Tampering or malware attacks on the Windows boot sequence are blocked by the signature-enforcement handshakes between the UEFI, bootloader, kernel, and application environments. If any of these files were tampered, the bootloader detects the problem and refuses to load the corrupted component. The Windows kernel, in turn, verifies every other component of the Windows startup process, including boot drivers, startup files, and your antimalware product's early-launch antimalware (ELAM) driver. The Windows bootloader verifies the digital signature of the Windows kernel before loading it. Trusted Boot picks up the process that started with Secure Boot. Secure Boot then checks all code that runs before the operating system and checks the OS bootloader's digital signature to ensure that it's trusted by the Secure Boot policy and hasn't been tampered with. Malware attacks on the Windows boot sequence are blocked by the signature-enforcement handshakes throughout the boot sequence between the UEFI, bootloader, kernel, and application environments.Īs the PC begins the boot process, it will first verify that the firmware is digitally signed, reducing the risk of firmware rootkits. ![]() Secure Boot makes a safe and trusted path from the Unified Extensible Firmware Interface (UEFI) through the Windows kernel's Trusted Boot sequence. ![]() The first step in protecting the operating system is to ensure that it boots securely after the initial hardware and firmware boot sequences have safely finished their early boot sequences. Together, Secure Boot and Trusted Boot help to ensure your Windows 11 system boots up safely and securely. Secure Boot starts with initial boot-up protection, and then Trusted Boot picks up the process. Secure Boot and Trusted Boot help prevent malware and corrupted components from loading when a Windows 11 device is starting. This article describes Secure Boot and Trusted Boot, security measures built into Windows 11.
