Go to the IPS Global Settings section of the Security Services > Intrusion Prevention page.

CAUTION: Leaving the High Priority Attacks, Medium Priority Attacks, and Low Priority Attacks signature groups with no Prevent All action checked means no intrusion prevention will occur on the SonicWall security appliance.

For each class of attack in the Signature Groups table, select the Detect All checkboxes. Attacks belonging to the enabled group will be logged.
4
Optionally, specify the number of seconds to delay between log entries for the same detected attack in its Log Redundancy Filter (seconds) field. The default for High Priority Attacks and Medium Priority Attacks is 0 seconds (every attack is logged) and for Low Priority Attack is 60 seconds.
