 Computer security basically
is the protection of
computer systems and
information from harm,
theft, and unauthorized

 It is the process of
preventing and detecting
unauthorized use of your
computer system.

computer security which is
widely used to protect the
valuable information of an

 Computer security threats
 Computer security
threats are possible dangers
that can possibly hamper
the normal functioning of
your computer.
 In the present age, cyber
threats are constantly
increasing as the world is
going digital.
 The most harmful types of
computer security are:

Viruses
6
 A computer virus is a
malicious program which is
loaded into the user’s
computer without user’s
knowledge.
 It replicates itself and
infects the files and
programs on the user’s PC.
 The ultimate goal of a virus
is to ensure that the
victim’s computer will never
be able to operate properly
or even at all.

Computer
Worm
7
 A computer worm is a
software program that can
copy itself from one
computer to another,
without human interaction.
 The potential risk here is
that it will use up your
computer hard disk space
because a worm can
replicate in greater volume
and with great speed.

8. SURBHI SAROHA
Botnet
8
 A botnet is a group of
computers connected to the
internet, that have been
compromised by a hacker
using a computer virus.
 An individual computer is
called ‘zombie
computer’. The result of
this threat is the victim’s
computer, which is the bot
will be used for malicious
activities and for a larger
scale attack like DDoS.

9. SURBHI SAROHA
Rootkit
9
 A rootkit is a computer program
designed to provide continued
privileged access to a computer
while actively hiding its presence.
 Once a rootkit has been installed,
the controller of the rootkit will
be able to remotely execute files
and change system configurations
on the host machine.

10. SURBHI SAROHA
Keylogger

 Also known as a keystroke logger,
keyloggers can track the real-time
activity of a user on his computer.
It keeps a record of all the
keystrokes made by user

common security threats
that you’ll come across.
Apart from these, there are
others like spyware,
wabbits, scareware,
bluesnarfing and many
more.
 Fortunately, there are ways
to protect yourself against
these attacks.

12. SURBHI SAROHA
The
Marketplace
for
vulnerabilities
12
 Vulnerable consumers fail to
understand their preferences
and/or lack the knowledge,
skills, or freedom to act on
them.
 The aim is to significantly
replace trial and error with a
robust understanding
of markets, markets habitu
ally governed by social
virtues.
 Vulnerable consumers
cannot navigate the
marketplace.

Vulnerable consumers fail to
understand their preferences
and/or lack the knowledge,

To protect them, some want to
censor information, restrict
choices, and mandate
behaviors.
