GS108T and GS110TP Smart Switch Software Administration Manual Denial of Service Use the Denial of Service (DoS) page to configure DoS control. The GS108T and GS110TP software provides support for classifying and blocking specific types of DoS attacks. You can configure your system to monitor and block six types of attacks: • SIP=DIP: Source IP address = Destination IP address. • First Fragment: TCP Header size is smaller than the configured value. • TCP Fragment: IP Fragment Offset = 1. • TCP Flag: TCP Flag SYN set and Source Port < 1024 or TCP Control Flags = 0 and TCP Sequence Number = 0 or TCP Flags FIN, URG, and PSH set and TCP Sequence Number = 0 or TCP Flags SYN and FIN set. • L4 Port: Source TCP/UDP Port = Destination TCP/UDP Port. • ICMP: Limiting the size of ICMP Ping packets. Auto-DoS Configuration The Auto-DoS Configuration page lets you automatically enable all the DoS features available on the switch, except for the L4 Port attack. See the previous section for information about the types of DoS attacks the switch can monitor and block.
