Best Practices for Securing Zoom Meetings

Zoom offers several features which can enhance the security of your Zoom meetings or classes.  When using it for public events, please follow guidelines immediately below to prevent disruptions such as “Zoom-bombing”. Examples of public Zoom events would be meetings and webinars that CUIMC markets and makes available for external attendees to attend.

For public meetings:

  1. A moderator should be assigned to remove disruptive attendees
  2. Join before host should be turned OFF
  3. Mute participants upon entry should be turned ON

 For public meetings and for webinars:

  1. Password protection is required 
  2. The ability for participants to screen share should be set to Only Host – panelists will still be able to share if they are made co-hosts during webinars
  3. Upon scheduling these webinars, please require registration as it will allow the webinar organizer to vet each external registrant to confirm valid name and email addresses
  4. These settings should be turned OFF
    1. File transfer
    2. Annotation 
    3. Allow removed participants to rejoin 
    4. Chat

Following are detailed steps for setting various security features in Zoom.

Using Passcode Protection

At the Medical Center, all meetings and webinars require the use of a passcode to ensure that no uninvited guests can gain entry.

  1. Sign in to Zoom and select Meetings from the menu on the left side of the page.
  2. Select the meeting that needs a Passcode and click the Edit button that appears.

  3. Scroll down to the Security section of the meeting's details and check the box next to Passcode. Zoom will add a randomly generated passcode in the field, or you can type over it to choose your own.

Disable Allow Participants to Join Anytime

Zoom provides the option to control whether participants will be allowed to join before the host, i.e. anytime.

Using the Waiting Room Feature

The Waiting Room feature allows hosts to enhance privacy by keeping participants from one meeting separate from the next. This feature can be enabled by default at the account level or enabled on a per-meeting basis. See Zoom's Waiting Room page for more information.
