WHY INTERNET IS INSECURE 3D VIEWING?
Internet is an open medium. it is an universal medium.
The internet is definitely an open n/w. once data is transmitted
beyond the organizational network, it may be handled by any number
of different intermediate computers(called routers) which make sure
the data is delivered to its intended destination.
It’s the protocols:
The primary protocol of the internet is TCP/IP. It contains Five Layers.
Application Layer
Transport Layer
Internet Layer
Link Layer
Physical Layer
There is no weakness in protocol side.
INTERNET IS INSECURE BECAUSE
Theft of Personal information
If you use the Internet, you may be facing grave danger as your personal information such as name, address, credit card number etc. can be accessed by other culprits to make
your problems worse.
Spamming
Spamming refers to sending unwanted e-mails in bulk, which provide no purpose and needlessly obstruct the entire system. Such illegal activities can be very frustrating for you,and so instead of just ignoring it, you should make an effort to try and stop these activities so that using the Internet can become that much safer.
INTERNET SECURITY HOLES ?
Emergence of Cyber Crime
Unfortunately, not all of you are using the Internet in a positive way.
The Internet has not only allowed you to communicate around the
world, it has also opened up the doors for electronic crime.
The Computer Security Institute’s (CSI’s) 2002 Computer Crime and
Security Survey raised the level of awareness and aided in
determining the scope of cyber crime.
This survey of large corporations revealed that 73 percent of the
respondents detected the unauthorized use of their computer
systems in the last year.
During the past few years, the most serious financial losses due to
attacks have occurred through theft of proprietary information and
financial fraud, according to CSI.
Sixty-nine respondents in CSI’s 2002 Computer Crime and Security
Survey reported a total loss of $99,019,000 in theft of proprietary
information while 87 respondents reported a total loss of
$88,229,000 in financial fraud.
