📚 Topic Summary
The BIOS (Basic Input/Output System) is the first software to run when a computer is turned on. It initializes hardware and loads the operating system. Securing the BIOS is crucial because if it's compromised, attackers can control the entire system. BIOS security features include passwords, boot order control, and secure boot, which ensure that only trusted software is loaded during startup. Worksheets focusing on BIOS Security help students understand cybersecurity basics by exploring these fundamental security mechanisms.
