VPC interface endpoints should be enabled for Systems Manager
Description
This control checks whether VPC interface endpoints are enabled for AWS Systems Manager (SSM). The control fails if there is no VPC interface endpoint for SSM or if the endpoint is not available. VPC interface endpoints allow you to privately connect your VPC to supported AWS services without requiring an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. This helps improve security by keeping traffic within the AWS network and reducing exposure to the public internet.
Remediation
Create a VPC interface endpoint for Systems Manager to enable private connectivity to AWS SSM.
