Ensure Internet Gateways are attached only to required VPCs

Internet Gateways should only be attached to VPCs that require direct internet access. Internal-only VPCs should not have internet gateways.

Security Impact

Unnecessary internet gateways create potential paths for internet exposure if routing is misconfigured.

How to Remediate

Review and detach internet gateways from VPCs that do not require direct internet access. Use VPC endpoints for AWS services.
