This is not a full solution. It only implements part of the STIG process and therefore still requires a script to be run on a host-by-host basis. If they were serious about supporting a huge customer in the DoD they would release the full STIG process via a VIB and make it signed at partner or above. Afterall, it clearly states in the STIG Guide that it’s a CAT 1 finding if it’s a community signed VIB.
Until this happens, this is really of no use.
The alternative would be to make an authoring software readily available for multiple platforms which allows the DoD signature and then DISA changes the STIG requirements.
