What is Cyber Security and Why is it Important?
Cyber security refers to the practice of protecting digital data and information, networks, and computers from attacks, damage, or unauthorised access. In simple words, it’s basically the defence system of the internet to prevent hackers from stealing personal information, disrupting business, or damaging government infrastructure.
The digital landscape continuously evolves, and it makes us all more connected through online banking, remote work, smart devices, and cloud platforms, hence the risk of cyber threats.
The 4 Most Common Types of Cyber Security
Cyber security is a broad field with several areas of specialisation. Understanding the five key types helps build a strong foundation for individuals and businesses:
Application Security - Secures software and apps during development and after deployment.
Network Security - Focuses on protecting internal networks (LANs, WANs) from unauthorised access or misuse.
Cloud Security - Protects systems, data, and infrastructure hosted on cloud platforms like AWS, Azure, Google Cloud.
Endpoint Security - Secures individual devices like laptops, desktops, phones, etc., that connect to networks. This includes endpoint protection tools such as antivirus software, which helps detect and block malware, ransomware, and other malicious threats.
Have You Heard of the CIA Triad?
The CIA Triad is a core concept in cyber security, standing for Confidentiality, Integrity, and Availability. These three principles form the foundation of secure systems:
Confidentiality - Ensures information is only accessible to authorised users.
Integrity - Keeps data accurate and unaltered.
Availability - Ensures systems and data are accessible when needed.
Mastering the CIA Triad is essential for anyone working in the cyber field — and it's a key concept you’ll learn in your training at Applied Education.
Common Types of Cyber Attacks You Need to Know
Cyber attacks are becoming increasingly sophisticated, targeting critical infrastructure of individuals, businesses, and organisations alike. Understanding the different types of attacks is the first step in protecting your data and devices.
Malware & Ransomware - Malicious software that can damage systems or lock your files for ransom.
Social Engineering and Phishing - Designed to steal confidential information through fake emails, texts, or phone calls.
Man-in-the-Middle (MitM) Attack - MitM happens when a hacker secretly intercepts and possibly alters the communication between two people, devices, or systems — without either party knowing.
Imagine you're sending a private message to a friend, but someone is sitting in between, reading or even changing that message before it gets to your friend.
Denial-of-Service Attack - Aims to shut down computer systems, network, or website by overwhelming it with excessive traffic or requests. This overload prevents real users from accessing the service — essentially making it crash or freeze.
Zero-day Exploit - A Zero-Day Exploit is a cyber attack that takes advantage of a vulnerability in software or hardware that the developers don’t know about yet.
For example, a hacker finds a hidden flaw in your phone’s operating system and uses it to install spyware — before Apple or Google even knows the flaw exists.
Password Attack - These involve hackers gaining access by guessing or stealing your password.
Internet of Things Attack - The Internet of Things (IoT) refers to everyday devices connected to the internet, like:
- Smart TVs
- Smart thermostats
- Wearable fitness trackers
- Home security systems
- Industrial sensors
- Injection Attack
In these security threats, hackers "inject" malicious code into a vulnerable system (usually a form or search bar on a website). If the system doesn’t properly filter input, the hacker can:
- Access or steal data
- Delete or modify databases
- Gain full control over the system

Advantages and Disadvantages of Cyber Security
Cyber security offers many benefits, but like any field, it has its challenges. Digital information security is the practice of protecting data from security breach, ensuring the confidentiality, integrity, and availability of sensitive information.
Advantages:
- Protects sensitive information and systems
- Prevents financial loss
- Prevent unauthorised access and data breaches
- Builds trust with customers and users
- Opens up high-demand career opportunities
Disadvantages:
- Can require ongoing investment in tools and training
- Systems may become complex to manage
- New threats constantly emerge, requiring regular updates
Despite the challenges, the advantages of strong cyber security operations far outweigh the risks — and qualified professionals are key to success.
