What is Secure Boot?
Secure boot is a security standard that ensures that only trusted software executed on the system has been approved by the PC manufacturers. PC manufacturers make it to secure the system from malicious software execution. It supports modern Windows, Linux, etc. When secure boot is enabled from the firmware the system matches the signature of executable files before allowing the file to execute.
It safeguards our system against the execution of malicious and unauthorized codes. When we start the PC, the firmware checks the signature of each boot software, if the signatures are matched, then the system boots and control is given to the operating system from the firmware. Secure boot doesn’t need TPM and it also doesn’t encrypt the storage of the system.
Example:- When we first power on the modern PC with UEFI firmware secure boot comes into action before allocating resources to the memory. It supports Windows, Linux, and macOS.
