Global demand for network engineers with distributed denial-of-service (DDoS) mitigation skills has grown, but there aren't enough qualified people to fill the available roles.
That's one of the findings from recent research carried out by security firm Imperva, which said that demand for DDoS network engineering skills has grown 47 per cent in China and 30 per cent in the US in the past year.
Companies in the US, UK and Canada are taking longer to fill these available positions, and are seeing an increase in average listing days for them.
"In the US, this has increased from 27 to 37 days over a four-month period, the growth rate being over 75 per cent," said the firm's marketing VP Tim Matthews.
One of the reasons for the shortage is that effective knowledge of DDoS mitigation techniques requires a long list of qualifications that need to be gained over many years of experience.
Required skills cover network infrastructure, network platforms and DDoS mitigation technologies, specifically Border Gateway Protocol and Generic Router Encapsulation tunnelling.
"In addition, the engineer needs analytical, customer service and communication skills, and frequently needs to be a sleuth when deconstructing an attack," said Matthews.
Some experts are concerned that the rise of the Internet of Things will create an increased risk of DDoS attacks.
John McAdam, CEO of security firm F5 Networks, explained that a recent DDoS attack involved pinging cameras and any other internet-connected devices in people's homes.
"The camera will automatically say ‘no' so they couldn't get through, but they used the combination of ‘nos' to build up traffic and conduct a DDoS attack. If you can correlate all that data on a global basis, suddenly you're bringing down sites," he said.
