Fix Recommendation

Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "unix_chkpwd" command occur.

Add or update the following rule in "/etc/audit/rules.d/audit.rules":

-a always,exit -F path=/usr/sbin/unix_chkpwd -F auid>=1000 -F auid!=unset -k privileged-passwd

The audit daemon must be restarted for the changes to take effect.

Check Contents

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "unix_chkpwd" command occur.

Check the file system rule in "/etc/audit/audit.rules" with the following command:

# grep -iw /usr/sbin/unix_chkpwd /etc/audit/audit.rules

-a always,exit -F path=/usr/sbin/unix_chkpwd -F auid>=1000 -F auid!=unset -k privileged-passwd

If the command does not return any output, this is a finding.
