What CGPulse checks
A resource passes this rule when allowExternalPrincipals must equal false. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Disable external principals to restrict resource sharing to within the AWS Organization. In AWS Console: RAM > Resource shares > Edit > uncheck Allow external principals. See: https://docs.aws.amazon.com/ram/latest/userguide/working-with-sharing.html
Terraform
resource "aws_ram_resource_share" "{name}" {
allow_external_principals = false
}
