Assessment Title
Rule Text
The Session Border Controller (SBC) must be configured to manage IP port pinholes for the SRTP/SRTCP bearer streams based on the information in the SIP and AS-SIP messages.
Description
Discussion Text
The function of the SBC is to manage SIP and AS-SIP signaling messages. The SBC also manages the SRTP/SRTCP bearer streams. The DISN IPVS PMO has determined that the SBC will pass the negotiated and encrypted SRTP/SRTCP bearer streams without decryption and inspection. This is because doing so will not provide a significant security benefit but would cause a significant delay with a resulting decrease in the quality of the communications.
Encoded audio and video is difficult to impossible to determine if an attack is being perpetrated or if sensitive information is being improperly disclosed without reconstituting the analog audio and video signals and having a person listen and watch each communication. Due to the volume of communications, to do so would be nearly impossible.
