In this paper we quantitatively evaluate the security of intrusion tolerant systems with preventive maintenance subject to DoS (Denial of Service) attacks. More specifically, we develop two semi-Markov cost models and describe the stochastic behavior of two intrusion tolerant systems with different preventive maintenance policies. The optimal preventive maintenance schedules are analytically derived to minimize the long-run average costs. We further perform the sensitivity analysis of the model parameters through numerical experiments. The results obtained here would be also useful to design ubiquitous systems subject to external malicious attacks.
