    CompTIA SecAI+ Domain 2.5: Blue Team Defense & AI Guardrails

    Port 443 is always open, traffic is encrypted, and the attack looks like valid English. You cannot fix AI security with a traditional firewall. In this episode of the SecAI+ Course, we enter Domain 3: Blue Team Operations. We are building the "AI Shield"—the new defense stack required to protect Large Language Models from injection, sponge attacks, and data leakage. 🔥 Topics Covered: * Input Validation: Prompt Firewalls & Sanitization (NVIDIA NeMo, LangChain) * Rate Limiting: Defending against Sponge Attacks * Output Filtering: Preventing Data Leakage & Insecure Code * C2PA: The new standard for Content Provenance & Authenticity * Modern SIEM/SOAR: Using UEBA to detect anomalies * Federated Learning: Training models without moving private data 🎓 Pass the Exam: ​📚 Resources & Support ​🎓 FREE Interactive Learning Tools Don't just watch—practice.

    CompTIA SecAi+ Domain 2.4: Model Theft, Model DOS, Excessive Agency, Insecure Output Handling

    Master Prompt Injection & Jailbreaking for the CompTIA SecAI+ (Domain 2). In this lesson, we break down the most dangerous (and fun) part of AI Security: Input Attacks. Your firewall stops traffic. It does not stop words. 🛡️🚫 OWASP LLM 1, 3, 5, 10 are covered previous video link here: https://youtu.be/d4zx2amlnvU In Part 2 of our Domain 2 Deep Dive, we cover the "Context Mixing" flaw that makes all LLMs vulnerable. We explain how attackers use Prompt Injection to turn helpful chatbots into "Confused Deputies" that attack their own users. We break down the critical difference between standard Jailbreaking (Roleplaying/DAN) and the mathematical magic of Universal Adversarial Triggers (UATs). But the scariest attack isn't when you talk to the AI—it's when the AI reads a file you didn't check. We demonstrate Indirect Prompt Injection and how a simple resume PDF can hack your recruiting bot. 🎓 What You Will Learn: 🧠 Context Mixing: Why LLMs fundamentally cannot distinguish between "Safe Data" and "Malicious Instructions." 🔓 Jailbreaking Types: The difference between "DAN" (Roleplaying) and "Logical Bypasses" (Translation exploits). 🔢 Universal Adversarial Triggers (UATs): The "magic words" (nonsense strings) that break models mathematically using Gradient Ascent. 🕵️‍♂️ Indirect Prompt Injection: The invisible attack inside PDFs and websites (Zero-Click exploits). 📦 Token Smuggling: Using Payload Splitting to sneak malware concepts past the WAF. 💸 Wallet Exhaustion: How Recursive Loops drain your bank account (Denial of Wallet). ​📚 Resources & Support ​🎓 FREE Interactive Learning Tools Don't just watch—practice.

    CompTIA SecAI+ Domain 2.3: Model Inversion, Inference & Poisoning

    I don't need to break into your server to steal your AI. I just need to ask it the right questions. In Part 3 of our Domain 2 Deep Dive, we leave the "Prompt Injection" attacks behind and enter the world of Privacy Attacks and Model Theft. We explain how attackers can use Model Inversion to reconstruct private training data (like faces) just by analyzing confidence scores. We break down the difference between Membership Inference (knowing if you were a patient) and Attribute Inference (knowing what disease you have). Finally, we cover Model Extraction (cloning GPT-4 for cheap) and the silent killer known as Data Poisoning—where attackers install "Backdoors" into the model before it's even trained. 🎓 In this video, you will learn: Model Inversion: Reconstructing training data (faces/PII) from vector outputs. Membership Inference vs. Attribute Inference: The subtle difference between exposing a user and exposing their secrets. Model Stealing (Distillation): How "Student" models cheat off "Teacher" models to steal IP. Adversarial Reprogramming: Hijacking a medical AI to mine cryptocurrency. Data Poisoning: Split-View attacks and installing "Backdoors" (The Sticky Note hack). Sponge Examples: Attacks designed to burn energy and overheat hardware. ⏱️ Timestamps: 00:00 Intro: The "Heist" Concept 01:05 Model Inversion (Reconstructing Faces) 01:55 Membership Inference vs. Attribute Inference 02:45 Model Stealing (Distillation Attacks) 03:15 Adversarial Reprogramming (Hijacking Compute) 03:40 Data Poisoning & Split-View Attacks 04:30 How to Stop It (Teaser) 04:45 Support the Channel (Buy Me a Coffee) 05:05 Homework: Sponge Examples ​📚 Resources & Support ​🎓 FREE Interactive Learning Tools Don't just watch—practice.
