Cyber Security for Beginners: Your Ultimate Guide

Cyber security can seem daunting with the vast amount of information available. As a beginner, it can be challenging to know where to start. In this guide, we’ll cover the three most important areas of cyber security. Stick around to the end for some free resources to help you dive deeper.

What is Cyber Security?

A simple way to describe cyber security is protecting people and their computers from bad actors and their malicious activities. Let’s break this down into three core areas:

1. Digital Security

  • Passwords, Passphrases, and Passkeys: These are your first line of defense against unauthorized access.
  • Operating Systems: Keeping your OS up-to-date and secure is crucial.

2. Physical Security

  • Badges and ID Cards: Used to control access to physical locations, ensuring that only authorized personnel can enter sensitive areas.

3. Social Security

  • User Awareness: Educating users about safe online behaviors and recognizing potential threats, both at work and home.

Types of Cyber Threats

Cyber threats come in many forms, from curious teenagers to sophisticated state-sponsored actors. Here’s a quick rundown:

  • Curious Teenagers: Often driven by curiosity, they might deface websites or try to access systems for fun.
  • Scammers: They use phishing emails, fake messages, and calls to steal information or money.
  • Unethical Hackers: More skilled than scammers, they use malware, ransomware, and other tools to exploit systems for financial gain.
  • State-Sponsored Actors: These highly skilled attackers often work for governments and can develop custom tools to infiltrate specific targets.

Fundamental Skills in Cyber Security

Red Team vs. Blue Team

  • Red Team: Simulates criminal activities to test systems’ defenses.
  • Blue Team: Focuses on defending and securing systems against attacks.

Key Areas to Learn

  • Operating Systems (e.g., Linux): Understanding OS fundamentals is crucial.
  • Networking: Learn how data travels across networks, including frames, packets, and various protocols.
  • Encryption and Programming: While you don’t need to be a coding expert, familiarity with programming languages like Python can be beneficial.
