Re: Re: CentOS instead of RHEL?

What you could try is looking at the STIG guides. But I'm not sure if one for CentOS even exists.

By scouring them, you would - at least from some perspective - be able to tell what changes are done to which OS to secure it, but not another.

Of course, it's by no means complete, but it may give you a start.
