Risk and Vulnerability Analysis (RVA) plays an important role in selfprotecting and self-healing of Autonomic Communication Networks (ACNs). RVA aims at identifying the weaknesses of the networks that may be exploited to compromise the normal functions, such as service deployment, file system access permissions, applications activations and so on. ACNs are recently proposed as business-objective driven high-level self-managed telecommunication networks with the adaptation capability to cope with increasing dynamics as well as widely distributed network demands. Adaptation capability termed as adaptability becomes the premise of realizing thorough autonomy. However, statistical observations reveal that adaptability vs. autonomy and adaptability vs. vulnerability have strong similarity with respect to quantitative results of trends, while autonomy vs. vulnerability are a pair of contradicting factors in practice. In this paper, we make a delicate information-theoretic analysis on the relationship between adaptability, autonomy, and vulnerability, and propose a solution to breaking down these coherent links by maximizing systemsâ adaptability and reducing systemsâ vulnerability simultaneously.
