Network intrusion detection systems provide proactive defense against security threats by detecting and blocking attack-related traffic. This task can be highly complex, and therefore, software-based network intrusion detection systems have difficulty in handling high speed links. This paper describes the design and implementation of a high-performance network intrusion detection system that combines the use of software-based network intrusion detection sensors deployment. In large network environments multiple intrusion detection sensors are needed to adequately monitor network traffic.
