A multinational organization is implementing a new video conferencing solution for their executive team to discuss sensitive business strategies. The security architect is concerned about unauthorized access to these meetings. Which security control would be MOST effective in preventing unauthorized participants from joining these confidential video conferences?
Implement multi-factor authentication for meeting participants
Multi-factor authentication (MFA) provides the strongest security for video conferencing access by requiring users to verify their identity through multiple verification methods. By combining something the user knows (password), something they have (mobile device for one-time codes), and potentially something they are (biometrics), MFA significantly reduces the risk of unauthorized access even if credentials are compromised.
While meeting passwords provide basic protection, they can be easily shared or leaked. Encrypted connections protect data in transit but don't verify participant identity. Meeting waiting rooms are helpful for manual verification but rely on the host's judgment and attention, making them less reliable than systematic MFA verification, especially for highly sensitive executive meetings.
