According to the results of a recent survey of 220 service provider, enterprise, cloud, hosting and other network operators worldwide, more than 70 percent of respondents operating data centers experienced DDoS attacks between November 2012 and October 2013, a significant increase from under 50 percent the previous year.
Arbor Networks' 9th Annual Worldwide Infrastructure Security Report (WISR) also states that DDoS attacks reported by respondents peaked at 309 Gbps, with many reporting attacks larger than 100 Gbps. In all previous years of the survey, the largest reported attack was 110 Gbps.
More than a third of respondents operating data centers also said they experienced attacks that exceeded total available Internet connectivity, nearly twice the number from the previous year -- and about 10 percent of those respondents saw more than 100 DDoS attacks per month.
Almost a quarter of respondents that offer mobile infrastructure said they've seen DDoS attacks impacting their mobile Internet infrastructure, more than double the proportion reported the previous year -- and more than 20 percent of those offering mobile services said they've suffered a customer-visible outage due to a security incident.
“From the ISP to the enterprise, IT and security teams are facing a dynamic threat landscape and very skilled and patient adversaries," Arbor Networks president Matthew Moynahan said in a statement. "Our ninth annual report showcases that very clearly. There is no single, magic bullet solution and it is a mistake to think technology alone can secure a network."
