A Note on "Zoom-Bombing"

Published March 24, 2020

Dear Faculty, Students, and Staff,

As we are leveraging Zoom for an alternative method of instruction, a cybersecurity attack called “Zoom-bombing” has come to our attention, in which the bad guys crash Zoom meetings to cause disruption and security concerns.

The following measures will help keep your Zoom meeting private and secure and thereby reduce the chance of unwanted attendees and disruptions.

  • Use your CSULB Single Sign-On Zoom chiclet to log in to your Zoom account. 
  • Keep your Zoom meeting private and secure, rather than hosting the meeting as a public event on social media. 
  • Avoid hosting large meetings or “public” meetings using your Personal Meeting ID (PMI).
  • Lock your Zoom meeting once it has started and all your expected participants have joined.
  • When scheduling a meeting, under Meeting Options, select Require Meeting Password.
  • Enable the Waiting Room Feature which allows the host to control when each participant joins the meeting.
  • If you find yourself with a disruptive participant in your meeting, you can remove them. Click on Participants at the bottom of your Zoom window then select More and Remove for the participant that you want to eject from the meeting.

For additional help with Zoom, please refer to the campus Zoom service page or email Zoom@csulb.edu.  Zoom has also released guidance for users who want to protect themselves from Zoom-bombing - How to Keep the Party Crashers from Crashing Your Zoom Event.
