Introduction to Cybersecurity. I’m going to explain this like your favorite teacher who’s excited about the topic and wants you to really get it—not just memorize it. We’ll use lots of everyday examples, real-life...

Core Security Principles and Models. Think of this as the “blueprint” chapter—where we learn the foundational rules and philosophies that smart systems follow to stay secure. I’ll explain everything in detail, like we’re sitting...
