The Example Corporation has a web site that is the target of SYN floods. While they investigate the source of the attacks, it’s very important that the web site remain accessible. To enhance the ability of the company’s FortiGate-620B to deal with SYN floods, the administrator will install an ASM-CE4 Fortinet Security Processing module and have all external access to the web server come though it.

The security processing modules not only accelerate and offload network traffic from the FortiGate unit’s processor, but they also accelerate and offload security and content scanning. The ability of the security module to accelerate IPS scanning and DoS protection greatly enhances the defense capabilities of the FortiGate-620B.
