This paper discusses solutions to protect the privacy of users during the application of intrusion de-tection systems (IDS) and introduces the notion of multilateral secure IDS. The surveillance of users by an IDS threatens their privacy. However, an IDS depends on data gathered by monitoring and must be able to unambiguously identify an intruder in case of an emergency. To mediate between the con-trary interests of an IDS and the monitored users an IDS must obey the principles of data avoidance and reduction. Corresponding techniques concerning authentication and anomaly detection are dis-cussed in this paper. The protection of the increasingly complex tele and data communication networks is a critical task, but the detection, repulse and prevention of abuse by in- and outsiders becomes more and more difficult. Intrusion Detection Systems (IDS) provide a promising technique to enhance the security of complex information infrastructures. But their application mustn’t weaken the security and privacy of the
