SV-51758r2_rule A screen saver must be enabled on the system.

Vulnerability discussion

Unattended systems are susceptible to unauthorized use and must be locked when unattended. Enabling a password-protected screen saver to engage after a specified period of time helps protects critical and sensitive data from exposure to unauthorized personnel with physical access to the computer.

Check content

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_CURRENT_USER Registry Path: \Software\Policies\Microsoft\Windows\Control Panel\Desktop\ Value Name: ScreenSaveActive Type: REG_SZ Value: 1 Applications requiring continuous, real-time screen display (e.g., network management products) require the following and must be documented with the ISSO: -The logon session does not have administrator rights. -The display station (e.g., keyboard, monitor, etc.) is located in a controlled access area.

Fix text

Configure the policy value for User Configuration -> Administrative Templates -> Control Panel -> Personalization -> "Enable screen saver" to "Enabled".

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.
