Abstract

This thesis first explores how intrusion detection (ID) techniques can be used to provide an extra security layer for today‟s typically security-unaware Internet user. A review of the ever-growing network security threat is presented along with an analysis of the suitability of existing ID systems (IDS) for protecting users of varying security expertise. In light of the impracticality of many IDS for today‟s users, a web-enabled, agent-based, hybrid IDS is proposed. The motivations for the system are presented along with details of its design and implementation. As a test case, the system is deployed on the DCU network and results analysed. One of the aims of an IDS is to uncover security-related issues in its host network. The issues revealed by our IDS demonstrate that a full DCU network security assessment is warranted. This thesis describes how such an assessment should be carried out and presents corresponding results. A set of security-enhancing recommendations for the DCU network are presented.
