Which of the following can help to secure the BIOS of a computer? (Select the two best answers.)

A. Use a case lock.
B. Use a BIOS supervisor password.
C. Configure a user password.
D. Disable USB ports.

A and B. By using a case lock or other type of locking mechanism for the computer case, a person cannot open the system and reconfigure the BIOS jumper. By configuring a BIOS supervisor password, only people who know the password can access the BIOS. User passwords can be configured for the BIOS, but these passwords are used only to prevent people who do not know the password from accessing the operating system. Disabling USB ports might be a good idea and can prevent persons from booting the system by way of a USB flash drive or other similar device but cannot help to secure the BIOS.
