Secure start-up systems help to protect sensitive data, stop unauthorized changes and ensure that only certified and digitally signed programs are run. This is especially important when using devices on the edge and vulnerable to attack.
Secure Boot is a protocol that runs in UEFI, the Unified Extensible Firmware Interface. It operates each time the system starts. It is used in conjunction with the TPM, a hardware-based data security tool.
Secure Boot checks the authenticity of the bootloader before allowing the operating system, or other functional applications to be launched. This helps ensure that the kernel and drivers are legitimate. The security mechanisms behind this process are built on crypto. Secure boot is only feasible if the code used for the bootloader and operating system, along with other functional applications has been developed securely and thoroughly tested during the process of software development.
If you wish to enable secure startup on your LG device then you’ll require a PIN. If someone attempts to guess your pin or pattern by trial and error for more than a predetermined number of times the device will be locked and require a password for access in order to restore functionality. This helps to prevent unauthorised access to your device and the data on it, and can also keep accidental misuse by someone who could have gained physical access to it.
