Securing Zoom

Zoom is a flexible and useful platform for conducting remote instruction. It is important to note that there are some settings to consider when using Zoom for your class. This information highlights settings that help mitigate the risk of privacy concerns, uninvited participants, and unauthorized distribution of your class content. Changing some of these settings may not take effect for already scheduled meetings, and so you’ll want to test these before conducting class via Zoom.

Settings for Zoom can be found here: Zoom recording settings and Zoom meeting settings.

Important: on March 25, 2020, at 10:00 pm, an additional authentication option was added to restrict meeting access to only those participants logged into UNC Zoom. Before this change, anyone with a Zoom account, including external users, with whom a meeting ID or link had been shared, could potentially join authenticated Zoom meetings. To activate this option, you will need to edit your profile’s Zoom meeting settings, and turn on Only authenticated users can join Zoom meetings. The default option is now UNC Zoom only. Any meetings already scheduled will need to be edited:

  1. Turn the authentication settings on in your profile meeting settings: https://unc.zoom.us/profile/setting
  2. Go to your list of scheduled meetings: https://unc.zoom.us/meeting?type=upcoming
  3. Under the Topic column, click topic name for your meeting.
  4. On the Meeting Information page, scroll down to Edit this Meeting.
  5. Scroll to Meeting Options, and check Only authenticated users can join.
  6. UNC-CH only will be selected by default, provided you’ve completed step 1.
  7. Click Save.
  8. Return to your list of scheduled meetings, and repeat steps 3-7 for each additional meeting.

Privacy settings:

Feature Setting Information
Record active speaker with shared screen. YES Students who have their video on during the session would appear on-screen only if they are unmuted.
Record gallery view with shared screen. NO The gallery view shows all participants in a grid format. Turning this off means that the gallery view won’t be recorded and only the active speaker will.
Recording consent. NO Students who do not consent will not be allowed to participate in the meeting.
Only authenticated users can access the recording. YES Enabling this option requires people to enter their UNC Onyen and password to access the file. Anyone with a UNC Onyen (even outside of your class) can access the content. Check that you have enabled this setting in your profile’s Zoom meeting settings.
Display participants’ names in the recording. NO Setting this feature to off will ensure that participants’ names are not made a part of the recording.
Save chat messages from the meeting/webinar. NO Enabling this option allows viewers to see participants’ names. With this option disabled, Zoom will automatically download a.txtfile of the chat transcript to your
local computer’s Documents/Zoom folder. Note that this transcript also includes participants’ names.

Uninvited participants (sometimes called Zoombombing):

Feature Setting Information
Require meeting password YES When scheduling a meeting or editing a pre-existing meeting, you have the option of requiring participants to enter a password that you assign. Useful for thwarting “Zoombombers” who try random combinations of numbers to access meetings; less useful for when meeting access information is shared with those outside of the class.
Require password for participants joining by phone YES You can enable this option in your profile’s Zoom meeting settings. A numeric password will be required for participants joining by phone if your meeting has a password. For meetings with an alphanumeric password, a numeric version will be generated.
Only authenticated users can join YES When scheduling a meeting, you have the option of requiring participants to enter their UNC Onyen and password before entering the meeting. Check that you have enabled this setting in your profile’s Zoom meeting settings. NOTE: Participants who are calling in will not be prompted to authenticate. To prevent unwanted callers from joining the meeting, also enable Waiting Room, Guest Participants Only (see below).
Waiting Room YES Select Guest Participants Only. (Option only found in your profile’s Zoom meeting settings. This will place anyone calling into the meeting into the Waiting Room. If you have not set the meeting so that only authenticated users can join, anyone with a non-UNC Zoom account will also be placed into the waiting room. All other participants will bypass the waiting room and be allowed to enter the meeting. Note: On March 31, Zoom activated this setting by default, including for existing meetings.
Allow Removed Participants to Rejoin NO Disabling this setting will prevent uninvited participants to come back into the meeting.

Unauthorized dissemination of content:

Feature Setting Information
Only authenticated users can view cloud recordings YES When sharing a Zoom-recorded class session via Zooms cloud service, enabling this will restrict access to those with a UNC Onyen.
Viewers can download NO Viewers will be able to watch a stream of the recording, but not download a copy.  This feature is available as an option when sharing your recordings.
UNC Honor Code Advise your students that the content is intended only for the class and that there are copyright and intellectual property stipulations on the content. NOTE: This is only helpful while they remain a UNC student.
