Securing Business Communications: A Guide to Phone Line Cybersecurity

We are in an era where data breaches and cyberattacks are becoming more and more common. The reason why is simple: we are becoming more reliant on technology, so by stealing people's data, you can gain access to a lot of personal information. Just look at M&S and the CO-OP, it’s only a few months ago when they were subject to a major hack, which stole a lot of people's data, costing them a lot of money in the process - this was a real eye opener for other big businesses.

While many companies focus their resources on securing emails, networks and cloud services, one area which is also important is your phone line security. Most companies have a business phone line, which a lot of senior people use. The last thing you want is for someone to gain access to your phone line and be able to listen in on important calls. Whether your business relies on traditional landlines or VoIP (Voice over Internet Protocol) systems, securing these channels is essential to protect sensitive information and maintain customer trust.

To help support your business, we have put together a guide on keeping your phone lines secure.

Use encrypted VoIP solutions

A lot of companies go down the route of VoIP for their phone line solution. If this is the case for your business, make sure your provider offers end-to-end encryption for voice data. By using this security measure, it is significantly harder for attackers to eavesdrop or tamper with calls. This comes as standard with a lot of providers, so chances are you will have this security measure in place, but it’s good for you to confirm.

Keep software and firmware updated

Technology companies are releasing updates for their software all the time. The reason updates are released is to offer you new and better features, as well as patch any security vulnerabilities that have been discovered. On a regular basis, make sure you check for updates on your VoIP software, hardware (routers, handsets), and firewalls and apply them whenever you see a new update released. The longer you go without updating your software, the more likely it is that someone could exploit the vulnerability and interfere with your phone lines.

Train your employees

When it comes to cyber attacks, one of the best ways to protect yourself is to train your employees. In the case of phone line cybersecurity, the more training you offer, the more protected you will be. Educate your employees on how to spot phishing attempts, verify caller identities, and report suspicious behaviour. Give your employees regular refresher courses on cybersecurity; this way, anything that is forgotten over time is remembered.
