Summary:Modern networks are dynamic with configuration changes that introduces a set of challenge to the network administrator in terms of security and availability. Here, the major challenge faced by the administrator is the increasing number of vulnerabilities with the uncertainties related to defense deployment options and how these options affect the network availability over time. This work proposes a hierarchical model-based approach to evaluate the availability of dynamic networks considering the deployment of different hardening options. In particular, this work adopts reliability block diagrams and Petri nets to represent and analyze dynamic network environments and evaluate their availability. A case study is presented to demonstrate the feasibility, usefulness, and scalability of the proposed approach for computing the availability of dynamic networks considering different hardening options. The proposed approach can be helpful for network administrators who are in charge of choosing the best hardening options taking into account the impacts on availability.
