What is a firewall?
A firewall filters network traffic according to rules that allow or block connections. In cloud environments this is usually done with security groups and network access control lists (ACLs). Firewall management covers how rules are designed, changed, reviewed, and removed.
What the buyer is really asking
In the cloud "firewall" usually means security groups and network ACLs. Describe the default-deny posture, who can change rules, and how changes are reviewed. Managing the rules as code with review is the strongest evidence.
Other ways buyers ask it
Every one of these wants the same answer:
- “Describe your firewall configuration and management.”
- “How are firewall rule changes approved?”
- “How often are firewall rules reviewed?”
- “What is your process for making changes to network configuration?”
Evidence to have ready
- Security group or firewall rules in infrastructure as code
- A record of the last firewall rule review
