DIACAP vs DIARMF & STIGs & CCEs.

" A profile is just statement about a set of controls: a collection of controls plus variable settings."

That brings up another important point regarding the controls.  How would one configure the organizational defined values and feed it to the benchmark?  Obviously, if the profiles are meant to be generic, the values can't be hardcoded in the OVAL file.  You can setup the benchmark like USGCB content that allows default values to be overridden with external variables, but it is not as straight forward as one would like.  Perhaps another shorthand XML that takes in organizational values or simply rebuild the SSG content with custom values?

Regards,
Wei

Trevor makes an interesting point. 

Representing a specific security policy is just one use case for a "profile".

A profile is just statement about a set of controls: a collection of controls plus variable settings. 

A profile explicitly about audit rules, for example, could be a useful training tool. Another profile focused on services or libraries, could be useful gathering an adhoc inventory across many systems.

The set of controls may be different based on the control selection and tailoring process that each system has to go through.  Not to mention no single SCAP benchmark can encompass all of the minimum required controls from the different control families.
