The Beginner’s Guide to Understanding What CyberSecurity Is

As technology continues to evolve, the threats to our online security also increase, making it more important than ever to understand cybersecurity. In this beginner’s guide, we will provide an overview of what cybersecurity is, why it is important, and how you can get started in this field.

Introduction to Cyber Security

Cybersecurity refers to the practice of protecting computer systems, networks, and digital information from unauthorized access, theft, and damage. In today’s digital age, cybersecurity has become a critical component of our daily lives, as we rely on technology to store and transmit sensitive information like bank account details, social security numbers, and medical records.

What is Cyber Security and Why is it Important?

Cybersecurity is the practice of protecting digital systems and information from unauthorized access, theft, and damage. It is important because cyber threats can cause serious harm to individuals, businesses, and governments. Cybercriminals can steal sensitive information, cause financial losses, and disrupt critical infrastructure, among other things.

To combat these threats, cybersecurity professionals use a range of techniques and tools, including firewalls, antivirus software, encryption, and intrusion detection systems. They also monitor networks and systems for suspicious activity and respond quickly to security incidents.

Cyber Security in Nigeria – An Overview

In Nigeria, the need for cybersecurity is growing rapidly, as more people access the internet and use digital platforms for communication, commerce, and entertainment. The Nigerian government has recognized the importance of cyber security and has taken steps to improve the country’s cybersecurity posture.

The National Information Technology Development Agency (NITDA) is responsible for implementing cybersecurity policies and programs in Nigeria. The agency has developed a National Cybersecurity Policy and Strategy, which outlines the government’s approach to cybersecurity and sets out a framework for protecting critical infrastructure, promoting cybersecurity awareness, and fostering international collaboration.

Understanding the Cyber Security Threat Landscape

The cybersecurity threat landscape is constantly evolving, as cybercriminals develop new tactics and techniques to exploit vulnerabilities in digital systems and networks. Some of the most common cybersecurity threats include:

  • Phishing attacks: These are attempts to trick users into providing sensitive information, such as login credentials or credit card details, by posing as a trustworthy entity.
  • Malware: This is malicious software that is designed to damage, disrupt, or gain unauthorized access to computer systems and networks.
  • Ransomware: This is a type of malware that encrypts a user’s files and demands payment in exchange for the decryption key.
  • Social engineering: This is the use of psychological manipulation to trick users into divulging sensitive information or performing actions that are harmful to themselves or their organizations.

Basic Cyber Security Concepts for Beginners

If you’re new to cybersecurity, there are some basic concepts that you should be familiar with. These include:

  • Authentication: This is the process of verifying a user’s identity to ensure that they are authorized to access a system or network.
  • Encryption: This is the process of converting plain text into ciphertext to protect sensitive information from unauthorized access.
  • Firewall: This is a network security system that monitors and controls incoming and outgoing network traffic to prevent unauthorized access.
  • Intrusion detection system (IDS): This is a software application that monitors network traffic for signs of malicious activity and alerts security personnel when such activity is detected.
