RHS429 Red Hat Enterprise SELinux Policy Administration

Course Description

Security-enhanced Linux (SELinux) is a powerful, kernel-level security layer that provides fine-grained control over which users and processes may access what resources and execute which programs on a system. Red Hat Enterprise SELinux Policy Administration (RHS429) introduces senior system administrators, security administrators, and application programmers to SELinux policy writing. Students will learn how SELinux works, how to manage, and how to write, compile and debug a SELinux policy. This class culminates in a major project to analyze, determine the security needs, design and implement a set of net new policies for a service previously unprotected by SELinux.
