A Literature Review of the Seriousness of Flooding-based DoS Attack

The denial of service (DoS) attack has evolved into one of the most serious security threats on the Internet, aimed at preventing a service from being available. To launch a distributed denial of service (DDoS) attack, a group of compromised machines is used. This paper discusses and analyzes certain flooding-based DoS attacks, which flood a network or a specific system inside a network with unwelcome traffic, in addition to a discussion of the classification of DDoS defense mechanisms, and countermeasures and presenting a comparison of selected Flood-DoS attacks mitigation algorithms . Finally, we explore the severity of distinct DoS attacks by comparing each attack type to a set of criteria and highlighting some of the future research directions.
