RHS429 is designed for computer security specialists and other system administrators responsible for setting and implementing security policies on a Linux computer. Applications programmers also may consider taking the course to understand how to provide a set of SELinux policies for third-party applications.Participants need not have in-depth knowledge of SELinux,but should have a basic understanding of the SELinuxsecurity layer. For example, SELinux information as taughtin RH133 or RH300 is sufficient.

•RHCE-level skills.Prerequisite skills can be shown by passing the RHCE Exam ineither RH302 or RH300, or by taking RH253 or by possessingcomparable skills and knowledge.

Among the most significant features of Red Hat EnterpriseLinux is SELinux (Security Enhanced Linux), a powerful,kernel-level security layer that provides fine-grained controlover what users and processes may access and execute on a system.By default, SELinux is enabled on Red Hat Enterprise Linuxsystems, enforcing a set of mandatory access controls that RedHat calls the targeted policy. These access controls substantiallyenhance the security of the network services they target, butcan sometimes affect the behavior of third-party applications andscripts that worked under previous versions of Red Hat EnterpriseLinux.
