Keep Zoom application updated!

  • Your work computer: Zoom is automatically updated during normal working situation on campus. When you are working remotely, you must turn on your computer's Virtual Private Network (VPN) (read instructions), and check updates in Window's Software Center or MacBook's Managed Software Center.
  • Home computers and mobile devices: use Zoom application's Check for updates functionality.

Safe Zoom video meetings

There have been reports in various media and social media that some Zoom video meetings have received uninvited guests or have been disrupted by inappropriate presentation or video material. This is a common risk in video meeting services if the meeting is organized as an open meeting and can be attended by anyone with invite link. When you create a video meeting, you can restrict access to the meeting using, for example, a password or login requirements, and specify whether to allow all or only registered users to join. During a video meeting, Zoom also provides features to control and prevent intentional or unintentional interference from participants. The more participants there are in your Zoom meeting, and the more publicly you share the join link, the more you should check out the following tips.

Passcode or waiting room recommended in all Zoom meetings

Zoom does not require passcode in meetings and webinars, but it is recommended. Passcode on enabled by default in new meetings. If you remove passcode, please enable waiting room.

Changes to default Zoom meeting settings 15.4.2020

The following changes were made on 15.4.2020 affecting mainly the new scheduled meetings after this date: 

  • participants are able to join meeting only when the host is present (Allow participants to join anytime setting in Zoom meeting's Advanced options is not selected)
  • meeting passcode is set by default (Passcode in Zoom meeting's security settings)
  • each participant's microphone is muted when joining the meeting (Mute participants upon entry setting in Zoom meeting's Advanced options)
  • private chats between participants are disabled during meetings (Private chat setting in host's Zoom portal Settings page, affects all meetings)
  • file transfers are forbidden in meeting chats

Before the meeting

With following tips you can avoid unwanted attendees and their misbehavior in your meetings.

 1. Use randomly generated meeting ID. You should not use your personal meeting ID in public or big meetings. Instead, choose a randomly generated ID for meetings when creating a new event.

2. Avoid sharing the meeting join link and ID publicly on web pages and social media. In public events, prefer registration form, either separate one like Office 365 Forms or Zoom's own registration method for non-recurring meetings in Zoom web portal. See Registration for Meetings  

3. Use waiting rooms. The Waiting Room feature is a way to screen participants before they are allowed to enter a meeting. While legitimately useful for purposes including interviews or virtual office hours, this also gives you as host greater control over session security.
Note: With newest Zoom application you can enable waiting room also during the meeting. 

4. Authenticate users. If all participants are from Tampere Universities, you can choose to only allow signed-in users to participate. (Only authenticated users can join setting in Zoom meeting's Advanced options)

5. Meeting participants can annotate on a shared screen as a viewer or the one that started sharing your screen. You can block this during a video meeting via the Zoom security menu during screen sharing by disabling allow all participants to: annotate on shared content or from more menu by selecting disable annotation for others . If you want to prevent this in advance, you can turn off the annotation feature in your Zoom user account settings. See also: Using annotation tools on a shared screen or whiteboard
