Because Voice-over-Internet-Protocol phone (VoIP) phone systems have many benefits compared to the traditional Key System Unit (KSU) phone systems, many businesses are adopting VoIP systems into their infrastructure. While there are many benefits to the adoption of VoIP phone systems into your company, the adoption of any system or technique must be carefully evaluated to ensure that it provides reasonable security for your internal and external communications. In this post, we will discuss the two most common security concerns regarding VoIP phone systems so you are able to make an informed decision regarding VoIP phone systems.

SPIT Strategies

Just as email spam floods your inbox with unwanted messages and socially engineered emails, scam artists can target your system with either robocalls or socially engineering efforts (known as SPIT – SPam over Internet Telephony). Both robocalls and social engineering schemes consume the time of your employees who are likely believing the calls to be from customers or partners. SPIT efforts are often tied to caller ID spoofing strategies that allow hackers to enter your network and glean information about your phones, routers, and computers. This enables them to harvest your network for phone numbers, among other things, which are then sold to scam artists.

DDoS Attacks

Distributed-Denial-of-Service (DDoS) attacks are becoming increasingly common against VoIP systems as hackers realize they can prove their hacking skills by temporarily crippling a company’s network. Basically, DDoS attacks usually consist of hackers posing as online customers and sending enough requests to your company’s servers to clog or fill its bandwidth level, thus preventing legitimate users from accessing your network, whether it is a website or VoIP system.

Strategies to Protect Your VoIP System

There are many steps that can be taken to reduce your vulnerability to SPIT and DDoS attacks. Using strong, complex passwords for all phones, routers, switches, etc. is a great deterrent to hackers. Encryption is important as well, especially regarding VoIP systems, as well as enabling the appropriate hardware and software settings for increased security. Keeping your firmware and software updated and using Session Border Controllers are other ways to secure your network from malicious users.
