Question 700
At Timberline Foods, the supply-chain assurance team is conducting a coordinated processing-plant assessment under requirements for food safety and secure logistics. An independent validation is requested for the original problem: An IoT data collector forwards telemetry to cloud endpoints using an unauthenticated plaintext protocol across an untrusted link. Which result BEST demonstrates successful remediation?
Explanation
Correct Answer
The cloud receiver accepts authorized devices only and network inspection cannot read protected telemetry payloads. The observable result demonstrates that the documented condition, An IoT data collector forwards telemetry to cloud endpoints using an unauthenticated plaintext protocol across an untrusted link. has been addressed. The planned remediation is: Apply mutual authentication or equivalent trusted identities and encrypted transport suited to device capabilities. This is a stronger validation than a saved ticket or unverified claim by Timberline Foods.
Incorrect Answers
A tabletop proves the incident team can reduce network exposure without creating an uncontrolled physical safety hazard. That observation would verify another scenario: An OT incident response playbook calls for immediately shutting down a controller that regulates a safety-critical process. The corrective step for that other scenario is: Coordinate containment with the process owner and safety procedures, using staged isolation where appropriate. But Timberline Foods is evaluating: An IoT data collector forwards telemetry to cloud endpoints using an unauthenticated plaintext protocol across an untrusted link. The necessary outcome is: The cloud receiver accepts authorized devices only and network inspection cannot read protected telemetry payloads.
Ordinary office devices cannot initiate controller administration while approved safety-monitoring flows continue. That observation would verify another scenario: A water treatment site uses one flat network for operator workstations, engineering laptops and process controllers. The corrective step for that other scenario is: Segment roles with explicit OT firewall rules and controlled jump-host access, considering operational safety constraints. But Timberline Foods is evaluating: An IoT data collector forwards telemetry to cloud endpoints using an unauthenticated plaintext protocol across an untrusted link. The necessary outcome is: The cloud receiver accepts authorized devices only and network inspection cannot read protected telemetry payloads.
A general office user cannot view restricted streams while approved operators retain necessary access. That observation would verify another scenario: A camera management platform exposes device inventory and live streams to any authenticated office user regardless of role. The corrective step for that other scenario is: Enforce per-device authorization, least-privilege roles and audit records for sensitive video access. But Timberline Foods is evaluating: An IoT data collector forwards telemetry to cloud endpoints using an unauthenticated plaintext protocol across an untrusted link. The necessary outcome is: The cloud receiver accepts authorized devices only and network inspection cannot read protected telemetry payloads.
