EC2 Network ACL Should Have Subnet IDs

Source Sentinel Policy

ec2-network-acl-should-have-subnet-ids.sentinel

Conversion Quality

Limited

Why this is limited

The Sentinel policy uses tfconfig/v2, reference metadata, and module-aware address reconstruction to determine whether a network ACL is connected through aws_network_acl_association. Current tfpolicy guidance does not expose equivalent reference metadata, so an exact translation is not possible.

What the approximation does

The tfpolicy version checks either:

  • subnet_ids is present directly on the network ACL, or
  • a matching aws_network_acl_association can be found via core::getresources() and a value-based lookup

Limitations encountered

  • This is value matching, not true Terraform graph reasoning
  • It may behave differently for newly created resources with unresolved values
  • It does not reproduce the Sentinel policy's module-aware reference reconstruction exactly
