Intrusion detection systems (IDSs) monitor computer systems, record audit data and analyze the collected audit data in order to detect misuse. The recorded audit data documents user behavior, and contains personal data of the system users. Hence,MoreIntrusion detection systems (IDSs) monitor computer systems, record audit data and analyze the collected audit data in order to detect misuse. The recorded audit data documents user behavior, and contains personal data of the system users. Hence, collecting and processing audit data for misuse detection conflicts with pertinent privacy law.A viable solution is replacing personal data with pseudonyms in audit data.

During normal operation, the IDS analyzes the pseudonymized audit data, respecting the privacy of users. If the IDS detects a misuse scenario, the personal data of only those user(s) is revealed, who are involved in the misuse.Privacy-Respecting Intrusion Detection introduces the concept of technical purpose binding, which restricts the linkability of pseudonyms in audit data to the amount necessary for misuse detection. Also, it limits the recovery of the original personal data to pseudonyms involved in a detected misuse scenario.

This book includes case studies demonstrating this theory and solutions that are constructively validated by providing algorithms.
