Abstract

This paper describes a course module developed to help computer security students understand a use of the X2-, chi-square, goodness-of-fit test to detect possible intrusions. Detecting intrusions not only provides feedback to help design, but also to implement prevention techniques to harden information systems. As statistical or mathematical techniques can identify intrusions, there is a need to introduce these statistical concepts to students in information assurance, network, forensics and software security courses as they attempt to understand intrusions and plan possible responses.
