18 How to configure the AT-AR450S Firewall using the Graphical User Interface (GUI)
C613-16011-00 REV A
13 February 2004
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.
