Abstract
Embodiments are described for a secure boot monitoring and validation process during operating system (OS) installation and runtime. 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, and an alert is sent. The file system is locked to prevent any exposure of user data. The validated copy is then used to recover the boot files. An OS boot file monitor component periodically monitors the boot files during OS run time and if any corruption is detected during a system boot after OS installation, the boot blocking, alert, and recovery procedures can be invoked.
