This policy setting determines which users can bypass file, directory, registry, and other persistent object permissions when restoring backed up files and directories on computers that run Windows Vista in your environment. This user right also determines which users can set valid security principals as object owners; it is similar to the Back up files and directories user right. When configuring a user right in the SCM enter a comma delimited list of accounts. Accounts can be either local or located in Active Directory, they can be groups, users, or computers. Vulnerability: An attacker with the Restore files and directories user right could restore sensitive data to a computer and overwrite data that is more recent, which could lead to loss of important data, data corruption, or a denial of service. Attackers could overwrite executable files that are used by legitimate administrators or system services with versions that include malicious software to grant themselves elevated privileges, compromise data, or install backdoors for continued access to the computer. Note Even if the following countermeasure is configured, an attacker could still restore data to a computer in a domain that is controlled by the attacker. Therefore, it is critical that organizations carefully protect the media that are used to back up data. Counter Measure: Ensure that only the local Administrators group is assigned the Restore files and directories user right, unless your organization has clearly defined roles for backup and for restore personnel. Potential Impact: If you remove the Restore files and directories user right from the Backup Operators group and other accounts you could make it impossible for users who have been delegated specific tasks to perform those tasks. You should verify that this change won't negatively affect the ability of your organization's personnel to do their jobs. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Restore files and directories (2) REG: NO INFO
