  • Publication number: 20120331553
    Abstract: A dynamic signature creation and enforcement system can comprise a tap configured to copy network data from a communication network, and a controller coupled to the tap. The controller is configured to receive the copy of the network data from the tap, analyze the copy of the network data with a heuristic to determine if the network data is suspicious, flag the network data as suspicious based on the heuristic determination, simulate transmission of the network data to a destination device to identify unauthorized activity, generate an unauthorized activity signature based on the identification, and transmit the unauthorized activity signature to a digital device configured to enforce the unauthorized activity signature.
