This security policy reference topic for the IT professional describes the best practices, location, values, policy management, and security considerations for this policy setting.

Reference

This policy setting determines which users can perform volume or disk management tasks, such as defragmenting an existing volume, creating or removing volumes, and running the Disk Cleanup tool.

Use caution when assigning this user right. Users with this user right can explore disks and extend files in to memory that contains other data. When the extended files are opened, the user might be able to read and modify the acquired data.

This policy setting is supported on versions of Windows that are designated in the Applies To list at the beginning of this topic.

Constant: SeManageVolumePrivilege

Possible values

  • User-defined list of accounts

  • Not Defined

Best practices

  1. Ensure that only the local Administrators group is assigned the Perform volume maintenance tasks user right.

Location

Operating system version differences

There are no differences in the way this policy setting works between the supported versions of Windows that are designated in the Applies To list at the beginning of this topic.

Policy management

This section describes features, tools, and guidance to help you manage this policy.

A restart of the computer is not required for this policy setting to be effective.

Any change to the user rights assignment for an account becomes effective the next time the owner of the account logs on.

Group Policy

Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:

  1. Local policy settings

  2. Site policy settings

  3. Domain policy settings

  4. OU policy settings

When a local setting is greyed out, it indicates that a GPO currently controls that setting.

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

Vulnerability

A user who is assigned the Perform volume maintenance tasks user right could delete a volume, which could result in the loss of data or a denial-of- service condition. Also, disk maintenance tasks can be used to modify data on the disk, such as user rights assignments that might lead to escalation of privileges.

Countermeasure

Ensure that only the local Administrators group is assigned the Perform volume maintenance tasks user right.

Potential impact

None. Restricting the Perform volume maintenance tasks user right to the local Administrators group is the default configuration.
