[Chung95] M. Chung, N. Puketza, R.A. Olsson, B. Mukherjee, Simulating Concurrent Intrusions for Testing Intrusion Detection Systems: Parallelizing Intrusions. Proc. of the 1995 National Information Systems Security Conference. Baltimore, Maryland, October 10-13, 1995, pp. 173-183. [This paper shows a method for parallizing attack scripts so as to test intrusion detection systems against variations on known attacks. Results indicate that some intrusion detection systems produce substantially different results when attack patterns are varried.]
