Publication number: 20240348625Abstract: An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.Type: ApplicationFiled: June 24, 2024Publication date: October 17, 2024Inventors: Navindra Yadav, Abhishek Ranjan Singh, Shashidhar Gandham, Ellen Christine Scheib, Omid Madani, Ali Parandehgheibi, Jackson Ngoc Ki Pang, Vimalkumar Jeyakumar, Michael Standish Watts, Hoang Viet Nguyen, Khawar Deen, Rohit Chandra Prasad, Sunil Kumar Gupta, Supreeth Hosur Nagesh Rao, Anubhav Gupta, Ashutosh Kulshreshtha, Roberto Fernando Spadaro, Hai Trong Vu, Varun Sagar Malhotra, Shih-Chun Chang, Bharathwaj Sankara Viswanathan, Fnu Rachita Agasthy, Duane Thomas Barlow

Patent number: 12113684Abstract: Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.Type: GrantFiled: January 18, 2022Date of Patent: October 8, 2024Assignee: Cisco Technology, Inc.Inventors: Shashidhar Gandham, Rohit Chandra Prasad, Abhishek Ranjan Singh, Navindra Yadav, Khawar Deen, Varun Sagar Malhotra

Patent number: 11902121Abstract: A method includes capturing first data associated with a first packet flow originating from a first host using a first capture agent deployed at the first host to yield first flow data, capturing second data associated with a second packet flow originating from the first host from a second capture agent deployed on a second host to yield second flow data and comparing the first flow data and the second flow data to yield a difference. When the difference is above a threshold value, the method includes determining that the second packet flow was transmitted by a component that bypassed an operating stack of the first host or a packet capture agent at the device to yield a determination, detecting that hidden network traffic exists, and predicting a malware issue with the first host based on the determination.Type: GrantFiled: August 26, 2022Date of Patent: February 13, 2024Assignee: Cisco Technology, Inc.Inventors: Khawar Deen, Navindra Yadav, Anubhav Gupta, Shashidhar Gandham, Rohit Chandra Prasad, Abhishek Ranjan Singh, Shih-Chun Chang

Patent number: 11902120Abstract: An example method can include choosing a pattern or patterns of network traffic. This pattern can be representative of a certain type of traffic such as an attack. The pattern can be associated with various components of a network and can describe expected behavior of these various components. A system performing this method can then choose a nodes or nodes to generate traffic according to the pattern and send an instruction accordingly. After this synthetic traffic is generated, the system can compare the behavior of the components with the expected behavior. An alert can then be created to notify an administrator or otherwise remedy any problems.Type: GrantFiled: June 5, 2020Date of Patent: February 13, 2024Assignee: Cisco Technology, Inc.Inventors: Rohit Chandra Prasad, Bharathwaj Sankara Viswanathan, Hoang Viet Nguyen, Vimalkumar Jeyakumar, Roberto Fernando Spadaro, Varun Sagar Malhotra, Navindra Yadav

Patent number: 10862776Abstract: Managing a network environment to identify spoofed packets is disclosed. A method includes analyzing, via a first capture agent, packets processed by a first environment in a network associated with a first host, and analyzing, via a second capture agent, packets processed by a second environment in the network associated with a second host. The method includes collecting the first data and the second data at a collector and generating a topological map of the network and a history of network activity associated with the first environment and the second environment. The method includes extracting network data from a packet and comparing the extracted network data with stored network data in the database. When the comparison indicates that the extracted network data does not match the stored network data (i.e., the reported source does not match an expected source for the packet), determining that the packet is a spoofed packet.Type: GrantFiled: June 2, 2016Date of Patent: December 8, 2020Assignee: CISCO TECHNOLOGY, INC.Inventors: Khawar Deen, Navindra Yadav, Anubhav Gupta, Shashidhar Gandham, Rohit Chandra Prasad, Abhishek Ranjan Singh, Shih-Chun Chang
