  • Patent number: 11956219
    Abstract: Described embodiments provide systems and methods for preventing unauthorized access of information from a resource. A device intermediary between a client and a server in a session can receive a first request from the client that includes a first uniform resource locator (URL) of the server. The device may receive a response from the server that includes a second URL. The device may update the response by including a client identifier for the session in a set-cookie field, obfuscating the second URL into a string, and replacing the second URL in the response with the string. The device may receive a second request that includes a candidate client identifier, and a third URL. The device may determine whether the second request is valid, by at least one of: matching the candidate client identifier with the client identifier, and determining whether the second URL is recoverable using the third URL.

  • Publication number: 20220329624
    Abstract: A system to identify automated submissions of web pages, such as those submitted by bots, in real time. The system comprising a processor configured to update an initial version of a requested web page with at least one hidden field, transmit the updated web page to the client, then, upon receipt parse the completed web page, and identify if a data entry is associated with the at least one hidden field. Where a data entry is associated with the at least one hidden field, the system blocks the transmission of the completed web page to the server. Where a data entry is not associated with the at least one hidden field the system removes the at least one hidden field, and transmits the final web page to the server.

  • Patent number: 11349812
    Abstract: Described embodiments provide systems and methods for learning across multiple application delivery controllers and updating settings across the application delivery controllers. A profile can be generated based on selection of a set of intermediary devices managed by a device. The set of intermediary devices configured to load balance data of an application hosted in different computing environments. Activity can be identified at the intermediary devices with use of a firewall. The activity having an appearance of a malicious attack on at least one intermediary device of the set. The device can determine if the activity is permissible or a violation based on a comparison of an aggregation of data records for the identified activity and a threshold. The device can provide a notification to at least one intermediary device of the set to configure the at least one intermediary device to allow the activity or prevent the activity.

  • Patent number: 11343357
    Abstract: Systems and methods for autonomous program management include a device which may transmit data to a client in response to a first request from the client. The data may include a response to the first request and a copy of data available to the device corresponding to the first request or the client. The device may receive a second request including the copy of data from the client. The device may determine that the second request is from an autonomous program rather than a user of the client based on the copy of data from the second request. The device may block at least one subsequent request from the client in response to the determination that the second request is from an autonomous program.
