Design and Development of Web-based Expert System to Detect Network Intrusion

Abstract

It is very important that the security mechanisms of a system are designed so as to prevent unauthorized access to system resources and data. However, completely preventing breaches of security appear, at present, unrealistic. We can, however, try to detect these intrusion attempts so that action may be taken to repair the damage later. Expert system (ES) has been proposed to be the beter solution of reasoning on the existing problems on the basis of expert knowledge. Experts 'brain' are stored in a database called a knowledge base and then made the rules to give decisions in accordance with the knowledge base.In this research, knowledge base taken from the expert and journal. Expert system will be used to determine or predict the occurrence of intrusion detection systems based on the feature above. By simple means, any data packet is going to be examined by ES, which initially stores knowledge about intrusion characteristics from database as variables. The result of this research is anomaly packet already detected by the application according to the rule based on the expert and the journal. Keywords: anomaly packet, expert system, intrusion, knowledge base, network packet.
