SELinux policy compiler
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. . This package contains checkpolicy, the SELinux policy compiler. Only required for building policies. It uses libsepol to generate the binary policy. checkpolicy uses the static libsepol since it deals with low level details of the policy that have not been encapsulated/abstracted by a proper shared library interface.
