Abstract: A request to receive multicast data, associated with a multicast group, may be transmitted. The request may be transmitted via a tunnel. Group keys may be received in response to the request. The group keys may be based on the multicast group. An encapsulated packet may be received via another tunnel. The encapsulated packet may be processed, using the group keys, to obtain a multicast packet associated with the multicast data. The multicast packet may be forwarded to at least one multicast recipient.

Abstract: Secure tunneled multicast transmission and reception through a network is provided. A join request may be received from a second tunnel endpoint, the join request indicating a multicast group to be joined. Group keys may be transmitted to the second tunnel endpoint, where the group keys are based at least on the multicast group. A packet received at the first tunnel endpoint may be cryptographically processed to generate an encapsulated payload. A header may be appended to the encapsulated payload to form an encapsulated packet, wherein the header includes information associated with the second tunnel endpoint. A tunnel may be established between the first tunnel endpoint and the second tunnel endpoint based on the appended header. The encapsulated packet may be transmitted through the tunnel to the second tunnel endpoint. The second tunnel endpoint may receive the encapsulated packet. Cryptographic processing of the encapsulated packet may reveal the packet having a second header.

Abstract: Systems, apparatus, methods, and computer program products for multicast access control are provided to analyze incoming data based on a source zone and a destination zone of the incoming data. Appropriate access control rules are applied to incoming data based on the results of the analysis. Additional implementations of a multicast access control include using a proxy rendezvous point operable to function as a rendezvous point in place of a physical rendezvous point.

Abstract: A system and method for a network security system are provided. The method includes providing a master device and a backup device within a cluster of network security devices, providing the backup device with state information for the master device, detecting failure in the cluster and using the state information to recover from the failure.
