The U.S. government is highly concerned that critical infrastructures in the United States are vulnerable to a cyber attack from criminal gangs, terrorists, or hostile governments. Assume you are working for a medium-sized accounting firm in Shamrock, Texas. One of the partners in the firm has asked you, as a recent graduate, to write a report that (1) makes a list of the five critical infrastructures that could be damaged by such an Internet attack, and then (2) using your list of five infrastructures, pick one and determine how damages to it would affect the firm's operations, and (3) make suggestions as to how to mitigate these problems. In answering part (2) develop a timeline for the shutdowned infrastructure showing how the firm's operations would be affected the longer the shutdown extended into the future.
