GCP authentication

Prowler will use by default your User Account credentials, you can configure it using:

  • gcloud init to use a new account
  • gcloud config set account <account> to use an existing account

Then, obtain your access credentials using: gcloud auth application-default login

Otherwise, you can generate and download Service Account keys in JSON format (refer to https://cloud.google.com/iam/docs/creating-managing-service-account-keys) and provide the location of the file with the following argument:

prowler gcp --credentials-file path
Note

prowler will scan the GCP project associated with the credentials.

Prowler will follow the same credentials search as Google authentication libraries:

  1. GOOGLE_APPLICATION_CREDENTIALS environment variable
  2. User credentials set up by using the Google Cloud CLI
  3. The attached service account, returned by the metadata server

Those credentials must be associated to a user or service account with proper permissions to do all checks. To make sure, add the Viewer role to the member associated with the credentials.

GCP Service APIs

Prowler will use the Google Cloud APIs to get the information needed to perform the checks. Make sure that the following APIs are enabled in the project:

  • apikeys.googleapis.com
  • artifactregistry.googleapis.com
  • bigquery.googleapis.com
  • sqladmin.googleapis.com
  • storage.googleapis.com
  • compute.googleapis.com
  • dataproc.googleapis.com
  • dns.googleapis.com
  • containerregistry.googleapis.com
  • container.googleapis.com
  • iam.googleapis.com
  • cloudkms.googleapis.com
  • logging.googleapis.com

You can enable them automatically using our script enable_apis_in_projects.sh
