SV-46075r1_rule The systems boot loader configuration file(s) must have mode 0600 or less permissive.

Vulnerability 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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
