Red-teaming means deliberately trying to make the system misbehave: leak data, ignore rules, take unsafe actions. Doing it internally lets you fix issues before users or attackers find them.
A practical plan
- Define what 'failure' means: data exposure, policy breach, unsafe action, harmful output.
- Assemble a mixed group — security, domain experts and someone unfamiliar with the design.
- Try instruction override, hidden instructions in documents, requests for other users' data and misuse of tools.
- Record each attempt, the result and a severity.
- Fix, add the cases to your test set and re-run.
Make the attack cases a permanent regression suite. Any change to the model, prompt or tools should pass them again.
