Zoom Video Call – Security Tips

With lockdown measures implemented across the globe, due to the current COVID-19 pandemic, more people are looking for trusted digital communication tools. Digital communication tools are a great way to interact with family and friends, and are largely used by companies to collaborate with employees during these unprecedented times! One digital communication tool that has gained popularity is Zoom Video Call!

What’s not to love, it has attractive pricing, and it’s easy to use! However, as the number of users on this has spiralled to a high peak, there are BIG question marks over the security of this digital tool.

While the company has reacted to discoveries made by security researchers, to make this tool more secure, there will still be a possibility that the work done will not resolve every issue.


We have highlighted some security and privacy tips for Zoom Video Call users.


Registering with Zoom Video Call

There is an issue with public email domains on this platform. It causes Zoom to consider emails of the same domain as belonging to one company, and it will share their contact information with each member of that group. This would not be the case for common domains e,g gmail.com or hotmail.com.

Register your ZOOM account with your work email, if your Zoom is for work purposes, therefore it will only share your contact details with your work colleagues. If for personal use, we recommend setting up a separate email address, with a well-known public domain. This will help keep your details private.

Protecting Your Account

When setting up an account we always recommend using a strong password for protection, and even applying a two-factor verification, as this will make it harder to gain access to your account

NEVER share your Personal Meeting ID publicly online, if you do anyone with this can join any meeting you host, so be very careful. Never create public meetings as this will also disclose your personal meeting ID.

The trend of Zoombombing came from people sharing conference links on social platforms and resulted in Zoom meetings being targeted by online trolls who shared offensive content in the chat rooms.

Password Required for Meetings

Recently, by default Zoom turned on password protection, which is great for added security. Creating a password for your meetings is the best measure for ensuring that only people you want in your meeting room can attend. Be cautious not to disclose your Zoom account password instead of the meeting password, and don’t disclose your meeting password on event links online.

Screen Sharing Functions

Most video conference tools offer screen sharing options, so all participants can show their screens to others in the chatroom. Zoom also has this feature.

There are options to limit screen sharing abilities to just the host, or this can be extended to everyone on the call. The end-user does have the option if they want to turn their camera on/off, and if they want to turn their mic on/off in the meeting room.

Enable Waiting Room

This is also another measure you can use to control who joins your meetings. This makes the participants wait in a meeting room until you approve each one.

Use Web interface for Zoom Video Call

The Zoom app has already demonstrated a few issues, and the app still remains vulnerable, disclosing data with third parties etc. We recommend using Zooms web interface instead of downloading and installing the app. The web version sits in a sandbox in the browser and doesn’t have the permissions an installed app has, limiting the amount of harm it can potentially cause.

Don’t Fall For Fake Zoom Apps

Many malicious files have incorporated Zoom into their filenames, as the popularity of this digital tool has grown. If downloading the app, only do so from Zoom’s official website, or go to Apple Store / Play Store.
