摘要: Abstract IBM's emergency response service provides real-time intrusion detection (RTID) services through the Internet for a variety of clients. As number clients increases, volume alerts generated by RTID sensors becomes intractable. This problem is aggravated fact that some may generate hundreds or even thousands innocent per day. With an eye towards managing these more effectively, data mining group analyzed database reports. The first objective was approach characterizing “normal” stream from sensor. Using such models tuned to individual sensors, we then developed methodology detecting anomalies. In contrast many popular approaches, decision filter alarm out not takes into consideration context in which it occurred and historical behavior sensor came from. Our second identify all different profiles our Based on their history alerts, discovered several types clients, with alert behaviors thus monitoring needs. We present issues encountered, solutions, findings, discuss how results be used large-scale operations.
