Intrusion Detection and Prevention System

Executive SummaryDeep packet inspection (DPI) filters computer network packets and examines the data in a packet, performing searches for viruses, spam, or other intrusions. DPI can be implemented on routers, network intrusion detection systems, firewalls and switches but detecting multiple patterns in parallel requires a significant amount of memory...

A High-Speed Grammar Aware Application Protocol Parsing Algorithm for Networking and Security Devices

IntroductionThere is an increasing desire to create content aware networks that can improve data delivery by classifying and controlling messages based on content, application, and individual subscribers. There is also a need to improve network security via content-based monitoring and filtering. Building content aware networks requires both advanced...

A Systematic Approach to Minimizing Packet Classifiers in TCAMs

IntroductionPacket classification enables many networking services on the Internet, such as firewall packet filtering and traffic accounting. Using Ternary Content Addressable Memory (TCAM) chips to perform high-speed packet classification has become the de facto standard in industry. TCAM chips classify packets by comparing a packet with the full suite...
