How to Prevent Prompt Injection
A prompt injection occurs when an attacker manipulates input to your AI system, overriding its instructions. To prevent prompt injection, you need a layered approach: separate system instructions from user input, validate user input before it reaches the model, monitor model outputs for anomalies, enforce least-privilege access for AI agents, and protect the data layer so sensitive information never reaches the model in a readable form. No single fix is enough.
