Patent number: 11863921Abstract: An application and network analytics platform can capture telemetry from servers and network devices operating within a network. The application and network analytics platform can determine an application dependency map (ADM) for an application executing in the network. Using the ADM, the application and network analytics platform can resolve flows into flowlets of various granularities, and determine baseline metrics for the flowlets. The baseline metrics can include transmission times, processing times, and/or data sizes for the flowlets. The application and network analytics platform can compare new flowlets against the baselines to assess availability, load, latency, and other performance metrics for the application. In some implementations, the application and network analytics platform can automate remediation of unavailability, load, latency, and other application performance issues.Type: GrantFiled: May 5, 2023Date of Patent: January 2, 2024Assignee: Cisco Technology, Inc.Inventors: Ashutosh Kulshreshtha, Omid Madani, Vimal Jeyakumar, Navindra Yadav, Ali Parandehgheibi, Andy Sloane, Kai Chang, Khawar Deen, Shih-Chun Chang, Hai Vu

Patent number: 11706239Abstract: Systems, methods, and non-transitory computer-readable storage media are disclosed for detecting vulnerabilities in real-time during execution of a process or an application. In one example, a device may have one or more memories storing computer-readable instructions and one or more processors configured to execute the computer-readable instructions to obtain real-time process information associated with a process executing in an endpoint. The device can then determine package information for a package associated with the process based on the process information. The device can then identify at least one vulnerability associated with the package information using a database of vulnerabilities stored on a backend component of the network. The backend component may have a database of vulnerabilities for packages.Type: GrantFiled: August 26, 2020Date of Patent: July 18, 2023Assignee: Cisco Technology, Inc.Inventors: Hai Vu, Thanh Nhan Nguyen, Vaishali Palkar, Varun Malhotra, Shih-Chun Chang, Xin Liu
