What are the three main aspects of information security?

Show Suggested Answer Hide Answer
Suggested Answer: B

The three fundamental properties of information security are confidentiality, integrity, and availability, often referred to as the CIA triad. Confidentiality means information is accessible only to authorized persons or entities. Integrity means safeguarding the accuracy and completeness of information. Availability means information and associated assets are accessible and usable when required. These principles are foundational within ISO/IEC 27001 and ISO/IEC 27002. Therefore, option B is correct.

I keep mixing up the terms. I remember non-repudiation and authenticity from another topic, but I don't think they fit here.

I thought it was A at first, but now I’m leaning towards B. The terms seem to match what we discussed in class.

I'm not entirely sure, but I feel like recoverability might be important too. Wasn't there a question about that in our practice tests?

I think the answer is B. I remember studying about the CIA triad, which stands for confidentiality, integrity, and availability.
