Fix Recommendation

Configure the audit system to generate an audit event for any successful/unsuccessful uses of the "passwd" command.

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

-a always,exit -F path=/usr/bin/passwd -F perm=x -F auid>=1000 -F auid!=4294967295 -k privileged-passwd

The audit daemon must be restarted for the changes to take effect. To restart the audit daemon, run the following command:

# sudo systemctl restart auditd.service

Check Contents

Verify that an audit event is generated for any successful/unsuccessful use of the "passwd" command.

Check for the following system call being audited by performing the following command to check the file system rules in "/etc/audit/audit.rules":

# sudo grep -w passwd /etc/audit/audit.rules

-a always,exit -F path=/usr/bin/passwd -F perm=x -F auid>=1000 -F auid!=4294967295 -k privileged-passwd

If the command does not return a line, or the line is commented out, this is a finding.
