|Project Description: ||Intrusion Detection (ID) is a type of security management system for computers and networks. An ID system gathers and analyzes information from various areas within a computer or a network to identify possible security breaches, which include both intrusion (attacks from outside the orgization) and misuse (attacks from within the organization). These systems are an important component of defensive measure to protect computer systems and networks from potential threats and vulnerabilities. Web-based Network Intrusion Detection Expert System (WNIDES) is implemented using Java Expert Shell System (JESS). The WNIDES expert system uses Snort to capture network packets; Snort is an open source network packet sniffer program. This technical report presents a literature survey of different types of intrusion detection systems and the various methods in developing them. It presents the design and implementation of a WNEDES using JESS.
