Most AI security issues are not novel. They are old software security mistakes with a new interface layer and a few more ways to surprise the operator.
The checklist below is intentionally short. If a team cannot complete these steps, the system is probably not ready for production use.
1. Define the trust boundary
Decide exactly what the model can see and what it can change.
- Does it read private data?
- Can it call tools?
- Can it write files?
- Can it trigger notifications or external requests?
If the answer is yes, those actions need a review path and a revocation path.
2. Minimize the input surface
The model should only receive the data it needs.
- trim system prompts
- avoid dumping whole documents when a summary will do
- redact secrets before the prompt layer
- separate user-controlled text from instructions
Prompt injection gets easier when the input boundary is vague.
3. Put tools behind policy
Tool access is the part that matters most in real systems. A model with broad write access is not a chatbot anymore; it is a privileged automation engine.
Use:
- narrow scopes
- explicit allow lists
- human approval for destructive actions
- structured logging for every tool call
4. Log the decision path
When AI systems fail, the debug trail is usually weak. Record:
- prompt version
- tool calls
- policy decisions
- final output
- user context where appropriate
That makes incident review possible without exposing the entire data set.
5. Assume the model will be manipulated
The baseline assumption should be that someone will try to push the model into doing the wrong thing.
The defense is not perfection. It is containment:
- bounded permissions
- rate limits
- clear fallbacks
- fast rollback
Outcome
AI features are safest when they are treated as constrained systems, not as magical helpers. The more power the feature has, the closer it should sit to normal security engineering discipline.
