Divide the class into three teams. Each team will access various search engines for information on Terry Childs, who was the network administrator for the City of San Francisco, California. One team will act as the prosecution and will present the case against Childs. The second team will act as the defense and defend Childs. The third team will sit as the jury and will vote on whether Childs is guilty or innocent. (The jury should not feel constrained with the fact that Childs has already been found guilty.) (a) A single point of failure is a component of a system that, if it fails, will prevent the entire system from functioning. For this reason, a single point of failure is clearly undesirable, whether it is a person, a network, or an application. Is Childs an example of a single point of failure? Why or why not? As he was indeed found guilty, what should the City of San Francisco (or any organization) do to protect itself from this type of problem?
