FOR CHIEF INFORMATION SECURITY OFFICERS
No Override. No Compensations. Fail-Closed.
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
Why AI Security Is Different
Prompt Injection
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.
Reasoning Drift
As models are fine-tuned or encounter adversarial inputs, their reasoning may shift. The model may generate actions that violate your security policies.
Model Compromise
If a model is stolen, fine-tuned, or poisoned, it may generate harmful actions. Without an enforcement boundary, there is no protection.
Supply Chain Risk
Third-party AI models may have hidden behaviors. Your policies cannot control what you do not know about.
THE DEFENSE
LUIPM as a Runtime Security Layer
🔒 Fail-Closed by Default
If any predicate fails, the action is blocked. No compensations. No human override. Γ > 0 means SAFE_STATE.
📊 Integrity-Flux Monitoring
I_φ tracks drift in reasoning patterns. If the model's behavior is changing, the predicate tightens automatically. Suspicious reasoning gets blocked earlier.
🎯 Predicate-Bounded IAM Scope
Each action class has its own predicate set. Privilege creep cannot happen because each action is independently gated.
🚫 Prompt Injection Defense
An injected instruction that corrupts model reasoning increases I_φ. The model's credibility score drops. Subsequent actions face stricter predicates.
⛓️ Causal Independence
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
See Threats Before They Become Incidents
Real-Time Denial Spikes
When predicate failures spike, you get alerts. A sudden increase in denials may indicate a prompt injection attack or model drift.
I_φ Drift Detection
Integrity-Flux trending upward signals reasoning instability. You can take defensive action before the model goes rogue.
Action Type Anomalies
New action types emerging? Actions targeting unusual resources? Lakhowal flags them for SecOps review.
Compliance Violations in Real Time
If an action violates your policies, you know immediately. Not tomorrow. Not after the regulator calls. Now.
ARCHITECTURE
Where LUIPM Sits in Your Stack
Option 1: Inline Gateway
LUIPM sits in-path. Every action is evaluated. Fail-closed enforcement.
Option 2: SDK-Wrapped
Your application wraps AI action calls. LUIPM intercepts and evaluates locally.
Option 3: Shadow Mode (Testing)
Non-blocking observer. See what permits would be issued without affecting production.
Option 4: Air-Gapped
No outbound calls. LUIPM runs in your VPC with no external dependencies.
