FOR CHIEF INFORMATION SECURITY OFFICERS
LUIPM is fail-closed by default on every action class. Integrity-Flux monitors reasoning drift in real time. Prompt injection that corrupts reasoning state cannot unlock the gateway.
THE THREAT MODEL
Attackers can inject instructions into AI inputs. The model may reason that the injected instruction should be executed. Without an external enforcement boundary, the injected action fires.
As models are fine-tuned or encounter adversarial inputs, their reasoning may shift. The model may generate actions that violate your security policies.
If a model is stolen, fine-tuned, or poisoned, it may generate harmful actions. Without an enforcement boundary, there is no protection.
Third-party AI models may have hidden behaviors. Your policies cannot control what you do not know about.
THE DEFENSE
If any predicate fails, the action is blocked. No compensations. No human override. Γ > 0 means SAFE_STATE.
I_φ tracks drift in reasoning patterns. If the model's behavior is changing, the predicate tightens automatically. Suspicious reasoning gets blocked earlier.
Each action class has its own predicate set. Privilege creep cannot happen because each action is independently gated.
An injected instruction that corrupts model reasoning increases I_φ. The model's credibility score drops. Subsequent actions face stricter predicates.
The model cannot grant its own permit. The AI is sandboxed from the enforcement boundary. Even if the model is compromised, it cannot override LUIPM.
DETECTION & ALERTING
When predicate failures spike, you get alerts. A sudden increase in denials may indicate a prompt injection attack or model drift.
Integrity-Flux trending upward signals reasoning instability. You can take defensive action before the model goes rogue.
New action types emerging? Actions targeting unusual resources? Lakhowal flags them for SecOps review.
If an action violates your policies, you know immediately. Not tomorrow. Not after the regulator calls. Now.
ARCHITECTURE
LUIPM sits in-path. Every action is evaluated. Fail-closed enforcement.
Your application wraps AI action calls. LUIPM intercepts and evaluates locally.
Non-blocking observer. See what permits would be issued without affecting production.
No outbound calls. LUIPM runs in your VPC with no external dependencies.
Shadow Mode gives you real-time visibility into what LUIPM would block. No code changes. No production risk. Five to ten days to deploy.
