UNIT 32 P1 - Describe how networks can be attacked
A computer
virus is a program that duplicates itself and it spreads itself from computer
to computer through the internet. There are many types of Malware and this
includes computer viruses such as; Viruses, worms, Trojans, and bots. Viruses
have a number of ways to ruin a computer, but most viruses mainly fill up the
hard disk space of a computer filing it with useless information which will
prevent you from being able to access space you would need in future. When a computer
becomes infected by a virus, the virus makes your system slow down tremendously
which would lead to software from stop responding, freezes or even corrupting
files. Viruses can also automatically make pop ups on your screen faster than
you could exist them. If an organisation fell victim to viruses like this, the
organisation would have a big problem because their storage will fill up with
useless information so they wouldn’t be able to provide a service to the
standard the normally preform at nor will they have space for the information
that they might need to be saved in
Hacking:
Hacking can
either be a hobby or a career in using vulnerabilities in computers or servers
to breach into computer systems or websites.
When a hacker weaves their way through a computer system, it is normally
to amuse them, to challenge or to compete with other hackers to see who the
best is. Hacking is rarely for personal gain, but none the less some hackers
have been known to hack into systems to gain profits. The harder a system is for
a hacker the more willing they are to hack into the system to prove to
themselves. The impact a computer hacker has when they’ve hacked into a
computer systems security is immense because they would be able to read, edit, and expose personal
data which then puts their privacy at risk. This may also put people at risk of
credit card fraud which could be used by the people who hacked in to go on a
shopping spree. On the national news there have been many cases where phone
hacking acquire information on confidential political information. This kind of hacking effects politics as
people are able to gain information before it is ready to be released to the
public. This would also give upper hand to any country if they gain valuable
information from other counties.
DDOS
A Denial of
service (Dos) attack is an attack to make a computer or network service
unavailable to users. The main reason
why they would do this is because they want to shut down a system so the user
wouldn’t be able to use their system. This attack is done by someone sending
allot of useless traffic to a website to a point where the server would not be
able to handle the traffic and crashes. The effect this would have on an e-commerce
business is huge because the company would have to work hard and pay allot of
money to get it shorted, this would also mean if the business was a product
selling company that they would also be losing the profits they could of made.
This would also make customers worried that their financial information could
be at risk.
