Vulnerability discussion

Slide shows that are displayed on the lock screen could display sensitive information to unauthorized personnel. Turning off this feature will limit access to the information to a logged-on user.

Check content

Verify the registry value below. If it does not exist or is not configured as specified, this is a finding. Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\Personalization\ Value Name: NoLockScreenSlideshow Value Type: REG_DWORD Value: 0x00000001 (1)

Fix text

Configure the policy value for Computer Configuration >> Administrative Templates >> Control Panel >> Personalization >> "Prevent enabling lock screen slide show" 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.
