  • Patent number: 9083737
    Abstract: Mitigating threats in a network includes receiving a message at a network device. The message includes device-independent parameters generated in response to a threat. The network device converts the parameters into one or more device-specific operations and then performs the operations to mitigate the threat.
    Type: Grant

  • Patent number: 9077739
    Abstract: In one embodiment, a system can comprise an interface that receives data related to a communication session and a messaging security device component that evaluates the data and enables a security measure for preventative monitoring of a threat based on the evaluation, the security measure can be universally applied to two or more messaging formats.

  • Patent number: 8156554
    Abstract: A method and system for verifying identification of an electronic mail message. An electronic mail message including a signature and a key is received, the signature identifying a domain from which the electronic mail message originated and the key for verifying the signature. A key registration server of the domain is accessed to verify the key. The key registration server provides for verifying that a key used to sign an electronic mail message is valid and that the sender is authorized by the domain to send the electronic mail message from the return address.

  • Patent number: 8090940
    Abstract: An electronic message is accessed. The message comprises a number of headers and a signature comprising a digital signature and a version of the headers. The message is verified based on analysis of the version of the headers and the digital signature. The version of the headers is compared with the headers and a policy is applied based on results of the comparison to determine further processing of the electronic message.

  • Patent number: 6445697
    Abstract: An Internet telephony gateway and method for operating a gateway are disclosed. The gateway is designed with a port to support a predefined maximum number of audio data channels. The gateway contains sufficient processing throughput to operate a first, high quality audio codec on a subset of the channels. However, this throughput is sufficient to operate a second, lower quality audio codec on a greater number of the channels, preferably all of them. The first and second codecs are designed to produce compressed audio data streams that are interoperably decompressable. In operation, the gateway host processor assigns new calls to either the first or second codec, depending on the current traffic being handled by the gateway. If new calls would result in the gateway's processing throughput being exceeded, the host processor may reassign a channel from the first codec to the second codec in order to create processing headroom for the addition of a new channel.
