Sequence alignment-based detection method for resource misuse in information systems
Gaoyu Zhang, Xiaoxia He, Zhizhao Zhou, Chao Wang · 2013
In information systems, it is challenging to detect resource misuse behaviors of insiders with authorized access. A detection method based on sequence alignment is proposed in this thesis. It extracts the behavior pattern of the user accessing resource and finds out the abnormal behaviors through comparing the accessing behaviors with the accessing patterns. Simulation experiments are carried out to show the effectiveness of this detection method presented.
