Harden an AI System Against Injection and Misuse
Architectural controls that survive a manipulated model.
/ quick answer
Assume the model can be turned against you and remove its ability to do damage. Architectural controls that survive a manipulated model.
- 01Map every tool the model can reach and classify read / write / irreversible.
- 02Remove generic escape hatches: raw SQL, shell, arbitrary HTTP.
- 03Enforce authorisation server-side, per user, on every call — never in the prompt.
- 04Treat all retrieved content as hostile input; never let it change the agent's goal.
- 05Filter output for secrets, tokens and PII before it leaves the system.
- 06Require approval for money movement, deletions and external communication.
- 07Log every call with user, args and result; alert on anomalous patterns.
- 08Record the system in the AI register with an owner and a review date.

The vocabulary this page depends on.
- →AI Security
AI security protects systems where the model is an untrusted decision-maker acting on untrusted input with real tool access.
- →Prompt Injection
An attack where hostile input hijacks the LLM's instructions, causing it to leak data or misbehave.
- →AI Governance
AI governance is the set of policies, records and reviews that make an organisation's AI use accountable and auditable.
- →Jailbreak
A prompt crafted to bypass a model's safety alignment.

- →Platform Catches a 19% Quality Drop Before Users Did
Continuous sampling and evals caught silent degradation after a model update.

Alerting on the user's own wallet activity caught an unauthorised approval attempt and forced an approval cleanup that removed 14 standing allowances.
Comparisons & alternatives
Pick between the options.
- →Model-Graded Evals vs Assertion Evals
Assertions are cheap, fast and objective; model grading captures quality you cannot express as a rule.
- →Hot Wallet vs Cold Wallet
Hot wallets trade convenience for exposure; cold wallets trade friction for a signing key that never touches an internet-connected device.
- →Rabby vs OKX Web3 Wallet
Rabby is the safety-focused EVM wallet with pre-transaction simulation; OKX Web3 Wallet trades some of that depth for multi-chain breadth and built-in trading.
