What is required to prevent unauthorized changes to stored information?

• A. Server updates
• B. Data integrity
• C. User training
• D. Access logs

Answer: (B)

Data integrity is essential for preventing unauthorized changes to stored information as it ensures that the data remains accurate, consistent, and trustworthy throughout its lifecycle. Maintaining data integrity involves implementing controls and mechanisms that verify that data is not tampered with or altered by unauthorized users. This can include checksums, hash functions, and various encryption methods that can detect and prevent unauthorized modifications.

By safeguarding data integrity, organizations can ensure that the information used for decision-making and operational functions is reliable, thereby reducing the risk of errors that could arise from corrupt or compromised data.

While server updates, user training, and access logs can contribute to overall security policies and practices, they do not directly address the core issue of maintaining the accuracy and consistency of stored information in the way that data integrity does. Server updates can improve system performance and patch vulnerabilities, user training can raise awareness about security practices, and access logs help monitor user activity, but they do not inherently prevent unauthorized changes to the data itself.
