Rule: EFS File Systems Should Be in a Backup Plan
Ensure EFS file systems are included in the backup plan for System and Information integrity (SI) compliance.
| Rule | EFS file systems should be in a backup plan |
| Framework | NIST 800-53 Revision 5 |
| Severity | ✔ High |
Rule Description
According to the NIST 800-53 Revision 5 guidelines, it is recommended to include EFS (Elastic File System) file systems in the organization's backup plan. EFS is a scalable and fully managed file storage service provided by Amazon Web Services (AWS) that allows multiple Amazon EC2 instances to securely access shared data concurrently.
Including EFS file systems in the backup plan ensures the availability and protection of critical data stored in these file systems. It allows for the recovery of data in case of accidental deletion, hardware failure, or other unforeseen circumstances.
Troubleshooting Steps
No specific troubleshooting steps are associated with this rule. However, if any issues are encountered during the backup or recovery process, the following general troubleshooting steps can be followed:
- 1.Check the AWS Management Console or use the AWS CLI to verify the status of the EFS file system.
- 2.Ensure that the appropriate backup policies and configurations are in place.
- 3.Review the AWS CloudTrail logs for any relevant error messages or events.
- 4.Verify the permissions and access controls for the IAM users or roles involved in the backup and recovery process.
- 5.Contact AWS support if the issue persists or if further assistance is required.
Necessary Codes
There are no specific codes related to this rule. However, configuring backup policies and automating the backup process can be achieved using the AWS Command Line Interface (CLI) or SDKs like AWS SDK for Python (Boto3).
Step-by-Step Guide for Remediation
To include EFS file systems in the backup plan based on NIST 800-53 Revision 5 guidelines, you can follow these steps:
- 1.Identify the EFS file systems that need to be included in the backup plan.
- 2.Evaluate the backup requirements for each file system, such as the frequency of backups, retention periods, and backup destinations.
- 3.Determine the appropriate backup solution, whether it is a native AWS backup service like AWS Backup or a custom backup solution using AWS CLI or SDKs.
- 4.Configure the backup policies and schedules based on the identified requirements.
- 5.Implement automated backup scripts or workflows using AWS CLI or SDKs for consistent and reliable backups.
- 6.Test the backup and recovery processes periodically to ensure data integrity and availability.
- 7.Monitor the backup logs and review any backup-related notifications or alerts.
- 8.Regularly review and update the backup plan as changes occur in the organization's infrastructure or data storage requirements.
By following these steps, organizations can ensure that their EFS file systems are included in the backup plan as recommended by NIST 800-53 Revision 5. This helps safeguard critical data and supports the organization's overall data recovery strategy.
