How to Make Sure Your VoIP Is Secure

So, you’ve got your VoIP set up and you’re ready to get started with cost-effective and future-proofed communications. But do you know whether your VoIP is truly secure, or how to ensure maximum network security?

In this article, we’ll outline factors that you might want to take into consideration when accounting for the security of your VoIP. By taking these small steps to ensure that your organisation is protected, you can go about your daily business unimpeded and without the worry of cyber-attack or VoIP fraud.

Steps to maximise your VoIP network security

1.    Strong passwords

It might seem obvious, but having strong passwords is the most effective way to ensure the network security of your VoIP. The cost of data breaches is exponential, and for a small business, could be catastrophic.

The first thing to do with a new VoIP solution is to change the password. Many will come with pre-set passwords, but these are frequently available online to even the least savvy hacker. Be sure to therefore change the password to something that’s secure. Going forward, it’s best practice to change passwords every six months to a year.

2.    Add the VoIP to your firewall

Just like any other data network or computing device, your VoIP needs to be secure behind your corporate firewall. Not every VoIP phone has firmware to protect against attack, so be sure to invest in either a firewall or an intrusion prevention system (IPS).

If you can swing for both, these work well in tandem, as they’ll track the traffic in the VoIP network, identifying and tracking any suspicious activity. It’s more complicated to do this with a VoIP phone in the homes of workers, but it’s nonetheless worth taking the time to do so in order to ensure maximal security.

3.    Stay on top of usage

A typical attack is known as an account takeover (ATO) – which is basically telecom fraud where the hacker places calls that will cost you, the business. By being aware of your usage, you’ll be able to tell when there’s an unusually high bill, or if calls have been placed in locations with no employee base. Being attentive to your organisation’s usage can help you to spot anomalies, which will in turn help you address potential fraud.
