How to prevent "Zoombombing"

What is "Zoombombing" ?

Zoombombing refers to the unwanted, disruptive intrusion, generally by Internet trolls into a video conference call. In a typical Zoombombing incident, a teleconferencing session is hijacked by the insertion of material that are lewdobsceneracist, or antisemitic in nature. (source: Wikipedia).  This is usually caused by unwanted or uninvited participants in your zoom meeting.

How to prevent it? A few quick steps you can achieve by make sure you have set up these configurations within your zoom settings.

1.  Make sure your Zoom App is up-to-date.

2. Use a unique ID and password for zoom conference and calls instead of using your assigned "Personal Meeting ID" or PMI.

When scheduling a meeting, in Meeting ID, choose "Generate Automatically" and "Require meeting password"

3. Turn on your Waiting Room setting

This makes anyone who wish to join the session to wait in the "Waiting Room" until authorized by the host.

4. Make sure Only the Hosts can share screen.

Don't worry, once it is locked, the host can still authorizing sharing for a specific participant during the meeting.

5.  Locked the meeting once it has started

Once everyone has joined the meeting and you aren't expect anyone else, you can lock the meeting from new participants. While the meeting is running, navigate to the bottom of the screen and click Participants. The Participants panel will open. At the bottom, choose More > Lock Meeting

6. Kick the Bad Participants Out

Sometimes, despite all effort, unwanted guest still got in.  As a host you can always kick them out.

To kick someone out: During the call, go to the Participants pane on the right. Hover over the name of the person you want to boot and when options appear, choose Remove.
