A Review of Recently Emerging Denial of Service Threats and Defences in the Transport Layer

Denial of Service (DoS), and their larger-scale variant Distributed DoS (DDoS), attacks seek out and exploit various network vulnerabilities in order to overwhelm a node to the point of severe impairment. Our heavy dependency on services such as social media, file storage, streaming, and online banking often makes such services the target for attackers. As the Internet grows and changes with paradigms like Software Defined Networking (SDN) and cloud computing, new opportunities for DoS attackers also emerge. This survey aims to cover the latest strides in attack methodologies and related defence mechanisms specific to the Transport layer.
