<h1 id="secure-boot">Secure Boot</h1>
<ul>
<li>Secure Boot is a <strong>security feature implemented in modern computer systems</strong>, primarily in those using the <strong>Unified Extensible Firmware Interface (UEFI) firmware.</strong></li>
<li>Its main purpose is to ensure that <strong>only trusted</strong> and <strong>authenticated software</strong> is loaded during the boot process, protecting the system against unauthorized or malicious code that could compromise its integrity and security.</li>
<li>During boot, UEFI Secure Boot checks the signature of each piece of boot software, including <strong>UEFI firmware drivers</strong> (also known as option ROMs), <strong>Extensible Firmware Interface</strong> (EFI) applications, and the operating system drivers and binaries. If the signatures are valid or trusted by the <strong>Original Equipment Manufacturer</strong> (OEM), the machine boots and the firmware gives control to the operating system.</li>
