from Karl Fogel’s Producing Open Source Software on CLAs
- The Wikipedia article on CLAs
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 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, 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:
falco-CLA-1.0-contributing-entity: Full Legal Name of Entity
