How to Prevent Zoom Bombing

"Video conferencing app Zoom has had a meteoric rise in users due to the coronavirus outbreak, and with that rise in users has come security woes and an annoying new trend known as "Zoom bombing." Zoom bombing is, in essence, crashing a digital meeting and doing things like screaming obscenities, broadcasting pornography, and otherwise interrupting people's attempts to talk to coworkers, family, and friends. ...

Even with all of Zoom's security issues, it can't be blamed entirely for the Zoom bombing trend--internet trolls have been using publicly posted meeting links, guessing meeting IDs, and using personal meeting IDs posted online as ways to join meetings uninvited.

Zoom has built-in tools that can prevent Zoom bombings from occurring, and they're all remarkably easy to enable when creating a new meeting. These steps won't completely eliminate the chance that a bad actor crashes your Zoom call, but they'll go a long way toward making sure the host has control over what each and every person can do in their meeting."
