Override settings in the global Snort configuration for individual Engines

You can optionally import a Snort configuration .zip file for an individual Engine to override settings in the global Snort configuration for specific Engines.

All Engines for which Snort inspection is enabled use the global Snort configuration by default. If you do not want to override settings in the global Snort configuration, it is not necessary to import a Snort configuration file for an individual Engine.

Settings in the Snort configuration .zip file for an individual Engine are combined with the settings in the global Snort configuration .zip file. If any configuration files in a Snort configuration .zip file for an individual Engine have the same files name and paths as configuration files in the global Snort configuration .zip file, the overlapping files in the global Snort configuration .zip file are ignored.
Note: Engines do not receive automatic updates for Snort rule sets. When new Snort rule sets are available, you must import new Snort configuration files and refresh the policy on the Engine to start using the new Snort rule sets.
