aws_vpc_endpoints Resource

Use the aws_vpc_endpoints InSpec audit resource to test properties of some or all AWS VPC Endpoints.

VPC Endpoints can be of two types: ‘Gateway’ and ‘Interface’.

A Gateway type VPC endpoint accepts a route-table whereas an Interface type VPC endpoint takes one or more subnets and one or more security groups. Hence their properties might differ based on the type.

For additional information, including details on parameters and properties, see the AWS documentation on VPC Endpoints.
