MULTI-METHOD GATEWAY-BASED NETWORK SECURITY SYSTEMS

摘要

Systems and methods for detecting and preventing network security breaches (23) are described. The systems and methods present a gateway-based packet-forwarding network security solution to not only detect security breaches but also prevent from by directly dropping suspicious packets and connections. The systems and methods employ multiple techniques to detect and prevent network security breaches (30), including stateful signature detection, traffic signature detection, and protocol anomaly detection (35).
