Scalability of Hash-Based Pattern Matching for High-Speed Network Security and Monitoring

Gradually increasing throughput of high-speed networks puts continuous pressure on the performance of operations over a stream of network data. Probably the most affected operation in the area of network security and monitoring is pattern matching, which is in the core of widely deployed intrusion detection systems (IDSes) like Snort, Suricata and Bro. This paper therefore proposes several optimiz...
