# DLP Policy Engine
## Purpose
`aw-server/dlp-policy-engine` centralizes DLP policy lifecycle for `AWatch-rus` Windows endpoints.
It does not replace endpoint-local safety. Endpoints can run in:
- `local`
- `server`
- `cached` fallback after server outage
## API
Base URL:
```text
http://<aw-server>:5601
```
Routes:
- `GET /healthz`
- `GET /api/0/dlp/policies`
- `POST /api/0/dlp/policies`
- `GET /api/0/dlp/policies/active`
- `POST /api/0/dlp/policies/rollback`
- `GET /api/0/dlp/policies/{id}`
- `PUT /api/0/dlp/policies/{id}`
- `POST /api/0/dlp/policies/{id}/activate`
- `DELETE /api/0/dlp/policies/{id}`
## Policy create example
```json
{
"name": "base-windows-policy",
"description": "Primary DLP policy for pilot endpoints",
"activate": true,
"actor": "ansible",
"policy": {
"version": 1,
"defaults": {
"enabled": true,
"cooldownSeconds": 300,
"action": "alert",
"severity": "medium"
},
"endpoint": {
"clipboard": [],
"usb": [],
"print": []
}
}
}
```
## Active policy response
```json
{
"active": true,
"policyId": 1,
"name": "base-windows-policy",
"version": 3,
"checksum": "sha256...",
"updatedAtUtc": "2026-05-11T12:00:00Z",
"policy": {
"version": 1,
"defaults": {
"enabled": true,
"cooldownSeconds": 300,
"action": "alert",
"severity": "medium"
},
"endpoint": {
"clipboard": [],
"usb": [],
"print": []
}
}
}
```
## Deployment Notes
- Service runs as `aw-dlp-policy-engine.service`.
- SQLite path is controlled by `AW_DLP_POLICY_ENGINE_DB_PATH`.
- Default port is `5601`.
- Endpoints should use `server` mode only after `GET /healthz` and `GET /api/0/dlp/policies/active` are confirmed.
