Discussion

File permissions greater than 0600 on boot loader configuration files could allow an unauthorized user to view or modify sensitive information pertaining to system boot instructions.

Check Content

Check /etc/zipl.conf permissions:

# ls –lL /etc/zipl.conf

If /etc/zipl.conf has a mode more permissive than 0600, then this is a finding.

Fix Text

Change the mode of the zipl.conf file to 0600.

# chmod 0600 /etc/zipl.conf
