One of the biggest threats that can affect your company is Voice over Internet Protocol (VoIP) eavesdropping. This occurs when someone uses a software program to record or listen in on your VoIP calls without your permission. This can be done for malicious reasons, such as stealing trade secrets or committing fraud. To protect your business from such attacks, here are five handy tips:
Change default usernames and passwords
The first thing you need to do is to change the default password and username of your VoIP system. Many businesses don't bother to do this, but it's an essential security measure. By changing the default login credentials, you make it harder for hackers to gain access to your system. You can do this by logging into the admin panel of your VoIP system and changing the password.
Keep your VoIP system updated
Hackers are always looking for vulnerabilities in software. As such, it’s important to keep your VoIP system up to-date with the latest security patches. Check with your handset vendor regularly for updates and install them as soon as possible.
Keep your session border controllers (SBCs) updated
By doing so, you’ll be updating your VoIP’s antivirus software, which means your systems are better protected from all known types of malware. This also helps to ensure that your calls aren’t being rerouted through malicious VoIP servers, which could be used to eavesdrop on conversations.
Use a VPN or SRTP
Phone calls made over the internet are transmitted in the form of data packets. If these packets are intercepted, anyone can listen in on your conversations. To prevent this from happening, you need to encrypt your VoIP calls.
You can do this by using a virtual private network, which encrypts all the data passing through your device. Alternatively, you can use Secure Real-Time Transport Protocol, a VoIP security protocol that encrypts voice calls.
Train your employees
Your employees need to be aware of the dangers of VoIP eavesdropping. Teach them not to give out confidential information over the phone and make sure they know how to spot signs that someone may be trying to listen in on their conversations.
