The new mapping is now in the list.
3. Setup email server and enable alerting, System->Logging:
Check Enable E-mail alerting for IDS/IDP events
Select sensitivity Normal
Enter SMTP server IP (email server): 192.168.2.4
Enter sender: idsalert@examplecompany.com
Enter E-mail address 1: webmaster@examplecompany.com
Enter E-mail address 2: steve@examplecompany.com
Click Apply
4. Click Activate and wait for the firewall to restart.
When attacks are stopped by the firewall it will listed in the logs. Since we enabled email
alerting in this example, emails will also be sent to the users webmaster and steve.
To get more information about the attack, copy the attack string and paste it into the By
message box at the following address: http://www.snort.org/cgi-bin/sigs-search.cgi
(you can
of course also write the attack string manually in the box).
In this example we used the prevention mode. This means that the firewall will block all
attacks. In Inspection only mode nothing will be blocked, the firewall will only log the attacks
and send email alerts (if that is enabled).
