Secure start up systems help to safeguard sensitive data, prevent any unauthorized modifications and ensure only certified and digitally signed software is executed. This is particularly crucial when using devices at the edge that are vulnerable to attack.
Secure Boot is a protocol that is part of UEFI (Unified Extensible Firmware Interface) that runs every time the system is booted. It is in sync with TPM (Trusted Platform Module), which is a hardware-based security device that provides additional protection of data where software-based security can’t.
Secure Boot verifies the authenticity of the bootloader before allowing the operating system or other applications that are functional to be launched. This ensures that the kernel, drivers and other components are authentic. The security mechanisms that underlie this process are built on crypto. For secure boot to be effective, the code in the bootloader operating system, operating system and various functional applications must be developed carefully and thoroughly checked for any flaws in the course of the process of software development.
If you wish to enable secure startup on your LG device then you’ll need a PIN. If someone attempts to guess your pin or pattern via trial and error for more than a certain number of times, the device will lock and require a password for access to allow functionality. This is to prevent unauthorized access the device and its information as well as accidental misuse by anyone who could have physical access.
