An IDS is an intrusion detection system, check out this link for a better description...
http://www.barbedwires.com/faqs.htm#8 8--What is an IDS and how does it work? The intrusion detection device listens to packets on the network and compares the network traffic to a pattern database to detect any intrusion attempts. By using software agents to inspect network traffic, either in real time or in retrospect (through vulnerability assessment); IDS can detect suspicious commands or the kind of syntax that may signal an attack. It could preempt a denial-of-service (DoS) attack, for example, as it is capable of detecting characteristically unusual patterns in traffic flow (such as massive and simultaneous connection requests). Today, most IDS solutions work by inspecting traffic for certain types of what is called "attack signatures." An IDS agent collects data on the traffic moving through the network and compares that data to a list of attack signatures. If there is a match, an alarm is sounded and appropriate action is taking.
