  • Patent number: 8726020
    Abstract: Automatically sending configuration information from a trusted network to a perimeter network. Master servers residing in the trusted network are adapted for administering a distributed directory service containing configuration information. Edge servers residing in the perimeter network are adapted for using a local directory service local to each edge server. Edge-connected bridgehead servers residing in the trusted network are adapted for replicating the configuration information from the trusted network to the perimeter network. Replicating the configuration information to the perimeter network by trusted servers acquiring leases on edge servers is also disclosed.
    Type: Grant

  • Patent number: 7693071
    Abstract: Systems and methods are described which provide enhanced stability, increased predictability, reduced transmission costs, and which conserve bandwidth in routing messages over computer networks. The systems and methods further include providing improved transmission of messages wherein the messages are transmitted to nodes closest to a target delivery node. If delivery is possible to a target node, the message transmission stops at the point of failure in the network, wherein delivery to the target node is accomplished at a later time or the message is returned to the sender.

  • Patent number: 7681074
    Abstract: Failover systems and methods for providing redundant backup of data transmitted over a network to provide transport high availability of electronic data. The present invention relates to creating redundant backup copies of electronic data as well as transmission of the backup copies over a network in the event of a failure of a network component.

  • Publication number: 20070106783
    Abstract: Multiple independent MTAs transmit messages such that if one of the MTAs fails, the other MTAs may continue to transmit messages. Multiple independent message stores are provided such that if one of the message stores fails, messages on the other message stores may continue to be transmitted. Multiple notification agents monitor the message stores for new messages and notify one of the MTAs when a new message is available for transmission.

  • Publication number: 20060212286
    Abstract: A workflow manager application transfers message data received from an originating device via a communication network to a target application for processing. A graphical user interface displays the received message data and allows the user to view and designate one or more target applications for processing the message data. The workflow manger application is responsive to user input to transfer message data to the designated one or more target applications for processing the message data. Alternatively, the workflow manager application analyzes received message data to identify one or more target applications, and transfers the message data to the identified one or more target applications for processing.

  • Publication number: 20060090195
    Abstract: The present invention allows for remotely and securely configuring settings for targeted devices within a network with multiple security-trust boundaries. Configuration information is encoded in messages that are digitally signed to ensure the integrity of the configuration information and sent in accordance with a standard messaging transport protocol. By utilizing an already existing port of the standard messaging transport protocol, e.g., SMTP, the number of open ports for configuration purposes is minimized. Further, example embodiments take advantage of hidden fields, i.e., machine readable fields that contain metadata that by default are not presented at a client user interface, for encoding the configuration or command/control information within the messages.

  • Publication number: 20060075099
    Abstract: The present invention utilizes honeypots, which are messaging system resources set up to attract unauthorized or illicit use thereof, for automatically identifying messages with malignant content. As messages are received at a honeypot, fingerprints of the messages are generated, which correspond to pattern information within the messages. These fingerprints are then used to determine a confidence level that messages received at a legitimate messaging service are malignant. Based on the confidence level, various actions (e.g., deleting the malignant content) may be executed.
