Ensure Lambda function URLs use authentication
Lambda function URLs should use AWS_IAM authentication unless public access is explicitly required.
Security Impact
Function URLs with NONE auth type allow anyone to invoke the function.
How to Remediate
Configure function URL with AuthType: AWS_IAM. Use API Gateway for more sophisticated authentication.
