What is ‘zoom bombing?’ it is basically done by someone who accesses a meeting and then shares inappropriate material.
One way of preventing this happening is by amending the settings in zoom so that only the host oo co-host can screen share. This is done by doing the following:
Go to ‘Settings’ in the left hand column
Scroll down to the bottom until you come to ‘screen sharing’
Change the settings to ‘host’ or ‘co-host’ rather than ‘all participants’.
