Intrusion Detection

The Barricade’s firewall inspects packets at the application layer, maintains 
TCP and UDP session information including timeouts and number of 
active sessions, and provides the ability to detect and prevent certain types 
of network attacks such as Denial-of-Service (DoS) attacks.
