Secure start-up systems assist to safeguard sensitive data, stop modifications that are not authorized and ensure that only certified and digitally signed programs are executed. This is particularly important when working with devices on the edge that are vulnerable to attack.

Secure Boot is a protocol in UEFI (Unified Extensible Firmware Interface) which is active every time the system boots. It works in conjunction with TPM the hardware-based data security tool.

With Secure Boot the bootloader’s file is verified to be authentic prior to the operating system and other functional applications are able to be started. This ensures that the kernel and drivers are authentic. The security mechanisms behind this process are based on crypto. Secure boot is only feasible if the code that is used for the bootloader and operating system, and also other functional applications, has been designed in a secure manner and thoroughly tested during the development of software.

If you wish to use the secure startup feature of your LG device, you must have a PIN or a pattern. If someone tries to guess your pin or pattern via trial and error more than a certain amount of times, the device will lock and require a password to gain access to restore functionality. This stops unauthorized access to the device and its information as well as accidental misuse by anyone who might have physical access.
