Searching for related exceptions
An event may be a false positive, which is a legitimate operation that incorrectly
appears as an intrusion. For false positives you can create an exception and prevent
logging future identical events; however, you may have already created several
exceptions for similar events. Instead of creating a new exception, you might be able
to edit an existing exception to make it apply to the false positive event. Keeping
exceptions organized and few in number makes them easier to manage.
The
Search for Related Exceptions feature enables you to search for existing exceptions
that match one or more attributes that belong to an event. For example, you can search
for exceptions matching the event’s signature or process or both. Alternatively, you can
search for exceptions that are already deployed on the client on which the event
occurred or perhaps those applied to the user associated with the event.
To search for a related exception:
1 Select an event on the
IPS Events tab for which you want to find related exceptions,
and click
Search for Related Exceptions or the toolbar or the shortcut menu.
The
Search IPS Exception Rules search criteria dialog box appears with prefilled
process, signature, and user information.
2 Select the checkbox for each criterion you want to apply. You can edit the values by
clicking
Edit.
3 Click
OK.
The Search IPS Exceptions tab displays the results of the search. See Search IPS
Exception Rules on page 66 for more details on using this search feature.
IPS Client Rules
When clients are in Adaptive mode, client exception rules are created automatically to
allow operations that would otherwise be blocked by administrator-mandated policies.
Client rules can also be created manually, provided the Client UI policy option to allow
manual creation of client rules is enabled. Both automatic and manually-created client
rules appear on the
IPS Client Rules tab. Some or all of the client exception rules
generated on a representative client can be promoted to the general
Exception Rules tab
of a particular IPS Rules policy, allowing for ease in tuning a deployment.
