[dns-esp] Se publicó la RFC 8976 (Message Digest for DNS Zones: ZONEMD RR)

Esta es una excelente noticia !!! Y definitivamente algo que estaba "faltando" y era muy necesario. Básicamente con este nuevo RFC tenemos una forma de verificar que una zona que obtenemos de una transferencia (XFR) es exactamente igual a la que fue publicada (no sufrió ninguna modificación). Esto es sumamente útil, por ejemplo, en los casos de implementación de Hyperlocal para confirmar que la copia de la zona raíz que obtenemos coincide con la original... completando así la seguridad que agrega DNSSEC en esos casos. Fraterno saludo, Nico ---------- Forwarded message --------- De: <rfc-editor(a)rfc-editor.org> Date: mié, 10 de feb. de 2021 a la(s) 03:20 Subject: RFC 8976 on Message Digest for DNS Zones To: <ietf-announce(a)ietf.org>, <rfc-dist(a)rfc-editor.org> Cc: <drafts-update-ref(a)iana.org>, <dnsop(a)ietf.org>, <rfc-editor(a)rfc-editor.org> A new Request for Comments is now available in online RFC libraries. RFC 8976 Title: Message Digest for DNS Zones Author: D. Wessels, P. Barber, M. Weinberg, W. Kumari, W. Hardaker Status: Standards Track Stream: IETF Date: February 2021 Mailbox: dwessels(a)verisign.com, pbarber(a)verisign.com, matweinb(a)amazon.com, warren(a)kumari.net, ietf(a)hardakers.net Pages: 31 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-dnsop-dns-zone-digest-14.txt URL: https://www.rfc-editor.org/info/rfc8976 DOI: 10.17487/RFC8976 This document describes a protocol and new DNS Resource Record that provides a cryptographic message digest over DNS zone data at rest. The ZONEMD Resource Record conveys the digest data in the zone itself. When used in combination with DNSSEC, ZONEMD allows recipients to verify the zone contents for data integrity and origin authenticity. This provides assurance that received zone data matches published data, regardless of how the zone data has been transmitted and received. When used without DNSSEC, ZONEMD functions as a checksum, guarding only against unintentional changes. ZONEMD does not replace DNSSEC: DNSSEC protects individual RRsets (DNS data with fine granularity), whereas ZONEMD protects a zone's data as a whole, whether consumed by authoritative name servers, recursive name servers, or any other applications. As specified herein, ZONEMD is impractical for large, dynamic zones due to the time and resources required for digest calculation. However, the ZONEMD record is extensible so that new digest schemes may be added in the future to support large, dynamic zones. This document is a product of the Domain Name System Operations Working Group of the IETF. This is now a Proposed Standard.
