Locality-based server profiling for intrusion detection

Abstract

Detection of intrusion on network servers plays an ever more important role in network security. This paper investigates whether analysis of incoming connection behavior for properties of locality can be used to create a normal profile for network servers. Intrusions can then be detected due to their abnormal behavior. Experiments show that connections to a typical network server do in fact exhibit locality, and attacks can be detected through their violation of locality. © 2008 Springer-Verlag Berlin Heidelberg.
