IntruGuard's solutions protect traffic at the ingress point of the attack from DDoS floods, and from protocol anomaly attacks, port, network and dark address scans, and other unwarranted traffic based assaults. The network IPS market is composed of in-line devices that perform full-stream assembly of network traffic, and provide protection using several methods including signatures, protocol anomaly detection, and behavioral or heuristics. Other additions to the Firebox[R] X Edge also include scalable transparent proxies that provide application-layer inspection, heading off otherwise unknown threats through advanced protocol anomaly detection and pattern matching. |
