A distributed security architecture may include: a mobile anti-tamper hardware policy enforcement point configured to control communication behaviors of a mobile or stationary client by enforcing communication policies within a policy decision point; an anti-tamper hardware policy decision point encapsulated within the anti-tamper hardware policy enforcement point; a policy exchange channel for policy distribution modes configured to distribute and/or update communication and routing security policies to the client; a context manager configured to handle system-wide status change update signaling; and an authentication manager configured to provide clients with registration and credential/role assignments based on access policies. The distributed security architecture may be configured to provide open system interconnection layer 3.5 policy-based secure routing, and open system interconnection layer 2 policy-based mandatory access control address filtering to provide secure communication and computing for layers 4, 5, 6, and 7.

Distributed security architecture

Computer based method for generation of a graph representation of a rule set for searching data transiting a network using a graph-based search model. A set of rules that describe strings or patterns of data to be identified in the data set, is expressed as a graph. As blocks of the data set are obtained for processing, the state of the graph is updated based upon the value of the received data block. The transition to the next state depends upon both the current state and the received data block. As blocks of data are received and processed, the graph is traversed until one of the rules is identified.
