What is Secure Boot and why is it important?
Secure Boot is a security feature found in modern BIOS/UEFI firmware that helps ensure only trusted software is loaded during the boot process. It works by requiring all boot components—such as the operating system, drivers, and other boot-related files—to be signed by a recognized certificate authority. This helps prevent the execution of unauthorized or malicious software that could compromise the integrity of the system, thereby enhancing overall security.
The importance of Secure Boot lies in its ability to defend against common attack vectors such as bootkits and rootkits, which can load before the operating system and operate undetected. By ensuring that only validated software is allowed to run, Secure Boot plays a crucial role in maintaining the trustworthiness of a computer’s operating environment, encouraging users to adopt more secure practices.
How do I enable Secure Boot on my ASUS laptop?
To enable Secure Boot on your ASUS laptop, you will first need to access the UEFI firmware settings.
