Chapter 14 Firewall Configuration 185

14.4.3 Alerts

Alerts are reports on events, such as attacks, that you may want to know about right away. You

can choose to generate an alert when an attack is detected in the Edit Rule screen (select the

Send Alert Message to Administrator When Matched check box) or when a rule is matched

in the Edit Rule screen (see Section 14.6.1 on page 188).

When an event generates an alert, a

message can be immediately sent to an e-mail account that you specify in the Log Settings

screen (see the chapter on logs).

directly to a LAN computer without passing through the

route topology and how to deal with this problem.
