Vulnerability discussion

Backup Operators are able to read and write to any file in the system, regardless of the rights assigned to it. Backup and restore rights permit users to circumvent the file access restrictions present on NTFS disk drives for backup and restore purposes. Members of the Backup Operators group must have separate logon accounts for performing backup duties.

Check content

Run "Computer Management". Navigate to System Tools >> Local Users and Groups >> Groups. Review the members of the Backup Operators group. If the group contains no accounts, this is not a finding. If the group contains any accounts, the accounts must be specifically for backup functions. If the group contains any standard user accounts used for performing normal user tasks, this is a finding.

Fix text

Create separate accounts for backup operations for users with this privilege.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
