Beehive: Large-Scale Log Analysis for Detecting Suspicious Activity in Enterprise Networks

Beehive: Large-Scale Log Analysis for Detecting Suspicious Activity in Enterprise Networks
Presenter: Dr. Alina Oprea (RSA Laboratories)

Abstract:
Currently, many organizations keep large volumes of log data collected by various security products. This data is mostly used today for forensic analysis once an attack has been discovered or an incident triggered through some external mechanism. We present a novel system called Beehive that mines and automatically extracts knowledge from these various data sources available in our enterprise. Beehive profiles the typical behavior of hosts over extended periods of time, extracts features representative of different aspects of host behavior and identifies hosts that deviate from normal activity. By using a behavior-based approach to detecting security incidents, Beehive improves on signature-based techniques prevalent in industry products. We have evaluated Beehive on several months of log data collected in our enterprise and show that Beehive is able to identify malicious events and policy violations within the enterprise network which would otherwise go undetected.
