Control Requirement 5.6.2.7: Ensuring Security and Integrity of Critical Backups
Data is one of the most valuable assets for any organization. Ensuring the security and integrity of critical backups is not just a best practice but a necessity. Control requirement 5.6.2.7 from the CAN/DGSI 104:2021 Rev 1 2024 standard emphasizes the importance of regularly testing these backups to verify their reliability, accessibility, and uncompromised state.
Why Regular Testing of Critical Backups is Essential
Regular testing of critical backups is crucial for several reasons:
Reliability: Ensuring that backups can be restored successfully without any data loss or corruption.
Accessibility: Verifying that backups are accessible when needed, especially during emergencies.
Security: Confirming that backups are secure from unauthorized access and cyber threats.
Compliance: Meeting regulatory requirements and internal policies to avoid penalties and ensure business continuity.
Steps to Test Critical Backups
To effectively test critical backups, organizations should follow a structured procedure:
Planning: Define the scope and objectives of the backup testing. Identify the critical data and systems that need to be tested.
Execution: Perform the backup restoration process in a controlled environment. Ensure that the restored data matches the original data.
Verification: Check the integrity and security of the restored data. Look for any discrepancies or signs of unauthorized access.
Documentation: Record the results of the backup testing. Provide evidence of successful restoration and any issues encountered.
Review: Regularly review and update the backup testing procedures to adapt to changing threats and technologies.
Policy and Enforcement
Organizations must have a clear policy outlining the requirements for testing critical backups. This policy should include:
Frequency: Backups must be tested regularly as determined by the organization.
Procedure: A step-by-step guide for testing backups, including the restoration and comparison process.
Enforcement: Consequences for failing to adhere to the policy, which may include disciplinary action.
Conclusion
Regularly testing critical backups is a vital control requirement that ensures the security and integrity of an organization’s data. By following a structured procedure and adhering to a clear policy, organizations can safeguard their valuable data and maintain business continuity, as outlined in the CAN/DGSI 104:2021 Rev 1 2024 standard.
