I cannot locate this guide. I have redhat scap-security-guide 0.10.21-3.el6 which yum says is the latest.

I think the profile for National Security Systems Instruction (CNSSI) No. 1253, "Security Categorization and Control Selection for National Security Systems""

How can I get this? rpm preferred

Thanks.
