Override regular expression limits for intrusion rules

Override the default regular expression limits to customize performance settings for intrusion rules according to your network requirements.

Regular expression limits control the processing of pattern matching in intrusion rules. Modifying these limits can help optimize performance based on your specific environment and traffic patterns.

Procedure

Step 1

In the access control policy editor, click Advanced.

In the new UI, select Advanced Settings from the drop-down arrow at the end of the packet flow line.

Step 2

Click Edit (edit icon) next to Performance Settings.

If View (View button) appears instead, settings are inherited from an ancestor policy, or you do not have permission to modify the settings. If the configuration is unlocked, uncheck Inherit from base policy to enable editing.

Step 3

Click Regular Expression Limits in the Performance Settings pop-up window.

Step 4

You can modify any of the options as described in Regular expression limits overrides for intrusion rules.

Step 5

Click OK.

Step 6

Click Save to save the policy.
