Better Zoom and Google Meet Security

Posted on November 15th, 2021 by

There are a number of precautions you can take to ensure the privacy and security of your Zoom and Google Meet virtual meetings.

  1. Don’t publicize your Zoom or Google Meet links where others may view and access them. Disseminate your links securely through direct invitations, or by using documents and web pages that require authentication.
  2. Avoid using Zoom’s personal rooms except with people you meet with regularly. These persistent spaces, once discovered, can be difficult to keep secure.
  3. Zoom can be set up to restrict access to Gustavus users only (see instructions below). This one requirement offers substantial peace of mind by offering assurance that attendees are authenticated members of the community.
  4. Google Meet will not allow anonymous users to join virtual meetings, and those without invites need host approval to join. Using Google Calendar to schedule meetings and invite potential attendees can eliminate a lot of security concerns.

For both Zoom and Google Meet, we recommend strictly enforcing the use of authenticated Gustavus accounts. If an attendee has difficulty accessing your virtual meeting, try to troubleshoot their issue over Google Chat, or by phone. If you don’t recognize them, the best policy is to decline their attempts to join your session.
