Types of IDS

There are several types of IDS that can be deployed to aid security administrators in their endeavors. Two types, network-based intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS) are most prevalent in modern security deployments. There are other types of IDS, however, which include file integrity and log file checkers, and decoy devices known as honeypots. Additionally, there exist hybrid systems that combine some of the different functionalities mentioned earlier. We'll discuss each of these IDS in this section.
