Distributed denial of service (DDoS) attacks have caused severe service interruptions and financial damages to organizations throughout 2015. Radware’s 2015-2016 Global Application and Network Security Report revealed that over 50% of organizations have experienced some type of DDoS attack in 2015. Yet, as much
as 50% of the organizations cited that they are unprepared for such attacks. DDoS attacks are increasing in quantity and severity as these attacks become increasingly complex and persistent. Typical DDoS attacks have evolved to include simultaneous multiple attack vectors that test simple mitigation techniques. Attacks using dynamic IP attacks that challenge mitigation through simple blacklisting are now ubiquitous. Volumetric network-level DDoS attacks at staggering throughput rates of hundreds of Gbps and hundreds of millions of packets per seconds have become commonplace, disabling organizations’ network and infrastructure. SSLbased and application-level DDoS attacks that are effective in exploiting bottlenecks in the IT architecture of enterprises have become more prevalent.
