Keeping Your VoIP System Secure

Security incidents are a growing problem in the U.S. and across the globe. The safety of your private files, as well as the personal data your company holds, are only as safe as the weakest link your security measures. Let’s look at a few of the most common threats to a VoIP system, and discuss how you can keep your business secure.

Threat Assessment: Traditional Phone Systems vs. VoIP

A traditional phone system is subject to security threats. These include surveillance that can intercept and record calls and messages. VoIP systems are not immune to such threats. However, since VoIP takes place over the Internet, different security measures are needed to protect your communications. Three essential security measures for protecting VoIP communications include:

  1. Data Encryption – Even if a message is intercepted, make sure it is indecipherable.
  2. Firewalls – Keep out unwanted eyes and ears.
  3. User Authentication – Strong authentication methods reduce the risk of infiltration.

What Are the Most Important Security Concerns?

Identity and Data Theft – This is one of the easiest problems to solve. Most people who will listen in on your calls will use free spyware that’s available online. This software targets companies with no security. Implementing the three measures noted above will make the software useless against your company.

Abusing Service – This refers to hackers hijacking your VoIP service for their own personal use. This is often done at a time when companies won’t notice resources being drained, such as late at night or on the weekend. Unfortunately, you still get stuck with the bill for services the hackers used. Secure passwords and firewalls keep hackers from making you foot the bill for their unlawful use of the service.

Service Interruptions – Downtime costs money for your business. Whether the downtime is caused intentionally, or it is indirectly caused by other criminal activity, this doesn’t affect the difference in cost to your business. This means using firewalls to fend off denial-of-service attacks. You need to protect your physical property because a criminal bringing down your electrical system or Internet service will affect your VoIP service. Keep your building secure, perhaps with keycard entry and extra protection for parts of the building that control important systems.
