Rule: Backup Recovery Points Should Be Encrypted
This rule states that backup recovery points must be encrypted for data security.
| Rule | Backup recovery points should be encrypted |
| Framework | NIST Cybersecurity Framework (CSF) v1.1 |
| Severity | ✔ Low |
Rule Description
The rule states that backup recovery points should be encrypted to align with the NIST Cybersecurity Framework (CSF) v1. Encrypting recovery points ensures the confidentiality and integrity of the data in case of a breach or unauthorized access.
Troubleshooting Steps
If backup recovery points are not encrypted as per the NIST Cybersecurity Framework (CSF) v1, the following troubleshooting steps can be taken:
- 1.
Check Current Encryption Settings: Verify if the existing backup recovery points are encrypted or not. This can be done by reviewing the backup configuration and encryption settings.
- 2.
Verify Compliance with NIST CSF v1: Confirm the specific encryption requirements outlined in the NIST CSF v1. Ensure that the encryption algorithm, key management, and data protection measures are in place as per the framework guidelines.
- 3.
Review Backup Solution Documentation: Check the documentation provided by the backup solution vendor. Look for specific instructions or best practices related to encrypting recovery points. It may provide useful information on how to enable encryption for existing or future backups.
- 4.
Ensure Encryption Key Security: Ensure that encryption keys used for backup recovery points are adequately secured. Keys should be stored separately from the backup data and protected using strong access controls.
- 5.
Test Data Restoration: Perform a test data restoration from an encrypted recovery point to validate that the encryption is working correctly. This step verifies that the encryption does not adversely affect the restoration process.
Necessary Codes
There are no specific codes provided for this rule. However, depending on the backup solution or platform used, encryption settings may be configurable through the backup software's administration console or command-line interface.
Step-by-Step Guide for Remediation
Follow these steps to ensure that backup recovery points are encrypted in compliance with the NIST Cybersecurity Framework (CSF) v1:
- 1.
Identify Backup Solution: Determine the backup solution or platform being used. This could be a cloud-based backup service, on-premises backup software, or a combination of both.
- 2.
Access Backup Configuration: Log in to the backup administration console or interface. If using command-line interface, access the terminal or command prompt with appropriate privileges.
- 3.
Locate Encryption Settings: Navigate to the backup settings or options related to encryption. Look for options such as "Encryption," "Security," or "Data Protection."
- 4.
Enable Encryption: Enable the encryption option. Select a strong encryption algorithm approved by the NIST CSF v1, which typically includes AES (Advanced Encryption Standard) 256-bit encryption or higher.
- 5.
Configure Key Management: Set up proper key management for the encryption process. Ensure that encryption keys are securely generated/stored and that there are clear policies for key rotation, storage, and access control.
- 6.
Review Backup Schedule: Verify the backup schedule and ensure that encryption is applied consistently to all recovery points generated as per the NIST CSF v1.
- 7.
Test Encryption: Perform a full backup after enabling encryption to ensure that all future recovery points are encrypted. Validate the backup process and check that the encryption is functioning as expected.
- 8.
Document Encryption Procedures: Document the encryption procedures for backup recovery points to maintain a record and facilitate future audits or assessments.
- 9.
Regularly Monitor and Review: Continuously monitor the backup system to ensure that encryption remains enabled and functioning correctly. Periodically review encryption settings to align with any updates or changes to the NIST CSF v1 requirements.
It is important to note that the exact steps may vary depending on the backup solution used. Therefore, referencing the specific documentation provided by the vendor or seeking assistance from their support team is recommended for accurate configuration.
