CI = ??
Confidentiality,
Integrity,
Availability.
There are other IT protection goals, including authenticity, privacy, reliability, and (non)repudiation.
These fall under integrity, confidentiality, availability, and integrity respectively! The CIA triad is pretty comprehensive!
Authenticity and non-repudiation falls under integrity.
Privacy falls under confidentiality.
Reliability in context is another word for availability.
