AWS CloudHSM and VPC endpoints
You can establish a private connection between your VPC and AWS CloudHSM by creating an
interface VPC endpoint. Interface endpoints are powered by AWS PrivateLink
Each interface endpoint is represented by one or more Elastic Network Interfaces in your subnets.
For more information, see Interface VPC endpoints (AWS PrivateLink) in the Amazon VPC User Guide.
Considerations for AWS CloudHSM VPC endpoints
Before you set up an interface VPC endpoint for AWS CloudHSM, ensure that you review Interface endpoint properties and limitations in the Amazon VPC User Guide.

AWS CloudHSM supports making calls to all of its API actions from your VPC.
Creating an interface VPC endpoint for AWS CloudHSM
You can create a VPC endpoint for the AWS CloudHSM service using either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). For more information, see Creating an interface endpoint in the Amazon VPC User Guide.
To create a VPC endpoint for AWS CloudHSM, use the following service name:
com.amazonaws.
region
.cloudhsmv2
For example, in the US West (Oregon) Region (us-west-2
), the service name
would be:
com.amazonaws.us-west-2.cloudhsmv2
To make it easier to use the VPC endpoint, you can enable a private DNS hostname for
your VPC endpoint. If you select the Enable Private DNS Name option, the
standard AWS CloudHSM DNS hostname
(https://cloudhsmv2.
) resolves
to your VPC endpoint.<region>
.amazonaws.com
This option makes it easier to use the VPC endpoint. The AWS SDKs and AWS CLI use the standard AWS CloudHSM DNS hostname by default, so you do not need to specify the VPC endpoint URL in applications and commands.
For more information, see Accessing a service through an interface endpoint in the Amazon VPC User Guide.
Creating a VPC endpoint policy for AWS CloudHSM
You can attach an endpoint policy to your VPC endpoint that controls access to AWS CloudHSM. The policy specifies the following information:
-
The principal that can perform actions.
-
The actions that can be performed.
-
The resources on which actions can be performed.
For more information, see Controlling access to services with VPC endpoints in the Amazon VPC User Guide.
Example: VPC endpoint policy for AWS CloudHSM actions
The following is an example of an endpoint policy for AWS CloudHSM. When attached to an endpoint, this policy grants access to the listed AWS CloudHSM actions for all principals on all resources. See Identity and access management for AWS CloudHSM for other AWS CloudHSM actions and their corresponding IAM permissions.
{ "Statement":[ { "Principal":"*", "Effect":"Allow", "Action":[ "
