  • Patent number: 11064030
    Abstract: In one embodiment, a master on-boarding agent establishes a virtual private network (VPN) connection with a local on-boarding agent executed by a gateway of a vehicle. The master on-boarding agent receives, via the VPN connection, vehicle data obtained by the local on-boarding agent from a co-pilot system of the vehicle. The master on-boarding agent configures, based on the received vehicle data, the gateway of the vehicle with a network configuration, wherein the network configuration includes an Internet Protocol (IP) address for the gateway. The master on-boarding agent coordinates, based on the network configuration, application of a security policy to the gateway.

  • Patent number: 8677480
    Abstract: Embodiments of the present disclosure provide techniques for distributing information about possible anomalies in a network. A sensor in a network may detect packets with payloads that match an anomaly signature. Address dispersion information, for example, in the form of source and address bitmaps, may be gathered at the sensor. The address dispersion information may be distributed to one or more peer sensors if the information indicates that the number of different addresses of the detected matching packets exceeds a threshold.
