Ensure that node certificates are rotated as appropriate

MediaNivel 1Revisión manualdocker

Descripción

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.
