    Checks if Cloud Logging buckets are configured with a global location scope to ensure centralized log management and consistent access control.
  impact: |
    Logging buckets not configured with a global location can result in fragmented log storage and difficulty in maintaining centralized logging practices.
  remediation: |
    Update Cloud Logging buckets to use the global location scope to enable centralized logging across all regions.
