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