Modifying Existing Rules

You can save system-provided rules and rules belonging to ancestor domains as new custom rules in the local rule category, which you can then modify.

Procedure

Step 1

Access the intrusion rules using either of the following methods:

Choose Policies > Access Control heading > Intrusion.
Click Snort 2 Version next to the policy you want to edit and click Rules.
Choose Objects > Intrusion Rules.

Step 2

Locate the rule you want to modify. You have the following choices:

Step 3

Click Edit ( edit icon ) next to the rule or, in the case of search results, click the rule message.

If View ( View button ) appears instead, the configuration belongs to an ancestor domain, or you do not have permission to modify the configuration.

Step 4

Modify the rule as appropriate for the rule type.

Note	Do not modify the protocol for a shared object rule; doing so would render the rule ineffective.

Step 5

You have the following choices:

Click Save if you are editing a custom rule and want to overwrite the current version of that rule.
Click Save As New if you are editing a system-provided rule or any rule belonging to an ancestor domain, or if you are editing a custom rule and want to save the changes as a new rule.

If you want to use the local modification of the rule instead of the system-provided rule, deactivate the system-provided rule by using the procedures at Intrusion Rule States and activate the local rule.
Deploy configuration changes.
