How should data integrity be ensured in investigations and security records?

• A. Secure storage, robust access controls, audit logs, and immutable records.
• B. Publicly sharing all records to encourage transparency.
• C. Relying on single-user access without logs.
• D. Storing data only on local devices without backups.

Answer: (A)

Maintaining data integrity in investigations and security records hinges on preventing tampering and ensuring traceability. Secure storage protects data from unauthorized modification and environmental threats. Robust access controls enforce who can view or edit records, using least privilege and strong authentication to reduce the chance of improper changes. Audit logs provide a verifiable trail of actions—who accessed or altered records, when, and what was done—creating accountability. Immutable records, such as tamper-evident or write-once storage, make it extremely difficult to alter information after creation, supporting long-term trust and non-repudiation.

Together, these practices keep evidence trustworthy, verifiable, and resilient over time. Public sharing all records would compromise confidentiality and integrity; relying on a single user with no logs eliminates accountability and increases risk of manipulation; storing only on local devices without backups risks loss and untracked changes.
