GCP BigQuery is a managed data warehousing solution. Most of the data stored in BigQuery are accessible in tables. When defining a dataset, access roles and groups can be specified. If the "allAuthenticatedUsers" special group is used, all GCP users can access the data stored in the concerned BigQuery dataset.


  • Data exposure
  • Data loss

Remediation guidelines#

Avoid using the special groups 'allAuthenticatedUsers' and 'allUsers',prefer specifying precise groups within the targeted organization.
