 o A computer crime is a crime like any other crime, except 
that in this case the illegal act must involve a computer 
system either as an object of a crime, used to commit a 
crime, or a repository of evidence related to a crime.o Expanded de ni on
 o an illegal act that involves a computer system or computer
related system like a telephone, microwave, satellite or 
other telecommunica ons system that connect one or 
more computers or computer-related systems
 For a variety of reasons computer crimes target computer 
resources:- Hardware, like computers, printers, scanners, servers, and 
communica on media.- Soware, that includes applica on and special programs, system 
backups, and diagnos c programs, and system programs such as 
opera ng systems and protocols.- Data in storage, transi on, or undergoing modi ca on- People that include users, system administrators, and hardware and 
soware manufacturers.- Documenta on, that includes user informa on for hardware and 
soware, administra ve procedures, and policy documents.- Supplies, that include paper and printer cartridges
An a ack on any one of these resources is considered a computer or 
computer-related a ack.Most computer a acks on the resources above fall into the 
three categories:- Natural or involuntary a ack, which includes accidents origina ng from 
natural disasters such as re, oods, windstorms, lightning, and earthquakes, 
and which usually occur very quickly without warning and are beyond human 
capacity, o en causing serious damage to a ected cyberspace resources.- Human blunders, errors, and omissions, that are usually caused by 
uninten onal human ac ons.Malfunc ons, though 
occurring more frequently than natural disasters, are as unpredictable as 
natural disasters.- Inten onal threats, that originate from humans caused by illegal or criminal 
acts from either insiders or outsiders, recrea onal hackers, and criminals.o Expanded de ni on
