摘要: Locality as a unifying concept for understanding the normal behavior of benign users computer systems is suggested paradigm that will support detection malicious anomalous behaviors. The paper notes locality appears in many dimensions and applies to such diverse mechanisms working set IP addresses contacted during web browsing session, email with which one customarily corresponds, way pages are fetched from site. In every case intrusive behaviors violate known exist some cases, violation necessary achieve its goal. If this observation holds up under further investigation, we have powerful thinking about security activity.
