A comprehensive study of distributed denial of service attack with the detection techniques
… by the constant threat from numerous kinds of attacks. One such attack is called a distributed denial of service attack and leads to a problem starting with a temporary delay of the server in order to terminate the service's non-availability. A honeypot may be a kind of lure, but in order to …

Defense against network attacks using game theory
… has become ubiquitous, the risk posed by network attacks has greatly increased. Network attacks have been used to achieve a wide gamut of objectives ranging from overloading a website to accessing classified data. Effective defense against such attacks is a critical research area. In this thesis, …

Proof-of-Work Based Mitigation of Real Time Video DDoS Attacks
… and complexity, Distributed Denial of Service (DDoS) attacks grow in size and complexity alongside it. One particularly common form of DDoS attack is the TCP SYN flood, which exploits the TCP handshake process to exhaust server resources. This thesis investigates the use of a novel proof-of-work …

Mitigation of Different Network Attacks and Optimization in Software Defined Network
Cyber attacks are growing with the increase in internet usage. There are several types of network attacks including volumetric and non-volumetric attacks.In a volumetric attack, the target resource is taken down with a huge amount of traffic. Distributed denial-of-service (DDoS) and transit-link …

Assuring network service with bandwidth and integrity based fairness
During an Internet distributed denial-of-service (DDoS) attack, attackers pose as a superpower overloading bandwidth and services that otherwise would have been lightly used by genuine users. These legitimate users send few packets and occasionally back-off and fail while competing for resources. …
