6.1. Concept of
cybersecurity
Cybersecurity is the practice of protecting
computer systems, networks, and digital information from theft, damage,
unauthorized access, and cyberattacks.
Cyberattacks occur
every day and can affect individuals, small businesses, and large organizations
around the world. These attacks can cause serious data loss and financial
damage. To stay protected, people and organizations use various methods such as
network security, application security, information security, and operational
security. Therefore, cybersecurity is essential to keep digital information
safe from cyber threats.
Why is
cybersecurity essential for individuals and businesses in Nepal?
Cybersecurity is
essential in Nepal because the use of the internet, online banking, and digital
services is increasing rapidly. It protects individuals’ personal data and
finances from cyber crimes such as hacking and phishing. For businesses, it
helps secure confidential data, prevent financial loss, and maintain customer
trust.
How do your online
activities impact your privacy and security?
Online activities
affect privacy and security because sharing personal information, using weak
passwords, or clicking unknown links can expose data to cyber attacks. Unsafe
behavior may lead to hacking, data theft, or identity misuse. Safe practices
help protect privacy and security.
What are the
responsibilities of a digital citizen?
A digital citizen
should protect personal and others’ data, follow cyber laws, and use the
internet ethically. They should avoid cyber crimes, respect privacy, and
communicate responsibly online. Practicing safe online behavior is also an
important responsibility.
6.2. Concept of
cybercrime
Cybercrime refers to criminal activities
carried out using computers or the internet.
When computers are
used for illegal purposes, they can harm people’s safety, privacy, and
financial security. Cybercrime includes activities such as identity theft,
phishing through fake emails, website attacks, data theft, installing malicious
software without permission, and hijacking social media accounts.
In Nepal, cybercrime
is regulated under the Electronic Transactions Act (ETA), 2063 B.S.,
which helps control cybercrime and enforce laws related to digital offenses.
6.3 Prevention
methods from cybercrime
·
Use
a strong password.
·
Multi-factor
authentication (MFA)
·
Software
updates
·
Authentication
·
Use
of Firewall
Use a strong password.
A password is a set
of alphanumeric characters used to verify a user’s identity.
Using strong and
unique passwords helps protect digital data from cyber threats and unauthorized
access. Passwords should be changed regularly and never shared to prevent
misuse of personal information.
Passwords and
usernames together are known as credentials, which are essential for
accessing emails, websites, and financial accounts.
Keeping passwords
secure helps prevent unauthorized access and misuse of personal information.
Tips to Ensure Passwords are Secure
and Strong
a. Do not use simple sequences such
as 1234 or abcd, as they are easy to guess.
b. Use a combination of uppercase
and lowercase letters, numbers, and special symbols.
c. Avoid using dictionary words or
common terms such as admin or password.
d. Use a longer password. It
should be at least six characters, and longer passwords provide better
security.
e. Do not reuse the same password
for multiple accounts and avoid sharing passwords with others.
Multi-Factor
Authentication (MFA)
Multi-factor
authentication (MFA) is a security method that requires users to provide two
or more forms of verification to access an online account or application.
It adds an extra
layer of security, so even if a password is stolen, unauthorized users cannot
easily access the account.
MFA may require a
password along with a mobile phone, fingerprint, face scan, or other
verification methods.
Types of
Multi-Factor Authentication
- Something
you know
a. Password
b. PIN - Something
you have
a. Smartphone
b. Security badge - Something
you are
a. Biometrics such as fingerprint
b. Voice recognition
c. Retina scan
Software Updates
Keeping the operating
system and applications up to date is very important for cybersecurity.
Regular software
updates fix security vulnerabilities and protect systems from cyber attacks.
Enabling automatic
updates helps prevent attacks that target outdated software.
Authentication
Authentication is the
process of identifying a user, usually by using a username and password.
A strong
authentication system helps ensure that only authorized users can access a
computer system and prevents unauthorized access.
Use of Firewall
A firewall is a
security tool that monitors and filters network traffic to block unauthorized
access to a device or network.
It can be
hardware-based, software-based, or built into an operating system such as
Windows Firewall.
Using a firewall
helps protect systems from unwanted internet traffic, viruses, and cyber
attacks.
6.4 Safe Web
Browsing Techniques
Safe web browsing
techniques refer
to the practices and methods used to browse the internet securely in order to
protect users from cyber threats, malware, data theft, and unauthorized access.
Safe web browsing
techniques help reduce cyber risks and protect users from online threats.
To prevent such
attacks, here are some safe browsing techniques that help minimize cyber
threats:
Use a Secure
Connection
A secure connection
is a private and encrypted communication between a user’s device and a server.
Encryption prevents unauthorized users from viewing or altering data. A secure
connection can be identified by a lock icon or https in the
website address bar. Using a trusted Virtual Private Network (VPN) also
helps protect user privacy while browsing the internet.
Use a Secure
Browser
A secure browser
helps protect user privacy and security while browsing the internet.
It provides features such as private browsing,
tracking protection, ad-blocking, and password management.
Examples of secure

and Brave.
Use a Secure
Search Engine
A secure search
engine is a web-based tool that allows users to search for information on the
internet while prioritizing privacy and security.
It may also filter
harmful or inappropriate websites from search results.
Examples of secure
search engines include Google, Bing, and DuckDuckGo.
Use Secure
Websites
A secure website
protects user privacy and data by using security features such as encryption
and authentication.
A secure website can
be identified by a lock icon or https in the address bar.
Checking the
website’s privacy policy and user reviews also helps ensure that proper
security measures are in place.
6.5 Concept of
Digital Citizen
A digital citizen is
a person who uses the Internet and digital technologies responsibly, safely,
and ethically. A good digital citizen respects others online, protects personal
information, avoids cyberbullying, follows laws, and uses technology to learn,
communicate, and contribute positively to society.
Example: A student
attending online classes, using social media politely, and following
cybersecurity rules is a good digital citizen
To be a good
digital citizen, consider following these guidelines:
- Think Before You Post anything online to avoid
hurting others or sharing harmful content.

and respectful behavior on the internet.
Online behavior and
internet ethics focus on using digital platforms responsibly and ethically in
online communities.
Netiquette is
important for both personal and professional use of the internet on platforms
such as social media, online forums, and messaging apps.
Just like good
manners are important in real life, respectful behavior is equally important in
the online world. The basic principle of netiquette is to treat others online
with respect.
Examples of Good
Netiquette and Online Behavior
- Communicate respectfully with
others online.
- Avoid using offensive or
harmful language.
- Respect privacy and do not
share personal information without permission.
- Avoid spamming or flooding

6.7 Concept of
Digital Footprint and Privacy Online
A digital
footprint is the information record created by an individual’s online
activities. These activities include web searches, social media usage, online
shopping, emails, phone calls, and app usage.
A digital footprint
is also known as a digital shadow or electronic footprint.
All online activities
create digital data that can be used to track a person’s behavior and devices,
which makes privacy an important concern in the digital world.
Types of Digital
Footprints
I. Active Digital
Footprint
An active digital
footprint consists of information that a user knowingly and intentionally
shares online. Since the user provides this information willingly, they are
aware of the footprint being created.
Examples: social media posts, emails, comments, and phone calls.
II. Passive
Digital Footprint
A passive digital
footprint consists of information that is collected without the user’s
direct knowledge. These footprints are harder to control and manage because
they are often gathered automatically.
Examples: web searches, online shopping history, location data, website
cookies, and fitness tracker data.
Online privacy refers to the protection of an
individual’s personal information and communications on the internet. It
involves safeguarding data from unauthorized access and misuse. Although
digital technology offers many benefits, it also increases the risk of privacy
breaches due to digital footprints.
Advantages of
Digital Footprints
a. Health Monitoring
Smartwatches and health applications use digital footprints to track and
analyze fitness and health data, helping in better health management.
b. Social Connections
Digital footprints help people connect and communicate with others through
social networking platforms.
c. Targeted Advertising
Companies use browsing behavior to show relevant advertisements, which can
improve customer engagement and sales.
d. Law Enforcement Support
Law enforcement agencies use digital footprints to assist in investigations,
prevent crimes, and ensure public safety.
Disadvantages of Digital Footprints
a. Security Vulnerabilities
Digital footprints can expose users to security risks, leading to privacy
breaches and identity theft.
b. Legal and Ethical Concerns
The use of digital footprints raises legal and ethical issues related to
privacy rights and data protection.
c. Exploitative Business
Practices
Some businesses misuse or sell user data without proper consent, raising
concerns about fairness and ethics.
d. Cybercriminal Exploitation
