Vulnerability discussion

GRUB is a versatile boot loader used by several platforms that can provide authentication for access to the system or boot loader.

Check content

Determine if the system uses the GRUB boot loader; # ls -l /boot/grub/grub.conf If no grub.conf file exists, and the bootloader on the system has not been authorized, justified, and documented, this is a finding.

Fix text

Configure the system to use the GRUB bootloader or document, justify, and authorize the alternate bootloader.

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.
