An online camera can still be pointed wrong, obscured, unfocused, reflecting infrared, recording the wrong stream, or producing unusable exports. Audit image purpose, scene, hardware, recording, time, analytics, and evidence workflow together.

A configured standby does not prove that all cameras will transfer, record, remain viewable, merge cleanly, and return under production load. Validate the exact failure, takeover, degraded operation, recovery, and evidence path.

A cardholder export shows what the system grants, not what a person still needs. Have accountable role and area owners affirm required access, challenge exceptions, remove stale grants, and verify the controller received the change.

Door behavior during loss of server, network, controller communication, reader, lock power, or fire-interface state must be designed—not discovered. Test each distinct door safely against approved life-safety and security requirements.

A mechanical key can bypass identity, schedules, revocation, alarms, and audit trails. Govern high-impact keys with named ownership, least privilege, controlled issue, inventory, return, loss response, and periodic proof of custody.

A call button that rings once is not a commissioned entry workflow. Verify intelligible two-way audio, visual and identity context, correct release, network and power loss, unanswered-call escalation, accessibility, privacy, and operator action.

Biometric matching has false matches and false non-matches, while spoofing, environment, enrollment, demographics, privacy, and fallback shape real risk. Pilot the actual population and workflow before treating a biometric as trusted access.

Microsoft Entra authentication context can invoke Conditional Access for a sensitive action inside a capable application. Use it to add risk-appropriate step-up without assuming it protects unsupported paths or replaces baseline access policy.

Microsoft Entra cross-tenant access settings govern inbound and outbound B2B relationships and trust in external MFA or device claims. Inventory real partners, defaults, applications, and lifecycle before broad collaboration becomes the policy.

Blocking sign-in and revoking refresh tokens are important, but existing access and application sessions can end on different timelines. Run a documented containment workflow and verify effective loss of access across supported services and independent applications.
