A third of organisations in the US and UK have suffered a distributed denial-of-service (DDoS) attack in the last 12 months.

A survey by Corero Network Security found that 38 per cent of US companies were likely to suffer a DDoS attack, compared with 18 per cent of their UK counterparts.

The survey of 300 medium- to large-sized enterprises found that 52 per cent of retailers (high street and online) were particularly worried about attacks, compared with 28 per cent of financial institutions and 11 per cent of manufacturing firms.

Andrew Miller, chief operating officer at Corero Network Security, told SC Magazine that some respondents were oblivious to attacks as they could see that performance was poor, but the reason could not be pinpointed.

“DDoS is a major, growing and evolving threat to global internet commerce. High-profile, ideologically motivated attacks by groups such as Anonymous have raised awareness of hacktivist-based DDoS attacks, but any enterprise may fall victim to unscrupulous competitors or cyber criminals,” he said.

“IT directors who believe that they are protected against DDoS attacks because they have traditional perimeter security technology, such as network firewalls, in place may be lulled into a false sense of security.”

The survey found that 62 per cent of respondents had technology in place to thwart an attack, while 53 per cent were still concerned about potential attacks.

Miller said: “More US companies have technology than in the UK, but it is an education thing as the firewall does do certain things but not enough to prevent this. It is about education and awareness as all things serve a purpose.”
