Arbor Networks Inc. , a provider of DDoS and advanced threat protection solutions for enterprise and service provider networks, has 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.
“Extremely large attacks grab the headlines, but it is the increasing size of the average DDoS attack that is causing headaches for enterprise around the world,” said Arbor Networks, Chief Security Technologist, Darren Anstee. “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. ”
Active Threat Level Analysis System (ATLAS)
Arbor’s data is gathered through 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.
ATLAS collects 120TB/sec of Internet traffic and is the source of data for the Digital Attack Map, a visualization of global DDoS attacks created in collaboration with Google Ideas.
