City council chambers use cloud collaboration rooms and softphones with open dial-in numbers and weak meeting locks. Which practice best secures voice, video, and collaboration channels?
Select an answer to reveal the explanation.
Short Explanation
Open dial-ins are like leaving the council chamber door propped with a brick—anyone can wander in and listen or heckle. Lock the meeting, authenticate who joins, and keep the session encrypted.
Full Explanation
Secure voice and video collaboration requires confidentiality and controlled admission: encrypted channels, authenticated participants, and protections against open dial-in abuse such as locks, lobbies, and restricted conference IDs. Public standing numbers and disabled encryption increase eavesdropping and disruption risk. Collaboration systems must not be bridged into unrelated sensitive networks such as OT.
