  • Publication number: 20250383762
    Abstract: Systems and methods for providing interactive visualizations of traffic characteristics within a network include determining, for one or more applications associated with a tenant of a cloud-based system, application information associated with each of the one or more applications; providing, via a Graphical User Interface (GUI), an interactive visualization of the application information associated with each of the one or more applications; and responsive to one or more selections being made via the interactive visualization, enabling one or more cloud-based security functions based on the one or more selections.

  • Patent number: 12483596
    Abstract: Systems and methods for browser fingerprinting and control for private application protection include monitoring access to one or more private applications; performing one or more compliance checks on any of the user and the browser used to access the one or more private applications; and performing one or more actions based on a result of the one or more compliance checks. These steps are performed in order to prevent users from accessing private applications via compromised or vulnerable browsers.

  • Publication number: 20250267158
    Abstract: Systems and methods for active directory protection in zero trust networks. In an embodiment, steps include performing inline monitoring of traffic associated with a cloud-based system; detecting one or more active directory protocols based on the inline monitoring; classifying the traffic as being associated with any of the one or more active directory protocols; inspecting the traffic associated with the one or more detected active directory protocols; and generating one or more active directory logs based on the inspecting and classifying.

  • Publication number: 20250193025
    Abstract: Systems and methods for automated certificate generation and management inside zero trust private networks. Various methods include monitoring access to one or more private applications; responsive to identifying a request to access an application of the one or more private applications, generating a certificate; providing the generated certificate to a broker; and utilizing the generated certificate to provide access to the application by stitching together a connection between a user and the application.

  • Patent number: 8441942
    Abstract: A method and system of loop detection for improving network performance and data integrity over a communications network are disclosed. A process is capable of transmitting a diagnostic packet stream from a source object to a destination object. The diagnostic packet stream, in one embodiment, is an IEEE 802.1ag continuity check message and is transported to a destination object periodically across a communications network. Upon receipt of a returning packet stream from the destination object, the process broadcasts loop detection at a port level in response to the comparison between the returning packet stream and the diagnostic packet stream.

  • Publication number: 20020023719
    Abstract: An improvement to chemical-mechanical polishing. The improvement includes using a buffing pad having a geometrically optimized shape along with optimizing the buff head diameter, offset O and overlay L. In one embodiment, the buffing pad is smaller than the buff head and is mounted eccentrically. In another embodiment, the buffing pad has a generally square outer shape. In another embodiment, the buff pad is circular and is the same size as the circular buff head. In another embodiment, the buffing pad has at least three radially extending arms. The optimal configuration is determined iteratively for a selected process by changing the buffing pad shape, buff head diameter, the offset and the overlay. For example, increasing the offset generally tends to increase the removal rate toward the edge of the wafer. Increasing the overlap generally tends to increase the removal rate toward the center of the wafer.
