Welcome to Module One of the Cybersecurity for Small Businesses course!
Have you ever helped your parents run a small shop? Maybe your mother sells food at the market. Maybe your father has a small computer repair business. Maybe your uncle sells clothes online. These are all small businesses.
Small businesses are important. They help families earn money. They help communities grow. They help countries like Nigeria become stronger.
But small businesses also face dangers. There are bad people on the internet. These people are called hackers. Hackers want to steal money. They want to steal information. They want to cause problems.
Cyber security is the practice of keeping your business safe from hackers. It is like locking the door of your shop at night. It is like keeping your money in a safe place. It is like not telling strangers your secrets.
Imagine you have a small shop. You sell beautiful clothes. You keep your money in a box under the counter. You lock the shop at night. You have a guard at the door. That is security for your physical shop.
Now imagine your shop is online. You sell clothes on your website. You keep customer information on your computer. You use the internet to receive payments. You need security for your online shop too. That is cyber security.
In this module, you will learn what cyber security is. You will learn why it matters for small businesses. You will learn about the dangers that small businesses face. You will learn simple things you can do to stay safe.
You do not need to be a computer expert. You just need to be curious and ready to learn. By the end of this module, you will understand how to protect a small business from cyber threats.
Let us begin this exciting journey together!
After completing this module, you will be able to:
Once upon a time, in the busy city of Onitsha, Nigeria, there lived a woman named Mama Ngozi. Mama Ngozi had a small fashion shop. She sold beautiful clothes, shoes, and bags.
Mama Ngozi's shop was very popular. Many people came to buy from her. She had many customers. She made good money.
One day, Mama Ngozi decided to start selling online. She created a website. She posted pictures of her clothes. She added a payment option so customers could pay with their bank cards.
At first, everything was good. Customers from all over Nigeria bought from her website. Mama Ngozi was very happy.
Then one day, something terrible happened. Mama Ngozi received an email. The email said, "Your website has a problem. Click here to fix it."
Mama Ngozi was worried. She clicked on the link. The link took her to a website that looked like her website. It asked for her username and password. She entered them.
The next day, Mama Ngozi tried to log in to her website. She could not. Her password did not work. She tried again. It still did not work.
Then she received another email. It said, "We have taken over your website. Pay us 500,000 naira, or we will delete everything."
Mama Ngozi started to cry. Her website was gone. All her customer information was gone. All her product photos were gone. She had lost everything.
Her son, Emeka, came to visit. He saw that his mother was crying.
"Mama," he said, "what is wrong?"
Mama Ngozi told him what happened. Emeka listened carefully.
"Mama," Emeka said, "you have been a victim of a phishing attack. The email was fake. The website was fake. They tricked you into giving them your password."
Mama Ngozi was confused. "What is phishing?" she asked.
Emeka explained. "Phishing is when bad people pretend to be someone you trust. They send you a fake email. They try to trick you into giving them your password or money."
Mama Ngozi understood. She had been tricked. She had not been careful.
Emeka helped his mother. They called a cyber security expert. The expert helped them get the website back. They changed all the passwords. They trained Mama Ngozi and her workers about cyber security.
Mama Ngozi learned a very important lesson. Cyber security is important for small businesses. If you are not careful, you can lose everything.
From that day on, Mama Ngozi was very careful. She never clicked on strange links. She used strong passwords. She trained her workers. Her business grew and grew.
And that is exactly what you will learn in this module.
Cyber security is the practice of keeping computers, phones, networks, and data safe from bad people. It is all the things you do to protect your business from hackers.
Cyber security is important because your business holds valuable things. It holds customer information. It holds money. It holds your reputation. If your business is not safe, you can lose all these things.
Think of your business as a house. The house has money, jewelry, and important documents. You lock the doors. You close the windows. You have a guard. That is physical security. Cyber security is the same, but for your computers and your online business.
A small shop uses a computer to track sales. The computer has customer names and phone numbers. If the computer is not secure, hackers can steal the customer information.
Your school has a computer lab. The computers have student grades. If the computers are not secure, hackers can change the grades. Cyber security keeps the grades safe.
Your family has a computer at home. It has photos, documents, and maybe bank information. If the computer is not secure, hackers can steal the information. Cyber security keeps it safe.
A Nigerian online store has a website. Customers enter their bank card details. If the website is not secure, fraudsters can steal the card details. Cyber security keeps the customers safe.

Cyber security is keeping your computers, phones, networks, and data safe from bad people. It protects your business from hackers.
Small businesses need cyber security because they have valuable information and money. They are also easier to attack than big companies.
Many small business owners think, "I am too small to be attacked." This is not true. Hackers attack small businesses because they are easier targets. Small businesses often do not have good security.
Imagine a thief walking down a street. There is a big bank on one side. There is a small shop on the other side. The bank has many guards and cameras. The shop has one old lock. Which one will the thief rob? The shop, because it is easier.
A small restaurant uses a computer for orders. The computer has no antivirus. A hacker breaks in and steals customer credit card information. The restaurant loses customers and money.
A small school uses a computer for student records. The computer has a weak password. A hacker breaks in and changes the records. The school loses trust.
A family runs a small business from home. They use a computer for orders. The computer gets a virus. All the order information is lost.
A Nigerian tailor uses a computer for customer measurements. The computer has no backup. A virus deletes all the measurements. The tailor loses many customers.

Small businesses need cyber security because they have valuable information and are easy targets for hackers.
A hacker is a person who tries to break into computers without permission. They want to steal information, cause damage, or make money.
Hackers are real. They are everywhere. They can be far away, in another country. They use the internet to find weak computers. They attack small businesses because they are easy targets.
Imagine a thief walking around your neighbourhood, checking doors to see which ones are unlocked. A hacker does the same thing online. They check computers to see which ones have weak security.
A hacker broke into a small hotel's computer system. He stole guest information. He sold the information to other criminals.
A hacker broke into a small school's website. He changed the exam results. He demanded money to fix it.
A hacker guessed a family's Wi-Fi password. He used their internet to attack other computers.
A Nigerian fraudster sent fake emails to customers of a small online store. He pretended to be the store owner. He stole the customers' bank details.

There are many types of cyber threats. Each type is different. Each type can harm your business.
Knowing the types of threats helps you prepare for them. It helps you protect your business.
Here are the main types of cyber threats:
| Type of Threat | What It Means | Example |
|---|---|---|
| Malware | Bad software that harms your computer | A virus that deletes files |
| Phishing | Fake emails or messages that trick you | An email pretending to be from your bank |
| Ransomware | Bad software that locks your files and asks for money | A message saying "Pay 500,000 naira or lose your files" |
| Data Breach | When private information is stolen | Hackers stealing customer names and passwords |
| Insider Threat | When someone inside the business causes harm | An employee stealing company secrets |
| Denial of Service | When a website is flooded with traffic so it stops working | A website that cannot be accessed |
A small business faces many threats. They face malware, phishing, ransomware, data breaches, insider threats, and denial of service attacks.
Your school faces threats. A student might download malware. A teacher might click on a phishing email. A hacker might steal student data.
Your home faces threats. Your phone might get malware. You might receive a phishing message. Your Wi-Fi might be attacked.
A Nigerian business faces threats. Fraudsters might send phishing emails. Hackers might steal customer data. Employees might leak information.

There are many types of cyber threats: malware, phishing, ransomware, data breaches, insider threats, and denial of service.
Malware is bad software. It is a program that harms your computer. The word "malware" comes from "malicious software." Malicious means wanting to do bad things.
Malware can delete your files. It can slow down your computer. It can steal your information. It can even spy on you. Malware is dangerous for small businesses.
Imagine you have a robot that is supposed to help you clean your shop. But someone changed its program. Now the robot makes a mess instead of cleaning. That is malware. It is software that does bad things instead of good things.
A small shop's computer was infected with malware. The malware deleted all the sales records. The shop owner did not know how much money was made.
A school's computer was infected with malware. The malware deleted all the exam questions. The teachers had to write new questions.
A family's computer was infected with malware. The malware showed pop-up ads all the time. The computer became very slow.
A Nigerian business lost important files because of malware. The malware came from a fake email attachment.

Malware is bad software. It harms your computer by deleting files, stealing information, or spying on you.
Phishing is when a bad person pretends to be someone you trust. They send you a fake email or message. They try to trick you into giving them your password or money.
Phishing is one of the most common ways hackers get into businesses. They trick you into opening the door for them. If you know about phishing, you can avoid it.
Imagine a stranger comes to your shop. He says he is a police officer. He says there is an emergency and you must give him money. But he is not a police officer. He is a thief. Phishing is like that. The hacker pretends to be someone you trust.
A hacker sends an email that looks like it is from a bank. The email says, "Your business account is blocked. Click here to fix it." The link takes you to a fake website that steals your password.
A hacker sends an email that looks like it is from your school. The email says, "Click here to see your exam results." The link steals your password.
A hacker sends a text message that looks like it is from your parents. The message says, "Send me your password." The hacker is tricking you.
A fraudster sends an email that looks like it is from a Nigerian bank. The email says, "Your account has a problem. Send your OTP to fix it." The fraudster steals the money.

Phishing is when a bad person pretends to be someone you trust. They send fake emails or messages to trick you into giving them your password or money.
Ransomware is a type of malware. It locks your files. Then it asks you to pay money to unlock them. The money is called a ransom.
Ransomware is very dangerous. It can lock all your business files. If you do not pay, you might lose everything. Many small businesses have lost important data to ransomware.
Imagine a thief breaks into your shop. He locks all your goods in a room. He says, "Pay me 500,000 naira, or I will throw away the key." That is ransomware. It locks your files and demands money.
A small clinic was attacked by ransomware. The malware locked all patient records. The clinic had to pay to get them back.
A school was attacked by ransomware. The malware locked all student grades. The school had to restore from a backup.
A family was attacked by ransomware. The malware locked all their photos. The family had to pay to get them back.
A Nigerian business was attacked by ransomware. The malware locked all customer data. The business had to pay a large ransom.

Hackers target small businesses because they are easier to attack. Small businesses often do not have good security.
If you know why hackers target small businesses, you can protect yourself. You can make your business a harder target.
Here are reasons why hackers target small businesses:
A hacker attacked a small accounting firm. The firm had client financial data. The hacker stole the data and sold it.
A hacker attacked a small school. The school had student and parent information. The hacker stole the information.
A hacker attacked a family's home business. The business had customer orders. The hacker stole the orders and demanded money.
A fraudster attacked a small Nigerian online store. The store had customer bank details. The fraudster stole the details and took money.

Hackers target small businesses because they have less security, valuable data, less attention, are easy to trick, and can be used to attack bigger companies.
The cost of a cyber attack is the damage it causes. It includes money lost, data lost, and trust lost.
Many small businesses do not recover from a cyber attack. They lose money. They lose customers. They close down. Knowing the cost helps you understand why security is important.
Here are the costs of a cyber attack:
A small business lost 5 million naira to a cyber attack. They also lost customers. They had to close for two weeks.
A small school lost student data to a cyber attack. Parents were angry. Many students left the school.
A family business lost all its customer orders. They could not fulfill orders. They lost money and trust.
A Nigerian business lost 10 million naira to a cyber attack. They also lost customer data. They were fined by NITDA for not protecting the data.

When you use fun examples, learning becomes easier and more enjoyable.
Here are some fun examples:
Imagine you are playing a game. You have a shield that blocks enemy attacks. Cyber security is like that shield for your business.
Your school has a security guard at the gate. He stops bad people from entering. Cyber security is like that guard for your business.
Your family has a mosquito net over the bed. It keeps mosquitoes away. Cyber security is like that net for your business.
In a Nigerian football match, the goalkeeper stops the ball. Cyber security stops hackers.
Fun Cyber Security
+------------------------------------------+
| Video Game: Shield against enemies |
| Football: Goalkeeper stops ball |

+------------------------------------------+
Cyber security is everywhere. It is in video games, football, social media, school, and cooking. It protects your business like armor or a guard.
Cyber security is not just for computers. It is like things in everyday life.
When you understand cyber security in everyday life, you can use the ideas to protect your business.
Here are everyday examples:
You lock your shop at night. You also lock your computer with a password.
You keep your money in a safe. You also keep your data in a secure computer.
You use a mosquito net to keep mosquitoes away. You use antivirus to keep malware away.
A Nigerian family locks their shop at night. They also lock their computer with a strong password.

+------------------------------------------+
Cyber security is like locking your shop, using a safe, checking visitors, keeping secrets, and wearing a seatbelt.
A cyber security checklist is a list of things you should do to keep your business safe.
A checklist helps you remember what to do. It helps you stay safe.
Here is a simple cyber security checklist for your business:
A small shop uses a cyber security checklist. They check it every month. They have not had a cyber attack.
A small school uses a cyber security checklist. They check it every term. They have not had a data breach.
A family business uses a cyber security checklist. They check it every month. They have not had a virus.
A Nigerian online store uses a cyber security checklist. They check it every week. They have not lost any data.

A cyber security checklist includes using strong passwords, 2FA, antivirus, updates, backups, training, locking computers, avoiding strange links, and securing Wi-Fi.
A case study is a real-life example that helps us learn. Let us look at a Nigerian small business.
Case studies help us see how cyber security works in real life.
A Nigerian small business called "Chidi's Electronics" sold phones and laptops. The owner, Chidi, learned about cyber security.
Here is what Chidi did:
One day, a hacker sent a phishing email to Chidi's business. The email said, "Your order has a problem. Click here to fix it."
Chidi's staff member saw the email. She remembered the training. She did not click the link. She reported the email to Chidi.
Chidi was happy. His business was safe because he had prepared.
Chidi learned that cyber security saves businesses.
Chidi shared his success with other small businesses. They all started improving their cyber security.
Your school can use the same approach. Use strong passwords. Train staff. Back up files.
Your family business can use the same approach. Use 2FA. Update software. Back up files.
Nigerian small businesses like Chidi's Electronics use cyber security to stay safe.

Cyber security is keeping your computers, phones, networks, and data safe from bad people.
Small businesses need cyber security because they have valuable information and are easy targets for hackers.
Hackers are people who try to break into computers without permission. They want to steal information, cause damage, or make money.
Types of cyber threats include malware, phishing, ransomware, data breaches, insider threats, and denial of service.
Malware is bad software. It harms your computer by deleting files, stealing information, or spying on you.
Phishing is when a bad person pretends to be someone you trust. They send fake emails or messages to trick you into giving them your password or money.
Ransomware is a type of malware that locks your files and asks for money to unlock them.
Hackers target small businesses because they have less security, valuable data, less attention, are easy to trick, and can be used to attack bigger companies.
The cost includes money lost, data lost, downtime, reputation damage, legal fees, and recovery costs.
Simple cyber security habits include using strong passwords, avoiding strange links, installing antivirus, updating software, backing up files, and training staff.

Welcome to Module One of the Cybersecurity for Small Businesses course!
Have you ever helped your parents run a small shop? Maybe your mother sells food at the market. Maybe your father has a small computer repair business. Maybe your uncle sells clothes online. These are all small businesses.
Small businesses are important. They help families earn money. They help communities grow. They help countries like Nigeria become stronger.
But small businesses also face dangers. There are bad people on the internet. These people are called hackers. Hackers want to steal money. They want to steal information. They want to cause problems.
Cyber security is the practice of keeping your business safe from hackers. It is like locking the door of your shop at night. It is like keeping your money in a safe place. It is like not telling strangers your secrets.
Imagine you have a small shop. You sell beautiful clothes. You keep your money in a box under the counter. You lock the shop at night. You have a guard at the door. That is security for your physical shop.
Now imagine your shop is online. You sell clothes on your website. You keep customer information on your computer. You use the internet to receive payments. You need security for your online shop too. That is cyber security.
In this module, you will learn what cyber security is. You will learn why it matters for small businesses. You will learn about the dangers that small businesses face. You will learn simple things you can do to stay safe.
You do not need to be a computer expert. You just need to be curious and ready to learn. By the end of this module, you will understand how to protect a small business from cyber threats.
Let us begin this exciting journey together!
After completing this module, you will be able to:
Once upon a time, in the busy city of Onitsha, Nigeria, there lived a woman named Mama Ngozi. Mama Ngozi had a small fashion shop. She sold beautiful clothes, shoes, and bags.
Mama Ngozi's shop was very popular. Many people came to buy from her. She had many customers. She made good money.
One day, Mama Ngozi decided to start selling online. She created a website. She posted pictures of her clothes. She added a payment option so customers could pay with their bank cards.
At first, everything was good. Customers from all over Nigeria bought from her website. Mama Ngozi was very happy.
Then one day, something terrible happened. Mama Ngozi received an email. The email said, "Your website has a problem. Click here to fix it."
Mama Ngozi was worried. She clicked on the link. The link took her to a website that looked like her website. It asked for her username and password. She entered them.
The next day, Mama Ngozi tried to log in to her website. She could not. Her password did not work. She tried again. It still did not work.
Then she received another email. It said, "We have taken over your website. Pay us 500,000 naira, or we will delete everything."
Mama Ngozi started to cry. Her website was gone. All her customer information was gone. All her product photos were gone. She had lost everything.
Her son, Emeka, came to visit. He saw that his mother was crying.
"Mama," he said, "what is wrong?"
Mama Ngozi told him what happened. Emeka listened carefully.
"Mama," Emeka said, "you have been a victim of a phishing attack. The email was fake. The website was fake. They tricked you into giving them your password."
Mama Ngozi was confused. "What is phishing?" she asked.
Emeka explained. "Phishing is when bad people pretend to be someone you trust. They send you a fake email. They try to trick you into giving them your password or money."
Mama Ngozi understood. She had been tricked. She had not been careful.
Emeka helped his mother. They called a cyber security expert. The expert helped them get the website back. They changed all the passwords. They trained Mama Ngozi and her workers about cyber security.
Mama Ngozi learned a very important lesson. Cyber security is important for small businesses. If you are not careful, you can lose everything.
From that day on, Mama Ngozi was very careful. She never clicked on strange links. She used strong passwords. She trained her workers. Her business grew and grew.
And that is exactly what you will learn in this module.
Cyber security is the practice of keeping computers, phones, networks, and data safe from bad people. It is all the things you do to protect your business from hackers.
Cyber security is important because your business holds valuable things. It holds customer information. It holds money. It holds your reputation. If your business is not safe, you can lose all these things.
Think of your business as a house. The house has money, jewelry, and important documents. You lock the doors. You close the windows. You have a guard. That is physical security. Cyber security is the same, but for your computers and your online business.
A small shop uses a computer to track sales. The computer has customer names and phone numbers. If the computer is not secure, hackers can steal the customer information.
Your school has a computer lab. The computers have student grades. If the computers are not secure, hackers can change the grades. Cyber security keeps the grades safe.
Your family has a computer at home. It has photos, documents, and maybe bank information. If the computer is not secure, hackers can steal the information. Cyber security keeps it safe.
A Nigerian online store has a website. Customers enter their bank card details. If the website is not secure, fraudsters can steal the card details. Cyber security keeps the customers safe.

Cyber security is keeping your computers, phones, networks, and data safe from bad people. It protects your business from hackers.
Small businesses need cyber security because they have valuable information and money. They are also easier to attack than big companies.
Many small business owners think, "I am too small to be attacked." This is not true. Hackers attack small businesses because they are easier targets. Small businesses often do not have good security.
Imagine a thief walking down a street. There is a big bank on one side. There is a small shop on the other side. The bank has many guards and cameras. The shop has one old lock. Which one will the thief rob? The shop, because it is easier.
A small restaurant uses a computer for orders. The computer has no antivirus. A hacker breaks in and steals customer credit card information. The restaurant loses customers and money.
A small school uses a computer for student records. The computer has a weak password. A hacker breaks in and changes the records. The school loses trust.
A family runs a small business from home. They use a computer for orders. The computer gets a virus. All the order information is lost.
A Nigerian tailor uses a computer for customer measurements. The computer has no backup. A virus deletes all the measurements. The tailor loses many customers.

Small businesses need cyber security because they have valuable information and are easy targets for hackers.
A hacker is a person who tries to break into computers without permission. They want to steal information, cause damage, or make money.
Hackers are real. They are everywhere. They can be far away, in another country. They use the internet to find weak computers. They attack small businesses because they are easy targets.
Imagine a thief walking around your neighbourhood, checking doors to see which ones are unlocked. A hacker does the same thing online. They check computers to see which ones have weak security.
A hacker broke into a small hotel's computer system. He stole guest information. He sold the information to other criminals.
A hacker broke into a small school's website. He changed the exam results. He demanded money to fix it.
A hacker guessed a family's Wi-Fi password. He used their internet to attack other computers.
A Nigerian fraudster sent fake emails to customers of a small online store. He pretended to be the store owner. He stole the customers' bank details.

There are many types of cyber threats. Each type is different. Each type can harm your business.
Knowing the types of threats helps you prepare for them. It helps you protect your business.
Here are the main types of cyber threats:
| Type of Threat | What It Means | Example |
|---|---|---|
| Malware | Bad software that harms your computer | A virus that deletes files |
| Phishing | Fake emails or messages that trick you | An email pretending to be from your bank |
| Ransomware | Bad software that locks your files and asks for money | A message saying "Pay 500,000 naira or lose your files" |
| Data Breach | When private information is stolen | Hackers stealing customer names and passwords |
| Insider Threat | When someone inside the business causes harm | An employee stealing company secrets |
| Denial of Service | When a website is flooded with traffic so it stops working | A website that cannot be accessed |
A small business faces many threats. They face malware, phishing, ransomware, data breaches, insider threats, and denial of service attacks.
Your school faces threats. A student might download malware. A teacher might click on a phishing email. A hacker might steal student data.
Your home faces threats. Your phone might get malware. You might receive a phishing message. Your Wi-Fi might be attacked.

There are many types of cyber threats: malware, phishing, ransomware, data breaches, insider threats, and denial of service.
Malware is bad software. It is a program that harms your computer. The word "malware" comes from "malicious software." Malicious means wanting to do bad things.
Malware can delete your files. It can slow down your computer. It can steal your information. It can even spy on you. Malware is dangerous for small businesses.
Imagine you have a robot that is supposed to help you clean your shop. But someone changed its program. Now the robot makes a mess instead of cleaning. That is malware. It is software that does bad things instead of good things.
A small shop's computer was infected with malware. The malware deleted all the sales records. The shop owner did not know how much money was made.
A school's computer was infected with malware. The malware deleted all the exam questions. The teachers had to write new questions.
A family's computer was infected with malware. The malware showed pop-up ads all the time. The computer became very slow.
A Nigerian business lost important files because of malware. The malware came from a fake email attachment.

Malware is bad software. It harms your computer by deleting files, stealing information, or spying on you.
Phishing is when a bad person pretends to be someone you trust. They send you a fake email or message. They try to trick you into giving them your password or money.
Phishing is one of the most common ways hackers get into businesses. They trick you into opening the door for them. If you know about phishing, you can avoid it.
Imagine a stranger comes to your shop. He says he is a police officer. He says there is an emergency and you must give him money. But he is not a police officer. He is a thief. Phishing is like that. The hacker pretends to be someone you trust.
A hacker sends an email that looks like it is from a bank. The email says, "Your business account is blocked. Click here to fix it." The link takes you to a fake website that steals your password.
A hacker sends an email that looks like it is from your school. The email says, "Click here to see your exam results." The link steals your password.
A hacker sends a text message that looks like it is from your parents. The message says, "Send me your password." The hacker is tricking you.
A fraudster sends an email that looks like it is from a Nigerian bank. The email says, "Your account has a problem. Send your OTP to fix it." The fraudster steals the money.

Phishing is when a bad person pretends to be someone you trust. They send fake emails or messages to trick you into giving them your password or money.
Ransomware is a type of malware. It locks your files. Then it asks you to pay money to unlock them. The money is called a ransom.
Ransomware is very dangerous. It can lock all your business files. If you do not pay, you might lose everything. Many small businesses have lost important data to ransomware.
Imagine a thief breaks into your shop. He locks all your goods in a room. He says, "Pay me 500,000 naira, or I will throw away the key." That is ransomware. It locks your files and demands money.
A small clinic was attacked by ransomware. The malware locked all patient records. The clinic had to pay to get them back.
A school was attacked by ransomware. The malware locked all student grades. The school had to restore from a backup.
A family was attacked by ransomware. The malware locked all their photos. The family had to pay to get them back.
A Nigerian business was attacked by ransomware. The malware locked all customer data. The business had to pay a large ransom.

Hackers target small businesses because they are easier to attack. Small businesses often do not have good security.
If you know why hackers target small businesses, you can protect yourself. You can make your business a harder target.
Here are reasons why hackers target small businesses:
A hacker attacked a small accounting firm. The firm had client financial data. The hacker stole the data and sold it.
A hacker attacked a small school. The school had student and parent information. The hacker stole the information.
A hacker attacked a family's home business. The business had customer orders. The hacker stole the orders and demanded money.
A fraudster attacked a small Nigerian online store. The store had customer bank details. The fraudster stole the details and took money.

Hackers target small businesses because they have less security, valuable data, less attention, are easy to trick, and can be used to attack bigger companies.
The cost of a cyber attack is the damage it causes. It includes money lost, data lost, and trust lost.
Many small businesses do not recover from a cyber attack. They lose money. They lose customers. They close down. Knowing the cost helps you understand why security is important.
Here are the costs of a cyber attack:
A small business lost 5 million naira to a cyber attack. They also lost customers. They had to close for two weeks.
A small school lost student data to a cyber attack. Parents were angry. Many students left the school.
A family business lost all its customer orders. They could not fulfill orders. They lost money and trust.
A Nigerian business lost 10 million naira to a cyber attack. They also lost customer data. They were fined by NITDA for not protecting the data.

Cyber security can be explained using fun examples that children understand.
When you use fun examples, learning becomes easier and more enjoyable.
Here are some fun examples:
Imagine you are playing a game. You have a shield that blocks enemy attacks. Cyber security is like that shield for your business.
Your school has a security guard at the gate. He stops bad people from entering. Cyber security is like that guard for your business.
Your family has a mosquito net over the bed. It keeps mosquitoes away. Cyber security is like that net for your business.
In a Nigerian football match, the goalkeeper stops the ball. Cyber security stops hackers.
Fun Cyber Security
+------------------------------------------+
| Video Game: Shield against enemies |
| Football: Goalkeeper stops ball |

| School: Lock your locker |
| Cooking: Cover keeps flies away |
+------------------------------------------+
Cyber security is everywhere. It is in video games, football, social media, school, and cooking. It protects your business like armor or a guard.
Cyber security is not just for computers. It is like things in everyday life.
When you understand cyber security in everyday life, you can use the ideas to protect your business.
Here are everyday examples:
You lock your shop at night. You also lock your computer with a password.
You keep your money in a safe. You also keep your data in a secure computer.
You use a mosquito net to keep mosquitoes away. You use antivirus to keep malware away.
A Nigerian family locks their shop at night. They also lock their computer with a strong password.
Everyday Cyber Security
+------------------------------------------+
| Lock Shop: Keep thieves out |
| Use Safe: Keep money safe |
| Check Visitors: Antivirus checks |
| Keep Secrets: Do not share passwords |
| Seatbelt: Stay safe |
+------------------------------------------+
Cyber security is like locking your shop, using a safe, checking visitors, keeping secrets, and wearing a seatbelt.
A cyber security checklist is a list of things you should do to keep your business safe.
A checklist helps you remember what to do. It helps you stay safe.
Here is a simple cyber security checklist for your business:
A small shop uses a cyber security checklist. They check it every month. They have not had a cyber attack.
A small school uses a cyber security checklist. They check it every term. They have not had a data breach.
A family business uses a cyber security checklist. They check it every month. They have not had a virus.
A Nigerian online store uses a cyber security checklist. They check it every week. They have not lost any data.

A cyber security checklist includes using strong passwords, 2FA, antivirus, updates, backups, training, locking computers, avoiding strange links, and securing Wi-Fi.
A case study is a real-life example that helps us learn. Let us look at a Nigerian small business.
Case studies help us see how cyber security works in real life.
A Nigerian small business called "Chidi's Electronics" sold phones and laptops. The owner, Chidi, learned about cyber security.
Here is what Chidi did:
One day, a hacker sent a phishing email to Chidi's business. The email said, "Your order has a problem. Click here to fix it."
Chidi's staff member saw the email. She remembered the training. She did not click the link. She reported the email to Chidi.
Chidi was happy. His business was safe because he had prepared.
Chidi learned that cyber security saves businesses.
Chidi shared his success with other small businesses. They all started improving their cyber security.
Your school can use the same approach. Use strong passwords. Train staff. Back up files.
Your family business can use the same approach. Use 2FA. Update software. Back up files.
Nigerian small businesses like Chidi's Electronics use cyber security to stay safe.

Small businesses need cyber security because they have valuable information and are easy targets for hackers.
A hacker is a person who tries to break into computers without permission. They want to steal information, cause damage, or make money.
There are many types of cyber threats: malware, phishing, ransomware, data breaches, insider threats, and denial of service.
Malware is bad software. It harms your computer by deleting files, stealing information, or spying on you.
Phishing is when a bad person pretends to be someone you trust. They send fake emails or messages to trick you into giving them your password or money.
Ransomware is a type of malware that locks your files and asks for money to unlock them. It is very dangerous.
Hackers target small businesses because they have less security, valuable data, less attention, are easy to trick, and can be used to attack bigger companies.
The cost of a cyber attack includes money lost, data lost, downtime, reputation damage, legal fees, and recovery costs.
Simple cyber security habits include using strong passwords, avoiding strange links, installing antivirus, updating software, backing up files, and training staff.
Nigerian online stores, banks, schools, businesses, and government agencies all use cyber security to stay safe.
Cyber security is everywhere. It is in video games, football, social media, school, and cooking. It protects your business like armor or a guard.
Cyber security is like locking your shop, using a safe, checking visitors, keeping secrets, and wearing a seatbelt.
A cyber security checklist includes using strong passwords, 2FA, antivirus, updates, backups, training, locking computers, avoiding strange links, and securing Wi-Fi.
