RE: Waiver support in HTML report

[Chen, Wei (Contractor)(CFPB)]

I think there should be an option to track the score even if a rule is waived.  The score is a representation of risk, waiving the rule doesn't mean the risk disappeared but simply accepted.  The amount of risk being accepted should be made available to the authorizing official or system owner.  Also, a field for how long the waiver is valid for will be beneficial since permanent waivers are frowned upon in general.

Regards,
Wei

Replied about this to Shawn.

It does not. For all intents and purposes it behaves like a rule of the result
the waiver set it to. So if you waive a failed rule and make it "pass" you
basically make it behave exactly like a passed rule.

Waiver support in HTML report

[Trevor Vaughan]

What about the case where rule waiving is done just because the rule
doesn't apply?

Also, is there the ability to modify the scoring system? For instance, the
NIST 800-53 (I think), specifies that risk levels can be decreased by
surrounding details. Extra Firewalls, ALS systems, increased monitoring,
etc...

Therefore, the risk for any externally facing items could be decreased from
High to Medium or Medium to Low, etc...

Sorry if I missed this, I'm still trying to find time to turn all the knobs
but, great work and thanks for the materials!
