AWS Shield Advanced now supports resource tagging

AWS Shield Advanced now supports tagging of protected resources and protection groups. You can use tagging to restrict the ability to create or modify protections to sensitive resources via IAM policies, or to organize and track your AWS Shield Advanced costs at the tag level. Resource tagging allows you to define custom names for protected application resources, such as Amazon Elastic Compute Cloud (EC2), Elastic Load Balancing (ELB), Amazon CloudFront, AWS Global Accelerator and Amazon Route 53.
