Step-by-step Guide for Remediation
To ensure VPC internet gateways are attached to authorized VPCs in compliance with the NIST Cybersecurity Framework (CSF) v1, follow these steps:
- 1.
Identify the authorized VPC: Determine the VPC that is authorized and compliant with NIST CSF v1. This VPC should have all the necessary security controls and configurations in place.
- 2.
Configure the internet gateway: Go to the AWS Management Console and navigate to the VPC service.
- 3.
Create an internet gateway: If an internet gateway is not already created, create one by clicking on "Create internet gateway" and follow the on-screen instructions. Ensure that the internet gateway is associated with the correct AWS account and region.
- 4.
Attach the internet gateway to the authorized VPC: Select the internet gateway and click on the "Attach to VPC" button. Choose the authorized VPC from the list provided.
- 5.
Confirm attachment: Review the confirmations and ensure that the internet gateway is successfully attached to the authorized VPC.
- 6.
Verify connectivity: Test the internet connectivity by launching an EC2 instance or accessing resources within the authorized VPC. Check if you can access the internet from the VPC and if incoming traffic is properly monitored within the authorized environment.
- 7.
Monitor and audit: Regularly monitor and audit the internet gateway attachment to ensure continued compliance with the NIST CSF v1.
Conclusion
By strictly adhering to the rule and ensuring that VPC internet gateways are only attached to authorized VPCs, you can greatly enhance the security and compliance of your network infrastructure. Regularly verify the attachment and be proactive in monitoring and auditing to maintain a secure environment.
