DDoS Attack Size Soars, Volumes Are Up, Arbor Networks Finds

The threat of distributed-denial-of-service (DDoS) attacks remains a growing concern as the attack volume moves ever higher, according to Arbor Networks' latest Worldwide Infrastructure Security Report. The WISR is based on survey data collected from 448 service providers around the world and provides some noteworthy insights into the current state of DDoS attacks. The peak DDoS attack size increased to 500G bps this year, up 20 percent from last year's level, according to the annual study. Overall attack volumes are now increasingly saturating the Internet connectivity of targeted organizations, with 51 percent reporting that DDoS completely saturated their bandwidth, up from 35 percent in last year's report. The study also found that attackers continue to employ DDoS reflection as a technique to amplify attack bandwidth. Also noteworthy is the duration of DDoS attacks, which the WSIR reports as being largely six hours or less, for most victims. In this slide show, eWEEK examines key takeaways from the study.
