Online event registration with minimal privacy violation

In order to detect network threats, traffic inspection needs to be performed. Due to privacy concerns, results from these inspections can only be shared with semi-trusted parties after filtering and anonymisation has been applied. In this literature study, the effects of anonymisation on intrusion detection systems is performed. To understand the current state and future of network anonymisation systems, existing tools and frameworks are compared. This comparison gives us a clear view on the problematic areas of these systems. An important requirement of such a system, is that it can operate at line-rate speeds. This paper proposes two models for an anonymisation system and an approach to come to a set of privacy policies that have a close relation to the targeted threat rules.
