The Basic Input/Output System is a firmware that initializes and manages hardware components during the computer’s boot process.
It is the first software that runs when you turn on your computer. It provides a crucial interface between the operating system and the hardware, ensuring the computer starts properly.
Unfortunately, hackers can target BIOS to access the system. A compromised BIOS can weaken the operating system and other essential security measures.
Common BIOS Applications in Cybersecurity
- BIOS firmware updates: Updating BIOS and installing the latest security patches helps to protect the system from common vulnerabilities.
- Secure boot: This feature allows the BIOS to ensure that only trusted software is activated during the boot process, providing effective protection against threats compromising system integrity.
Why is BIOS Important?
- Boot process initialization: BIOS initiates the boot process by performing a Power-On Self-Test (POST) to ensure the system’s hardware components work correctly before loading the operating system.
