How Secure Boot Works

Secure Boot in Windows 10 works by checking the digital signatures of each component involved in the boot process. These components include the firmware, bootloader, kernel, and device drivers. When the system is powered on, the firmware, such as Unified Extensible Firmware Interface (UEFI), initiates the Secure Boot process. The firmware contains a set of public keys, typically installed by the device manufacturer, called Secure Boot Keys or Platform Keys. These keys are used to verify the digital signatures of the bootloader and subsequent components.

During the boot process, if any component has an invalid or missing digital signature, Secure Boot will prevent it from loading, displaying a warning or error message to the user. This ensures that only trusted and authenticated software is executed, reducing the risk of malware or unauthorized modifications from compromising the system. Secure Boot also mitigates the risk of rootkits and bootkits, as they rely on executing malicious code during the boot process to gain persistence and control over the operating system.

Secure Boot also provides protection against unauthorized firmware modification. It helps detect tampering attempts by verifying the firmware's digital signature before allowing it to load. This prevents attackers from modifying the firmware to inject malicious code or backdoors, ensuring the overall integrity of the system. Secure Boot in Windows 10 complements other security features, such as Windows Defender Antivirus and Windows Defender System Guard, to provide a layered defense against sophisticated and persistent threats.
