Zoom Bombing is where an unauthorized person enters your Zoom video conference to cause disruptions or to gain sensitive information. Many companies and schools have begun using video conferencing extensively and there’s been numerous news reports of “zoom bombing” problems.

What does this mean for an SMB or Schools?
- If you are the host of the meeting, make the meeting private, requiring a password or private link to join the conference call;
- When the meeting is made private, control access to the meeting by enabling the “waiting room” feature so you can manually let authorized people into the meeting; you would get a message similar to, “Bob Johnson would like to join the meeting” and would need to approve;
- Do a roll call and keep track of the amount of users that are supposed to be in the meeting, if you invited 8 users and there are 10 in the meeting, you may want to check out who the two (2) extra users are;
- Don’t share the meeting ID, password, or meeting link on a public platform, such as your website or related social media site;
- Once every authorized user has joined the meeting, lock the meeting so nobody else can join;
- Only allow the Conference Host to have control of screen sharing;
- Disable file-sharing so people aren’t flooded with content.
Specific Zoom Settings to Examine
The following are recommended settings for hardening your Zoom Meetings:

Links to Web Conferencing Solution Reviews
CyberHoot clients have been asking “should I switch to another Web Conferencing tool that is more secure?”. My response is, it depends. It’s now coming to light that other Web Meeting companies may have their own security challenges. For example, GoToMeeting.com allegedly has some cookie and privacy issues being reported about their website. Zoom may become the safest Web Meeting tool available due to the scrutiny it is facing today.
