Section A4: Firewalls  ·  Cyber Essentials Danzell

What this question is really asking

If you have permitted inbound connections, describe your documented approval process. Each permitted inbound rule should have a named business justification, an approver, and a regular review date. Undocumented firewall rules are among the most common findings in Cyber Essentials assessments.

What satisfies this requirement

A written response is required

Business case documented, recorded, signed off at board level, risks reviewed regularly.

What to prepare before your assessor visit

Assessors will examine each inbound rule you describe. 'The business needs it' is not a sufficient justification — you need the specific service name, the ports and protocols permitted, who approved the rule, and when it was last reviewed. Old inbound rules approved years ago and never revisited since are among the most common firewall findings. Do the review before the assessment, not during it.
