Abstract: Sequence alignment is a basic information processing method in bioinformatics and useful for discovering functional, structural, and evolutionary information in biological sequence. Typical sequence alignment algorithms of N-W and S-W are described and analyzed in this paper. S-W algorithm is introduced into masquerading intrusion detection and the experiment substantiates the high-sensitive detection performance of the algorithm.

Key words: sequence alignment, intrusion detection, masquerade, S-W algorithm
