The world today is more connected than ever before. With the Internet of Things (IoT), cloud computing, and the increasing use of smartphones, the need for Cyber Security has never been more urgent. Cyber Security is the practice of protecting devices, networks, and sensitive information from unauthorized access, theft, and damage.
For beginners who are interested in pursuing a career in cybersecurity, it can be overwhelming to know where to start. In this article, we will explore the basics of cybersecurity and the types of cybersecurity that beginners should focus on.
What is Cyber Security?
Cyber security refers to the protection of computer systems, networks, and devices from theft, damage, or unauthorized access. This involves implementing various measures, such as firewalls, encryption, and access controls, to prevent cyber attacks.
Cyber attacks can take many forms, including viruses and malware, phishing attacks, ransomware attacks, and social engineering attacks. These attacks can be carried out through various means, such as email, instant messaging, and social media.
Why is Cyber Security Important?
Cybersecurity is important for several reasons:
Protecting Personal and Professional Information
Cyber security helps to protect personal and professional information from theft, damage, or unauthorized access. This includes sensitive data such as credit card numbers, social security numbers, and intellectual property.
Preventing Financial Loss
Cyber attacks can cause significant financial losses for individuals and organizations. For example, a ransomware attack can result in the loss of access to critical data and require payment of a ransom to regain access.
Maintaining Business Continuity
Cyber attacks can disrupt business operations, leading to lost productivity and revenue. By implementing strong cyber security measures, organizations can help to ensure business continuity even in the event of a cyber attack.
Complying with Regulations
Many industries are subject to regulations related to data protection, such as HIPAA for healthcare organizations or PCI DSS for payment card processors. By implementing strong cyber security measures, organizations can ensure compliance with these regulations.
What Should You Learn Before Cyber Security?
Before diving into the world of cybersecurity, it is crucial to have a strong foundation in IT fundamentals. IT fundamentals encompass various categories and areas, such as hardware, software, networking, and applications. Hardware includes the physical components of computers and computing devices, while software refers to the suite of tools and data that tell the computer how to work, including operating systems, software, and applications.
You must have an idea about IT fundamentals terms before getting into Cyber security:
IT Fundamentals is a term used to describe the basic concepts and principles of information technology. This includes understanding the hardware and software components of computer systems, networking, operating systems, databases, and security. Let’s see the key concepts of IT Fundamentals and why it is essential for anyone who wants to pursue a career in cyber technology.
Key Concepts of IT Fundamentals
- Hardware and Software Components At the core of any computer system are the hardware and software components. The hardware includes the physical components of the computer, such as the central processing unit (CPU), memory, hard disk drive, and input/output devices. The software includes the operating system, applications, and programming languages.
- Networking Networking is the process of connecting two or more devices together to share resources and data. The internet is the most prominent example of networking, but local networks can also be used in a variety of applications. Understanding the basics of networking, including IP addressing, routing, and protocols, is critical for anyone who wants to work in network administration, cybersecurity, or cloud computing.
- Operating Systems An operating system (OS) is the software that controls the hardware components of a computer system. It manages the memory, processing power, and input/output devices. Examples of operating systems include Windows, macOS, and Linux.
- Databases A database is a collection of organized data that can be accessed and manipulated by computer systems. Examples of databases include MySQL, Oracle, and Microsoft SQL Server.
- Security Security is a critical component of IT Fundamentals. Understanding how to secure computer systems and data is essential for anyone who wants to work in cybersecurity.
Types of Cyber Security Protections
There are different types of cybersecurity protections that beginners should be familiar with. These include:
1. Network Security:
Network security involves securing the network infrastructure and preventing unauthorized access to networks. Beginners should learn the basics of firewalls, intrusion detection systems, and encryption protocols to safeguard networks from external attacks.
2. Application Security:
Application security focuses on securing software applications from external threats. Beginners should learn the basics of secure coding practices, vulnerability scanning, and penetration testing to identify and address potential security risks in applications.
3. Information Security:
Information security involves protecting sensitive data from unauthorized access, theft, and damage. Beginners should learn the basics of data encryption, access control mechanisms, and data backup and recovery strategies to safeguard sensitive information.
4. Cloud Security:
Cloud security involves securing data and applications that are hosted in the cloud. Beginners should learn the basics of cloud security best practices, such as secure configuration, identity and access management, and data protection to ensure the confidentiality, integrity, and availability of data in the cloud.

Common Cyber Security Risks to Look Out For
In addition to understanding the types of cybersecurity protections, beginners should also be aware of common cybersecurity risks. These include:
- Malware: Malware is any software designed to harm a computer system, steal data, or gain unauthorized access to a network.
- Phishing: Phishing is a type of social engineering attack where attackers use emails or messages to trick users into revealing sensitive information or downloading malware.
- Denial of Service (DoS) Attacks: DoS attacks are aimed at making a network or website unavailable by overwhelming it with traffic.
- Insider Threats: Insider threats are caused by employees or contractors who intentionally or unintentionally cause harm to the organization’s information security.
- Advanced Persistent Threats (APTs): APTs are targeted attacks on specific organizations or individuals that are carried out over a long period of time.
Basics of Network and Device Security
Network and device security are essential components of cybersecurity. Beginners should learn the following basics:
- Keeping software and operating systems up to date with the latest security patches.
