Network Immunity: What can we learn from nature for network protection?

In this paper we analyze Network Immunity as a bio-inspired approach for detecting anomalies in communication networks. We briefly review the basic methods of Artificial Immune Systems (AIS), identify their strengths and weaknesses, and evaluate their possible applications to intrusion detection in computer networks. After an overview of related work from the area of intrusion detection we collect key challenges anticipated for the realization of Network immunity based on AIS.
