With the growing amount and kinds of network intrusion, multi-stage attack is becoming the one of the main methos of the network security threaten. The hidden Markov model is a kind of probabilistic model, which is widely used in speech recognition, text and image processing. In this paper, a Multi-stage Attack Detection Algorithm Based on Hidden Markov Model is proposed.And inorder to improve the performance of this algorithm,aother algorithm aims at false positive filter is also put forward. Experiments show that the algorithm has good perfomance in multi-stage attack detection.
