VoIP security checklist: Best practices for protecting your VoIP network

Voice over Internet Protocol (VoIP) is quickly becoming the standard for businesses looking to cut costs and improve communication. However, with an increased reliance on digital networks comes a heightened risk of security breaches and data loss. To protect your business's VoIP network from such threats, it's essential to take proactive steps to secure your system, such as encrypting communications, using firewalls, and regularly updating software.

To help you get started, here is a checklist of best practices for protecting your VoIP network.

  • Enforce a strong password policy. User authentication is key to keeping VoIP networks secure. All users should be required to use strong, unique passwords for their accounts. If applicable, secure any connected devices with a PIN code or other form of authentication.
  • Keep firmware, software, and operating systems up to date. Installing updates and patches is essential to protect against vulnerabilities that could be exploited by hackers and other malicious actors. Make sure to check for updates regularly and install them as soon as they become available.
  • Require Wi-Fi encryption. If your VoIP network is connected to a Wi-Fi network, make sure it is encrypted with WPA2 or another secure protocol. This will prevent hackers from accessing your VoIP network through the Wi-Fi connection.
  • Use a virtual private network (VPN). A VPN connection adds an additional layer of security to your VoIP network by encrypting communications between the devices, making it more difficult for malicious actors to eavesdrop on conversations. Consider an enterprise-grade VPN solution to ensure maximum protection.
  • Implement remote device management. Remote device management allows you to manage your VoIP devices from any location, as well as monitor usage and detect potential threats. This is especially helpful in distributed workforces or teams that must remain connected while on the go.
  • Regularly review your call logs. Most, if not all, VoIP systems generate detailed records of calls, which can help detect suspicious activity or spot potential problems with the system. Make sure to review these logs on a regular basis to check for any irregularities, such as unusual call times or locations and high call volumes.
  • Disable unnecessary calling features. Some VoIP systems come with features such as conference calling, international calling, and other extras that may not be necessary for your business. Disable any features you don't need to reduce the risk of potential security threats.
  • Deactivate inactive accounts. If an employee leaves your organization, make sure to deactivate their VoIP account. This will prevent them from accessing the system and potentially compromising its security.
  • Encourage employees to report strange activities. This could be anything from missing voicemails to suspicious international calls. Stress the importance of reporting any irregularities to the IT team or administration staff immediately, so they can investigate and take appropriate action.
  • Educate employees on basic security practices. Teach your staff how to recognize potential threats and what precautions they should take when using the VoIP system. Conduct ongoing training sessions on topics such as strong passwords, phishing scams, and other security concerns. When employees are aware of the risks, they can easily spot malicious activities and take steps to protect themselves.

By following these best practices and staying up to date on the latest security threats, you can ensure that your VoIP network is secure and safe from potential attacks and that your business will remain connected and productive.
