Explanation

Knowledge-based Intrusion Detection Systems use a database of previous attacks and known system vulnerabilities to look for current attempts to exploit their vulnerabilities, and trigger an alarm if an attempt is found. Application-Based ID System - "a subset of HIDS that analyze what's going on in an application using the transaction log files of the application." Host-Based ID System - "an implementation of IDS capabilities at the host level. Its most significant difference from NIDS is intrusion detection analysis, and related processes are limited to the boundaries of the host." Network-Based ID System - "a network device, or dedicated system attached to teh network, that monitors traffic traversing teh network segment for which it is integrated."
