Discussion

When operating system accounts are disabled, user accessibility is affected. Accounts are used for identifying individual users or operating system processes. To detect and respond to events affecting user accessibility and system processing, operating systems must audit account disabling actions.

Check Content

At the command line, run the following command:
 
 # auditctl -l | grep "w /usr/bin/passwd" 
 
 Expected result:
 
 -w /usr/bin/passwd -p x -k passwd
 
If the output does not match the expected result, this is a finding.

Note: This check depends on the auditd service to be in a running state for accurate results. The auditd service is enabled in control PHTN-30-000013.

Fix Text

Navigate to and open:

/etc/audit/rules.d/audit.STIG.rules

Add the following lines:
 
-w /usr/bin/passwd -p x -k passwd

At the command line, run the following command to load the new audit rules:

# /sbin/augenrules --load

Note: A new "audit.STIG.rules" file is provided for placement in "/etc/audit/rules.d" that contains all rules needed for auditd.

Note: An older "audit.STIG.rules" may exist if the file exists and references older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.
