Modelling of central processing unit work Denial of service attacks

Abstract

Denial of service attacks is one type of cyber attacks, when attacker tries to make some kind of service not available to its legitimate users. It becomes more relevant for service providers, however, for estimating of the potential threat it is simpler to use mathematical/programmable models instead of the real experiments. DoS attacks can vary in type, as well as its models. In this paper, we propose central processing unit work depletion DoS attack model and its characteristics. Also we use this model to examine attack success probability dependencies on the used queries arrival rate function as well as the optimal queries arrival rate function for the overall attack time period. The proposed model should enrich the other type of DoS models in the way of incorporating them. meanwhile, the implemented modelling experiments can be used as guidelines for central processing unit work depletion DoS attack efficiency optimization.
