| Cloud | AWS |
| Category | EC2 |
| Description | Ensures communication between public and private VPC tiers is not enabled |
| More Info | Communication between the public tier of one VPC and the private tier of other VPCs should never be allowed. Instead, VPC peerings with proper NACLs and gateways should be used |

| Recommended Action | Remove the NACL rules allowing communication between the public and private tiers of different VPCs |
