Which practices support data integrity in spin operation logs?

• A. Use unsynchronized timestamps and unrestricted access.
• B. Use time-stamped entries, controlled access, and regular backups.
• C. Delete old entries after a week.
• D. Store logs only on local machine without backups.

Answer: (B)

Ensuring data integrity in spin operation logs comes from creating a trustworthy, verifiable record of events. Time-stamped entries provide a precise timeline for every event, making it possible to verify the order of operations and detect any tampering. When each log entry has a reliable timestamp, you can trace exactly what happened and when, which is essential for integrity and auditing. Controlled access means only authorized people or processes can write or modify logs. This limits the chance of intentional or accidental alterations, preserves accountability, and supports non-repudiation because actions can be tied to specific users or roles. Regular backups add resilience and verifiability. By keeping secure, regular copies of logs, you can recover from data loss and compare current logs to backups to spot discrepancies or tampering. Backups also enable integrity checks over time and across systems. Why the other options don’t fit: unsynchronized timestamps make it hard to determine the correct sequence of events and can mask tampering. Unrestricted access opens the door to unauthorized changes that compromise the log’s trustworthiness. Deleting old entries erases parts of the audit trail, making it impossible to reconstruct events. Storing logs only on a local machine without backups creates a single point of failure and removes external verification, increasing the risk of loss or tampering without detection. Together, time stamps, controlled access, and regular backups establish a dependable, auditable, and recoverable log system.
