The correct answer is C. Allowing only digitally signed modules to load. To prevent attackers from gaining control during the boot process and altering data flow on kiosk workstations, ensuring only digitally signed modules can load is the most effective solution.
Question
A company that provides kiosk workstations wants to improve the workstations' security implementation. The company is concerned that attackers can take control of the workstations during the boot process and change the flow of the data. Which of the following solutions best addresses the concerns?
Options

- BRemoving any unused connection ports
- CAllowing only digitally signed modules to load
- DCreating bootloader passwords

Why each option
To prevent attackers from gaining control during the boot process and altering data flow on kiosk workstations, ensuring only digitally signed modules can load is the most effective solution.
Setting controls to allow only specific operating systems is a policy choice that does not inherently prevent malicious modules from loading during the boot process if the authorized OS is compromised or bypassed.
Removing any unused connection ports reduces physical attack vectors but does not address software-based attacks during the boot process itself.
Allowing only digitally signed modules to load, a core feature of Secure Boot, ensures that only trusted and verified software components can execute during the system's boot process. This directly prevents attackers from injecting or modifying boot components to take control and alter data flow before the operating system fully loads.
Creating bootloader passwords offers a basic security layer but can be bypassed by sophisticated attackers with physical access or by exploiting vulnerabilities in the boot process before the password prompt.
