Uso de conjuntos de pilas de CloudFormation
importante
Respuesta frente a incidencias de seguridad de AWS no habilita las capacidades de contención de forma predeterminada; para ejecutar estas acciones de contención, primero debe conceder los permisos necesarios al servicio mediante roles. Puede crear estos roles de forma individual por cuenta o en toda la organización mediante la implementación de conjuntos de pilas de CloudFormation, que crean los roles necesarios.
Puede consultar instrucciones específicas sobre cómo crear un conjunto de pilas con permisos administrados por servicios.
A continuación se muestran plantillas de conjuntos de pilas para crear los roles AWSSecurityIncidentResponseContainment y AWSSecurityIncidentResponseContainmentExecution.
