Chapter 21      Managing Rules in an Intrusion Policy
  Filtering Rules in an Intrusion Policy
Understanding Rule Configuration Filters
License: 
Protection
You can filter the rules listed in the Rules page by several rule configuration settings. For example, if 
you want to view the set of rules whose rule state does not match the recommended rule state, you can 
filter on rule state by selecting 
Does not match recommendation
.
When you select a keyword by clicking on a node in the criteria list, a pop-up window appears, where 
you supply the argument you want to filter by. 
If that keyword is already used in the filter, the argument you supply replaces the existing argument for 
that keyword. 
For example, if you click 
Drop and Generate Events
 under 
Rule Configuration > Recommendation
 in the filter 
panel, 
Recommendation:"Drop and Generate Events"
 is added to the filter text box. If you then click 
Generate Events 
under 
Rule Configuration > Recommendation
, the filter changes to 
Recommendation:"Generate Events"
.
See the following procedures for more information on the rule configuration settings you can use to 
filter.
To use the Rule State filter:
Access:

Priority
Finds rules according to high, medium, and 
low priorities.
The classification assigned to a rule determines 
its priority. These groups are further grouped 
into rule categories. Note that local rules (that 
is, rules that you create) do not appear in the 
priority groups.

specific rule update. For each rule update, view
