How to Secure Your VoIP Connection

More businesses are turning to VoIP telephony due to fair prices by providers as well as a need to have a means of communication that is integrative, intuitive and cost-effective. That being said, VoIP uses the internet to transmit voice data, making it a security target for malicious hackers and bot viruses.

It’s imperative that you secure your VoIP connection if you head a large corporation with sensitive information stored on your computers and servers. In this post, we’ll expose some of the most common VoIP security vulnerabilities and what you can do about to fix them.

Here is a list of some of the most common VoIP security challenges:

  1. Due to the fact that VoIP relies on an internet connection, you may get individuals trying to call you just to get into your network to discover any sensitive information that they can sell in the black market. If your network is not secured, you will get unsolicited calls that may probe you to release information about your company unknowingly. While on the phone, these malicious individuals may also be busy at work planting a program or virus in your network.
  2. Spam is also common in the VoIP world, and it involves receiving marketing phone calls from companies trying to sell you a product or service. VoIP spam is called SPIT, or Spam over Internet Telephony.
  3. VoIP relies on electricity as well as a stable internet connection. Should these two go out, you may lose valuable man hours as well as leave your network open for hackers to attack, especially if it was unsecured in the first place.

Here are some things you can do to secure your VoIP connection:

  1. Make sure that your VoIP equipment is from a reputable company or supplier and that it comes with vital features such as Wi-Fi Protected Access, and IEEE 802. 11i.
  2. It’s always a good idea to have two connections; one for your VoIP network and the rest for all other office-based communications. This way, you’ll always have a backup connection should one go down when you’re in the midst of transmitting sensitive information.
  3. Always update your antivirus software regularly.
  4. Look into securing your Firewall, especially if you still receive spam calls when it’s up.
  5. If your VoIP devices come with authentication and encryption features, make sure that they are always on.
  6. Consider getting a VPN for your VoIP since this will allow you to transmit data packets through a secure and undetectable tunnel.
  7. Carry out an audit for all user accounts on a regular basis to see if there are any vulnerabilities you can cover up.
