Title
The operating system must conceal, via the session lock, information previously visible on the display with a publicly viewable image. (Cat III impact)
Discussion
A default screensaver must be configured for all users, as the screensaver will act as a session time-out lock for the system and must be one that conceals the contents of the screen from unauthorized users. The screensaver must not display any sensitive information or reveal the contents of the locked session screen. Publicly viewable images can include static or dynamic images such as patterns used with screen savers, photographic images, solid colors, a clock, a battery life indicator, or a blank screen.
Check Content
To view the currently selected screen saver for the logged in user, run the following command: system_profiler SPConfigurationProfileDataType | grep moduleName If there is no result or defined moduleName, this is a finding.
Fix Text
This setting is enforced using a configuration profile.
