What is a "network intrusion detection system (NIDS)"?

An intrusion is somebody (A.K.A. "hacker" or "cracker") attempting to break into or misuse your system. The word "misuse" is broad, and can reflect something as  severe as stealing confidential data to something minor such as misusing your email system for spam (though for many of us, that is a major issue!).
An "Intrusion Detection System (IDS)" is a system for detecting such intrusions. IDS can be broken down into the following further categories:

Network Intrusion Detection Systems (NIDS) monitors packets on the network wire and attempts to discover if a hacker/cracker is attempting to break into a system (or cause a denial of service attack). A typical example is a system that watches for large number of TCP connection requests (SYN) to many different ports on a target machine, thus discovering if someone is attempting a TCP port scan. A NIDS may run either on the target machine who watches its own traffic (usually integrated with the stack and services themselves), or on an independent machine indiscriminately watching all network traffic (hub, router, probe). Note that a "network" IDS monitors many machines, whereas the others monitor only a single machine (the one they are installed on).
