Rule: API Gateway Stage Should Use SSL Certificate
This rule ensures that API Gateway stages use SSL certificates for secure communication.
| Rule | API Gateway stage should uses SSL certificate |
| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ Medium |
Rule Description:
API Gateway stages should use SSL certificates that comply with the Federal Financial Institutions Examination Council (FFIEC) requirements. The FFIEC is an interagency body that prescribes uniform principles, standards, and report forms for the federal examination of financial institutions. This rule ensures that sensitive financial data transmitted through API Gateway is secured with a reliable SSL certificate, meeting the regulatory guidelines set by the FFIEC.
Troubleshooting Steps (if applicable):
If the API Gateway stage does not have an SSL certificate that complies with FFIEC requirements, it can lead to non-compliance issues, vulnerabilities, and potential data breaches. Here are the troubleshooting steps to adhere to this rule:
- 1.
Check Current SSL Certificate: Verify the existing SSL certificate for the API Gateway stage and ensure that it meets the FFIEC compliance criteria.
- 2.
Obtain FFIEC-compliant SSL Certificate: If the current SSL certificate does not comply with FFIEC requirements, obtain an SSL certificate that adheres to the standards set by FFIEC.
- 3.
Configure SSL Certificate in API Gateway: Once you have obtained a valid FFIEC-compliant SSL certificate, follow the steps below to configure it in the API Gateway:
a. Log in to the API Gateway console or use the AWS CLI/API. b. Navigate to the API Gateway service and select the desired stage. c. In the stage settings, locate the SSL Certificate configuration section. d. Choose the option to update the SSL certificate. e. Provide the necessary details, such as the SSL certificate ARN (Amazon Resource Name) and any other required information. f. Save the changes to apply the FFIEC-compliant SSL certificate to the API Gateway stage.
- 4.
Validate SSL Certificate Configuration: After configuring the SSL certificate, it is crucial to validate the setup to ensure proper functionality and compliance. Use the following steps:
a. Invoke an API endpoint from a client application or utilize a testing tool (e.g., cURL, Postman) to send a request to the API Gateway stage. b. Verify the response received includes a valid SSL certificate and does not display any security warnings or errors. c. Monitor the API Gateway logs and metrics to confirm that SSL communication is successfully established with the FFIEC-compliant SSL certificate.
Necessary Codes (if applicable):
Depending on your specific use case and programming language, you may need to write or modify code to configure the SSL certificate compliant with FFIEC requirements. Here is a sample code snippet using the AWS CLI to update the SSL certificate for the API Gateway stage:
aws apigateway update-stage \ --rest-api-id <API ID> \ --stage-name <Stage Name> \ --patch-operations op=replace,path=/clientCertificateId,value=<SSL Certificate ID>
Replace
<API ID><Stage Name><SSL Certificate ID>Note: This is just an example. Please refer to the AWS API Gateway documentation for the specific commands and code needed based on your AWS environment and programming language.
Step-by-Step Guide for Remediation:
Follow these steps to ensure your API Gateway stage uses an SSL certificate compliant with FFIEC requirements:
- 1.
Check the current SSL certificate configuration for the API Gateway stage and verify if it complies with FFIEC regulations.
- 2.
If the SSL certificate does not comply, obtain an SSL certificate that meets the FFIEC compliance criteria. Consult with your organization's security team or a trusted SSL certificate provider for assistance.
- 3.
Configure the FFIEC-compliant SSL certificate in the API Gateway by either using the AWS Management Console or AWS CLI/API.
- 4.
To configure via the AWS Management Console: a. Log in to the AWS Management Console. b. Navigate to the Amazon API Gateway service. c. Select the desired API Gateway. d. Locate the desired stage and click on its name to access the stage settings. e. In the SSL Certificate settings section, choose the option to update the SSL certificate. f. Provide the required details, including the SSL certificate ARN. g. Save the changes to apply the FFIEC-compliant SSL certificate to the API Gateway stage.
- 5.
To configure using the AWS CLI: a. Install and configure the AWS CLI if you haven't already. b. Open your preferred command-line interface. c. Execute the appropriate AWS CLI command to update the SSL certificate. Refer to the necessary code section above for a sample CLI command. d. Make sure to replace the placeholders in the command with actual values specific to your API and SSL certificate.
- 6.
After configuring the SSL certificate, validate the setup by invoking an API endpoint, ensuring that it successfully establishes SSL communication and doesn't display any security warnings or errors.
- 7.
Monitor the API Gateway logs and metrics to confirm the successful utilization of the FFIEC-compliant SSL certificate.
By following these steps, you can ensure that your API Gateway stage satisfies the SSL certificate requirement set by the Federal Financial Institutions Examination Council (FFIEC), providing a secure channel for financial data transmission.
