I didn't know either, so I looked it up: The three initials stand for the three most important IT protection goals, often referred to as the "pillars of data security":

Confidentiality,

Integrity,

Availability.

There are other IT protection goals, including authenticity, privacy, reliability, and (non)repudiation.

>authenticity, privacy, reliability, and (non)repudiation.

These fall under integrity, confidentiality, availability, and integrity respectively! The CIA triad is pretty comprehensive!

I think CIA covers everything in the list, right?

Authenticity and non-repudiation falls under integrity.

Privacy falls under confidentiality.

Reliability in context is another word for availability.
