Secure start-up systems assist to safeguard sensitive data, prevent any unauthorized modifications and ensure only certified and digitally signed programs are run. This is particularly important when working with devices on the edge and vulnerable to attack.

Secure Boot is a protocol that is part of UEFI (Unified Extensible Firmware Interface) that is activated every time the system starts. It is in sync with TPM (Trusted Platform Module) which is an instrument for security that is based on hardware and offers additional data protection where software-based security cannot.

With Secure Boot, the bootloader’s file has to be verified to be authentic prior to the operating system and other applications are able to be started. This ensures that the kernel and drivers are legitimate. Cryptography is used to implement the security mechanisms. To ensure that secure boot is effective, the code used in the bootloader operating system, as well as other functional applications should be created in a secure manner and thoroughly tested for any flaws in the course of the process of developing software.

If you’d like to utilize the secure startup feature of your LG device it is required to secure online storage have an PIN or pattern. If someone tries to guess your pin or pattern via trial and error for more than a certain number of times the device will be locked and require a password for access to restore functionality. This prevents any unauthorized access to your device as well as the information stored therein, and could also prevent accidental misuse by someone who could have gained physical access to it.
