摘要

In this paper, we propose a new method of rule acquisition which is based on Particle Swarm Optimization Algorithm to produce a high performance rule database for network intrusion detection. The latest Quantum-behaved Particle Swarm Optimization (QPSO) is introduced and improved to overcome trapping local optimal solution. In addition, fitness function which is more adapt to practical conditions of intrusion detection is proposed, which can screen out rules which have lower rate of false alarm from the process of rule acquisition. The experimental results show that this algorithm can improve effectively the global search performance and obtain preferable rule database for intrusion detection.
