Which part of the CIA Triad was preserved when data was restored from a backup after a power surge?

  1. Confidentiality

  2. Integrity

  3. Availability

  4. Accountability

The correct answer is: Availability

When data is restored from a backup after a power surge, the aspect of the CIA Triad that is preserved is availability. The CIA Triad consists of three core principles: confidentiality, integrity, and availability. Availability refers to the accessibility of data and resources when needed. In the context of restoring data from a backup, this action ensures that the data and systems are accessible again after an unexpected event, such as a power surge that may have caused data loss or system downtime. By restoring from a backup, organizations can ensure that users can access the information necessary for normal operations. While restoring from a backup may also have implications for confidentiality and integrity, the question specifically pertains to how the restoration process impacts the availability of data. For instance, if the backup was current and correctly managed, the data should be readily available once restored. Hence, the significance of availability in this context is paramount.
