A fully integrated protection scheme is necessary to efficiently implement an Infrastructure Resilience Plan to assure operational survival following a catastrophic event. Building on the first principles of security integration and fortifications practice, illustrated with case studies through history, the students explore site security surveys, different tools, mitigation methods, and models in common use and the assumptions and technology behind them in order to make informed decisions on how to approach and solve an infrastructure protection problem for the full range of event types. This is then practised in partnership with industry, analyzing real security integration issues for real clients, to whom the students will present their protection schemes.
