What is the most appropriate description for the term 'confidentiality' ?

  • A.A set of rules to limit access to data
  • B.Maintenance of and assurance of the accuracy and consistency of data over its entire life-cycle
  • C.A guarantee of reliable access to the data by authorized people
  • D.The process or action of verifying the identity of a user or process

Answer: A

Confidentiality is best described as a set of rules to limit access to data.

Confidentiality, the first part of the CIA triad, means information is disclosed only to those authorised to see it, enforced through access controls, encryption and similar rules.

The other options describe the rest of the triad and a related idea. Assuring the accuracy and consistency of data over its life-cycle is integrity. Reliable access to data by authorised people is availability. Verifying the identity of a user or process is authentication.
