# ICSCISA / KISA Feed Provenance Notes (2025-11-19)
|
|
|
|
- Expected signing: not provided by sources; set `signature=null` and `skip_reason="unsigned"`.
|
|
- Hashing: sha256 of raw advisory payload before normalization.
|
|
- Transport: HTTPS; mirror to internal cache; record `fetched_at` UTC and `source_url`.
|
|
- Verification: compare hash vs previous run; emit delta report.
|
|
- Staleness guard: alert if `fetched_at` >14 days.
