How to protect RAG from prompt injection and unwanted content?

To protect Retrieval-Augmented Generation (RAG) from prompt injection and unwanted content, several approaches are used:

• Filtering and validation of input data: restrict or sanitize user input to exclude malicious or manipulative commands.
• Separation of context: distinguish user input from system instructions to prevent interference with the generation logic.
• Use of safe prompt templates: predefined and verified templates that minimize the possibility of injecting unwanted instructions.
• Monitoring and logging: track anomalies in requests and responses for quick detection and response to attacks.
• Restricting access to data sources: control which documents and data are used for search to exclude malicious content.

Together, these measures help reduce prompt injection risks and ensure the quality and safety of RAG system responses.
