Security Center helps administrators inspect instance security posture and recommendations. Findings need an owner, a risk assessment, and a controlled remediation path. A recommendation isn't a guarantee that one setting will secure the whole business process. Check its scope and impact before applying it.
The shared responsibility model separates responsibilities among the service provider, supporting infrastructure arrangements, and the customer. Customer administrators still control users, roles, business data, application configuration, and appropriate access decisions. Hosting a platform doesn't remove those responsibilities. Review integrations and service accounts as part of the same access picture. Use nonproduction tests where a hardening change could disrupt business use, and retain evidence of the decision rather than treating a green indicator as a substitute for verification.
