  • Mitigating threats in a network
    Patent number: 9083737
    Abstract: Mitigating threats in a network includes receiving a message at a network device. The message includes device-independent parameters generated in response to a threat. The network device converts the parameters into one or more device-specific operations and then performs the operations to mitigate the threat.
    Type: Grant
    Filed: July 10, 2013
    Date of Patent: July 14, 2015
    Assignee: Cisco Technology, Inc.
    Inventors: Klaus Hermanns, James L. Fenton, Venkateswara Rao Yartagadda, Chandra S. Buduguru, Chandrahasa C. Pullagura, Rajiv Raghunarayan, Barry L. Greene, Ellis R. Dobbins
  • Anomaly information distribution with threshold
    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.

  • ANOMALY INFORMATION DISTRIBUTION WITH THRESHOLD
    Publication number: 20100058469
    Abstract: Embodiments of the present disclosure provide techniques for distributing information about possible anomalies in a network.

  • Hierarchical management of objects
    Patent number: 7370109
    Abstract: A networking environment in which a sequence of proxy forwarders are used to forward network management requests from a network management station (NMS) to a network element containing a managed object. The NMS sends a request according to a network management protocol. The sequence of proxy forwarders forward the request to the network element. The response generated by the network element is forwarded back to the NMS by the same sequence of proxy forwarders, but in the reverse direction.
