Zoom, How to protect your sessions

We strongly recommend that you take steps to protect your Zoom meetings. This will help prevent unwanted disruptions, commonly known as “Zoombombing.” This article provides direction on how to protect your Zoom lecture or meeting. Please weigh these options carefully to find the right balance between providing access and protection.

If you need to host public meetings where most participants are outside the University of Illinois System, we strongly recommend you use a Zoom webinar for your event. 

Please, do not post your Zoom meeting information (meeting ID, meeting link or passcode) to public forums or social media. Do not edit or disable the default meeting settings unless you are aware of, and accept the risk associated with doing so. Limit in-meeting participant features to only those participants require. If you must post information to a public forum or social media, and you require the interaction features of a Zoom meeting, require meeting registration and only publicly share registration links. If you require meeting registration, verify and manually approve each registrant. Utilize meeting authentication and the waiting room to block unwanted guests from joining.  More information about protecting your Zoom session can be found below.

If you have any questions or require assistance with your event, please reach out to the Technology Services Help Desk by creating a ticket at help.uillinois.edu, or by calling 217-244-7000, or emailing consult@illinois.edu.

All Zoom disruptions should be promptly reported to the Technology Services Privacy and Security team at: security@illinois.edu

Accessing your Zoom Meeting Settings

Meeting Setup Options

The Waiting Room feature in Zoom allows you to control when a participant joins the meeting. You can set up the Waiting Room so that only un-authenticated UIUC Zoom or participants outside of the UIUC Zoom account are placed there.  Please read below on how to customize your waiting room profile.  By default, the host or co-host must admit guests from the waiting room into the meeting.

Editing the Waiting Room Options


Zoom waiting room setting found within your Zoom meeting settings.  This should be the first setting listed.

You can decide in advance who is placed in your meeting's waiting room using your illinois.zoom.us settings. We strongly recommend you consider your audience and the potential security risks when choosing the options below. 

  1. Access your settings using the instructions above, and find the Waiting Room setting near the top of the Security subsection.
  2. Click Edit Options
  3. Configure who should go in the waiting room based on your attendees.
    • Everyone: All participants joining your meeting will be admitted to the waiting room.
    • Users not in your account: Only participants who are not on your Zoom account or are not logged in will be admitted to the waiting room. If not logged in, they will have an option to log in.
    • Users who are not in your account and not part of your approved domains: Users who are on your account or logged in to a Zoom account at the domains you list will bypass the Waiting Room. After selecting this option, enter the domain(s), separating multiple domains by a comma.
      Note: If "Users not in your account" or "Users who are not in your account and not part of your approved domains" is selected, you can allow those users who bypassed the waiting room to admit participants if the host is not in the meeting.
  4. Determine who can admit participants from the waiting room.  For public events it is strongly recommended to set to Host and co-host only.

Applying the Waiting Room to your Meeting

If you follow the steps above to turn on the waiting room in your Zoom profile settings at: illinois.zoom.us/profile/setting the Waiting Roomwill be applied to all new meetings by default. Otherwise, you will need to apply the Waiting Room manually when scheduling new meetings.

Follow the steps below to apply the Waiting Room to your meeting


Zoom waiting room setting found within your Zoom meeting settings.  This should be the first setting listed.
  1. Schedule a Zoom meeting as you normally would.
  2. Find the Security subsection
  3. Check the box next to the Waiting Room

For additional protection, we strongly recommend you use authentication to limit access to a Zoom event. .

Please refer to: Zoom, Using authentication to limit access to your virtual event for more information. 

There are six separate meeting passcode settings.  These are enabled, and locked on by default.  All UIUC Zoom sessions require a passcode.  Please review these settings; be aware of their scope and how they work.

Password

This setting can be used to get more information about a participant before they attempt to join the meeting. You can choose to automatically or manually admit registered participants. We strongly recommend manually approving registrants.

If someone who registers should not be there, you can deny their registration request. If meeting creators determine an approved registrant should no longer have access, they can revoke their registration

For more information about Zoom's registration tool, please visit Zoom Support:

Additional Recommended Options

The following settings can also be applied to prevent someone from taking over your lecture or meeting. These settings will apply to previously scheduled sessions. Please consider how you are using Zoom before adjusting these settings. For example, disabling screen sharing will make it harder for participants to share content in an interactive class or meeting.

Joining participants can be muted automatically to prevent unwanted noise or distractions.

We strongly recommend this setting is enabled for public events

The setting for mute all participants when they join a meeting can be found in the Schedule Meeting subsection at illinois.zoom.us/profile/setting

Mute

You can find and confirm this setting has been applied to your meeting when scheduling. Mute participants upon entry can be found in the Meeting Options

Meeting creators can set screen sharing to Host Only to prevent participants from taking over the screen during a meeting. During a meeting, Hosts can still allow users to Screen Share by either promoting them to co-host, checking Allow participants to: Share Screen in the in-meeting Security Tab or by using the Advanced Sharing Options during the meeting. Note: promoting individual users to co-host may give them more authority than you wish. Using the Security Tab or Advanced Sharing Options will allow all participants to share. Please weigh these options and choose what best protects your meeting

The host role is required to both promote a participant to co-host or alter the screen sharing options in-meeting.

By default, Screen Sharing is enabled and set to Host Only for UIUC Zoom accounts.Your default screen sharing setting can be in the In Meeting (Basic) section in your Zoom Profile Settings
