As communities become more reliant on information technology, they are also becoming susceptible to attacks. In particular, critical cyber infrastructures are at risk. However, because of the interdependence of the critical infrastructures, there is a pressing need to develop a group centric (involving different infrastructures) framework, which can help improve threat management and incident response. 1. Discuss if it is possible to develop such a framework. 2. What formal methods can be modified or developed further to ensure critical infrastructure protection. 3. Consider a scenario, such as health care, and suggest how such a framework could be used.
