Control Requirement 5.6.2.8: Ensuring Integrity of Backup and Restoration Processes
Ensuring the integrity of backup and restoration processes is paramount. Control requirement 5.6.2.8 from the CAN/DGSI 104:2021 Rev 1 2024 standard emphasizes the necessity of using a sampling of backup data to test and verify recovery procedures at regular intervals. This practice is crucial for maintaining the reliability and security of an organization’s data.
The Importance of Regular Testing and Verification
Regular testing and verification of backup data serve several critical purposes:
Validation of Recovery Procedures: Ensuring that recovery procedures are effective and can restore data accurately and efficiently.
Detection of Issues: Identifying any discrepancies or issues in the backup and restoration process before they become critical problems.
Security Assurance: Confirming that backup data is secure and has not been compromised by unauthorized access or cyber threats.
Compliance: Meeting regulatory requirements and internal policies to avoid penalties and ensure business continuity.
Implementing Sampling and Testing Procedures
To effectively implement sampling and testing of backup data, organizations should follow a structured approach:
Selection of Sample Data: Choose a representative sample of backup data that includes critical and non-critical data. This ensures a comprehensive test of the recovery procedures.
Execution of Recovery Procedures: Perform the recovery process using the selected sample data in a controlled environment. Ensure that the restored data matches the original data.
Verification of Integrity: Check the integrity of the restored data by comparing it with the original data. Look for any discrepancies or signs of unauthorized access.
Documentation and Review: Record the results of the testing and verification process. Regularly review and update the procedures to adapt to changing threats and technologies.
Policy and Enforcement
Organizations must have a clear policy outlining the requirements for sampling and testing backup data. This policy should include:
Frequency: Sampling and testing must be conducted at regular intervals, such as monthly or quarterly, depending on the organization’s needs.
Procedure: A detailed guide for selecting sample data, executing recovery procedures, and verifying data integrity.
Enforcement: Consequences for failing to adhere to the policy, which may include disciplinary action.
Conclusion
Regularly testing and verifying backup data using a sampling approach is a vital control requirement from the CAN/DGSI 104:2021 Rev 1 2024 standard that ensures the integrity of an organization’s backup and restoration processes. By following a structured procedure and adhering to a clear policy, organizations can safeguard their valuable data and maintain business continuity. Contact us today to get certified!
