  • Publication number: 20180198812
    Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media for detecting anomalies in network traffic patterns with a network device by analyzing patterns in network traffic packets traversing the network. Various embodiments include clustering received network traffic packets into groups. The network device receives data packets originating from an endpoint device and analyzes the packets for patterns. The network device may apply a traffic analysis model to the clusters to obtain context classes. The network device may select a behavior classifier model based, at least in part, on the determined context class, and may apply the selected behavior classifier model to determine whether the packet behavior is benign or non-benign.

  • Publication number: 20180124080
    Abstract: Various embodiments include methods of protecting a computing device within a network from malware or other non-benign behaviors. A computing device may monitor inputs and outputs to a server, derive a functional specification from the monitored inputs and outputs, and use the functional specification for anomaly detection. Use of the derived functional specification for anomaly detection may include determining whether a behavior, activity, web application, process or software application program is non-benign. The computing device may be the server, and the functional specification may be used to determine whether the server is under attack.

  • Publication number: 20180124018
    Abstract: Aspects may relate to a server comprising: an interface to receive a service request; and a processor coupled to the interface to receive the service request, the processor configured to: implement a firewall appliance for the service request; operate a first micro-security application to generate an anomaly alert for the service request; and operate a second micro-security application to receive the anomaly alert from the first micro-security application or from another server's micro-security application and to determine whether the service request corresponds to a non-benign behavior.

  • Patent number: 8300532
    Abstract: A method may include receiving a packet at an ingress line interface in a forwarding plane of a network element, the packet including header information. The method may also include conducting a flow table lookup in the forwarding plane to identify an existing flow for the packet and determining, in the forwarding plane and based on the header information, whether a predicted flow can be identified for the packet if an existing flow can not be identified. The method may further include performing a service access control list (ACL) lookup in the forwarding plane if a predicted flow can not be identified; and forwarding the packet to one of a services plane or an egress line interface in the forwarding plane based on one of the existing flow, the predicted flow, or the service ACL lookup.
