5 Best Practices to Keep Your Virtual PBX System Secure

The telecommunication requirements for startups and large enterprises vary due to size, features, equipment, etc. But there’s one thing both types of business share in common: the need for a reliable and secure communication system. With the popularity of virtual PBX (Private Branch Exchange) systems, businesses now more than ever need to take measures to ensure their system is safe to avoid being vulnerable to various security threats inherent to web-based technologies.

Virtual PBX security threats are diverse and varied, but one of the most common include PBX hacking. This is where criminals penetrate your PBX system to make unauthorized calls. This can result in substantial call charges being incurred on your account.

So how can you protect yourself from PBX hacking and other more damaging security threats? Take note of the following security measures to keep you and your business safe:

  1. Use strong passwords

One of the easiest yet often overlooked security measures is setting strong passwords. Using weak passwords (such as birthdays, names, and default passwords) is like opening the door for hackers since it requires almost no effort to hack into the system.

To make sure you’re not making it easy for cyber-criminals, use strong passwords in your PBX phones and accounts for both users and administrators. This means using a password that contains a minimum of 16 characters that include a combination of uppercase and lowercase letters, numbers and symbols. Also remember to change default admin passwords regularly, especially if you’re using modern IP PBX servers that can be configured through a web portal.

  1. Use a VPN for remote workers

If your PBX system supports a large number of mobile devices (especially if you have remote employees or staff who are constantly on-the-go), then encrypting traffic through a Virtual Private Network (VPN) is a wise move. With a VPN, users can access a private network securely and send and receive data remotely across shared or public networks.

  1. Monitor usage

In order to avoid fraud and to detect network-based attacks on your IP PBX system, it’s important that you monitor usage and actively track call logs and history.  Attacks on a PBX system are usually known to create an unusually large amount of network traffic, so blocking international call access to countries you don’t usually dial is a good idea.

  1. Keep your software up to date

Another way to safeguard your PBX system and your business is by keeping your PBX software updated. Typically, the most recent version of a software is often the most secure (bugs and other potential exploits are found and fixed).

When updating your PBX, remember to do a complete backup of your system (although performing regular backups of your entire system is also recommended). Also notify end users of the update, in case it will lead to some downtime.

  1. Talk to your service provider

Finally, talk to your PBX service provider. Be sure to ask about security issues such as how data is stored and transmitted, and the measures they have established in case of a network attack. This is something you would want to do even before you choose a provider.

Final Thoughts

Virtual PBX systems offer a host of benefits to startups and growing businesses, but when not managed properly, cyber-criminals can use your phone system as an opportunity to commit fraud and gain access to your confidential company data. That is why security should always remain a priority for organizations.
