WHAT IS CYBER CRIME ?

form of crime where the Internet or

computers are used as a medium to

commit crime.

National Research Council,

"Computers at Risk",

1991.

"The modern thief can steal more with

a computer than with a gun.

Tomorrow's terrorist may be able to do

more damage with a keyboard than

with a bomb".
