Ensure Transit Gateway route tables restrict traffic
Transit Gateway route tables should be configured to restrict traffic between VPCs based on security requirements.
Security Impact
Default routing allows all attached VPCs to communicate, which may violate network segmentation requirements.
How to Remediate
Create separate Transit Gateway route tables for different security zones. Associate VPCs with appropriate route tables.
