Set Connection Rate Limits
To improve network security, you can create a limit on a policy so that it only filters a specified number of connections per second. If additional connections are attempted, the traffic is denied and a log message is generated.
You can also configure the policy to generate an alarm when the connection rate limit is exceeded. You can configure the alarm to make the Firebox send an event notification to the SNMP management system, or to send a notification as an email message or a pop-up window on the management computer.
