Audit rule exceptions

For most audit rules, you can create temporary or permanent rule exceptions on selected target servers (or groups of servers) in the audit. This means you can exclude specific rules on selected targets of the audit when the audit runs.

For example, in an audit that is auditing several servers, you might want to suspend one or more of the rules for a subset of the servers targeted by the audit. You might have a collection of Windows servers that are regularly audited to make sure that the IIS service is disabled, for example, to meet company security standards. Your audit is configured to check each of those servers to make sure IIS is disabled. If IIS is enabled on any of the servers, the audit will fail.

However, for a short period of time you might want to run a business application that requires the IIS service to be enabled in order to run on a few of the servers targeted in the audit. You can create a rule exception for the rule governing the IIS service and associate the exception with the servers that need to run the application. This ensures that the audit can still run and not fail when it encounters the servers that do have the IIS service enabled.

You can set an expiration date for the rule exceptions to make sure that when the rule exception is no longer needed or permitted, the rule will be applied to all servers in the audit. You can also write a reason for the exception and associate a ticket ID with it. Exceptions you create in one audit do not affect rules in any other audits.

Rules that cannot have exceptions

Most audit rules can have exceptions created for them. However, rule categories that include ALL of a set of rules cannot have exceptions.

Considerations when applying exceptions to device groups

When you set an audit rule exception for a device group, the exception will be applied to all servers in the group. It is possible that one of the servers in the group with the exception also belongs to another device group, which also happens to be the target of an audit that has no exceptions applied to it.

In this situation, the rule exception always applies to the server, even though the server also belongs to a device group with no exceptions. As a rule of thumb, keep in mind any servers in a device group that has a rule exception applied to it will have the audit rule excepted, whether or not the server belongs to another device group that is targeted by an audit and has the same rule applied without an exception.
