# Feedser Connector Research – 2025-10-11
|
||
|
||
Snapshot of direct network checks performed on 2025-10-11 (UTC) for the national/vendor connectors in scope. Use alongside each module’s `TASKS.md` notes.
|
||
|
||
## ACSC (Australia)
|
||
- Enumerated feed slugs `/acsc/view-all-content/{alerts,advisories,news,publications,threats}/rss`; every endpoint negotiates HTTP/2 then aborts with `INTERNAL_ERROR` (curl exit 92). Forcing HTTP/1.1 hangs >600 s and sitemap/HTML fetches fail the same way.
|
||
- Next actions: prototype `SocketsHttpHandler` settings (`RequestVersionOrLower`, allow fallback to relay), capture successful headers from partner vantage (need retention + cache semantics), and keep `FEEDCONN-SHARED-HTTP2-001` open for downgrade work.
|
||
|
||
## CCCS (Canada)
|
||
- RSS endpoint (`https://cyber.gc.ca/api/cccs/rss/v1/get?...`) 301s to Atom feed (`/api/cccs/atom/v1/get?...`) with 50-entry window, HTML-heavy `<content>` fields, and no cache headers.
|
||
- Next actions: enumerate additional `feed` query values, sanitise inline HTML for DTO storage, and track retention depth via HTML pagination (`?page=`).
|
||
|
||
## CERT-Bund (Germany)
|
||
- `https://wid.cert-bund.de/content/public/securityAdvisory/rss` responds 200 without cookies (250-item window, German taxonomy). Detail links load an Angular SPA that fetches JSON behind session cookies.
|
||
- Next actions: script SPA cookie/bootstrap, discover JSON detail endpoint, and capture advisory schema for parser planning.
|
||
|
||
## KISA / KNVD (Korea)
|
||
- `https://knvd.krcert.or.kr/rss/securityInfo.do` and `/rss/securityNotice.do` return UTF-8 RSS (10-item window) with `detailDos.do?IDX=` links. No cookies required for feed fetch.
|
||
- Next actions: trace SPA detail requests to identify JSON endpoints, normalise Hangul content, and finalise localisation plan.
|
||
|
||
## BDU (Russia / FSTEC)
|
||
- Candidate endpoints (`https://bdu.fstec.ru/component/rsform/form/7-bdu?format=xml/json`) return 403/404; TLS chain requires Russian Trusted Sub CA and WAF expects additional headers.
|
||
- Next actions: acquire official PEM chain, point `feedser:httpClients:source.bdu:trustedRootPaths` (or `feedser:sources:bdu:http:trustedRootPaths`) at the Offline Kit PEM, keep `allowInvalidCertificates=false`, script session bootstrap, then capture RSS/HTML schema for parser work.
|
||
|
||
## NKTsKI / cert.gov.ru (Russia)
|
||
- `https://cert.gov.ru/rss/advisories.xml` served via Bitrix returns 403/404 even with `Accept-Language: ru-RU`; TLS chain also requires Russian trust anchors.
|
||
- Next actions: source trust store, configure `feedser:httpClients:source.nkcki:trustedRootPaths` (Offline Kit root via `feedser:offline:root`), prepare proxy fallback, and once accessible document taxonomy/retention plus attachment handling.
|
||
|
||
## CISA ICS (United States)
|
||
- `curl -I https://www.cisa.gov/cybersecurity-advisories/ics-advisories.xml` returns HTTP 403 + `x-reference-error` (Akamai). Same for legacy feed paths.
|
||
- Next actions: secure GovDelivery access, document token rotation, and build HTML/email fallback with throttling.
|
||
|
||
## Cisco PSIRT
|
||
- `https://api.cisco.com/security/advisories/latest` returns `ERR_596_SERVICE_NOT_FOUND` when unauthenticated. openVuln REST requires Mashery OAuth (client credentials) with quotas ~5 req/s, 30/min, 5 000/day; supports `pageIndex/pageSize` pagination.
|
||
- Next actions: register OAuth app, capture pagination/delta parameters, and compare API vs RSS coverage.
|
||
|
||
## Microsoft MSRC
|
||
- REST endpoint (`https://api.msrc.microsoft.com/sug/v2.0/en-US/vulnerabilities`) requires Azure AD token + `api-version` (current `2024-08-01`) and supports delta filters (`lastModifiedStartDateTime`). CVRF ZIP remains available for offline use.
|
||
- Next actions: finalise AAD app registration, implement token cache, and design combined REST+CVRF ingestion path for determinism.
