Fix Recommendation

Configure the SUSE operating system to generate an audit record when all modifications to the "/etc/shadow" file occur.

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

-w /etc/shadow -p wa -k account_mod

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

# sudo systemctl restart auditd.service

Check Contents
