# Concelier KISA Connector Operations
|
||
|
||
Operational guidance for the Korea Internet & Security Agency (KISA / KNVD) connector (`source:kisa:*`). Pair this with the engineering brief in `docs/dev/kisa_connector_notes.md`.
|
||
|
||
## 1. Prerequisites
|
||
|
||
- Outbound HTTPS (or mirrored cache) for `https://knvd.krcert.or.kr/`.
|
||
- Connector options defined under `concelier:sources:kisa`:
|
||
|
||
```yaml
|
||
concelier:
|
||
sources:
|
||
kisa:
|
||
feedUri: "https://knvd.krcert.or.kr/rss/securityInfo.do"
|
||
detailApiUri: "https://knvd.krcert.or.kr/rssDetailData.do"
|
||
detailPageUri: "https://knvd.krcert.or.kr/detailDos.do"
|
||
maxAdvisoriesPerFetch: 10
|
||
requestDelay: "00:00:01"
|
||
failureBackoff: "00:05:00"
|
||
```
|
||
|
||
> Ensure the URIs stay absolute—Concelier adds the `feedUri`/`detailApiUri` hosts to the HttpClient allow-list automatically.
|
||
|
||
## 2. Staging Smoke Test
|
||
|
||
1. Restart the Concelier workers so the KISA options bind.
|
||
2. Run a full connector cycle:
|
||
- CLI: `stella db jobs run source:kisa:fetch --and-then source:kisa:parse --and-then source:kisa:map`
|
||
- REST: `POST /jobs/run { "kind": "source:kisa:fetch", "chain": ["source:kisa:parse", "source:kisa:map"] }`
|
||
3. Confirm telemetry (Meter `StellaOps.Concelier.Connector.Kisa`):
|
||
- `kisa.feed.success`, `kisa.feed.items`
|
||
- `kisa.detail.success` / `.failures`
|
||
- `kisa.parse.success` / `.failures`
|
||
- `kisa.map.success` / `.failures`
|
||
- `kisa.cursor.updates`
|
||
4. Inspect logs for structured entries:
|
||
- `KISA feed returned {ItemCount}`
|
||
- `KISA fetched detail for {Idx} … category={Category}`
|
||
- `KISA mapped advisory {AdvisoryId} (severity={Severity})`
|
||
- Absence of warnings such as `document missing GridFS payload`.
|
||
5. Validate MongoDB state:
|
||
- `raw_documents.metadata` has `kisa.idx`, `kisa.category`, `kisa.title`.
|
||
- DTO store contains `schemaVersion="kisa.detail.v1"`.
|
||
- Advisories include aliases (`IDX`, CVE) and `language="ko"`.
|
||
- `source_states` entry for `kisa` shows recent `cursor.lastFetchAt`.
|
||
|
||
## 3. Production Monitoring
|
||
|
||
- **Dashboards** – Add the following Prometheus/OTEL expressions:
|
||
- `rate(kisa_feed_items_total[15m])` versus `rate(concelier_source_http_requests_total{concelier_source="kisa"}[15m])`
|
||
- `increase(kisa_detail_failures_total{reason!="empty-document"}[1h])` alert at `>0`
|
||
- `increase(kisa_parse_failures_total[1h])` for storage/JSON issues
|
||
- `increase(kisa_map_failures_total[1h])` to flag schema drift
|
||
- `increase(kisa_cursor_updates_total[6h]) == 0` during active windows → warn
|
||
- **Alerts** – Page when `rate(kisa_feed_success_total[2h]) == 0` while other connectors are active; back off for maintenance windows announced on `https://knvd.krcert.or.kr/`.
|
||
- **Logs** – Watch for repeated warnings (`document missing`, `DTO missing`) or errors with reason tags `HttpRequestException`, `download`, `parse`, `map`.
|
||
|
||
## 4. Localisation Handling
|
||
|
||
- Hangul categories (for example `취약점정보`) flow into telemetry tags (`category=…`) and logs. Dashboards must render UTF‑8 and avoid transliteration.
|
||
- HTML content is sanitised before storage; translation teams can consume the `ContentHtml` field safely.
|
||
- Advisory severity remains as provided by KISA (`High`, `Medium`, etc.). Map-level failures include the severity tag for filtering.
|
||
|
||
## 5. Fixture & Regression Maintenance
|
||
|
||
- Regression fixtures: `src/Concelier/__Tests/StellaOps.Concelier.Connector.Kisa.Tests/Fixtures/kisa-feed.xml` and `kisa-detail.json`.
|
||
- Refresh via `UPDATE_KISA_FIXTURES=1 dotnet test src/Concelier/__Tests/StellaOps.Concelier.Connector.Kisa.Tests/StellaOps.Concelier.Connector.Kisa.Tests.csproj`.
|
||
- The telemetry regression (`KisaConnectorTests.Telemetry_RecordsMetrics`) will fail if counters/log wiring drifts—treat failures as gating.
|
||
|
||
## 6. Known Issues
|
||
|
||
- RSS feeds only expose the latest 10 advisories; long outages require replay via archived feeds or manual IDX seeds.
|
||
- Detail endpoint occasionally throttles; the connector honours `requestDelay` and reports failures with reason `HttpRequestException`. Consider increasing delay for weekend backfills.
|
||
- If `kisa.category` tags suddenly appear as `unknown`, verify KISA has not renamed RSS elements; update the parser fixtures before production rollout.
