DDoS Disasters

A distributed denial-of-service (DDoS) attack occurs when a bad actor seeks to make it impossible for a service to be delivered. DDoS attacks generally work by drowning a system with requests for data, overwhelming internet bandwidth, CPU or RAM capacity through an excessive volume or web server or database queries.

The impact of a DDoS attack can range anywhere from a minor service disruption or entire websites, applications or even businesses being taken offline. From a size perspective, DDoS attacks have grown from averaging just over 1 GBps in the 2000s to 100 GBps in 2010 to more than 800 GBps in 2016, according to Darren Anstee, CTO of Westford, Mass.-based Netscout Arbor.

Two of the largest recent DDoS attacks included the October 2016 strike against Dyn DNS – which peaked at 1.2 TBps – and February's attack on GitHub, which peaked at 1.35 TBps. As part of CRN's Cybersecurity Week 2018, here's a look at eight of the largest DDoS attacks today and what users can do to protect themselves from new and emerging threat vectors.
