Medium Severity
<VulnDiscussion>A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system, but does not log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. This is typically at the operating system level, but may be at the application level. When the application design specifies the application rather than the operating system will determine when to lock the session, the application session lock event must include an obfuscation of the display screen to prevent other users from reading what was previously displayed. Publicly viewable images can include static or dynamic images, for example, patterns used with screen savers, photographic images, solid colors, a clock, a battery life indicator, or a blank screen, with the additional caveat that none of the images convey sensitive information.
