# Concelier FSTEC BDU Connector - Operations Runbook

_Last updated: 2026-01-16_

## 1. Overview
The FSTEC BDU connector ingests the Russian BDU vulnerability database and maps entries to canonical IDs.

## 2. Authentication
- No authentication required for public feeds unless a regional mirror enforces access controls.

## 3. Configuration (`concelier.yaml`)
```yaml
concelier:
  sources:
    fstec-bdu:
      baseUri: "<fstec-bdu-feed-base>"
      maxDocumentsPerFetch: 20
      fetchTimeout: "00:00:45"
      requestDelay: "00:00:00"
```

## 4. Offline and air-gapped deployments
- Mirror BDU data into the Offline Kit and repoint `baseUri` to the mirror.

## 5. Common failure modes
- Regional mirror availability.
- Non-standard identifier formats.
