Every human discovery has pros and cons, so is the computer which has pervaded all our lives. The modern humanity is increasingly dependent on computer for various day-to-day activities. Computers do us a whole lot of good things, but it is not without some pitfalls. With the extensive use of internet for hundreds of our needs, computer opens a vicious cycle of hackers. Computer hacking
is a term which refers to an individual’s illegal and unauthorized
access to the data which are stored in a user’s system. This is done to
disturb the confidentiality and security of the user’s computer.
The hackers focus on individuals’ computer system when they are online.
As long as you are not connected to internet you are less prone to hacking. The access to internet has actually made computer hacking
easy. You must protect your computer with strong antivirus and firewall
programs to keep hackers away. Hackers are known for creating problems
which are difficult to solve. This gives a good business to computer
investigators and technicians. Hacking can be done in lots of ways. Few of them are given below:
- Worms: These are the programs which propagate through networks.
- Trojans: These are hidden in websites, attached files and emails.
- Viruses: These attach themselves to various kinds of files. They can damage certain functions of your computer.
Hackers also crash on wireless networks which do not have firewall
installed and enabled. They can also send email attachments with
malicious software which get embedded on the victim’s computer. Hackers
attack accounts which have weak passwords. All these are done to get
access to confidential and sensitive information of the users. Whatever
is the method of hacking, the effect is harmful for the user. Your system will be flooded with viruses, malwares which steal your information. In order to avoid hacking
one has to make sure that the systems at home or office have the latest
anti-virus program and firewall installed and enabled. These programs
need to be regularly updated. Use the latest browser and scan your
computer on a regular basis.
New Age...
The New Age
of internet has brought with it many risk factors along with umpteen
advantages. The New Age is the time where our personal lives are no
longer very personal, but people are able to access personal information
of internet users from various sources in the virtual world.
We need to be careful about usernames and passwords, else it will lead
to dangerous consequences. Universities, large companies and government
agencies are mostly targeted by hackers
simply because of the bulk of information they handle. The great
newspapers like The Wall Street Journal and The New York Times were also
targeted by hackers.
Computer hackers are people who gain remote access to information stored
in a system elsewhere. During the 1950s and 60s hackers were more drawn
towards learning the operations of a computer rather than stealing
confidential information of a remote user. Unlike the olden days, now
computer hacking has become more sophisticated and organized. In the
late 1990s hackers tried to get access to files in the network of
Pentagon. Some more expert hackers gained access to the patent files at
the Indiana University School of Medicine in February 2003. Many hackers
were sentenced in the history since hacking represents a potential national security threat.
Viruses
One major tool hackers use to steal information from computer systems is the use of viruses. Over the years the number of viruses has increased drastically. The virtual world now has above 100000 viruses
and the number grows virtually every day. Apart from the threat the
computer hackers pose, they also can be beneficial in one way. They can
bring to light the flaws in a computer network. Hackers can help in
redesigning the system and in making information inaccessible to illegal
users and to unauthorized access.
Getting Administrative Access
Getting a log in password is one of the predominant ways to get access
to a computer which is by the side of the hacker. Getting remote access
to a computer is another way to hack a system. Managing to crack a Wi-Fi
password is the third method of sneaking into someone else’s system. Hacking
if done on a public or school computer will have serious consequences.
The hacker will be put behind the bars for illegally accessing the
computer which does not belong to him or her.
