SMURFEN: A Knowledge Sharing Intrusion Detection Network
The problem of Internet intrusions has become a world-wide security concern. To protect computer users from malicious attacks, Intrusion Detection Systems (IDSs) are designed to monitor network traffic and computer activities in order to alert users about suspicious intrusions. Collaboration among IDSs allows users to benefit from the collective knowledge and information from their collaborators and achieve more accurate intrusion detection. However, most existing collaborative intrusion detection networks rely on the exchange of intrusion data which raises the privacy concern of participants.
