Patent number: 11916874Abstract: Provided in some embodiments are systems and methods for determining a data flow path including a plurality of network devices for routing data from a first network device to a second network device; determining for the network devices one or more flow rules that specify an input for receiving data, an output for outputting data, and a role tag indicative of a role of a network device, where the role tag for one or more flow rules for a first network device of the network devices indicates a source role; distributing, to the network devices, the one or more flow rules; determining malicious activity on the data flow path; determining that the first network device is a source based at least in part on the role tag for the first network device; and sending, to the first network device, a blocking flow rule to inhibit routing of malicious data.Type: GrantFiled: March 31, 2021Date of Patent: February 27, 2024Assignee: McAfee, LLCInventors: Shivakrishna Anandam Mulka, Shankar Subramanian, Jayakrishnan Karunakaran Nair, Gopal Agrawal, Shankar Ganesh Pillaiyar Nattamai Jeyaprakash

Patent number: 10129125Abstract: In an example, there is disclosed a computing apparatus, having: a network interface to communicatively couple to a software-defined network (SDN); first one or more logic elements providing an SDN controller engine to provide a control function for the SDN; and second one or more logic elements providing a route tracing engine to: receive a tunneling notification from a network device agent, the tunneling notification associated with a network flow; and perform a backtracking traceroute operation to deterministically identify a source device for the flow. There is also disclosed a method of providing the foregoing, and one or more tangible, non-transitory computer-readable storage mediums for providing the foregoing.Type: GrantFiled: December 18, 2015Date of Patent: November 13, 2018Assignee: McAfee, LLCInventors: Gopal Agrawal, Shivakrishna Anandam Mulka

Patent number: 9917775Abstract: There is disclosed a network device having a network interface; and one or more logic elements comprising a flow table engine operable to: receive a network packet via the network interface; perform a logging action to make the network packet traceable; and notify a software-defined networking (SDN) controller of the logging action via the network interface. There is also disclosed an SDN controller having a network interface; first one or more logic elements comprising a software-defined networking (SDN) controller engine to provide SDN controller services; and second one or more logic elements comprising a route tracing engine, operable to: receive a logging action for a network packet from a network device via the network interface; and update a logging table from the logging action. There is further disclosed a method of providing the foregoing, and computer-readable mediums for providing the foregoing.Type: GrantFiled: December 22, 2015Date of Patent: March 13, 2018Assignee: McAfee, LLCInventors: Shivakrishna Anandam Mulka, Jayakrishnan Nair
