Artificial immune system has made many contributions to network security areas, but there are still problems of insufficient detection range and high time cost. This paper presents a Hybrid Detector (HD) mechanism in which temporal logic antigens are proposed. The HD mechanism is constructed by using the advantage of temporal logic to describe time-varying behaviors in system. Finally, simulation experiments were carried out on KDD99 and NSL-KDD datasets. Experimental results show that the proposed method can extend the detection range and improve the detection rate. This work proves the possibility of applying temporal logic to AIS system.
