Confinement uniquement
Utilisez ce modèle si vous souhaitez que le service isole les ressources compromises lors d'un incident, mais que vous n'avez pas besoin de collecter des données médico-légales auprès des instances en cours d'exécution.
Ce modèle crée deux rôles IAM :
-
AWSSecurityIncidentResponseContainment— Supposé par Réponse aux incidents de sécurité AWS pour initier des flux de travail d'automatisation du confinement via AWS Systems Manager. -
AWSSecurityIncidentResponseContainmentExecution— Supposé par AWS Systems Manager pour exécuter les actions de confinement sur vos ressources.
Ces rôles permettent trois actions de confinement : isoler les instances Amazon EC2 du trafic réseau, révoquer l'accès principal IAM et restreindre l'accès au compartiment Amazon S3.
