Zoom can be insecure if the meetings aren’t setup properly, below are some recommendations from the web on resolving zoom security issues:
There are some easy settings you can change before your Zoom meeting begins that will allow you to reduce the likelihood of intrusion by uninvited guests, and generally bolster your privacy overall.
1. Don’t use your Personal Meeting ID for the meeting. Instead, use a per-meeting ID, exclusive to a single meeting. Zoom’s support page offers a video walk-through on how to generate a random meeting ID for extra security.
2. Enable the “Waiting Room” feature so that you can see who is attempting to join the meeting before allowing them access. Like many other privacy functions, a skilful disrupter can sometimes bypass this control, but it helps to put another hurdle in their route to chaos.
Zoom offers a support article here as well. To enable the Waiting Room feature, go to Account Management > Account Settings. Click on Meeting, then click Waiting Room to enable the setting.
3. Disable other options, including the ability for others to Join Before Host (it should be disabled by default, but check to be sure — see below). Then disable screen-sharing for nonhosts, and also the remote control function. Finally, disable all file transferring, annotations and the autosave feature for chats.
To disable most of these features, click on the gear-shaped Settings icon on the upper-right side of the page after you’ve logged in. From there, you’ll see the option to turn off most of the listed features.
Disabling screen-sharing is a bit different, but just as easy. Go to the host controls at the bottom of your screen, and you’ll see an arrow next to Share Screen. Click the arrow, then click Advanced Sharing Options. Go to Who can share? Click Only Host, then close the window.
4. Once the meeting begins and everyone is in, lock the meeting to outsiders (see our tips below) and assign at least two meeting co-hosts. The co-hosts will be able to help control the situation in case anyone bypasses your efforts and gets into the meeting.
To deputize your co-hosts, go to the same Settings icon, then to the Meetings tab. Scroll down to Co-host and make sure it is enabled. If Zoom asks you for verification, click Turn On.
Teams is an integral part of Office 365 and does offer more security as standard as the invitations are based on calendar invites from within Outlook. I would recommend using Teams and downloading the desktop app here: https://products.office.com/en-gb/microsoft-teams/download-app It is just then a matter of logging in with your email address and password. You can schedule a meeting from within Outlook and by clicking “Teams Meeting” will send the attendees joining instructions.
