In the standard introductory client–cloud model, loss of the Internet…

Concept

Cloud computing provides on-demand network access to a shared pool of configurable computing resources. Its availability and security depend on connectivity, architecture, configuration, and operating controls; neither is an unconditional property.

Application

• “Cloud computing is Internet-based computing where shared resources, software, and information are provided to firms on demand” describes network access, resource pooling, and on-demand service.

• “Cloud computing can easily host enterprise system applications” is consistent with cloud infrastructure and platform services that run organizational applications.

• “If the internet connection goes down, then the cloud system will not function” expresses the introductory client-access limitation: loss of connectivity interrupts access to remote cloud services from the affected client.

• “Data stored in a cloud computing system is always secure” makes an absolute guarantee. Cloud providers and customers must manage identities, permissions, encryption, configuration, monitoring, and other controls, so cloud storage is not automatically secure in every circumstance.

Cross-check

The NIST cloud definition identifies broad network access, on-demand service, and resource pooling as core characteristics, while NIST security guidance treats cloud security as a set of risks and controls to manage. Therefore, the absolute word “always” is the decisive flaw.

Result

The false statement is “Data stored in a cloud computing system is always secure.”
