Journalisation et journalisation d'audit (LOG et AL)

Les journaux d'audit Logging et Audit Logging (LOG et AL) dans Google Distributed Cloud (GDC) avec isolation physique vous permettent de suivre les opérations d'administration et d'accès aux données pour les pipelines de journalisation et de surveillance dans les charges de travail de l'organisation. Les journaux d'audit Kubernetes et l'enregistreur d'audit d'observabilité enregistrent l'identité de l'utilisateur ou du service, la ressource cible et les champs de charge utile JSON pour les ressources personnalisées LoggingTarget, LoggingRule et SIEMOrgForwarder, ainsi que pour les requêtes Loki et Prometheus.
