Vulnerability discussion

Unattended systems are susceptible to unauthorized use and must be locked. Preventing users from changing the screen saver ensures an approved screen saver is used. This protects critical and sensitive data from exposure to unauthorized personnel with physical access to the computer.

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_CURRENT_USER Subkey: \Software\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: NoDispScrSavPage Type: REG_DWORD Value: 1

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.
