Section 1.1 — Comparing AI Types and Techniques Used in Cybersecurity

Hi, it's Furkan. I'm a security professional prepping for the CompTIA SecAI+ (CY0-001) cert, and I couldn't find study material that actually clicked for me, so I built my own and structured it around the exam blueprint. This is me sharing it back. Each post maps to one objective, and I've leaned hard on real-world scenarios because that's what made it stick for me. If it helps you pass too, even better. CompTIA SecAI+ CY0-001 | Domain 1.0: Basic AI Concepts Related to Cybersecurity "Compare and contrast various AI types and techniques used in cybersecurity." 🧠 What's in This Section? This one breaks down into three big building blocks: AI Types — which kind of AI does what, and where it shows up in security Model Training Techniques — how a model actually gets trained and tuned Prompt Engineering — how to ask an AI the right question Ready? Let's get into it. 🔷 PART 1: Types of AI AI isn't one single thing. Different problems call for different AI approaches. Think of a carpenter's toolbox: there's a hammer, a screwdriver, a saw. They all do different jobs, but they're all "tools." AI types work the same way. 1. Generative AI What it does: Creates new content. Text, images, audio, code; whatever you ask for. How it works: Models trained on huge amounts of data use the patterns they've learned to produce outputs that never existed before. They don't memorize, they learn patterns and then build new things out of them. In security: Defense side: Building security awareness training by simulating phishing emails, auto-generating incident response playbooks, drafting security reports. Offense side: Attackers use generative AI to spin up convincing phishing emails, deepfake audio, or malicious code. 🍕 Real-World Example: A security team wants to test their employees, so they use generative AI to write phishing emails that nail the CEO's writing style. "Hey, I need you to push through an urgent payment...", the email is so realistic that 40% of staff click. That right the
