Ensure that node certificates are rotated as appropriate
Описание
You should rotate swarm node certificates in line with your organizational security policy. Docker Swarm uses TLS for clustering operations between its nodes. Certificate rotation ensures that in an event such as a compromised node or key, it is difficult to impersonate a node. Reported as a manual review item: the audit needs a site-specific judgement.
Как проверяется
Метод проверки: Ручная проверка
Run one of the commands below and ensure that the node certificate Expiry Duration is set as appropriate. docker info | grep "Expiry Duration" docker info --format 'NodeCertExpiry: {{ .Swarm.Cluster.Spec.CAConfig.NodeCertExpiry }}'
Как исправляется
Метод исправления: Рекомендация или патч инфраструктуры
You should run the command to set the desired expiry time on the node certificate. For example: docker swarm update --cert-expiry 48h
