摘要: Intrusion detection relies on the information provided by a number of sensorsdeployed throughout protected network. Sensors operate different event streams, such as network packets and application logs, provide at abstraction levels, low-level warnings correlated alerts. In addition, sensors range from lightweight probes simple log parsers to complex software artifacts that perform sophisticated analysis. Therefore, deploying, configuring, managing, large heterogeneous is complex, expensive, error-prone activity.
