# API Reference — Performing Oil & Gas Cybersecurity Assessment
|
|
|
|
## Libraries Used
|
|
- **csv**: Parse asset inventories and compliance questionnaires
|
|
- **pathlib**: File operations
|
|
|
|
## CLI Interface
|
|
```
|
|
python agent.py network --assets ot_inventory.csv
|
|
python agent.py compliance --csv iec62443_assessment.csv
|
|
python agent.py safety --assets ot_inventory.csv
|
|
python agent.py report --assets ot_inventory.csv [--compliance-csv iec62443.csv]
|
|
```
|
|
|
|
## Core Functions
|
|
|
|
### `assess_network_segmentation(asset_file)` — Purdue model zone validation
|
|
Checks assets against expected Purdue level placement. Flags zone mismatches and missing DMZ.
|
|
|
|
### `assess_iec62443_compliance(assessment_csv)` — IEC 62443 security level assessment
|
|
Compares achieved vs target Security Levels (SL1-SL4) per zone.
|
|
|
|
### `assess_safety_systems(asset_file)` — SIS/ESD security posture
|
|
Flags CRITICAL: SIS network-connected, remote access enabled, shared controller with process.
|
|
|
|
### `generate_assessment_report(...)` — Comprehensive sector assessment
|
|
|
|
## OT Asset Categories

|
|
| SCADA | CRITICAL | Level 2 |
|
|
| DCS | CRITICAL | Level 1-2 |
|
|
| SIS | CRITICAL | Level 0-1 |
|
|
| PLC/RTU | HIGH | Level 1 |
|
|
| HMI | HIGH | Level 2 |
|
|
| Historian | MEDIUM | Level 3 |
|
