Abstract: Passive network monitoring is required for the operation and maintenance of communication networks as well as to detect frauds and attacks. Typically, raw packetlevel traffic traces are collected using suitable traffic probe devices and fed to monitoring applications (IDSs, antivirus, etc.) for analysis, with potential risks for the legitimate privacy rights of the customers. This paper aims to discuss the technical feasibility and the underlying research challenges of a two-tiered privacypreserving network monitoring system, where carefully designed data rotection mechanisms can coexist with suitably adapted monitoring applications.
