A company is concerned about the potential risks associated with unauthorized modifications to the Basic Input/Output System (BIOS) firmware on its servers. The company has decided to implement hardening techniques and endpoint security controls to mitigate the risk.

Which technique will prevent unauthorized modifications to the BIOS firmware on a server?

Show Suggested Answer Hide Answer
Suggested Answer: B

BIOS protectioninvolves enabling hardware security features such asfirmware password protection,secure boot, andwrite protection, which prevent unauthorized firmware modifications.

NIST SP 800-147 (BIOS Protection Guidelines):

''Proper BIOS protection mechanisms, including authenticated updates and access control, are critical to maintaining the integrity of the platform's startup environment.''

This is apreventive control. BIOS monitoring is reactive; backups protect data, not firmware integrity.

Domain:System Security Engineering

Topic:Apply firmware and BIOS security controls to prevent low-level tampering

Agreed, D) is the way to go! Can't risk those firmware changes.

Wait, can BIOS protection really prevent all modifications? Sounds too good to be true.

Regular backups are important, but they won't stop unauthorized changes.

I think A) BIOS monitoring is also crucial, though.

Definitely D) BIOS protection! That's the best way to lock it down.

I’m a bit confused; I thought using an intrusion detection system could help, but I guess it’s more about detection than prevention.

I practiced a similar question about endpoint security, and I think BIOS protection is definitely the right choice for preventing modifications.

I think BIOS monitoring could be relevant, but I feel like it might not fully prevent unauthorized changes.

I remember studying BIOS protection techniques, but I'm not entirely sure if that's the best answer here.
