Next Generation Intrusion Prevention System

The network intrusion prevention system (IPS) appliance solution is composed of stand-alone appliances that inspects all network traffic that has passed through frontline security devices, such as firewalls, Web security gateways and email security gateways. IPS devices are deployed in line and perform full stream reassembly of network traffic. They provide detection via several methods — signatures, protocol anomaly detection, behavioral or heuristics. By being in-line, IPSs can also use various techniques to block attacks that are identified with high confidence.
