Pseudonymous Audit for Privacy Enhanced Intrusion Detection

Abstract

Intrusion detection systems can serve as powerful security audit analysis tools. But by analysing the user activities, they are affecting the privacy of the users at the same time. Pseudonymous audit can be the basis for privacy enhanced intrusion detection. In this paper, the concept of pseudonymous audit for privacy enhanced intrusion detection and its prototype realisations are presented. Furthermore it is discussed whether IT security evaluation criteria cover pseudonymous audit and the respective changes are suggested. •
