Ngozi is a 12-year-old girl who lives in Enugu. She loves chatting with her friends and playing games on her mother's phone. One Saturday, something terrible happened.
Ngozi's mother opened her bank app and could not log in. A message appeared: "Wrong password. Try again." She tried again. Wrong again. She tried one more time. Wrong again. The account was locked.
"Something is wrong," her mother said. "I always use the same password."
Ngozi looked at her mother. "Maybe someone changed it, Mama."
The next day, they went to the bank. The bank manager checked the records. Someone had logged into the account from a strange city and taken out all the money.
"How did this happen?" Ngozi's mother asked.
"Do you share your password with anyone?" the manager asked.
"No, never," her mother said.
"Do you use the same password for other websites?"
Her mother paused. "Yes. For my email, my Facebook, my bank. The same password."
The manager sighed. "That is the problem. If a hacker learns your password on one website, they try it on every other website. It is called password reuse."
Ngozi listened carefully. She had learned something important. A simple mistake — using the same password everywhere — had cost her family everything.
From that day, Ngozi decided to learn more about cybersecurity. She wanted to protect her family and her friends from people who wanted to hurt them.

Ngozi's mother used the same password everywhere. When one website was hacked, the hacker used the password to break into her bank account. This story introduces the whole module.
In this section, you will go through 12 short lessons. Each lesson teaches one big idea. Each lesson ends with a mini summary. Read slowly. Think about the examples. Ask questions. That is how you learn.
Cybersecurity is the work of protecting computers, phones, networks, and information from bad people.
Without cybersecurity, anyone could steal your money, read your messages, or use your identity. Cybersecurity keeps your digital life safe.
Think of your house. You lock the door so strangers cannot enter. Cybersecurity is the lock for your digital life.
When you log into a bank app with a password and a PIN, that is cybersecurity at work.
When a school uses a password to protect student records, that is cybersecurity.
When your family uses a PIN on the Wi-Fi router, that is cybersecurity.
When Nigerian banks send you a one-time password (OTP) before you can send money, that is cybersecurity.
CYBERSECURITY IS A LOCK
=======================
[ Your digital life ]

[ Strangers cannot enter ]
Cybersecurity is the work of protecting computers, phones, networks, and information from bad people.
Cybersecurity matters because our whole lives now live on computers. Money, messages, photos, and personal details are all digital.
If cyber criminals get access, they can steal money, ruin reputations, and cause real harm.
Think of a bank without a security guard. Anyone could walk in and take money. Cybersecurity is the guard for the digital world.
When a company loses customer data to hackers, customers lose trust and the company loses money.
When a school's exam questions are leaked, students' results become unfair.
When a family's WhatsApp account is hacked, private messages are exposed.
When a Nigerian bank's system is hacked, customers lose their savings. This is why banks spend millions on cybersecurity.
WHY CYBERSECURITY MATTERS
=========================
[ Money ] [ Messages ] [ Photos ] [ Personal Details ]
\ | | /
\ | | /
V V V V
[ All digital and need protection ]
Cybersecurity matters because our whole lives are digital. Without it, we lose money and privacy.
Data means information. Your name, age, school, phone number, and photos are all data.
Data is valuable. Cyber criminals want your data because they can sell it or use it to steal from you.
Think of your school file. It holds your name, class, and scores. That is your data.
Your bank account number and PIN are data. If someone gets them, they can take your money.
Your exam scores are data. The school protects them so no one can change them.
Your family photos are data. If a hacker steals them, they can be shared without permission.
Your BVN (Bank Verification Number) is very important data. Never share it with strangers.
DATA IS INFORMATION =================== [ Name: Ngozi ] [ Age: 12 ] [ School: Unity Primary ] [ Phone: 080-1234-5678 ] [ Photo: ngozi.jpg ] All of this is data.
Data is information. It includes your name, age, photos, and secrets. It must be protected.
Privacy means keeping your personal information private. It means controlling who can see or use your data.
Everyone deserves privacy. Without it, strangers can learn everything about you and use it against you.
Think of a diary. You do not want everyone reading it. Privacy is keeping your diary private.
Your password is private. Only you should know it.
Your report card is private. Only your family and teachers should see it.
Your family conversations are private. Only family members should hear them.
Your bank statements are private. Only you should access them.
PRIVACY IS CONTROL
==================
[ You decide who sees your information ]
|
V
[ Friends: Yes ]
[ Strangers: No ]
[ Hackers: Never ]
Privacy means keeping your personal information private. You decide who sees it.
Cyber criminals are people who use computers to do bad things. They steal, cheat, or harm others online.
Knowing how they work helps you stay safe. Most attacks follow simple tricks.
Think of a thief who enters your house through a small window you forgot to lock. Cyber criminals look for small mistakes too.
A cyber criminal sends a fake email pretending to be from your bank. If you click the link, they steal your password.
A cyber criminal pretends to be a classmate online and asks for private details.
A cyber criminal calls pretending to be a family member and asks for money.
Many Nigerians receive fake SMS messages that say, "Your bank account is blocked. Click this link." If they click, they lose money.
CYBER CRIMINALS LOOK FOR WEAK SPOTS
===================================
[ Your digital life ] <-- weak spots? <-- cyber criminal
|
V
[ They try: passwords, fake messages, fake calls ]
|
V
[ If you fall for the trick, they win ]
Cyber criminals use computers to steal or harm. They look for small mistakes to break into your digital life.
A hacker is someone who uses computers to find weaknesses in systems. There are good hackers and bad hackers.
Good hackers help protect systems. Bad hackers break into systems. Knowing the difference matters.
Think of a locksmith. A good locksmith checks your door and says, "This lock is weak, let me help you fix it." A bad locksmith opens your door when you are not home.
Good hackers test bank apps to make sure they cannot be broken into.
Good hackers test school portals to make sure student data is safe.
Good hackers test smart doorbells to make sure they cannot be turned off by strangers.
Nigerian banks hire ethical hackers to test their systems before bad hackers can break in.
GOOD HACKER vs BAD HACKER ========================= Good hacker: [ Find weakness ] --> [ Tell the owner ] --> [ Fix it ] Bad hacker: [ Find weakness ] --> [ Use it to steal ] --> [ Hide ]
Hackers find weaknesses in systems. Good hackers help fix them. Bad hackers use them to steal.
Cyber threats are the different ways cyber criminals try to attack you. Some are simple, some are clever.
Knowing the threats helps you spot them before it is too late.
Think of wild animals in a forest. If you know which ones are dangerous, you can stay safe. Cyber threats are the wild animals of the internet.
You receive an email that says, "You won ₦1,000,000. Click here to claim." It is phishing.
A student receives a message that says, "Your exam score is out. Click this link." The link is fake.
A family receives a call saying, "We are from your bank. Please confirm your PIN." It is a scam.
"Yahoo boys" use phishing emails and fake websites to steal money from people around the world.
COMMON CYBER THREATS ==================== Phishing: [ Fake message ] --> [ You click ] --> [ Password stolen ] Malware: [ Bad download ] --> [ Device infected ] --> [ Data lost ] Ransomware:[ Files locked ] --> [ Payment demanded ] --> [ Big problem ]
Cyber threats include phishing, malware, ransomware, password attacks, identity theft, and fake websites. Learn to spot them.
Many different people work in cybersecurity. Each has a different job. Together, they protect the digital world.
Understanding the roles helps you choose a career path later.
Think of a football team. Each player has a role. Cybersecurity teams are the same.
A bank has a team of security analysts who watch for strange activity every day.
A school hires a security consultant to check if the student portal is safe.
A family uses a security app that acts like a security analyst for their home Wi-Fi.
Nigerian banks, fintechs, and government agencies employ many cybersecurity professionals.
CYBERSECURITY TEAM
==================
[ CISO ]
|
+-- Security Analyst
+-- Penetration Tester
+-- Security Engineer
+-- Incident Responder
+-- Security Consultant
Cybersecurity has many roles. Each protects the digital world in a different way.
Good habits are simple actions you take every day to stay safe online.
Most cyber attacks succeed because of small mistakes. Good habits stop them.
Think of brushing your teeth. You do it every day without thinking. Good cybersecurity habits should be the same.
A strong password like "Bright-Falcon-47-Jump" is better than "1234".
A student who never clicks strange links will never fall for phishing.
A family that updates its Wi-Fi password every few months is safer.
Never share your OTP with anyone, even if the caller says they are from your bank.
GOOD HABITS =========== Strong password -> Yes Password reuse -> Never Two-factor -> Always Strange links -> Never click Updates -> Always Sharing your OTP -> Never
Good habits stop most attacks. Use strong passwords, avoid strange links, and never share your OTP.
Cybersecurity is not only for big companies. It touches your daily life too.
Every time you use a phone, you are practising or ignoring cybersecurity.
Think of your daily routine. You lock your door, keep your money safe, and protect your secrets. Cybersecurity is the same idea for your phone.
When you use a fingerprint to unlock your phone, that is cybersecurity.
When a school portal asks for your exam number and password, that is cybersecurity.
When your Wi-Fi router uses a password, that is cybersecurity.
When you use USSD to buy airtime and it asks for your PIN, that is cybersecurity.
CYBERSECURITY IN DAILY LIFE =========================== Phone lock -> Yes Bank PIN -> Yes Email password -> Yes Wi-Fi password -> Yes OTP before transfer-> Yes You use cybersecurity every day!
Cybersecurity is part of daily life. Every password, PIN, and OTP is a form of protection.
Myths are false beliefs. Many people believe wrong things about cybersecurity jobs.
Believing myths can stop you from learning or pursuing a career. Learn the truth.
Think of old stories people tell. Some are true. Many are false. Learn to check.
| Myth | Truth |
|---|---|
| You must be a genius to work in cybersecurity. | No. Anyone who is curious and willing to learn can do it. |
| You must know coding first. | No. Many beginners start without coding. |
| Cybersecurity is only for men. | No. Women work in cybersecurity too, and the field needs more of them. |
| It is too hard for children. | No. Children can learn cybersecurity basics easily. |
| You must be a hacker to work in cybersecurity. | No. Many roles do not involve hacking. |
Many cybersecurity professionals started with no technical background.
A student who believes "only geniuses can do it" may give up too soon. The truth is different.
A parent who thinks "cybersecurity is only for men" may not encourage their daughter. That is a mistake.
Many Nigerian women work in cybersecurity. They prove the myth wrong every day.
MYTHS vs TRUTH ============== Myth: [ Genius only ] Truth: [ Anyone curious ] Myth: [ Boys only ] Truth: [ Girls too ] Myth: [ Coding first ] Truth: [ Basics first ]
Many myths surround cybersecurity. Learn the truth so you are not held back.
A cybersecurity thinker is someone who notices dangers online and acts safely.
This skill helps you protect yourself, your family, and your friends.
Think of a careful driver. They watch the road, avoid danger, and stay alert. A cybersecurity thinker does the same online.
When you receive a strange email, a cybersecurity thinker pauses before clicking.
When a student receives a fake exam-result message, they check before clicking.
When a family receives a strange call, they hang up and call the bank directly.
A cybersecurity thinker never shares their OTP, no matter who asks.

[ You understand cybersecurity jobs! ]
This module introduces the main cybersecurity jobs. You will learn what each role does, what skills are needed, and how they work together as a team.
By the end of this module, you will be able to:
You will learn about six main cybersecurity jobs, their responsibilities, skills, and career paths.
Amina is a 12-year-old girl who lives in Abuja. She loves football. One Saturday, her school held a big match against another school. Amina was the team captain.
Before the match, the coach called the team together. "Listen carefully," he said. "Each of you has a role. If you all play your role well, we will win."
He pointed to each player.
"Tunde, you are the goalkeeper. Your job is to stop the ball."
"Chidi, you are a defender. Your job is to protect the goal."
"Fatima, you are a midfielder. Your job is to move the ball and support everyone."
"Musa, you are a striker. Your job is to score."
"And me," the coach said, "I am the coach. I plan the strategy and lead the team."
Amina nodded. She understood. Each player had a role.
The match began. The goalkeeper stopped shots. The defenders blocked attacks. The midfielder passed the ball. The striker scored twice. The coach gave good advice. Together, the team won 2–0.
After the match, Amina thought about it. "The team won because everyone had a role," she said to the coach.
"Exactly," the coach replied. "And cybersecurity teams work the same way. Each person has a role. Together, they keep the systems safe."
AMINA'S FOOTBALL TEAM ===================== [ Goalkeeper ] - Stop the ball [ Defender ] - Protect the goal [ Midfielder ] - Move the ball [ Striker ] - Score [ Coach ] - Lead the team Everyone has a role. Together, they win.
Amina learned that a football team works when everyone plays their role. Cybersecurity teams work the same way. Each person has a different job. This story introduces the whole module.
In this section, you will go through 12 short lessons. Each lesson teaches one big idea. Each lesson ends with a mini summary. Read slowly. Think about the examples. Ask questions. That is how you learn.
The cybersecurity team is a group of people who work together to protect computers, networks, and data.
No single person can protect everything. A team is needed. Each member has a role.
Think of a hospital. Doctors, nurses, and pharmacists each have a job. A cybersecurity team works the same way.
A bank's cybersecurity team has all six roles working together.
A school's IT team has different people looking after the website, network, and student data.
A family protects itself with different habits — passwords, 2FA, and safe browsing.
Nigerian banks and fintechs employ cybersecurity teams with many roles.

A cybersecurity team is a group of people with different roles. Together, they protect the digital world.
A Security Analyst is a person who watches computer systems for signs of attack. They look for anything strange or dangerous.
Attacks often start quietly. A Security Analyst notices them early and stops them before they cause harm.
Think of a security guard at a bank. They watch the cameras and check for anything suspicious. A Security Analyst does the same, but for computers.
A Security Analyst notices that someone is trying to log into a bank account from a strange country. They block the attempt.
