According to the CIA triad, which scenario exemplifies ensuring data integrity?

The CIA triad is a fundamental concept in information security that consists of three core principles: confidentiality, integrity, and availability. When focusing on data integrity, it refers to the assurance that data is accurate, consistent, and has not been altered or tampered with in an unauthorized manner.

In this context, ensuring data integrity involves confirming that the data remains correct and trustworthy throughout its lifecycle. Secure data transfer, as mentioned in one of the scenarios, plays a crucial role in maintaining integrity. When logistics data is securely transferred, it minimizes the risk of interception or unauthorized modifications, thus ensuring that the data received at the destination matches what was sent.

Limiting access to authorized personnel also directly supports data integrity. When only designated individuals have access to the data, there is a reduced chance of unauthorized alterations. By controlling who can modify the data, organizations can uphold its accuracy and reliability.

Therefore, both secure data transfer and access controls work synergistically to maintain the integrity of data, making the combination of these actions the most effective representation of ensuring data integrity according to the CIA triad.
