Network intrusion detection systems identify security threats by detecting malicious activity such as scans, denial of service attacks and unauthorised access through the examination of network traffic. They are installed at strategic points on the network to monitor traffic to and from all hosts on the network.

In simple terms these systems could be described as a packet sniffer that also analyses the captured packets.
