It seems the client does not read/display/or even recognize the <refine-value xccdf statement. At least I don't see it on the interface and can't seem to change it. I've been using the standard NIST FDCC XP benchmark which is full of these statements and editing the rules and variables doesn't seem to display or take these into account. Am I missing something?
If i'm right, I believe your referring to the refine-values statements that define the tailored values in the FDCC profile. If you go to List: Profiles, you can create your own profile, or open the included FDCC-defined profile. The profiles interface includes a Refine Values tab that allows you to tailor values based on what you defined in the rule/check values.
