  • Systems and methods utilizing peer measurements to detect and defend against distributed denial of service attacks
    Patent number: 9838421
    Abstract: A method, operated by a Software Defined Networking (SDN) controller associated with an Autonomous System (AS) with one or more peering points, each peering point with an associated router communicatively coupled to the SDN controller, the method for detecting and defending against Distributed Denial of Service (DDoS) attacks, and the method includes receiving data from the one or more peering points; detecting malicious traffic at the one or more peering points; determining a peer quality measurement for the one or more peering points; and communicating the peer quality measurement and other data associated with the malicious traffic to one or more other SDN controllers, associated with Autonomous Systems connected through the one or more peering points, to facilitate convergence of the peer quality measurement back to a nominal level.

  • Systems and methods to detect and characterize fake cell towers
    Patent number: 9485660
    Abstract: Systems and methods to detect and characterize fake cell towers in a network operator's network include receiving live data comprising any of crowd-sourced data and tower data; performing live data analysis on the live data and reference data; and detecting the fake cell towers based on the live data analysis. Optionally, spectrum data captured at cell towers by a baseband processor coupled to backhaul equipment can be used as additional input.
