Defending Against Prompt Injection

Recognize and mitigate prompt injection attacks where retrieved or user content hijacks your LLM instructions.

What Is Prompt Injection?

Prompt injection is when text the model reads contains instructions that override your own. In RAG, malicious content can hide inside the very documents you retrieve.

Direct vs. Indirect

Direct injection comes from the user input. Indirect injection is hidden in retrieved documents, web pages, or files the model ingests later.
