IDS Sensor Placement Using Attack Graphs

摘要

Embodiments of the present invention identify locations to deploy IDS sensor(s) within a network infrastructure and prioritize IDS alerts using attack graph analysis. An attack graph that describes exploitable vulnerability(ies) within a network infrastructure is aggregated into protection domains. Edge(s) that have exploit(s) between two protection domains are identified. Sets that contain edge(s) serviced by a common network traffic device are defined. Set(s) that collectively contain all of the edge(s) are selected. The common network traffic device(s) that service the selected sets are identified as the location(s) to deploy IDS sensor(s) within the network infrastructure.
