Answer to Question 1

Quadrant II represents threats that are deemed high risk and very likely to occur. Threats include impostors, eavesdroppers, and thieves. An eavesdropper, in this context, is a person or device that can listen in on and copy Internet transmissions. People who write programs or manipulate technologies to obtain unauthorized access to computers and networks are called crackers or hackers.
A cracker is a technologically skilled person who uses their skills to obtain unauthorized entry into computers or network systems  usually with the intent of stealing information or damaging the information, the systems software, or even the systems hardware.

Answer to Question 2

When businesses began using computers, they adopted many of the militarys security methods. They established security by using physical controls over access to computers. Alarmed doors and windows, guards, security badges to admit people to sensitive areas, and surveillance cameras were the tools used to secure computers. Back then, interactions between people and computers were limited to the terminals of large mainframe computers. There were very few networks of computers and those that existed did not extend outside the organization to which they belonged. Thus, computer security could be accomplished by managing the activities of the few people who had access to terminals or the computer room.
