Ensure That Cloud KMS Cryptokeys Are Not Anonymously or Publicly Accessible
Beschreibung
It is recommended that the IAM policy on Cloud KMS cryptokeys should restrict anonymous and/or public access. Granting permissions to allUsers or allAuthenticatedUsers allows anyone to access the dataset. Such access might not be desirable if sensitive data is stored at the location. In this case, ensure that anonymous and/or public access to a Cloud KMS cryptokey is not allowed.

Behebungsmethode: Anleitung oder Infrastruktur-Patch
From Google Cloud CLI 1. List all Cloud KMS Cryptokeys. gcloud kms keys list --keyring=[key_ring_name] --location=global -- format=json | jq '.[].name' 2. Remove IAM policy binding for a KMS key to remove access to allUsers and allAuthenticatedUsers using the below command. gcloud kms keys remove-iam-policy-binding [key_name] -- keyring=[key_ring_name] --location=global --member='allAuthenticatedUsers' -- role='[role]' gcloud kms keys remove-iam-policy-binding [key_name] -- keyring=[key_ring_name] --location=global --member='allUsers' --role='[role]'
