Distributed Denial of Service (DDoS) attacks
By Michalis Kallitsis and Manish Karir
Distributed Denial of Service (DDoS) attacks that rely on the Network Time Protocol became prominent towards the end of December 2013. DDoS-based high attack volumes persisted for a few months within early 2014, until network operators started mitigating the problem and securing their networks. The NTP dataset provided by Merit Network captures the attacks at their peak level (reaching rates that exceed 300MBps or, equivalently, 2.4Gbps), as recorded by Merit's Netflow telescope. The dataset spans a period of 15 days, starting February 14, 2014.
