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.
