On the contrary, many of these crimes, such as embezzlement of funds, the alteration of records, theft, vandalism, sabotage, and terrorism, can be committed without a computer. But with a computer, these offenses can be carried out more quickly and
5、with less chance that the person responsible for the crime will be discovered. Computer crimes are on the rise and have been for the last twelve years. Just how much these computer crimes cost the American public is in dispute, but estimates range from $ 3 billion to $ 5 billion annually. Even the F
6、BI, which attempts-to keep track of the growth or decline of all kinds of crimes, is unable to say precisely how large a loss is involved; however, it estimates that the average take from a company hit by computer crime is $ 600,000.

7、(A) more computers in use and, thus, more people who are familiar with basic computer operation; (B) more computers tied together in satellite and other data-transmission networks; and (C) the easy access of microcomputers to huge mainframe data bases.

8、 lead us to believe that most computer crimes are committed by teenage “hackers“ brilliant and basically good children who let their imagination and technical genius get them into trouble. But a realistic look at the crimes reveals that the offender is likely to be an employee of the firm against wh
9、ich the crime has been committed, i. e an “insider“. Difficulty of Detection and Prevention Given the kind of person who commits a computer crime and the environment in which the crime occurs, it is often difficult to detect who the criminal is. First of all, the crime may be so complex that months
10、or years go by before anyone discovers it. Second, once the crime has been revealed, it is not easy to find a clear trail of evidence that leads back to the guilty party. After all, looking for “weapons“ or fingerprints does not occur as it might in the investigation of more conventional crimes. Thi
11、rd, there are usually no witnesses to the computer crime, even though it may be taking place in a mom filled with people. Who is to say if the person at the next terminal, calmly keying in data, is doing the companys work or committing a criminal act? Fourth, not enough people in management and law

A company may not announce the crime out of fear that the pubic will find out the weaknesses of its computer system and lose confidence in its organization. Banks, credit card companies, and investment firms are especia
15、lly sensitive about revealing their vulnerabilities (脆弱性 ) because they rely heavily on customer trust. To avoid public attention, cautious companies will often settle cases of computer tampering out of court. And if cases do go to trial and the offenders are convicted, they may be punished only by
16、a fine or light sentence because the judge or jury isnt fully trained to understand the nature and seriousness of the crime. Not all companies are timid in apprehending computer criminals. For example, Connecticut General Life Insurance Company decided it had to get tough on violators. So when the c
17、ompany discovered that one of its computer technicians had embezzled $ 200,000 by entering false benefit claims, it presented it findings to the states attorney and aided in the prosecution of the technician.
