| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ High |
Rule Description:
According to the Federal Financial Institutions Examination Council (FFIEC) requirements, all EC2 instances used by financial institutions must be placed within a Virtual Private Cloud (VPC) for enhanced security and compliance.
Troubleshooting Steps:
- 1.Access the AWS Management Console.
- 2.Navigate to the EC2 service.
- 3.Identify the EC2 instances that are not currently placed within a VPC.
- 4.Note down the instance IDs for later reference.
Necessary Codes:
No specific codes are required for this rule.
Remediation Steps:
- 1.
Access the AWS Management Console.
- 2.
Navigate to the EC2 service.
- 3.
Identify the EC2 instances that need to be placed within a VPC.
- 4.
For each instance identified:
a. Stop the instance if it is running. b. Note down any important configurations and data associated with the instance, as they may be lost during the upcoming steps. c. Create a new VPC if not already available or select an existing VPC to place the instance. d. Launch a new instance within the chosen VPC, ensuring to select appropriate instance type, security groups, and storage options. e. Configure the newly launched instance with the necessary settings required for your application.
- 5.
Validate the functionality and accessibility of the converted instance within the VPC.
- 6.
If successful, terminate the old instance that was not placed within a VPC.
- 7.
Update any dependencies on the old instance to point to the new instance within the VPC.
- 8.
Consider enabling additional security measures within the VPC, such as Network Access Control Lists (NACLs) and Security Groups, to further enhance the security and compliance of the EC2 instances.
Note: It is recommended to review the FFIEC guidelines and consult with a compliance expert to ensure all necessary measures are taken to meet the specific requirements of your financial institution.
