Cevap

Confidentiality is the pillar directly upheld by full-disk encryption because it prevents unauthorized exposure of stored information.
Full-disk encryption maintains confidentiality by rendering stored data unreadable to anyone who does not possess the decryption credentials, protecting sensitive information from disclosure if a physical device is lost or compromised.

Adım Adım Çözüm

1
Identify the primary function of the security control described in the scenario.
Full-disk encryption scrambles stored data so that it cannot be read without authenticating with a valid decryption key.
This protection prevents unauthorized parties from inspecting sensitive files on stolen or lost hardware.
2
Map this function to the corresponding pillar of the CIA triad.
Protecting data from unauthorized disclosure is the definition of Confidentiality.
Confidentiality focuses on privacy and restricting data access solely to authorized entities.
