We are making progress. Still waiting to hear back on a couple of issues, but progress is being made.
For others that may not know of the effort that Shawn eluded to.. I work closely with DISA in my role at Red Hat. We have a goal to eventually, align the SSG and STIG content. The benefit of everyone is that if you use SSG to do something like lock down the OS while it is being provisioned, or to periodically scan a system from Satellite server, the results of those scan will be identical to a scan using ACAS. The end result is a security posture that is much easier to maintain and a great chance that any configuration drift will not occur.
