IT managers indicate increased concerns over DDoS

by Brian Sims

Research commissioned by Corero Network Security has indicated that businesses are increasingly concerned about the impact of a targeted Distributed Denial of Service (DDoS) attack. Of respondents, 41 percent of IT managers were ‘highly’ or ‘extremely’ concerned about being the victim of an attack. This figure had grown from 29 per cent in 2012. The survey compared attitudes over the last two years among 100 mid- to large-sized UK enterprises. Results also indicated that the number of UK organisations experiencing attacks year-on-year had climbed to 25 per cent in 2013 from 18 per cent during the previous period. IT managers in the financial sector were particularly concerned, with 56 per cent claiming a ‘high’ or ‘extreme’ level of concern; the similar figure for last year was 28 per cent. With regard to protection, 31 per cent said they had specialised anti-DDoS technology in place, while 36 per cent stated that they were relying solely on their firewalls to protect them against DDoS attacks, and did not intend to augment their protection. A further 24 per cent of respondents said they had a firewall in place but intended to purchase specific anti-DDoS technology. Another major change over last year’s survey was the perceived motivation for attacks. In 2012 political motives were most commonly cited by 33 per cent of respondents, while in 2013 36 per cent of respondents thought attacks were carried out purely as a form of malicious entertainment. The retail and financial sector viewed financial extortion as the main motivation behind the attacks, while the manufacturing sector unanimously blamed political reasons. The survey highlighted increased sophistication of attacks, as 33 per cent were application layer DDoS attacks, 37 per cent volumetric attacks and 30 per cent were other targeted or zero day attacks.
