Assessment Procedure

Check Text

Perform the following command with no parameters to ensure the system is in trusted mode.

# /bin/tcbck

If TCB is not installed, the output will show an error code of 3001-101 and/or a text message indicating TCB is not installed.  If the output from the command indicates it is not in trusted mode, this is not reviewed.  Otherwise, check the root crontab to verify tcbck is executed weekly.  If it is not in the crontab, ask the SA if the check is run manually and to see the results of the check.

Implementation Procedure

Fix Text

Add tcbck command as a weekly cronjob with the output sent to the SA.
