Authenticate Video Calls and Manage Settings

Ensure all video call actions and settings changes are verified with authentication and authorisation.

Plain language

This control ensures that all the actions you take on a video call, like starting a call or changing settings, are done by someone who's been verified. It's like double-checking that the person making changes is really supposed to be doing it. If you skip this, anyone might make unapproved changes or eavesdrop, potentially exposing sensitive conversations or causing disruptions.

Why it matters

If video call setup and settings changes aren’t authenticated and authorised, attackers can join calls, change meeting options, or disrupt sessions, exposing sensitive discussions.

Operational notes

Enforce authentication/authorisation for call setup and settings changes; review meeting and admin logs and alert on failed logins or unauthorised attempts to change call settings.
