Network Intrusion Detection Systems (NIDSs) monitor network traffic for suspicious activity and alert the system or network administrator. With the onset of gigabit networks, current generation networking components for NIDS will soon be insufficient for numerous reasons; most notably because the existing methods cannot support high-performance demands. Field-Programmable Gate Arrays (FPGAs) are an attractive medium to handle both high throughput and adaptability to the dynamic nature of intrusion detection. In this paper, the authors design an FPGA-based architecture for anomaly detection in network transmissions.
