In Microsoft’s SCI learning content, the core objective of protecting information is framed by the CIA triad. Microsoft explains that “confidentiality, integrity, and availability are foundational security principles.” Within this model, integrity is described as the assurance that information remains trustworthy and unchanged from its intended state. The SCI materials state that integrity means “preventing unauthorized modification and ensuring the accuracy and completeness of data.” When a requirement says, “ensuring that the data you retrieve is the same as the data you stored,” it directly maps to this integrity principle—verifying that data hasn’t been altered, corrupted, or tampered with during storage or transmission.

Microsoft’s guidance further highlights that integrity is supported by controls that “detect or prevent unauthorized changes,” including cryptographic hashes, checksums, and digital signatures that can “provide proof that content hasn’t been modified.” By contrast, confidentiality focuses on restricting access (for example, through least privilege and encryption), and availability focuses on “reliable and timely access to information and systems.” Because the scenario emphasizes that the retrieved data is identical to the stored data, it is not about access or uptime but about preserving correctness and detecting alteration—which is precisely the integrity objective in Microsoft’s Security, Compliance, and Identity guidance.
