3. Before we start
Understanding the term CYBER
It is a combining form
relating to information
technology, the internet
and virtual reality
relating to or characteristic of the
culture of computers, information
technology, and virtual reality -
Google
Cyber came from cybernetics
In the late 1940s, cybernetics arose
as the study of control systems and
communications between people
and machines. Today, it has
evolved into a transdisciplinary
approach to regulatory systems.

program that loaded onto computer
without one's knowledge and runs
against/without user permission

7. “
A computer virus is a type
of computer program that, when
executed, replicates itself by modifying
other computer programs and inserting
its own code. When this replication
succeeds, the affected areas are then
said to be "infected" with a computer
virus..

 Removing a computer virus or spyware can be difficult without the
help of malicious software removal tools. Some computer viruses and
other unwanted software reinstall themselves after the viruses and
spyware are detected and removed. Fortunately, by updating the
computer and by using malicious software removal tools, you can
help permanently remove unwanted software.
 Install a security suite that protects the computer against threats such
as viruses and worms
 Install latest update of OS and Antivirus

10. 2. Malware
software that is specifically designed to
disrupt, damage, or gain unauthorized
access to a computer system.

11. “
Malware is the collective name for a
number of malicious software variants,
including viruses, ransomware and
spyware. Shorthand for malicious
software, malware typically consists of
code developed by cyber attackers,
designed to cause extensive damage to
data and systems or to gain unauthorized
access to a network. 11

12. Types of Malware
12
 Spyware: No surprise here — spyware is malware designed to spy on you. It hides in the
background and takes notes on what you do online, including your passwords, credit card
numbers, surfing habits, and more.
 Worms: Worms infect entire networks of devices, either local or across the internet, by
using network interfaces. It uses each consecutively infected machine to infect others.
 Ransomware: This kind of malware typically locks down your computer and your files,
and threatens to erase everything unless you pay a ransom.
 Adware: Though not always malicious in nature, aggressive advertising software can
undermine your security just to serve you ads — which can give other malware an easy
way in. Plus, let’s face it: pop-ups are really annoying.
 Botnets: Botnets are networks of infected computers that are made to work together
under the control of an attacker.

13. How to protect against malware
13
 Don’t trust strangers online! “Social engineering”, which can include strange emails,
abrupt alerts, fake profiles, and curiosity-tickling offers, are the #1 method of delivering
malware. If you don’t know exactly what it is, don’t click on it.
 Double-check your downloads! From pirating sites to official storefronts, malware is often
lurking just around the corner. So before downloading, always double-check that the
provider is trustworthy by carefully reading reviews and comments.
 Get an ad-blocker! Malvertising – where hackers use infected banners or pop-up ads to
infect your device – is on the rise. You can’t know which ads are bad: so it’s safer to just
block them all with a reliable ad-blocker.
 Careful where you browse! Malware can be found anywhere, but it’s most common in
websites with poor backend security, like small, local websites. If you stick to large,
reputable sites, you severely reduce your risk of encountering malware.

14. 3. Trojan Virus
is any malware which misleads users of
its true intent.

15. “A Trojan horse or Trojan is a type of malware that
is often disguised as legitimate software. Trojans
can be employed by cyber-thieves and hackers
trying to gain access to users' systems. Users are
typically tricked by some form of social
engineering into loading and executing Trojans on
their systems. Once activated, Trojans can enable
cyber-criminals to spy on you, steal your sensitive
data, and gain backdoor access to your system.
15

16. These actions can include:
16
 Deleting data
 Blocking data
 Modifying data
 Copying data
 Disrupting the performance of
computers or computer networks

17. 5. Hacker
a person who uses computers to gain
unauthorized access to data.

18. “
A hacker is an individual who uses computer,
networking or other skills to overcome a technical
problem. The term hacker may refer to anyone
with technical skills, but it often refers to a person
who uses his or her abilities to gain unauthorized
access to systems or networks in order to commit
crimes. A hacker may, for example, steal
information to hurt people via identity theft,
damage or bring down systems and, often, hold
those systems hostage to collect ransom.
18

19. White
A hacker who uses hacking
skills to protect organizations
from threat actors is called as a
“white hat hacker.” They
actively search for
vulnerabilities in a security
system so that the flaws can be
patched before a cybercriminal
can take advantage of them to
penetrate the system
Types of Hackers
Black
black hat hackers usually have
extensive knowledge about
breaking into computer
networks and bypassing
security protocols. They are
also responsible for
writing malware, which is a
method used to gain access to
these systems.
19
Grey
These types of hackers are
not inherently malicious with
their intentions; they’re just
looking to get something out
of their discoveries for
themselves. Usually, grey hat
hackers will not exploit the
found vulnerabilities.
However, this type of hacking
is still considered illegal
because the hacker did not
receive permission from the
owner prior to attempting to
attack the system.

20. Role of a White Hat Hacker
⬡ Scanning ports to identify flaws – White hat hackers use port scanning tools (such
as Nessus or Nmap) to find whether there are any open ports. They study these
ports in detail to come up with countermeasures to defend them against
cyberattacks.
⬡ Examine patch installations – They also examine patch installations so that threat
actors can’t exploit them.
⬡ Social engineering methods – They use social engineering methods, such as
shoulder surfing, to collect crucial information. The steps that can help any
cybercriminal to gain access to sensitive data.
⬡ Dodge honeypots, IDS, or other systems – White hat hackers also try different
methodologies and approaches to evade honeypots set up by the organization.
They look for loopholes that can give black hats the access to avoid firewalls,
IDS/IPS ((Intrusion Detection Systems/Intrusion Prevention Systems), or
honeypots.
⬡ Sniffing – They also perform network sniffing, hijacking web servers, and other
network-related loopholes.

In India on an average a certified ethical hacker earns an
average salary of Rs 3,67,249 per year

22. “We can never stop a
Hacker to hack something
the only thing we can do to
protect computers is
Creating HURDLES for the
Hacker. 22

23. Why are we and organizations are
hiring hacking to hack our own
systems?
23
To catch a thief, you must think like a thief. That’s the basis for ethical hacking. Knowing
your enemy is absolutely critical and very important. This may help you in creating the
strategy for catching the hackers in the system. We try to hack our own systems so that we
will be able to know the loop holes in the administration. This will help you in making
precautions. You don’t have to protect your systems from everything. You can’t. The only
protection against everything is to unplug your computer systems and lock them away so no
one can touch them — not even you. But doing so is not the best approach to information
security, and it’s certainly not good for business. What’s important is to protect your systems
from known vulnerabilities and common attacks, which happen to be some of the most
overlooked weaknesses in many organizations.

24. Your overall goals as an ethical
hacker are to
24
 Prioritize your systems so you can focus your efforts on what
matters.
 Hack your systems in a nondestructive fashion.
 Enumerate vulnerabilities and, if necessary, prove to
management that vulnerabilities exist and can be exploited.
 Apply results to remove the vulnerabilities and better secure
your systems.

25. Why Is
Cybersecurity
Important for
New
Entrepreneurs?

26. As we move forward in the
digital age, cybersecurity
should be a core business
objective, no matter how
large or small your business
is — and being proactive can
only protect you. Make it a
priority today.

27. “
If you know the enemy and know yourself, you need
not to fear the results of a hundred battles. If you
know yourself but not the enemy , for every victory
gained you will also suffer a defeat. If you know
neither the enemy nor yourself, you will succumb in
every battle.”
In the world of cyber – You Neither Know Your Enemy
Nor Yourself!
