入侵检测(ID )是保障网络安全的必要手段之一,将数据挖掘引入入侵检测中使其可以适应海量审计数据的处理,同时可以提高检测的均衡性和响应时间。文章提出了一种基于随机森林(random forest ,RF)的入侵检测模型(1R‐RF),针对RF模型面对高维网络审计数据选择属性时过度随机导致的元分类器效率不高的问题,开展了基于One‐R快速属性评价的研究。实验证明,将基于One‐R的RF用于入侵检测后有较好的时空性能、较低的误报率和漏报率,对于各种攻击行为有着较为均衡的检测率。

The intrusion detection(ID) is one of the critical techniques to protect the security of net‐work .The intrusion detection model becomes more proper to process large amount of audit data and achieves balanced detecting performance and low corresponding time by data mining technique intro‐duced .In this paper ,a novel intrusion detection model based on the random forest (1R‐RF ) is pro‐posed .Aiming at improving the base tree’s performance of RF w hen over‐randomly selecting features from high dimensional audit data ,the algorithm for feature selection based on One‐R(1R) is studied . The experimental results show that the 1R‐RF intrusion detection model has good space‐time perform‐ance and has lower rates of false and loss alarms .Additionally ,this model has balanced detecting per‐formance with regard to various intrusion attacks .
