An improved method for analyzing computer network security has been developed. The method first establishes multiple nodes, where each node represents an actor, an event, a condition, or an attribute related to the network security. Next, an estimate is created for each node that reflects the ease of realizing the event, condition, or attribute of the node. Attack paths are identified that represent a linkage of nodes that reach a condition of compromise of network security. Next, edge probabilities are calculated for the attack paths. The edge probabilities are based on the estimates for each node along the attack path. Next, an attack graph is generated that identifies the easiest conditions of compromise of network security and the attack paths to achieving those conditions. Finally, attacks are detected with physical sensors on the network, that predict the events and conditions. When an attack is detected, security alerts are generated in response to the attacks.

System and method for cyber security analysis and human behavior prediction

A method and system for segmenting a network including a plurality of hosts is disclosed. In an example embodiment, the network is a provider network. The method receives network activity information describing network traffic between hosts of the plurality. The method generates observations from the network activity information and organizes the observations into clusters. The method determines a profile for each cluster that corresponds to a potential system type implemented by one or more of the hosts of the medical provider network. The method determines segments within the provider network based on the profiled system types.
