The denial-of-service dance

The attack on computer security include attack on confidentiality, integrity and availability. Confidentiality and integrity can be attacked by breaking cryptography but attack on availability can be made with mounting a denial of service attack by flooding a victim with input. Effective defense mechanism can be developed if the types of attack available to an adversary is known. A denial-of-service attack based on dance hall metaphor, created by David Gresty and his colleague at Liverpool John Moore's University, is a step toward such an understanding. They have created denial-of-service matrix and categorized attacks in two types, Local attacks such as power cut, unplugging or improper hardware connection and Remote attacks.
