These statistics may underestimate the real situation as many organizations or individuals may be unaware that the security of their computer has been compromiseD、Just how much these computer crimes cost theAmerican public is in dispute, but estimates range from $3 billion to $5 billion annually.Even the FBI, 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.A、number of reasons are given for the increase in computer crime:

ManyCNI systems which were once isolated are now connected to the internet, increasing their vulnerability.
There has been speculation over the prospect of terrorists using electronic attacks to target computer systems and networks.According to the National Infrastructure SecurityCoordinationCentre (NISCC、, the probability of terrorists carrying out an electronic attack against theCNI is currently low compared with other risks such as using explosive devices.
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 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.
