Types of waivers
Policy Auditor provides three types of waivers that apply to a system being audited. Each type
of waiver has different effects on scoring results.
Exception waivers
Exception waivers force the result of a benchmark rule to be Pass, thus potentially altering the
benchmark score of a system. They have the following characteristics:
Each waiver applies only to a single managed system. Exception waivers require you to
select a benchmark and a rule contained in the benchmark that will not apply to an audit of
the system.
The selected benchmark and rule is included in an audit of the system, but the audit result
of the particular rule is always Pass.
Only benchmarks that are Active can be specified in the waiver.
Exception waivers can be backdated. Scores for any results collected during the backdate
time frame are recalculated.
Rules used in an exception waiver appear in the audit results.
Example of scoring impact:
A benchmark has 5 rules. An audit is run and 4 rules pass and 1 fail, resulting in a score of
80%. If the rule that failed is granted an exception, then all 4 rules pass and the score is
100%.
Exemption waivers
Exemption waivers are system-based and prevent a system from being audited. When you
request an Exemption waiver, Policy Auditor does not allow you to assign a benchmark and
rule. They have the following characteristics:
Each waiver applies only to a single managed system. Exemption waivers do not require
you to select a benchmark and a rule for the system.
A system is not audited while the waiver is in effect.
An exemption waiver can be created at any time for an existing system.
An exemption waiver cannot be backdated.
A system affected by an exemption waiver will not appear in the audit results.
