Virtual machines must remove unnecessary AHCI devices

中レベル 1手動レビューvmware

説明

Removing unnecessary devices from virtual machines minimizes the attack surface and reduces potential pathways for data exfiltration or unauthorized data capture. This practice aligns with the principle of least functionality, ensuring that VMs have only the essential components required to perform their designated functions. Manual review: the check needs vCenter/PowerCLI, firmware or guest access, or an organization-specific value.

Inspect VM hardware for unnecessary SATA/AHCI controllers. With PowerCLI/Get-View, review virtual devices and identify VirtualAHCIController devices that do not back a required virtual disk or CD/DVD device.

修正方法

修正方法: ガイダンスまたは IaC パッチ

To remediate this recommendation, power off the VM if required and remove unused AHCI/SATA controllers only after removing or moving dependent devices. Do not remove a controller that is actively backing a required virtual disk.
