Abstract

An intrusion detection system detects intrusion events in a computer network and assesses the vulnerability of the network components to the detected events. The intrusion detection system includes a scanner, one or more sensors and a security console for operation within a networked computing environment. A sensor of the intrusion detection system monitors the networked computing environment for possible intrusion events representing an unauthorized access or use of the network resources. In response to detecting an intrusion event, the sensor generates a scan request for handling by a scanner. This request initiates a scan of the target computer by the scanner to determine the vulnerability of the target to the attack. Based on this vulnerability analysis, the intrusion detection system evaluates the severity of the detected intrusion event and issues an alert having a priority corresponding to the severity of the intrusion.
