Welcome to your cyber security journey! This book, 'Cyber Security Roadmap for Beginners 2025: Your Essential Guide to Foundational Skills,' is designed to equip you with the fundamental knowledge and practical skills needed to navigate the ever-evolving digital landscape. We understand that the world of cyber security can seem daunting, but by breaking it down into manageable steps, you'll be well on your way to becoming cyber-aware and capable.
In the following chapters, we'll systematically build your understanding, starting with the core concepts and progressing to more hands-on applications. Here's a glimpse of what this book will cover:
- Understanding the Threat Landscape: We'll explore the common types of cyber threats you're likely to encounter in 2025, from malware and phishing to social engineering and advanced persistent threats (APTs). You'll learn about the motivations behind these attacks and how they impact individuals and organizations.
- Essential Cyber Security Principles: This section delves into the foundational pillars of cyber security, including confidentiality, integrity, and availability (the CIA triad). We'll also introduce concepts like least privilege, defense in depth, and the importance of regular security awareness training.
