CIDS: An agent-based intrusion detection system

The paper describes security agent architecture, called CIDS, which is useful as an administrative tool for intrusion detection. Specifically, it is an agent-based monitoring and detection system, which is developed to detect malfunctions, faults, abnormalities, misuse, deviations, intrusions, and provide recommendations (in the form of common intrusion detection language). The CIDS can simultaneously monitor networked-computer activities at multiple levels (user to packet level) in order to find correlation among the deviated values (from the normal or defined policy) to determine specific security violations. The current version of CIDS (CIDS 1.4) is tested with different simulated attacks in an isolated network, and some of those results are reported here. © 2005 Elsevier Ltd. All rights reserved
