About this course

As more applications integrate Large Language Models (LLMs), securing them against manipulation is no longer optional. An insecure prompt can lead to data leaks, harmful content, and unreliable system behavior, undermining user trust and creating significant risks. This course provides a foundational understanding of prompt security. You will learn to identify common vulnerabilities and implement effective defensive measures, enabling you to build safer and more robust AI-powered features. You'll gain the confidence to write more secure prompts and architect more resilient systems. What you'll learn: - Understand the core concepts of prompt hacking, including prompt injection and jailbreaking. - Learn defensive prompting techniques to create robust system instructions for AI models. - Practice identifying vulnerabilities in prompts and application designs through written exercises. - Explore methods for sanitizing inputs and validating model outputs to prevent malicious use. - Discover the unique security considerations for systems using Retrieval-Augmented Generation (RAG). - Apply a basic threat modeling framework to your own LLM-based projects. The course begins by explaining the common attack vectors and the mindset of an attacker. From there, we will walk through practical, text-based examples of defensive strategies you can apply to protect your applications. This course is designed for beginners. No prior experience in cybersecurity is required, but a basic familiarity with LLMs is helpful. It's ideal for developers, product managers, and technical leaders looking to secure their AI integrations. Start learning how to build more secure and trustworthy AI applications today.

Eye-opening — I can finally spot prompt injection attempts before they reach my app.

사내 챗봇에 사용자 입력을 그대로 넣고 있었는데 이 강의 듣고 나서 얼마나 위험했는지 깨달았어요. 프롬프트 인젝션이랑 탈옥 공격을 실제 예시로 보여줘서 이해가 빨랐고, 시스템 프롬프트와 사용자 입력을 분리하는 방법이 특히 유용했습니다. 출력 필터링과 입력 검증을 어떻게 함께 써야 하는지도 잘 정리돼 있었어요. 막연하게 알던 LLM 보안을 이제는 체크리스트로 점검할 수 있게 됐습니다. 실무에 바로 적용하고 있어요.
