Trabalho com o CloudFormation StackSets
Importante
A AWS Security Incident Response não habilita, por padrão, as funcionalidades de contenção. Para que essas ações de contenção possam ser executadas, é necessário conceder previamente as permissões necessárias ao serviço usando perfis. Você tem a opção de criar esses perfis separadamente em cada conta ou implementá-los em toda a sua organização por meio do CloudFormation StackSets, que se encarrega de criar os perfis requeridos.
Você pode encontrar instruções específicas sobre como criar um conjunto de pilhas com permissões gerenciadas pelo serviço.
A seguir, são apresentados os conjuntos de pilhas de modelo para criar os perfis AWSSecurityIncidentResponseContainment e AWSSecurityIncidentResponseContainmentExecution.
