Secure start-up systems safeguard sensitive data and ward off any unauthorized changes. They also ensure that only digitally signed and certified programs are executed. This is especially important when using devices that are on the edge that could be vulnerable to attack.

Secure Boot is a protocol in UEFI (Unified Extensible Firmware Interface) that runs every when the system starts. It is used in conjunction with TPM, a hardware-based data security tool.

Secure Boot checks the authenticity of the bootloader prior to permitting the operating system or other applications that are functional to be launched. This ensures that the kernel, drivers and other components are authentic. The underlying security mechanisms in this process are built on cryptography. For secure boot to be effective, the code used in the bootloader operating system, as well as other functional programs must be developed in a secure manner and thoroughly tested for flaws as part of the development process for software.

If you’d like to utilize the secure startup feature of your LG device it is required to have a PIN or pattern. If someone tries to guess your pin or pattern using trial and error for more than a certain amount of times the device will be locked and require a password to gain access in order to restore functionality. This prevents unauthorized access to the device and its information and prevents accidental misuse by anyone who might have physical access.
