Concluding remarks
Crime committed using a computer and the internet to steal a
person's identity or illegal imports or malicious programs
Cybercrime is nothing but where the computer used as an object
or subject of crime.
The first spam email took place in 1978 when it was sent out over the
Arpanet (Advanced Research Projects Agency Network),.
The first virus was installed on an Apple computer in 1982 when a
high school student, Rich Skrenta, developed the Elk cloner.
Those who are doing crimes by using the computer as an target or
object.
i. Children and adolescents between the age group of 6 – 18 years
ii. Dissatisfied employees
iii. Professional hackers / crackers
iv. Organized hackers
Unauthorized access to computer systems or networks:
This is generally referred as ‘Hacking’. That is accessing the
information of others without proper authorization.
Theft of information contained in electronic form:
This includes theft of information stored in computer hard disks,
removable storage media etc.
Data diddling:
This is altering raw data just before a computer processes it and
then changing it back after the processing is completed.
Denial of Service attack:
The computer is flooded with more requests than it can handle which
cause it to crash. Distributed Denial of Service (DDOS) attack is a
example.
Trojan attacks:
It means unauthorized programmer. It gains control over another’s
system by representing itself as an authorized programmer.
Web jacking:
This term is derived from the term hi jacking. In these kinds of offences
the hacker gains access and control over the web site of another.
Email bombing:
It refers to sending large numbers of mail to the victim, which
may be an individual or a company by ultimately resulting into
crashing.
The Cyber crimes are categorized as the following
i. Cyber crimes against persons
ii. Cyber crimes against Individual Property
iii. Cyber crimes against government
Under these categorize there are many ways to done Crimes. Here let
we see some ways …
i. Harassment via e-mails:
Harassment through e-mails is not a new concept. It is very similar
to harassing through letters.
ii. Cyber-stalking :
Cyber stalking involves following a person movements across the
Internet by posting messages.
iii. Email spoofing:
A mail which misrepresents its origin. It shows it's origin to be
different from which actually it originates.
i.Computer Vandalism:
Damaging or destroying data rather than stealing or misusing them is
called cyber vandalism.
ii.Transmitting virus:
These are programs that attach themselves to a file and then
circulate .
They usually affect the data on a computer, either by altering or
deleting it.
Cyber Terrorism:
Terrorist attacks on the Internet is by distributed denial of service
attacks, hate websites and hate emails, attacks on sensitive computer
networks, etc. Technology savvy terrorists are using 512-bit encryption,
which is impossible to decrypt.
The recent example may be cited of – Osama Bin Laden, the LTTE, and
attack on America’s army deployment system during Iraq war.
i. Child Pornography:
The use of computer networks to create, distribute, or access
materials that sexually use underage children.
ii. Cyber Contraband:
Transferring illegal items through the internet (such as encryption
technology) that is barred in some locations.
iii. Cyber laundering:
Electronic transfer of illegally-obtained money with the goal of hiding
its source and possibly its destination.
iv. Cyber Stalking:
Threats that creates fear through the use of computer technology such
as email, phones, text messages, webcams, websites or videos.
v. Cyber Theft:
Using a computer to steal. This includes activities related to: breaking
and entering, unlawful appropriation, identity theft, fraud, malicious
hacking and piracy.
Cyber security involves protection of sensitive personal and
business
information through prevention, detection, and
response to different online attacks.
Cyber security actually protects your personal information by
responding, detecting and preventing the attacks.
Privacy policy :
Before submitting your name, email address, or other personal
information on a web site, look for the site's privacy policy.
Evidence that your information is being encrypted :
To protect attackers from hijacking your information, any personal
information submitted online should be encrypted. Many sites use SSL
or secure sockets layer, to encrypt information.
Keep software up to date:
If the seller releases patches for the software operating your device,
install them as soon as possible. Installing them will prevent attackers
from being able to take advantage.
Use good passwords:
Select passwords that will be difficult for thieves to guess. Do not
choose options that allow your computer to remember your
passwords.
Disable remote connectivity:
Some PDA’s and phones are equipped with wireless technologies,
such as Bluetooth, that can be used to connect to other devices or
computers. You should disable these features when they are not in
use.
Let us conclude that…….
Cybercrime is indeed getting the recognition it
deserves.
However, it is not going to restricted that easily.
In fact, it is highly likely that cybercrime and its
hackers will continue developing and upgrading to
stay ahead of the law.
So, to make us a safer we must need cyber
security.
Thank You very much…..
