Masqueraders in computer intrusion detection are people who use somebody else's computer account. We i n v estigate a number of statistical approaches for detecting masqueraders. To e v aluate them, we collected UNIX command data from 50 users and then contaminated the data with masqueraders. The experiment w as blinded. We show results from our methods and two approaches from the computer science community.
Related to this environment, Schonlau et al. REF investigate a number of statistical approaches for detecting masqueraders.
