Quantitative analysis has always been a difficult problem in security analysis of intrusion tolerance systems. An intrusion tolerance model based on multiple recovery mechanisms is introduced in this paper and how to quantify the security attributes of the model is proposed. A state transition model with recovery states more accurately describes the dynamic behavior of the system. Considering that...
Recovery is a promising approach for building intrusion tolerant systems that remove or minimize the effects of malicious attacks. In this paper, a Virtualization-based Recovery approach for Intrusion Tolerance systems (VRIT) is proposed. We present the architecture of the VRIT, construct the state transition model of the VRIT, and analyze quantitatively the security of the VRIT system. We characterize...
