A company has recently implemented a video conference solution that uses the H.323 protocol.
The security engineer is asked to make recommendations on how to secure video conferences to
protect confidentiality. Which of the following should the security engineer recommend?
A.
Implement H.235 extensions with DES to secure the audio and video transport.
B.
Recommend moving to SIP and RTP as those protocols are inherently secure.
C.
Recommend implementing G.711 for the audio channel and H.264 for the video.
D.
Encapsulate the audio channel in the G.711 codec rather than the unsecured Speex.
