Due to several recent security concerns with Zoom meetings, we want to present some options to secure your meeting and mitigate these problems. One concern is “Zoombombing”. Zoombombing is when an uninvited attendee breaks into and disrupts your meeting, often sharing inappropriate content. This is a new trend that is becoming more prevalent with the increased use of Zoom and we want to provide some tips on how you can make your meeting more secure.
By default, we have screen sharing for all participants turned on. You can adjust your account so that all meetings default to Host Only sharing or you can do this on a per meeting basis.
Note: If you are scheduling public meetings, where the link will be advertised, it is highly recommended you change this setting to Host Only sharing.
Change Screen Sharing to Host Only
