A Real-Time Intrusion Detection System Based on PSO-SVM

Free registration required

Executive Summary

The success of any Intrusion Detection System (IDS) is a complicated problem due to its nonlinearity and the quantitative or qualitative network traffic data stream with irrelevant and redundant features. How to choose the effective and key features to IDS is very important topic in information security. Support Vector Machine (SVM) has been employed to provide potential solutions for the IDS problem. However, the practicability of SVM is affected due to the difficulty of selecting appropriate SVM parameters. Particle Swarm Optimization (PSO) is an optimization method, which is not only has strong global search capability, but also is very easy to implement.
