  • Method and system for detecting attack path connections in a computer network using state-space correlation
    Patent number: 8125898
    Abstract: A method of determining correlated flows in a network may include obtaining times of arrival and corresponding flows for data units in the network (1020) and assigning weights to a set of data units based on respective times between the set of data units and one data unit (1030). A probability matrix representing interflow connections in the network may be updated based on the assigned weights (1040).
