Which two terms relate to data protection: protecting data contents and ensuring it hasn't been tampered with?

The correct choice is based on the foundational principles of data protection. Integrity refers to the accuracy and consistency of data over its lifecycle, which ensures that the data has not been altered or tampered with. This is essential in maintaining trust in the data being used for decision-making, as any unauthorized modifications can lead to serious consequences.

Confidentiality, on the other hand, deals with protecting sensitive information from unauthorized access, ensuring that only authorized users have access to it. Although confidentiality focuses on who can see or access the data, it is closely tied to maintaining the overall security posture of the data.

When considering the two aspects mentioned in the question—protecting data contents and ensuring it hasn't been tampered with—integrity and confidentiality are the most relevant terms. These principles help create a secure environment for data, ensuring it not only remains protected from unauthorized access but also retains its true and original form without unauthorized alterations.

Other options either mix terms that pertain to different aspects of data management, like availability—which relates to data being accessible when needed—and scalability, which relates to the flexibility of the infrastructure supporting the data. Therefore, integrity and confidentiality specifically address the considerations in the question.
