Fig. 1From: On the reliability and availability of replicated and rejuvenating systems under stealth attacks and intrusionsState diagrams of intrusion for a system with n=3 nodes. In each sub-figure, each circle represents a global state of the system, with each inner triangle representing the state of a node: healthy (H) or intruded (I). Each arrow represents a transition where a single node changes from H to I. Each arrow corresponds to a constant intrusion rate (λ)Back to article page
