Abstract
A secure boot monitoring and validation process during operating system (OS) upgrade operations from a previous OS version. A validated copy of OS boot files is made during OS installation. A checksum comparator or OS boot file filesystem check (FSCK) component validates the boot files upon initial installation of the OS. Any validation failure indicates corruption or unwanted modification of the boot file data. In case of a failure, an autorecovery operation using different boot partitions is attempted, and the OS boot filesystem check is performed again. If the second filesystem check fails a critical alert notification is sent, otherwise a warning alert notification is sent. The file system for storing user data is also shutdown to prevent any potential damage of user data.
