Whether you are a beginner or an experienced professional, these actionable insights will enhance your knowledge, familiarise you with a few technical skills needed in cyber security, and prepare you for today’s cyber landscape challenges.
1. Understanding the Basics of Cyber Security
Cyber Security is all about protecting our digital world—our devices, systems, and information—from threats that can cause harm. Let’s explore what cyber security means, why it matters, and the essential concepts you need to know to stay safe online.
1.1. Definition and Importance
Cyber Security refers to the practices, tools, and techniques to safeguard systems, networks, and data from unauthorised access, damage, or theft. It is vital because, in today’s digital age, we rely heavily on technology for everything—from banking and shopping to communication and work.
1.2. Core Cyber Security Concepts
The foundation of Cyber Security lies in understanding the CIA Triad, which stands for:
- Confidentiality: Ensuring that information is only accessible to those authorised to view it. For example, your bank account details should only be visible to you and your bank, not to hackers.
- Integrity: Ensuring that data is accurate and hasn’t been tampered with. For instance, sending a message should reach the recipient exactly as you wrote it, without any alterations.
- Availability: Ensuring that systems and data are accessible when needed. Imagine trying to access your online bank account, but the system is down—a breach of availability.
Common Cyber Threats
Here are some of the most frequent types of cyber threats you witness, for which the technical skills needed for cybersecurity should be sharp.
- Phishing: This involves fake emails or messages that trick people into sharing sensitive information, like passwords or credit card details.
- Ransomware: This malicious software locks your files or systems and demands a payment (ransom) to unlock them.
- DDoS Attacks (Distributed Denial of Service) flood a system with traffic to overwhelm it, causing disruptions in everyday operations.
