  • Patent number: 10419398
    Abstract: A method and apparatus for resource locator identifier rewrite have been presented. A security device receives from a resource host over a non-secure hypertext transfer protocol (HTTP) session a response to a request received from a client over a secure HTTP session. The response includes a uniform resource locator (URL) that is supposed to be for a resource host, but the URL does not designate a secure resource access protocol and the resource host requires the secure resource access protocol. The URL is located in the response and modified to designate the secure resource access protocol. After modification, the response is transmitted via the secure resource access protocol session to the client.

  • Patent number: 8074259
    Abstract: An authentication mark-up data of multiple local area networks is disclosed. In one embodiment of a system, the system includes a wide area network, an update device coupled to the wide area network, and any number of gateway devices coupled to the wide area network. Each of the gateway devices is associated with a separate local area network. Each of the plurality of gateway devices automatically provide an authentication page stored in the update device based upon a data provided to the update device. In addition, the authentication page is the same for at least some of the plurality of gateway devices, according to the one embodiment.

  • Patent number: 7996894
    Abstract: A method is disclosed for providing security to a client-to-client communication. The method includes authenticating a first client and a second client with an access point device, transmitting the packet to the security device and modifying a destination media access control (MAC) address of a packet from the first client to a MAC address of a security device for a first network. The packet contains a destination internet protocol (IP) address of the second client. The access point device and the first and second clients belong to the first network. The security device is located between the first network and a second network.

  • Patent number: 7412539
    Abstract: A method for resource locator identifier rewrite in which a network security proxy insures that a resource locator identifier of a response indicates a resource access protocol that should govern a corresponding request. A security device receives from a resource host over a non-secure hypertext transfer protocol (HTTP) session a response to a request received from a client over a secure HTTP session. The response includes a uniform resource locator (URL) that is supposed to be for a resource host, but the URL does not designate a secure resource access protocol and the resource host requires the secure resource access protocol. The URL is located in the response and modified to designate the secure resource access protocol. After modification, the response is transmitted via the secure resource access protocol session to the client.
