单选题
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. The computer criminals who have been
caught may have been the victims of uncommonly bad luck. Unlike
other lawbreakers, who must leave the country, commit suicide, or go to jail,
computer criminals sometimes escape punishment, demanding not only that they not
be charged but that they be given good recommendations and perhaps other
benefits. All too often, their demands have been met. Why?
Because company executives are afraid of the bad publicity that would result if
the public found out that their computer had been misused. They hesitate at the
thought of a criminal boasting in open court of how he juggled (诈骗) the most
confidential (保密) records right under the noses of the company's executives,
accountants, and security staff. And so another computer criminal departs with
just the recommendations he needs to continue his crimes elsewhere.
