A method and apparatus for processing flow specification (Flowspec) messages to one or more of a plurality of customer networks by a controller device coupled to the plurality of customer networks. Preferably a network controller monitors network traffic flowing through each of the customer networks for detecting a network attack in one of the plurality of customer networks, via monitoring of the network traffic. Upon detection of a network attack, a Flowspec message is generated for the customer network detected to be under network attack wherein the Flowspec message is configured specifically for that customer network. The generated Flowspec message is transmitted to the customer network detected to be under network attack for implementation by the customer network for mitigation of the detected network attack.

Flowspec message processing apparatus and method

A computer-implemented method and system for managing and configuring flow specification (FlowSpec) messages for a customer network by a controller device coupled to the customer network. Network traffic is monitored by the controller device flowing through the customer network detect a network attack in the customer network. The controller device enables a network user to configure a Flowspec message responsive to the detected network attack. The controller device preferably enables the network user to either 1) manually configure a FlowSpec message or 2) configure a Flowspec message utilizing one or more pre-existing FlowSpec rulesets preferably defined for that customer network. The controller device then enables the network user to either 1) display to the network user the mitigation actions to be performed by the configured Flowspec message and save the configured Flowspec message in a data repository without announcement of the configured Flowspec message to the customer network; or 2) announce the configured Flowspec message to the customer network and save the configured Flowspec message in a data repository responsive to selection by the network user.

System and method for managing Flowspec mitigations

A method for configuring a network monitoring device is provided. A plurality of flow records is received. The plurality of flow records is analyzed according to user-specified criteria to identify one or more network traffic patterns. A plurality of network entities associated with the one or more identified network traffic patterns is identified. A managed object including the identified plurality of network entities is generated.

Using a flow database to automatically configure network traffic visibility systems

A method for encoding domain name information into flow records includes receiving a flow record. The flow record includes initial network flow information in a standard flow record format including at least a source address and a destination address. Domain name information associated with each of the source address and destination address is retrieved from a database. The domain name information is encoded into the received flow record while maintaining the initial network flow information to yield an enhanced flow record.

Augmenting network flow with passive DNS information

A system and method are provided to select mitigation parameters. The method includes receiving selection of at least one mitigation parameter, accessing a selected portion of stored network traffic or associated summaries that corresponds to a selectable time window, applying a mitigation to the selected portion of the stored network traffic or associated summaries using the selected at least one mitigation parameter, and outputting results of the applied mitigation.

System and method to select and apply hypothetical mitigation parameters

A method for configuring a network monitoring device is provided. One or more performance metrics associated with one or more thresholds to be configured are received from a user. Historical network traffic flow information associated with a previously detected malicious activity is analyzed to identify characteristic values for the one or more performance metrics. Threshold values are automatically configured based on the identified characteristic values.
