This paper presents and evaluates a NIC-based network intrusion detection system. Functions such as signature-based and anomaly-based packet classification are performed on the NIC, which has its own processor and memory. This makes the system virtually impossible to bypass or tamper with as can be the case with software-based systems that rely on the host operating system to function. This paper empirically evaluates such systems from the perspective of quality and performance (bandwidth of acceptable messages) under varying conditions of host load. The preliminary results obtained are very encouraging and leads to believe that such NIC-based security schemes could very well be a crucial part of next generation network security systems.
