The persistence of DDoS attacks has increased significantly in just the past few years, according to research from Imperva.
Watch the below video with Imperva vice president Tim Matthews, recorded at InfoSecurity Europe 2015, to learn more about Imperva's work on DDoS attacks.
Based on its experience fighting DDoS attacks on behalf of its customers, it found that the longest sustained attack was 64 days and that companies that have been attacked once are likely to be attacked again.
“Once targeted by an application layer attack, a website will likely be attacked again once every 10 days on average, with 17 percent of sites attacked more than five times, 10 percent attacked more than 10 times, and several sites that were attacked every day, during the 72-day research period,” the company said.
The researchers also found a disturbing shift in DDoS bots, with more impersonator bots assuming non-generic identities to bypass signature-based security.
“The long durations and advanced, signature evading methods suggest DDoS is beginning to resemble advanced persistent threats,” the company said.
