Network
Investigation Toolkit (NIT)
Cyber
crime (Illegal and unauthorized Internet usage) has increased in
recent years due to open communications policy in many countries all
over the world. The initial effort to prevent, curb and detect these
illegal online activities by using content filtering and service
blocking solutions have failed as there are too many back door
paths. Terrorists start to love the Internet and exploit all
possible way of communications among themselves through the
Internet. Politicians start to make use of Internet to spread their
propaganda and message to their supporters. Illegal betting
organizations make use of Internet for illegal transactions. Drugs
and weapons dealers exploit the Internet to close on drug and
weapons smuggling deals. School and universities students download
unauthorized MP3s, Movies and Software from the Internet. More and
more people start to make use of Internet for their own benefits in
all sorts of ways. The “Online Population” has increased
tremendously in recent years.
