Patent number: 12166772Abstract: Systems and methods provide for synergistic domain name system DNS security updates for an enterprise network operating under a Software Defined Wide Area Network (SD-WAN). A system may be configured to collect positive and/or negative unified threat defense (UTD) results, deploy a rules-based model that, when a threat or clearance is detected across several SD-WAN edge network devices, triggers an update to a local security blacklist/whitelist, wherein the update comprises a signature, and push the update to other devices that have not yet seen the threat or clearance.Type: GrantFiled: August 5, 2022Date of Patent: December 10, 2024Assignee: Cisco Technology, Inc.Inventors: Vamsidhar Valluri, Vinay Prabhu, Sarah Adelaide Evans, Suraj Rangaswamy

Publication number: 20240348652Abstract: Increasing use of web-based applications or Software-as-a-Service and IoT devices within enterprise networks increases the variety of network traffic and variables for consideration in managing security posture, which includes policy management. A security posture management system as disclosed herein leverages application identification and device discovery from ongoing collection and analysis of network traffic data to manage policies at device granularity allowing tailored security posture management. The system can tailor policies to handle network traffic depending on identified application and device type inputs obtained from the ongoing collection and analysis. The security posture management system can configure SD-WAN construct based parameters of a policy to tailor policies for different application traffic from different types of devices.Type: ApplicationFiled: April 28, 2023Publication date: October 17, 2024Inventors: Arunkumar Mutharasanallur Desigan, Vamsidhar Valluri, Venkata Sarat Kumar Vajrapu, Gong Cheng, Madhusudhan Donthi Nagaraju, Anil Kumar Reddy Sirigiri

Patent number: 11870755Abstract: Systems and methods provide for provisioning a dynamic intent-based firewall. A network controller can generate a master route table for network segments reachable from edge network devices managed by the controller. The controller can receive zone definition information mapping the network segments into zones and Zone-based Firewall (ZFW) policies to apply to traffic between a source and destination zone specified by each ZFW policy. The controller can evaluate a ZFW policy to determine first edge network devices that can reach first network segments mapped to the source zone specified by the ZFW policy, second edge network devices that can reach second network segments mapped to the destination zone specified by the ZFW policy, and routing information (from the route table) between the first network segments, the first and second edge network devices, and the second network segments. The controller can transmit the routing information to the edge network devices.Type: GrantFiled: October 26, 2021Date of Patent: January 9, 2024Assignee: Cisco Technology, Inc.Inventors: Vamsidhar Valluri, Saravanan Radhakrishnan, Anand Oswal, Vinay Prabhu, Sarah Adelaide Evans, Suraj Rangaswamy

Patent number: 11025632Abstract: In one embodiment, a device of a vehicle receives a packet comprising a source address, a destination address, an internet protocol (IP) encapsulated controller area network (CAN) message, and CAN message identifier information. The device compares the source address, the destination address, and the CAN message identifier information to an access control list (ACL). The device makes a determination that delivery of the CAN message to the destination address would be a policy violation based on the comparison. The device drops the packet based on the determination that delivery of the CAN message to the destination address would be a policy violation.Type: GrantFiled: December 5, 2018Date of Patent: June 1, 2021Assignee: Cisco Technology, Inc.Inventors: Anand Venkata Ramana Murthy Akella, Vishnuprasad Raghavan, Vamsidhar Valluri, Raghuram S.
