osquery is an operating system instrumentation framework for OSX and Linux. osquery makes low-level operating system analytics and monitoring both performant and intuitive.

osquery exposes an operating system as a high-performance relational database. This allows you to write SQL-based queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as

• running processes
• loaded kernel modules
• open network connections

SQL tables are implemented via an easily extendable API. A variety of tables already exist and more are being written.

To best understand the expressiveness that is afforded to you by osquery, consider the following SQL queries:

--------------------------------------------------------
-- get the name, pid and attached port of all processes
-- which are listening on all interfaces
--------------------------------------------------------
SELECT DISTINCT
  process.name,
  listening.port,
  process.pid
FROM processes AS process
JOIN listening_ports AS listening
ON process.pid = listening.pid
WHERE listening.address = '0.0.0.0';

--------------------------------------------------------
-- find every launchdaemon on an OS X host which
--   * launches an executable when the operating
--     system starts
--   * keeps the executable running
-- return the name of the launchdaemon and the full
-- path (with arguments) of the executable to be ran.
--------------------------------------------------------
SELECT
  name,
  program || program_arguments AS executable
FROM launchd
WHERE
  (run_at_load = 'true' AND keep_alive = 'true')
AND
  (program != '' OR program_arguments != '');

These queries can be:

• performed on an ad-hoc basis to explore operating system state
• executed via a scheduler to monitor operating system state across a distributed set of hosts over time
• launched from custom applications using osquery APIs

Install

OS X

The easiest way to install osquery on OS X is via Homebrew. Check the Homebrew homepage for installation instructions.

Run the following:

brew update
brew install osquery

To update osquery:

brew update
brew upgrade osquery

Linux

We don't currently supply pre-built osquery packages for Linux. We do, however, provide Vagrant VMs which allow you to easily create packages for Ubuntu 12.04+ and CentOS 6.5. Check out the wiki's installation guide for more information.

If you're trying to build osquery on a different, currently unsupported operating system, please refer to the building the code guide for help.

Vulnerabilities

Facebook has a bug bounty program which osquery participates in. If you find a vulnerability in osquery, please submit it via the process outlined on that page and do not file a public issue.

For more information on finding vulnerabilities in osquery, see a recent blog post about bug-hunting osquery: https://www.facebook.com/notes/facebook-bug-bounty/bug-hunting-osquery/954850014529225
