  • Patent number: 8813126
    Abstract: An advertisement storage and filtering system for selectively identifying targeted advertisements to be stored in the memory of the STB. This storing of the selected advertisements can be accomplished in a number of ways. In one embodiment, the advertisements, in real-time and as they are received at the STB, are processed by the STB and only those advertisements with the appropriate characteristics are stored on the hard drive (HD). This may require some buffering of the advertisements in the STB memory as the STB processes and determines whether or not to store the advertisement. The information required to determine whether or not to store the advertisement could also be sent in advance, e.g., as a data service in an advertisement channel. Alternatively, the STB may store incoming advertisements in a memory temporarily and subsequently determine whether or not to retain the stored advertisements.

  • Patent number: 8250642
    Abstract: Computer system, method and program for managing a firewall. First program instructions identify a first rule of the firewall. The first rule specifies a permitted message flow through the firewall to or from an IP address of a computer. The computer resides on a network. Second program instructions identify a second rule of the firewall. The second rule specifies a permitted message flow through the firewall to or from an IP address corresponding to the network. Message flows through the firewall to all computers on the network are permitted pursuant to the second rule. Third program instructions delete the first rule from the firewall based on the identification of the second rule and the computer residing on the network. Other program instructions identify and delete stale rules which are not needed. Other program instructions automatically identify rules for a new server added to a cluster.

  • Patent number: 8180874
    Abstract: A method for defending against MAC table overflow attacks comprises a plurality of operations. An operation is performed for determining whether each one of a plurality of MAC addresses within a MAC table has one-way traffic or two-way traffic corresponding thereto. Thereafter, operations are performed for designating each MAC address having two-way traffic corresponding thereto as a first category of MAC address and for designating each MAC address having one-way traffic corresponding thereto as a second category of MAC address. In response to the number of the MAC addresses designated as the second category of MAC address exceeding a prescribed threshold value, an operation is performed for causing a timeout value of at least a portion of the MAC addresses designated as the second category of MAC address to be less than a timeout value of the MAC addresses designated as the first category of MAC address.

  • Patent number: 8126148
    Abstract: The invention is a new protocol for securing the communication link between the Home Agent and the Mobile Node. A cipher key and an integrity key are generated at a home AAA server and are also generated independently at the Mobile Node. The two keys generated at the home AAA server are transmitted to the Home Agent to secure information packets transmitted between the Mobile Node and the Home Agent. The cipher key and integrity key are used to establish a security association used for information packet transmissions. The cipher key is used to encrypt the information packets, and the integrity key is used to ensure that the contents of the encrypted message are not altered.

  • Patent number: 8121295
    Abstract: To manage playout of digital media by a media player, a wireless communication device (WCD) will include partitioned data storage including discrete partitions having distributor-modules corresponding with various media distributors, and including a digital rights management (DRM) controller. When the media player seeks to play media, it will request a DRM key from the WCD. The DRM controller may then identify the appropriate distributor-module and request the key from the distributor-module. If the distributor-module possesses the key, it will return it for transmission to the media player. Otherwise, the distributor-module may engage in secure communication with a provisioning system to obtain the DRM key and may then return the key. Upon receipt of the key, the media player may then play the media.
