Abstract: Aiming at the problem of low detection rate of U2R attacks in IDS, this paper proposes a model that combined an improved artificial bee colony algorithm (ABC) with the optimized random forest (RF). Firstly, the model improved the initialization method and search strategy of the traditional ABC, optimized the method of ranking of feature importance scores in the traditional RF. Then the model combined the two improved algorithm. Experiments with NSL-KDD datasets show that the attack detection model based on the improved artificial bee combined with the optimization random forest algorithm (RF-IABC) can extract the optimal feature set of attack type accurately, then classify and predict the attack data, improve the detection rate of U2R type attacks by IDS effectively.

Key words: IDS, U2R attacks, improved artificial bee colony, optimized random forest
