The device's firmware is digitally signed and verified before execution to avoid tampering and unauthorized code execution. A hardware-based root of trust is utilized to protect the boot process from compromise. The secure boot process is critical to maintaining device integrity and preventing attacks such as malicious firmware updates, rootkits, and bootkits, which may compromise sensitive data or allow unauthorized control of the device.
Guide to Secure Boot Process
What is Secure Boot: Secure Boot is a security standard developed by members of the PC industry to help ensure that a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM).
Why it is important: The Secure Boot prevents attackers from loading malicious software and applications before the operating system loads. This offers protection against bootkit and rootkit attacks.
How it works: When your PC starts, the firmware checks the signature of each piece of boot software, including firmware drivers (Option ROMs) and the operating system. If the signatures are valid, the PC boots, and the firmware gives control to the operating system.
