摘要
目前的入侵检测存在一些问题,针对这些问题,对遗传算法在入侵检测中的应用进行了研究,讨论了适应度函数的构造,并对种群的确定、选择算子、交叉算子进行了改进,在此基础上提出了一种基于改进遗传算法的入侵检测模型,并通过实验验证了它的可行性。
The existing intrusion detection systems have a number of problems. To settle the problems, the paper researched the application of genetic algorithms in intrusion detection system, discussed the fitness function structure and improved population choice and selection operator and crossover operator. In this foundation, it founded an intrusion detection model based on improved genetic algorithm and proved that the model was feasibility by experimentation.
