Question

Aside from the fact that the cloud customer probably cannot locate/reach the physical storage assets of the cloud provider, and that wiping an entire storage space would impact other customers, why would degaussing probably not be an effective means of secure sanitization in the cloud?

Options

  • AAll the data storage space in the cloud is already gaussed.
  • BCloud data storage may not be affected by degaussing.
  • CFederal law prohibits it in the United States.
  • DThe blast radius is too wide.

Why each option

Degaussing is likely ineffective for secure sanitization in cloud environments because many modern cloud storage technologies are not susceptible to magnetic fields.

AAll the data storage space in the cloud is already gaussed.

The statement "All the data storage space in the cloud is already gaussed" is technically nonsensical; "gaussed" is not a standard term for storage state.

BCloud data storage may not be affected by degaussing.Correct

Degaussing relies on strong magnetic fields to scramble data on magnetic media like HDDs. Cloud storage often utilizes solid-state drives (SSDs) or object storage, which store data electrically or through other non-magnetic means and are therefore immune to degaussing.

CFederal law prohibits it in the United States.

There is no federal law broadly prohibiting degaussing in the cloud; instead, the technical ineffectiveness is the primary issue.

DThe blast radius is too wide.

While a wide 'blast radius' is a potential concern, the question specifically asks why degaussing would not be an *effective means of secure sanitization* from a technical standpoint.
