Efficient Wu-Manber Pattern Matching Hardware for Intrusion and Malware Detection

03/01/2020 ∙ by Monther Aldwairi, et al. ∙ 0

Network intrusion detection systems and antivirus software are essential in detecting malicious network traffic and attacks such as denial-of-service and malwares. Each attack, worm or virus has its own distinctive signature. Signature-based intrusion detection and antivirus systems depend on pattern matching to look for possible attack signatures. Pattern matching is a very complex task, which requires a lot of time, memory and computing resources. Software-based intrusion detection is not fast enough to match high network speeds and the increasing number of attacks. In this paper, we propose special purpose hardware for Wu-Manber pattern matching algorithm. FPGAs form an excellent choice because of their massively parallel structure, reprogrammable logic and memory resources. The hardware is designed in Verilog and implemented using Xilinx ISE. For evaluation, we dope network traffic traces collected using Wireshark with 2500 signatures from the ClamAV virus definitions database. Experimental results show high speed that reaches up to 216 Mbps. In addition, we evaluate time, device usage, and power consumption.
