NetScreen uses multi-method detection (MMD) in its IDS appliance, which also includes intrusion prevention options. MMD integrates stateful signature analysis with the detection of protocol anomalies, traffic anomalies, IP spoofing, layer 2 and SYN-flood attacks. Plus, it includes detection of 'backdoor' exploits and a network honeypot. The NetScreen IDP-100 is rated at 200Mbits/sec throughput, offering a choice of eight Fast Ethernet or two separate gigabit monitoring ports.
