aws_lambda_permission Resource
Use the aws_lambda_permission
InSpec audit resource to test properties of a single AWS Lambda permission.
The AWS::Lambda::Permission
resource grants an AWS service or another account permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function.
For additional information, including details on parameters and properties, see the AWS documentation on AWS Lambda permission.
