20. The virtual city in cyber-space called San Lewis Rey has devoted $100 million to protect its critical infrastructure sectors, which consist mostly of a robust subway system, major telecommunications network, electrical power grid, and water utility. After an initial study performed by an engin- cering firm, the city council realized that these four infrastructures would be very costly to protect. Estimates to provide hardening of the physical components of each were: a $1.5 billion: Subway System. b. $500 million: Telecommunications Network $250 million: Electrical Power Grid. d. $3.3 billion: Water utility components. The total for all four sectors amounts to more than $5.5 billion or 55 times more than the city's $100 million budget! What should be the San Lewis Rey strategy for protecting its four major infrastructures? 21. For each of the five strategie principles described in this chapter, show how each principle may be applied to San Lewis Rey to provide the best EXERCIES 27 counter-terror protection possible, given limited funds. That is, apply each of the following strategies to this challenge: 1. It takes a network to fight a network b. Secure the hubs, not the spokes c. Spend 80% on 20% of the country d. Think dual purpose Think asymmetric 20.
