Instructor:

This two-part, hands-on course attempts to break down some of the barriers to SELinux adoption in your organization.

Part One focuses on a high-speed introduction to SELinux and a troubleshooting strategy to help you diagnose and correct issues due to SELinux. Part Two gets into the guts of SELinux and provides guidance on developing SELinux policies for new services.

In most organizations, the only thought given to SELinux is remembering to turn it off when installing new systems. And yet as I respond to intrusion after intrusion on Linux systems, I know that most of them would never have happened had SELinux been properly deployed.

SELinux has been hampered by a suspicious pedigree (“It comes from the NSA—fear it!”) and a horrible initial roll-out (“This breaks everything—kill it with fire!”). But largely the issue is that the SELinux universe stands outside the normal Linux security model and troubleshooting strategy. Things break in mysterious ways when you enable SELinux, and the fixes are not obvious.

Key Takeaways

Students will learn basic commands for interacting with the SELinux universe as well as how to:

  • Troubleshoot system issues where SELinux is enabled
  • Correct issues so your applications can work safely with SELinux
  • Extend the default SELinux policy to work with new applications
