Information

A session 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. The operating system session lock event must include an obfuscation of the display screen so as 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.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

From the command prompt, run the following script to set the default timeout parameters "dtsession*saverTimeout:" and "dtsession*lockTimeout:" as "15" minutes:

# AIX7-00-001101_Fix.sh

Note: This script is included in the STIG package.
