How to deal with the four main VoIP security hazards

Any organisation that uses computer systems needs to be aware of the risks of data being compromised. But as voice communication moves to IP-based platforms too, the same risks apply to its traffic, so it’s important to take precautions to ensure your VoIP systems stay secure.

There are four key risks to VoIP and we’ll take a look at them in more detail and how service providers can deal with them.

Limiting call routes

One of the main attractions of VoIP for many is that it represents a major saving on call costs, particularly for international traffic – But of course, hackers and malicious insiders will seek to exploit this by abusing your account to make long-distance calls. The way around this is to restrict the numbers that can be called or to place a cap on the number of calls that can be made over a given period.

Call monitoring

Service providers will always seek to understand their customers’ needs and how this will affect their call volumes. Any sudden increase in the number or type of calls could be an indicator of malicious activity, so monitoring calls can provide early warning of a problem. The data can be used to identify the account originating the calls, so it’s possible to tell if an account has been compromised. Automation can be used to block suspicious activity – and thus minimise losses – pending an investigation.

Securing signups

One of the problems VoIP wholesale providers face is signups using false names and email addresses. This can be addressed by adding verification like ‘Captcha’ to sign up forms or allowing registration only via legitimate company emails. Visit IDT Express to find out how one provider is securing its systems. Auditing who has access on a regular basis and deleting old, unused accounts can also help security.

DDoS attacks

For any kind of online service, one of the biggest threats today is a DDoS (Distributed Denial of Service) attack. These can be devastating as they lead to legitimate users being unable to access your website or service. Traditional firewalls are relatively ineffective against this type of threat, so a more specialist approach is required. Hardware can be incorporated into the data centre in order to identify DDoS traffic and block it before it can affect the network.
