Exclude specific network activity from being
monitored
In some cases, benign network activity may appear
similar to an attack signature. If you receive repeated
warnings about possible attacks, and you know that
these warnings are being triggered by safe behavior, you
can create an exclusion for the attack signature that
matches the benign activity.

Each exclusion that you create leaves your computer
vulnerable to attacks. Be very selective when excluding
attacks. Only exclude behavior that is always benign.
