| Rule | ACM certificates should be set to expire within 30 days |
| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ Medium |
Rule Description:
According to the Federal Financial Institutions Examination Council (FFIEC) regulations, all ACM (Amazon Certificate Manager) certificates should be set to expire within 30 days for compliance purposes. This rule ensures that certificates issued by ACM for federal financial institutions meet the required security standards and are regularly renewed to prevent any potential security vulnerabilities.
Troubleshooting Steps:
If you encounter any issues or violations regarding ACM certificates expiration for FFIEC compliance, follow these troubleshooting steps:
- 1.
Verify the expiration date of the ACM certificates:
- Go to the AWS Management Console and navigate to the ACM service.
- Locate the certificate in question and check the expiration date assigned to it.
- Ensure that the expiration date is set within 30 days from the current date.
- 2.
Check the FFIEC compliance requirements:
- Review the FFIEC guidelines and confirm that certificates must expire within 30 days.
- Ensure that there have been no recent changes or updates to the regulations that might affect the expiration requirements.
- 3.
Ensure the certificate auto-renewal is enabled:
- Check the ACM certificate settings and verify that the auto-renewal feature is enabled.
- Auto-renewal ensures that certificates are automatically renewed before they expire, thus avoiding potential compliance issues.
- 4.
Validate the certificate deployment and usage:
- Confirm that the ACM certificate is correctly deployed and being utilized in the relevant applications, websites, or services.
- Check for any misconfigurations or outdated references to old certificates that could lead to non-compliance.
- 5.
Contact AWS Support:
- If you cannot identify any issues or if you require further assistance, it is recommended to contact AWS Support for guidance and troubleshooting.
Necessary Code:
No specific code is required for this policy. However, the following AWS CLI command can be used to list all ACM certificates and their details:
aws acm list-certificates
This command will provide a list of all ACM certificates associated with your account, including their ARNs, domain names, and expiration dates. It can be helpful to identify certificates that need to be updated to comply with the FFIEC regulations.
Remediation Steps:
To remediate the issue and ensure compliance with FFIEC regulations regarding ACM certificates expiration:
- 1.
Identify certificates that are not set to expire within 30 days:
- Use the AWS CLI command mentioned above to list all ACM certificates.
- Filter the results based on the expiration date and identify the certificates that exceed the 30-day threshold.
- 2.
Update the expiration date for non-compliant certificates:
- Select each non-compliant certificate and modify its expiration date accordingly.
- Set the new expiration date to a value within the 30-day range.
- 3.
Enable auto-renewal for ACM certificates:
- For each certificate, enable the auto-renewal feature to ensure future compliance.
- This feature will automatically renew the certificate before it expires, reducing the risk of non-compliance.
- 4.
Validate the changes:
- Verify that the certificates now have the correct expiration date set within the 30-day range.
- Double-check the auto-renewal status to ensure it is correctly enabled for all applicable certificates.
- 5.
Retest compliance:
- Monitor the ACM certificates periodically to ensure ongoing compliance with the FFIEC regulations.
- Implement a process to review and update certificate expiration dates within the required time frame.
Remember to regularly review and update ACM certificates to maintain compliance with FFIEC regulations and ensure the security of your federal financial institution's infrastructure.
