Modifying the Protection Action of an Intrusion Prevention Rule
For rules in the basic defense rule library and the virtual patch rule library, you can manually modify their protection actions. After the modification, their actions do not change with the IPS protection mode.
If the rules in the rule library cannot meet your requirements, you can customize IPS signature rules. For details, see Customizing IPS Signatures.
Constraints
- The action of a manually modified rule remains unchanged even if Protection Mode is changed.
- The constraints on manually modified actions are as follows:
- The actions of up to 3000 rules can be manually changed to observation.
- The actions of up to 3000 rules can be manually changed to interception.
- The actions of up to 128 rules can be manually changed to disabling.
