Paul could not sleep last night. He woke up early and sat up, and then lay down again. He felt terrible. "I must be sick," he thought, "but I must study for that test." He got up and looked for his history notebook. He finally found it under a pile of clothes on his chair. He went over his history notes, but he couldn’t remember any of the facts in his notes. "What shall I do" he thought.
Just then the telephone rang. He put down his notebook and picked up the telephone. "Good morning," Jack’s voice said. "You must be wrong about that test." "What do you mean" Paul asked weakly. "We’re not going to have a test today." Jack said, "I wrote down the date in my notebook. The test will be next Wednesday; it isn’t today. How do you feel this morning" "Fine," said Paul, "just fine!" Suddenly he really felt fine.
More and more, the operations of our
businesses, governments, and financial institutions are controlled by
information that exists only inside computer memories. Anyone clever enough to
modify this information for his own purposes can reap big reward. Even worse, a
number of people who have done this and been caught at it have managed to get
away without punishment. It’s easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected. But it’s disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures.
