Montpellier A4.11

Do you have software firewalls enabled on all of your desktop computers, laptops and servers?

Section A4: Firewalls  ·  Cyber Essentials Montpellier

What this question is really asking

If remote firewall management is permitted, confirm it is protected by multi-factor authentication, IP allow-listing, or both. Assessors prefer to see both controls in place given the high risk of remote admin access to network infrastructure.

What satisfies this requirement

Yes or No

Software firewalls must be enabled even behind a physical boundary firewall. Check: Mac Security & Privacy, Windows Settings > Windows Firewall, Linux ufw status.

What to prepare before your assessor visit

If remote firewall management is permitted, assessors prefer to see both MFA and IP restriction in place. MFA alone is better than nothing, but a firewall admin interface reachable from any internet IP — even with MFA — presents a broader attack surface than one additionally restricted to your MSP's known IP ranges. Show the configuration for both controls.
