Abstract	Network security alert causal correlation aims at correlating causal related security alerts into comprehensible attack scenarios. In this paper, we propose a novel correlation criterion by evaluating the time expenses of the attacks that trigger security alerts. By taking the attack time expenses as random variables and studying their probabilistic distribution, we can calculate the temporal correlation belief metric of any two candidate alerts. To testify the feasibility, a prototype system is designed, implemented and tested with the DARPA 2000 IDS evaluation dataset. Result shows that our method is effective and efficient, providing a strong complementary support for attack scenario construction.
