5 ways to improve VoIP security

This article first appeared on Best in UC.

Companies everywhere are enjoying the big cost savings of voice over IP (VoIP). And as VoIP makes its move to mobile phones, the technology should become even more prevalent in years to come.

But just as with every other major technology to hit the marketplace, the longer it is around, the more VoIP becomes vulnerable to security breaches.

Over the last couple of years, the number of hackers attacking VoIP systems has grown steadily. What can these hackers do? They can:

  • Hijack your phones and use them to make costly overseas calls
  • Eavesdrop on phone conversations
  • Make recordings of phone conversations
  • Steal information discussed while they are eavesdropping and recording

Most disturbing of all is the fact that VoIP hacking is relatively easy. With just a quick search of the Internet, even a somewhat unskilled hacker will have all the tools he or she needs to tap into your VoIP system.

Don’t believe me? A quick Google search will reveal hundreds of victims, whose accounts were used to make phone calls that added up to the thousands – or even millions. Imagine the nightmare these individuals and companies faced with their VoIP providers, credit agencies and more.

Don’t let a hacker turn your money-saving VoIP into a security nightmare. Instead, take these basic steps to protect your phones – and your business. Then, you can enjoy the cost savings of this innovative technology, without the worries.

  1. Change the default password. Yes, this sounds simple and obvious. But many accounts are left with their default passwords intact. Make sure that your account has unique passwords in place.
  2. Use separate routers for Internet and phone service. VoIP should have its own data line. That way, you aren’t offering a backdoor to your data network via a VoIP router.
  3. Ensure that your VoIP router includes data-in-transit-encryption. This prevents hackers from listening in on your calls, and also prevents phone line hijacking.
  4. Ask your VoIP provider if they have a strategy to prevent denial of service (DoS) attacks, which can completely take down your phone line. If they don’t, find a new provider.
  5. Keep your team out of the phishing pond. Phishing doesn’t just happen by clicking an email link or answering a phone call. On VoIP, it occurs when the victim keys in their account information. The tones are recorded by the phisher-man scammer, who can then use that recording for identity theft.
