- Map OWASP risks to real product failures.
- Identify where an LLM app breaks: input, retrieval, tool, output, or dependency.
- Design minimum controls for each common risk.
Practical mapping
- Prompt injection: the user or a document tries to change the instructions.
- Sensitive data: the model reveals secrets, PII, tokens, contracts, or another user's information.
- Output handling: a model response is executed or rendered without validation.
- Supply chain: a model, dataset, package, or plugin is tampered with or uncontrolled.
- Excessive agency: the agent can send, delete, purchase, or modify without sufficient permissions.
