Answer to Question 2
A security threat is a challenge to the integrity of information systems that arises from one of three sources: human errors and mistakes, computer crime, and natural events and disasters. Human errors and mistakes include accidental problems caused by both employees and nonemployees. Computer crime includes employees and former employees who intentionally destroy data or other system components. It also includes hackers who break into a system and virus and worm writers who infect computer systems. Natural events and disasters include fires, floods, hurricanes, earthquakes, tsunamis, avalanches, and other acts of nature. Problems in this category include not only the initial loss of capability and service, but also losses stemming from actions to recover from the initial problem.
