A. B. C. D.A.
During the data-in-use state, the information has already been accessed from storage and transmitted to the service, so reliance on a technology such as digital signatures is imperative to ensure security and complement the security methods used during previous states.
Data in transit relies on technologies such as TLS to encrypt network transmission of packets for security.
Data at rest primarily uses encryption for stored file objects.
Archived data would be the same as data at rest.
Digital signatures are used to verify the authenticity, integrity, and non-repudiation of a digital document or message. They provide a high level of security for data by adding an electronic signature to the data, which can be verified by the recipient to ensure that the data has not been tampered with during transmission or storage.
The use of digital signatures is most commonly associated with data in transit and data at rest. Data in transit refers to data that is being transmitted between two or more systems or networks, such as email messages or file transfers. Digital signatures can be used to ensure that the data has not been intercepted or altered during transmission, providing a high level of security for sensitive or confidential information.
Data at rest refers to data that is stored on a device or system, such as a hard drive, flash drive, or server. Digital signatures can be used to protect this data by adding an electronic signature to the data, which can be verified by the recipient to ensure that the data has not been tampered with while at rest.
Archived data, on the other hand, refers to data that has been stored for long-term retention, typically in a backup or archival system. While digital signatures can be used to protect archived data, it is less likely that they would be used in this context, as the data is typically not accessed or modified once it has been archived.
Therefore, the most likely data state to use digital signatures as a security protection mechanism would be data in transit or data at rest. The correct answer is either A or D, depending on the specific context of the question.
