1. Configure a Meeting ID and Password
Setting a meeting ID and password seems trivial but it’s far from it. Attackers and disrupters can guess or enumerate meeting ids using a process called “war dialing.” zWarDial is a tool used to identify the phone numbers that can successfully make a connection to a computer modem or in this case a Zoom meeting. The use of zWarDial, makes it important to set a password to help stop uninvited guests from performing a “Zoom Bombing”, in which uninvited guests introduce inappropriate content to your conference call.Image

2. Enable Waiting Room
Zoom has a feature called “Waiting Room” which allows the host to control when a participant joins the meeting. As the host, you can admit attendees one by one or hold all attendees in the waiting room and admit them all at once. This option allows hosts to be selective and allow entrance for attendees they’re expecting.Image

3. Disable “Join before host”
Disabling “join before host” will prevent attendees from entering a Zoom meeting before the host. This is important because with this setting enabled the first attendee who joins the meeting will automatically be made the host and have full control over the meeting.Image

4. Enable “Mute participants on entry”
This function will allow the host to have all participants automatically muted upon entry. With the exception of webinars, participants will be able to unmute themselves in the meeting. Having meeting attendees muted as they join will reduce noise disruption.Image

5. Enable Screen Share to “Host Only”
Preventing others from screen sharing unless given permission will keep the meeting orderly and prevent unexpected users from disrupting the meeting via screen sharing.Image

6. Disable “Allow Removed Participants to Join”
If there is a disruptive attendee or an uninvited guest that connects and the hosts removes them, disabling this feature will ensure that they cannot continuously rejoin the meeting.Image

7. Disable “Allow File Transfer”
Malware can be shared via file transfers, so by disabling file transfer during a zoom meeting you will prevent any attendees from sharing potentially malicious files.Image

8. Keep your Zoom application up to date
Keeping your applications up to date ensures you have the newest features and security updates installed. This should apply to all your applications, not just Zoom.Image
