Abstract: An n-tiering security threat inference and correlation apparatus (100) for monitoring and anticipating cyber attacks is disclosed. The apparatus comprises a plurality of groups of inference-correlation systems (106(a, b)-114(a, b)), each group arranged with at least one inference system and at least one associated correlation system configured to monitor at least one network; and an input/output (I/O) system (102) configured to receive security events, and broadcast the received security events to the plurality of groups of inference-correlation systems; wherein the respective groups of inference-correlation systems are configured to process only the broadcasted security events relevant to the respective networks to identify the cyber attacks. A method of operating the apparatus is also disclosed.

Abstract: An intrusion protection system and method protect host computers of a computer network from network intrusions. All inbound and outbound transmissions of individual host computers are monitored to detects any unauthorised events. The Once an unauthorised event is detected the inbound and outbound transmissions of a host computer are locked down, thereby isolating the host computer from the rest of the computer network. A global network security provider provides further security services remotely.
