Check Text ( C-2059r2_chk )
For GRUB: Check the /etc/grub.conf or /boot/grub/menu.lst files. Procedure: # more /boot/grub/menu.lst Check for a password configuration line, such as the one below. password --md5 This line should be just below the line beginning with "timeout". Please note will be replaced by the actual MD5 encrypted password. If the password line is not in either of the files, this is a finding.

Fix Text (F-4160r2_fix)
