Which property ensures that only the intended recipient can access the data and nobody else?

A.
Confidentiality

B.
Capability

C.
Integrity

D.
Availability

Explanation:
Confidentiality is the assurance that information is not disclosed to unauthorized individuals, programs, or
processes. Some information is more sensitive than other information and requires a higher level of
confidentiality.
Confidentiality ensures that the necessary level of secrecy is enforced at each junction of data processing and
prevents unauthorized disclosure. This level of confidentiality should prevail while data resides on systems and
devices within the network, as it is transmitted, and once it reaches its destination.
Incorrect Answers:
B: Capability is not what ensures that only the intended recipient can access the data and nobody else.
C: Integrity ensures that data is unaltered. This is not what is described in the question.
D: Availability ensures reliability and timely access to data and resources to authorized individuals. This is not
what is described in the question.
