Top 5 VoIP security tips for businesses

VoIP, short for Voice over Internet Protocol, allows businesses to make free, or very low-cost, telephone calls over the Internet. This works anywhere in the world, regardless of the equipment that the other person is using.

While VoIP is a valuable tool for businesses, it is not without its problems. If the right security measures are not put in place, you could be subject to identity fraud and several other cybersecurity threats. Here’s what you need to know about securing your business.

Enabling Data Encryption

Data encryption refers to the act of changing electronic information into an unreadable state via the use of complicated algorithms and ciphers. Encryption should be an essential part of your overall cyber security strategy. Since VoIP data can travel over numerous networks, making it more susceptible to the possibility of being intercepted, it is particularly important here. The most popular tool for encrypting VoIP calls is Zfone, a free program that works on Windows, Mac, and Linux machines.

Implementing Authentication Techniques

Service abuse and toll fraud are among the most common cases of VoIP attacks. This allows individuals to make premium rate service calls to their own services, often located outside the country, and then charge the cost back on to your business. Implementing mutual authentication protocols between parties is one of the best ways to prevent this. This could be done through a password, pin, or other classified information.

Improving Password Credibility

However, these changes will be for nothing if your password strength isn’t up to the task. Malicious third-parties can break weak passwords easily by brute forcing through the possible combinations. You should always change your default password or pin that was established by your network provider, and then look to modify your passwords on a regular basis. While it can be frustrating to have to change a password having just gotten use to it, it’s in company’s best interests.

24/7 Monitoring

According to a recent report from Nettitude, 88% of VoIP attacks occur outside normal working hours. This means that it can be difficult for your in-house I.T. staff to try and rectify the problem in good time. Third-party security firms can ping your servers every hour on the hour to check that they are functioning as they should. If they find any problems, they can immediately try the fix the situation and then pass on the information they’ve gathered to your employees

Establishing Strong Firewalls

Finally, firewalls are used to create barriers between your system and cybersecurity threats, like malware. The servers that control your central communication system can have firewalls installed to guard all of the devices connected, including VoIP. Service providers like Gradwell can help you to configure your setup to your needs and ensure that your firewall isn’t blocking any VoIP traffic it shouldn’t. As with any software, you should make sure that you update to the latest version so that you have the most up-to-date protection.
