Securing Zoom

To better serve our community and the use of Zoom at Western defaults have been changed for some of the optional settings for Zoom meetings. These defaulted settings can be turned on or off by the host (typically, the creator of a meeting), on a per-session basis, for classes or meetings where such interactions are necessary.

From the Security section:

This will be turned ON by default, so that a passcode will be generated when scheduling meetings, and participants will be required to enter it in order to join a session.

To adjust your Zoom Account settings, sign into Zoom and from the left navigation menu select Settings and navigate to Security.

The settings screen contains a list of defaults, which you can adjust to customize your meeting settings.

This option, which encrypts the password in the invite link, will be turned off by default. The passcode should be sent separately from communications with the link to the meeting.

To adjust your Zoom Account settings, sign into Zoom and from the left navigation menu select Settings.

The waiting room will be turned on by default, so that participants will be unable to join the meeting until admitted by the host.

To adjust your Zoom Account settings, sign into Zoom and from the left navigation menu select Settings and navigate to Security.

The settings screen contains a list of defaults, which you can adjust to customize your meeting settings.

NOTE: This option will automatically disable the setting to allow participants to join the meeting before the host.

This option will be turn on by default, so that participants will require to use a legitimate @uwo.ca or @ivey.ca account to access meetings.

When joining a meeting participants will need to select 'Sign In with SSO' option which will prompt for the Western UserID and Password.

It is understood that some meetings will require guest speakers or need to be configured in such a way that this setting cannot be used.

You can turn off 'Only authenticated users can join meetings option' by adjusting your Zoom Account settings, or unchecking the option while scheduling a meeting.

To adjust your Zoom Account settings, sign into Zoom and from the left navigation menu select Settings and navigate to Security.

To uncheck the option while schedule a meeting: 

Note: this option is called 'Only authenticated can join' when you schedule a meeting from Zoom app. 

  

Allowing Authentication Exceptions

If you have individuals who are not part of your authentication requirement, you can add them to the “Authentication Exception” list. This is for inviting guest lecturers or participants, without reducing the security of your meeting.

Adding authentication exceptions (Hosts/users)  

  • Sign in to the Zoom web portal.  
  • Schedule a meeting or webinar. 
  • Under Meeting Options or Webinar Options, make sure  Required  authentication to join is enabled.   
  • Under Authentication Exception, click Add.  


  • Enter the guest participant's name and email address.  
  • Click Add Participant to add more exceptions.  
  • Click Save.
  • Participant will receive a unique link to the meeting at their email address. 

End-to-end (E2EE) encryption adds a layer of security for meetings where there is a need for enhanced privacy, or the data protection for your meetings.

When a host enables E2EE in a meeting, these features are disabled

  • Join before host
  • Cloud recording
  • Live streaming
  • Live transcription
  • Breakout Rooms
  • Polling
  • Meeting reactions
  • 1:1 private chats
  • Users will not be able to join by telephone, SIP/H.323 devices, on-premise configurations, the Zoom web client, third-party clients leveraging the Zoom SDK, or Lync/Skype clients, as these endpoints cannot be encrypted end to end. 

All participants must join a meeting from a Zoom desktop client or mobile app. Joining from a web browser is not permitted.

  • Zoom desktop client
    • Windows: 5.4.0 or higher
    • macOS: 5.4.0 or higher
    • Linux: 5.4.0 or higher
  • Zoom mobile app
    • Android: 5.4.0 or higher
    • iOS: 5.4.0 or higher

How does it work?

In standard Zoom meetings, the Zoom servers encrypt transmission of the video and audio. If a meeting host uses E2EE, the keys for each Zoom meeting are generated by participants’ machines, not by Zoom’s servers. 

To enable E2EE for all your meetings (not recommended):
  • Go to westernu.zoom.us and sign in
  • Click Settings, then scroll down to Allow use of end-to-end encryption, click the toggle to enable it
  • Under Default encryption type, check End-to-end encryption
  • Click Save 
To enable E2EE for a meeting:
  • Go to westernu.zoom.us and sign in
  • Click Settings, then scroll down to Allow use of end-to-end encryptionclick the toggle to enable it (defults to Enhanced encryption)
  • Click Meetings, then click Schedule a Meeting 
  • Under Encryption, select End-to-end encryption 

Note : Because of the limitations of E2EE, Zoom recommends using Enhanced encryption as the default encryption type and using end-to-end encryption for meetings where additional protection is required.

Using E2EE for meetings:

  • Once you’ve joined the meeting, check for the green shield icon  in the upper left corner of the meeting window
  • The meeting host can also read the security code aloud and the participants can verify that their codes match.
