Policy module

A policy module will define your application rules. It is easy to install and uninstall.

It contains three files :

  • type enforcement (.te): contains the rules to confine your application.
  • file context (.fc): defines which label to give to each file.
  • interfaces (.if): contains interfaces to say how applications interact with the modules


To compile a SELinux module, we place our different files in a folder. The output is a policy package (.pp) file.

Package requirement: selinux-policy-dev for Debian, selinux-policy-devel for RHEL

make -f /usr/share/selinux/devel/Makefile -C /usr/share/sec-lsm-manager/selinux-rules demo-app.pp

Install / Uninstall

To install the newly created SELinux module, use the following command :

semodule -i demo-app.pp

And to remove it :

semodule -r demo-app.pp
