Best Practices to Secure Meetings


Zoom Meetings and Webinar tools are available to the UNC Asheville community to allow the continuation of collaborative, inquiry based learning environments. While Zoom Meetings is intended for small group collaborative sessions, and Zoom Webinar for large group, less interactive sessions, either may be exposed to unwanted interruptions that can decrease the productive environment. It is important to keep the software updated to prevent Zoom Meeting issues. The most recent Zoom Desktop Client or Mobile application can be downloaded here.

Zoom Meeting Functions for Hosts

The meeting may be configured, or edited to enable, for use of:

  • Disable video and or audio:  This will block a participant’s ability to distract others visually or make audible but also limits participation and monitoring of participants.
  • Waiting Rooms:  All participants attempting to join the meeting session are placed into a virtual waiting room, the faculty member then admits them individually or all at once.
  • Control Screen Sharing:  Participant use of Screen Sharing is controlled and enabled by the faculty member. The faculty member can allow participants to share as needed.
  • Require participant use of a discrete passwordCreate a password and share so only students and expected subject matter experts may access the virtual meeting. This would prevent anyone randomly guessing Zoom meeting IDs from joining. Note: Passwords are not available to previously scheduled meetings. Schedule a new meeting in order to add a password.
  • Join before host:  Disabling this will ensure that faculty are the first individual in the meeting room, and can admit participants to join if waiting rooms are enabled.
  • Allow only authenticated users:  This requires the participant to use a Zoom account.  This prevents anonymous guests from joining your meeting.  Please communicate with participants that they need to create a free Zoom account before joining the meeting. 

At anytime during a meeting faculty may:

  • Lock the meeting:  Allow a few minutes for late arrivals and no one else may join the virtual meeting once it is locked.  
  • Lock down the chat function:  The chat function can be disabled entirely, or only the private chat functionality.
  • Remove a participant:  Individual participants may be removed from a virtual meeting at any time at the discretion of the host for any reason.
