Why each option
The CIA triad is the foundational model of information security, standing for Confidentiality, Integrity, and Availability.
Confidentiality ensures information is accessible only to authorized parties. Integrity ensures data is accurate and unaltered. Availability ensures systems and data are accessible when needed. Together these three properties define the core objectives of any information security program.
'Identity' is not a component of the CIA triad; Integrity is the correct second term.
'Authorization' is not a component of the CIA triad; Availability is the correct third term.
Both 'Identity' and 'Authorization' are substituted incorrectly for Integrity and Availability.
