49.7.2. Where is the Policy?

download PDF
There are two components to the policy: the binary tree and the source tree. The binary tree is provided by the selinux-policy-<policyname> package and supplies the binary policy file.
Alternatively, the binary policy can be built from source when the selinux-policy-devel package is installed.


Information on how to edit, write and compile policy is currently outside the scope of this document. Binary Tree Files

  • /etc/selinux/targeted/ — this is the root directory for the targeted policy, and contains the binary tree.
  • /etc/selinux/targeted/policy/ — this is the location of the binary policy file policy.<xx>. In this guide, the variable SELINUX_POLICY is used for this directory.
  • /etc/selinux/targeted/contexts/ — this is the location of the security context information and configuration files, which are used during runtime by various applications.
  • /etc/selinux/targeted/contexts/files/ — contains the default contexts for the entire file system. This is referenced by restorecon when performing relabeling operations.
  • /etc/selinux/targeted/contexts/users/ — in the targeted policy, only the root file is in this directory. These files are used for determining context when a user logs in. For example, for the root user, the context is user_u:system_r:unconfined_t.
  • /etc/selinux/targeted/modules/active/booleans* — this is where the runtime Booleans are configured.


    These files should never be manually changed. You should use the getsebool, setsebool and semanage tools to manipulate runtime Booleans.
