Computer hacking involves invading someone else’s
computer
A virus is a program written to cause the corruption of data
A worm makes copies of itself and slows down a PC
A time bomb causes damage at a time in the future
A Trojan horse is harmful software that does the unexpected
An e-mail virus uses e-mail messages to carry the virus

Theft of computer time is a crime committed
regularly in the workplace
Changing data before or after it is entered into the
computer is called data diddling
Computer equipment and data are subject to
hazards such as fire and flood
Illegally copying and using software is called
software piracy
Working on computers for long periods of time can
cause ergonomic-related health issues

Information submitted on the Internet can be used in
computer crime
The best way to protect data is to control access of
the data, most often through passwords
Other security measures include using ID cards,
firewalls, antivirus software, selective hiring
practices, and data backups
Biometric security measures examine a
fingerprint, a voice pattern, or the iris or retina of the
eye and compare them against employee records

Computer security is necessary to keep hardware,
software, and data safe from harm or destruction.
The most common way to control access to data is
to use passwords.
Illegally copying and using software is called
software piracy. It has cost companies millions of
dollars in lost sales.
Laws have been passed in an effort to assist those
who have been injured by computer crimes and
offenses. Many computer crimes are difficult to prove
and prosecute.
