Existing System Migration

If you are looking to use the SIMP materials on an existing system, instructions are available in the SIMP Documentation.

New System/Bare Metal

If you're using a new system, such as a fresh VM or a bare metal system, you will want to follow the instructions for building an ISO.

User Documentation

Product documentation is housed at ReadTheDocs.org.

Where's the code?!

For those out there that just want the goods, the actual code for the SIMP project is hosted under the SIMP GitHub Organization.


SIMP is a framework that provides a flexible combination of security compliance and operational automation.

The goal of the project is to provide a complete management environment focused on compliance with the various profiles in the SCAP Security Guide and industry best practice.

Though it is fully capable out of the box, the intent of SIMP is to be molded to your target environment in such a way that deviations are easily identifiable to both Operations Teams and Security Officers.

At this time, there are no commercial requirements for the use of SIMP outside of the purchase of Red Hat Enterprise Linux licenses as applicable.
