Ensure That RSASHA1 Is Not Used for the Key-Signing Key in Cloud DNS DNSSEC

MoyenneNiveau 1Revue manuellegcp

Description

NOTE: Currently, the SHA1 algorithm has been removed from general use by Google, and, if being used, needs to be whitelisted on a project basis by Google and will also, therefore, require a Google Cloud support contract. DNSSEC algorithm numbers in this registry may be used in CERT RRs. Zone signing (DNSSEC) and transaction security mechanisms (SIG(0) and TSIG) make use of particular subsets of these algorithms. The algorithm used for key signing should be a recommended one and it should be strong. Domain Name System Security Extensions (DNSSEC) algorithm numbers in this registry may be used in CERT RRs. Zonesigning (DNSSEC) and transaction security mechanisms (SIG(0) and TSIG) make use of particular subsets of these algorithms.

From Google Cloud CLI Ensure the property algorithm for keyType keySigning is not using RSASHA1. gcloud dns managed-zones describe ZONENAME -- format="json(dnsName,dnssecConfig.state,dnssecConfig.defaultKeySpecs)"

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

From Google Cloud CLI 1. If it is necessary to change the settings for a managed zone where it has been enabled, DNSSEC must be turned off and re-enabled with different settings. To turn off DNSSEC, run the following command: gcloud dns managed-zones update ZONE_NAME --dnssec-state off 2. To update key-signing for a reported managed DNS Zone, run the following command: gcloud dns managed-zones update ZONE_NAME --dnssec-state on --ksk-algorithm KSK_ALGORITHM --ksk-key-length KSK_KEY_LENGTH --zsk-algorithm ZSK_ALGORITHM - -zsk-key-length ZSK_KEY_LENGTH --denial-of-existence DENIAL_OF_EXISTENCE Supported algorithm options and key lengths are as follows.
