Security-Enhanced Linux Reference Policy

  The SELinux Reference Policy project (refpolicy) is a complete SELinux policy
  that can be used as the system policy for a variety of systems and used as the
  basis for creating other policies. Reference Policy was originally based on
  the NSA example policy, but aims to accomplish many additional goals:
    + Strong Modularity
    + Security Goals
    + Documentation
    + Development Tool Support
    + Forward Looking
    + Configurability
    + Flexible Base Policy
    + Application Policy Variations
    + Multi-Level Security
