ABSTRACT:
A dynamic network security system (20) responds to a security attack (92) on a computer network (22) having a multiplicity of computer nodes (24). The security system (20) includes a plurality of security agents (36) that concurrently detect occurrences of security events (50) on associated computer nodes (24). A processor (40) processes the security events (50) that are received from the security agents (36) to form an attack signature (94) of the attack (92). A network status display (42) displays multi-dimensional attack status information representing the attack (92) in a two dimensional image to indicate the overall nature and severity of the attack (92). The network status display (42) also includes a list of recommended actions (112) for mitigating the attack. The security system (20) is adapted to respond to a subsequent attack that has a subsequent signature most closely resembling the attack signature (94).
