Description:

Security-enhanced Linux is a patch of the Linux kernel and a number
of utilities with enhanced security functionality designed to add
mandatory access controls to Linux. The Security-enhanced Linux kernel
contains new architectural components originally developed to improve
the security of the Flask operating system. These architectural
components provide general support for the enforcement of many kinds
of mandatory access control policies, including those based on the
concepts of Type Enforcement, Role-based Access Control, and
Multi-level Security.

policycoreutils contains the policy core utilities that are required
for basic operation of a SELinux system. These utilities include
load_policy to load policies, setfiles to label filesystems, newrole
to switch roles, and run_init to run /etc/init.d scripts in the proper
context.
