# Industrial Specification: Policy Enforcement Point

## 1. Technical Definition
A component within an Access Control Module that enforces security policies by granting or denying access requests based on authorization decisions.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC input signal range, 24 VDC power supply ±10%**. Failure boundary: **Input signal exceeding 5.5 VDC causes comparator saturation, power supply below 21.6 VDC causes relay dropout**, Mechanism: **Semiconductor junction breakdown at 5.5 VDC reverse bias, electromagnetic relay coil de-energization below 21.6 VDC holding voltage**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electromagnetic interference from adjacent 480V AC motor starters | 8 | False access grants due to comparator latch-up at 3.2 VDC noise threshold | Shielded twisted-pair cabling with 100 dB attenuation at 60 Hz, ferrite chokes on all I/O lines |
| Condensation accumulation in unsealed enclosures at 85% relative humidity | 8 | Signal path corrosion increasing contact resistance beyond 50 Ω threshold | IP67-rated NEMA 4X enclosures with silica gel desiccant packs maintaining &lt;30% internal humidity |

### Q: What is a Policy Enforcement Point in computer manufacturing?
**A**: A Policy Enforcement Point (PEP) is a hardware component within access control systems that enforces security policies by granting or denying access requests based on authorization decisions from policy decision points, typically implemented using semiconductor and PCB technology.

### Q: How does a PEP integrate with manufacturing systems?
**A**: The PEP integrates via its Request Interceptor, Policy Decision Interface, and Enforcement Engine components to monitor access requests in manufacturing environments, ensuring only authorized personnel and systems can access sensitive production data and control systems.

### Q: What are the key specifications for industrial PEP hardware?
**A**: Key specifications include semiconductor-based processing (typically silicon), PCB construction for durability, real-time enforcement capabilities, compatibility with industry security protocols, and robust interfaces for integration with manufacturing access control systems.
