A distributed IDS (dIDS) consists of multiple Intrusion Detection Systems (IDS) over a large network, all of which communicate with each other, or with a central server that facilitates advanced network monitoring, incident analysis, and instant attack data. By having these co-operative agents distributed across a network, incident analysts, network operations, and security personnel are able to get a broader view of what is occurring on their network as a whole. A dIDS also allows a company to efficiently manage its incident analysis resources by centralizing its attack records and by giving the analyst a quick and easy way to spot new trends and patterns and to identify threats to the network across multiple network segments. This article will discuss distributed intrusion detection systems, including the general setup of a dIDS and a fictional case study to demonstrate the distributed analysis abilities.
