2. What is Cyber
Security?
Cybersecurity protects systems, networks, and programs from
digital attacks, damage, or theft. These cyberattacks usually
target accessing, changing, or destroying sensitive information;
extorting money from users through ransomware; or interrupting
normal business processes.

1. Phishing Attacks
3. Ransomware
4. Cryptocurrency Hijacking
5. Botnet Attacks
Some Common Types
Of Cyberattacks

4. • Cybercrime is easily achievable for those with advanced hacking skills.
Why Cyber Crime
increasing day by day?
• There is a lower risk of getting caught in Cybercrime.
• Cyber attackers can get huge amounts of money for their little work.
• Cyber attackers can target thousands of victims.
• Cryptocurrencies have made money laundering easier.

5. IDS
• Intrusion Detection Systems
• Detect only intrusions, but
unable to prevent intrusions
• Monitoring system
• Requires a human or another
system to look at the results
IPS
• Intrusion Prevention Systems
• Detect as well as prevent
intrusions
• Control system
• Requires only a regularly updated
database with the latest threat
data

6. • Information security
• Network security
• Operational security
• Application security
• End-user security
• Business continuity

The key elements
of Cyber Security

7. It is used to
provide privacy
and prevent
unauthorized
access to data.

WHAT IS THE MAIN GOAL
OF CYBER SECURITY?
This ensures the data
is genuine, correct, and
safe from unwanted
threat actors or
unintentional user
alteration.
INTEGRITY
It ensures that
the information
is constantly
available and
accessible
AVAILABILITY

8. • Cyber security protects online businesses and
transactions against ransomware, malware, online
fraud, and phishing.
• It protects the end-users.
• It provides great protection for both data as well as
networks.
• It can increase the recovery time after a breach.
• It prevents unauthorized users from accessing
sensitive information.
The main advantages of
cyber security

9. WHAT IS
CRYPTOGRAPHY?
It is used to protect information from third
parties called adversaries. It is a method of
protecting information and communications
through codes so that only those for whom the
information is intended can read and process
the data.

10. WHAT DO YOU
UNDERSTAND BY THE CIA
TRIAD?
CIA is an acronym that stands for Confidentiality,
Integrity, and Availability. It is commonly known as
the CIA triad. CIA is a model that specifies the guide
policies for Information Security. It is one of the
most popular models used by organizations.

11. The main usage of Firewalls is to protect the
system/network from viruses, worms, malware,
threats etc. Firewalls can also be used to prevent
remote access and content filtering.

OF?

12. WHAT DO YOU UNDERSTAND
BY VA AND PT?
VA or Vulnerability Assessment
is the process of finding
vulnerabilities or flaws in the
target. In this process, the
organization already knows
that its system/network has
flaws or weaknesses and wants
to find these flaws and
prioritize fixing them.
PT or Penetration Testing is the
process of deep searching and
finding vulnerabilities on the
target. In this process, the
organizations set up all the
possible security measures they
could think of and test if there is
any other way their
system/network can be hacked.

13. WHAT IS A VPN AND ITS USE
IN CYBER SECURITY?
VPN - It is an acronym that stands for Virtual Private
Network. It creates a safe encrypted tunnel across the
internet by connecting a VPN server to a VPN client.
Use - Suppose a user has a VPN client installed on their
machine. The VPN client then creates an encrypted
tunnel to the VPN server, and the user can securely
send or receive information over the internet.
