What you'll learn
- Identify and explain all 10 OWASP LLM 2025 vulnerabilities including System Prompt Leakage and Vector & Embedding Weaknesses
- Analyze and execute prompt injection attacks, direct, indirect, multimodal, and agentic, using real-world scenarios
- Defend LLM applications against sensitive information disclosure, training data extraction, and RAG-sourced data leakage
- Threat model LLM applications using STRIDE, MITRE ATLAS, and the OWASP LLM risk framework
- Implement secure RAG pipelines with proper vector database access controls and embedding integrity checks
- Apply least-privilege and human-in-the-loop patterns to prevent excessive agency in AI agents and MCP-connected systems
- Evaluate LLM supply chain risk and build an AI Software Bill of Materials (SBOM) for enterprise deployments
- Build defense-in-depth architecture covering input validation, output sanitization, secrets management, and monitoring
About this course
LLM-powered applications are being deployed across finance, healthcare, legal, and enterprise software at scale, and attackers are already exploiting them. This course is a comprehensive practitioner-built guide to the OWASP Top 10 for LLM Applications (2025 edition).
You will work through all 10 OWASP LLM risks in structured depth, from LLM architecture fundamentals through every vulnerability class with real attack scenarios, finishing with a secure design framework you can apply immediately.
The 2025-specific risks receive special attention: System Prompt Leakage and Vector & Embedding Weaknesses reflect how real-world LLM deployments have evolved. The final section covers threat modeling, reference architecture, and compliance mapping to EU AI Act, NIST AI RMF, GDPR, and SOC 2.
By the end of this course you will be able to threat model any LLM application, identify and demonstrate every OWASP LLM risk, and implement the architectural controls that prevent them.
Requirements
- •Basic understanding of how web applications work (HTTP, APIs, client-server model)
- •Familiarity with at least one programming language (Python preferred but not required)
- •General awareness of cybersecurity concepts such as authentication, injection attacks, and access control
- •No prior AI or machine learning experience needed, LLM architecture is explained from the ground up
