10 Video Conferencing Security Best Practices

Video conferencing has become the new normal for many businesses. Here are 10 security best practices to keep in mind to keep your meetings secure.

In the past few years, video conferencing has become an increasingly popular way to communicate both within businesses and between businesses and their customers. The convenience and flexibility of video conferencing has made it a go-to choice for many organizations.

However, as with any technology, there are security risks associated with video conferencing. In this article, we will discuss 10 best practices for securing your video conferencing system. By following these best practices, you can help ensure that your video conferencing system is secure and your conversations are private.

1. Use a Virtual Private Network (VPN)

A VPN encrypts all of the data that is sent between your device and the video conferencing server. This means that if someone were to intercept the data, they would not be able to read it.

Additionally, a VPN can help to prevent man-in-the-middle attacks. In a man-in-the-middle attack, an attacker intercepts the data being sent between two devices and then impersonates one of the devices. This can allow the attacker to gain access to sensitive information or even take control of the video conference.

Using a VPN will help to protect you from these types of attacks and keep your video conferences secure.

2. Encrypt Your Data

When you make a video call, your data is sent over the internet in real-time. This means that if someone were to intercept your data, they could potentially see and hear everything that’s happening on your call.

To prevent this from happening, you should always encrypt your data before sending it over the internet. This way, even if someone does intercept your data, they won’t be able to read or listen to it because it will be encrypted.

There are many different ways to encrypt your data, but one of the most common and effective methods is to use a Virtual Private Network (VPN). A VPN encrypts all of the data that’s sent between your device and the VPN server, making it impossible for anyone to eavesdrop on your calls.

If you’re not using a VPN, you should still encrypt your data with a secure messaging app like Signal or WhatsApp. These apps use end-to-end encryption, which means that your data is encrypted before it leaves your device and can only be decrypted by the person you’re communicating with.

3. Disable File Sharing

When file sharing is enabled, anyone in the meeting can share their screen with the other participants. This means that if someone were to accidentally share their screen, sensitive information could be exposed.

Additionally, if someone were to deliberately share their screen with malicious intent, they could easily distribute malware or viruses to the other participants. By disabling file sharing, you can help prevent these types of security breaches.

To disable file sharing in Zoom, go to Settings and select the Security tab. Then, under File Transfer, select the option to “Disable File Transfer.”

4. Keep your Software Updated

When you use an outdated version of video conferencing software, you open yourself up to security vulnerabilities that have already been fixed in newer versions. By using an older version, you’re essentially using software with known security holes.

It’s important to note that not all software updates are created equal. Some updates are more significant than others, so it’s important to pay attention to the type of update being released. For example, a major update might introduce new features or fix critical security vulnerabilities, while a minor update might only address non-critical bugs.

If possible, you should always try to install the latest major update for your video conferencing software. This will help ensure that you’re using the most secure version of the software available.

5. Don’t Share Sensitive Information Over Video Conferencing

When you share sensitive information over video conferencing, you’re giving potential attackers a wealth of information that they can use to their advantage. By sharing this information, you’re increasing the chances that it will be leaked or stolen.

Instead of sharing sensitive information over video conferencing, send it through a secure channel such as encrypted email or a secure file transfer protocol (SFTP) server. This way, you can be sure that your information is safe and secure.

6. Avoid Public Wi-Fi Networks

Public Wi-Fi networks are unsecure. They’re often not password protected, which means anyone can join the network and listen in on conversations. What’s more, these networks are often not encrypted, meaning that data sent over the network can be intercepted by third parties.

To avoid these risks, only use video conferencing on private, secure networks. If you must use public Wi-Fi, make sure the network is encrypted and use a VPN to encrypt your data.

7. Securely Dispose of Old Devices

When you’re done with a device, it’s important to make sure that all the data on it is wiped clean. If you don’t do this, someone could potentially access sensitive information, like customer data or company secrets.

There are a few different ways to securely wipe data from a device. One is to use a software program that will overwrite all the data on the device with random characters. This makes it impossible to recover the original data.

Another way to wipe data is to physically destroy the storage media. This can be done by crushing the hard drive, for example.

Once the data is wiped, you can then dispose of the device in whatever way you see fit.

8. Limit Access to Meetings

If you’re using a video conferencing platform like Zoom, Google Hangouts, or Skype, it’s important to make sure that only people who are supposed to be in the meeting have access to it. That means setting up a password for the meeting, and not sharing that password with anyone who isn’t supposed to be in the meeting.

It might seem like an extra step, but it’s an important one to take to ensure the security of your video conference. By taking this simple step, you can help to ensure that only the people who are supposed to be in the meeting are able to join, and that no one else is able to eavesdrop on your conversation.

9. Use Multi-Factor Authentication

With multi-factor authentication, a user is required to provide two or more pieces of evidence (or “factors”) to verify their identity before being granted access. This could include something they know, like a password; something they have, like a physical token or their smartphone; or something they are, like their fingerprint.

The benefit of using multi-factor authentication is that it makes it much harder for an attacker to gain access to your video conferencing system, even if they have stolen a user’s credentials. Even if an attacker knows a user’s password, they would also need to have the user’s physical token or smartphone in order to gain access.

There are a few different ways to add multi-factor authentication to your video conferencing system. One option is to use a third-party service, such as Google Authenticator or Authy. These services generate one-time codes that can be used to login, and they can be easily installed on a user’s smartphone.

Another option is to use hardware tokens, which are physical devices that generate one-time codes. These can be expensive, however, and may not be practical for all users.

Finally, you can also use biometrics, such as fingerprints or iris scans, as a form of multi-factor authentication. This requires special hardware, such as fingerprint scanners or iris cameras, but can be a very secure option.

10. Use a Firewall

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall can be hardware-based, software-based, or a combination of both.

Using a firewall helps to protect your video conferencing system from external threats such as hackers and malware. It also helps to control access to your system and prevent unauthorized users from joining your conference calls.

When configuring your firewall, be sure to allow traffic on the following ports:

– TCP/UDP port 1720 for H.323 call setup
– TCP port 80 and 443 for HTTP and HTTPS
– UDP port 3478 for STUN/TURN
– UDP port 5004 for RTSP
