1. A data processing device, comprising:

  • a memory storing instructions; and

    a processor configured to execute the instructions to provide a domain name server (DNS) proxy module that intercepts DNS requests sent by a client and, for each intercepted DNS request, when the intercepted DNS request corresponds to a secure server, determines whether the client is authorized to access the secure server and, if so, automatically initiates an encrypted channel that enables communications of at least one of audio data or video data between the client and the secure server.
