# API Reference: OT Conduit Security Assessment Agent
|
|
|
|
## Dependencies
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| (stdlib only) | Python 3.8+ | Socket-based OT port scanning, JSON processing |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python scripts/agent.py \
|
|
--targets 10.10.1.1 10.10.1.2 \
|
|
--controls-data /assessments/conduit_controls.json \
|
|
--output-dir /reports/
|
|
```
|
|
|
|
## Functions
|
|
|
|
### `scan_ot_ports(target, timeout) -> list`
|
|
TCP connect scan for 9 OT protocol ports (Modbus 502, S7comm 102, OPC UA 4840, etc.).
|
|
|
|
### `assess_conduit_controls(responses) -> list`
|
|
Evaluates 8 IEC 62443-aligned conduit controls: jump server, MFA, session recording, segmentation, encryption.
|
|
|
|
### `compute_conduit_risk_score(control_results, open_ports) -> dict`
|
|
Calculates risk score (0-100) penalizing for exposed OT ports and missing controls.
|
|
|
|
### `generate_report(targets, responses) -> dict`
|
|
Full assessment with port scanning, control evaluation, and risk scoring.
