filter.

Alerting is a standard component of most intrusion detection systems because
security analysts must be kept informed of attack activity without having to
constantly monitor the Network Security console. Unfortunately, many IDS
products use the same interface for detection as for notification. In such a
configuration, a flood attack could prevent the console from sending email
notifications because the flood attack would overload the interface.
Symantec Network Security uses a separate, independent interface for
notification, thus enabling the Network Security console to successfully send
email notification even during an attack.
