Alarms tab

The Alarms tab allows you to set the thresholds at which the firewall module will decide

that certain types of attack are underway. You are also able to provide an email address to

which the firewall will send alarm messages every time any attack is detected. Most

attacks consist of a stream of packets that follow a certain pattern.

The threshold is set by specifying how many packets consistent with a certain attack type

need to be received within a certain period before the firewall module will decide that an

attack is occurring.

You can find descriptions and default settings for each type of attack in the GUI

help.

You should not change the Alarm Thresholds unless the current

thresholds are not working for your network. Contact your nearest

authorised Allied Telesyn reseller or distributor for more information

and help regarding these thresholds.
