Vulnerability discussion

Removable hard drives can be formatted and ejected by others who are not members of the Administrators Group, if they are not properly configured. Formatting and ejecting removable NTFS media should only be done by administrators.

Check content

Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for “Devices: Allowed to Format and Eject Removable Media” is not set to “Administrators”, then this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Microsoft\Windows NT\CurrentVersion\Winlogon Value Name: AllocateDASD Value Type: REG_SZ Value: 0

Fix text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “Devices: Allowed to Format and Eject Removable Media” to “Administrators”.
