Arbor Networks’ ATLAS Data Shows the Average DDoS Attack Size Increasing in Q2

Arbor Networks released Q2, 2015 global DDoS attack data that show strong growth in the average size of DDoS attacks, from both a bits-per-second and packets-per-second perspective.

The largest attack monitored in Q2 was a 196GB/sec UDP flood, a large, but no longer uncommon attack size. Of most concern to enterprise networks is the growth in the average attack size. In Q2, 21% of all attacks topped 1GB/sec, while the most growth was seen in the 2-10GB/sec range. However, there was also a significant spike in the number of attacks in the 50 – 100GB/sec range in June, mainly SYN Floods targeting destinations in the US and Canada.

Arbor Networks Chief Security Technologist Darren Anstee said, “Companies need to clearly define their business risk when it comes to DDoS. With average attacks capable of congesting the Internet connectivity of many businesses it is essential that the risks and costs of an attack are understood, and appropriate plans, services and solutions put in place. ”

Arbor’s data is gathered through (Active Threat Level Analysis System) ATLAS, a collaborative partnership with more than 330 service provider customers who share anonymous traffic data with Arbor in order to deliver a comprehensive, aggregated view of global traffic and threats.
