What the check covers

Firewall configuration areas the check reviews

Firewalls rarely fail because of the hardware. They fail because rules and settings drift over years of quick changes. The check covers the areas where that drift happens.

01

Rule base hygiene

Old, unused, duplicate or overly broad rules that nobody can explain anymore.

02

Inbound exposure

Services published to the internet, such as remote desktop, file transfer or management pages.

03

Outbound control

Whether internal systems can reach any destination, or only what the business needs.

04

Administrative access

Who can manage the firewall, from where, and whether MFA and named accounts are used.

05

Firmware and support

Whether the firewall runs supported, current firmware and receives security updates.

06

Logging and change control

Whether rule changes are approved and recorded, and whether logs are kept and reviewed.

Risky patterns

Risky firewall rule patterns and safer alternatives

These patterns appear in many small and mid-sized business firewalls. Each has a straightforward safer alternative.

Risky patternWhy it is riskySafer alternative
Any source to any destination on any portAllows everything the rule matches, defeating the purpose of the firewall.Specific sources, destinations and ports for a documented business need.
Remote desktop open to the internetA frequent entry point for ransomware.Remote access through VPN or a remote access gateway with MFA.
Firewall management reachable from the internetExposes the device that protects everything else.Management limited to internal admin networks or a secured portal.
Temporary rules left in placeExceptions outlive the project that needed them.An expiry date and owner on every temporary rule.
Shared admin accountNo accountability for changes.Named admin accounts with MFA and change logging.

Questions

Firewall configuration risk check: common questions

Is the firewall configuration risk check free?

Yes. It is a free self-assessment based on your answers. It does not connect to or scan your firewall.

How often should firewall rules be reviewed?

At least once a year, and after major changes such as a new office, new applications or a firewall replacement.

Does this check work for any firewall brand?

Yes. The questions apply to common business firewalls, including Cisco, Meraki, Fortinet, Palo Alto Networks, SonicWall and Sophos.

What should we fix first?

Anything exposing remote desktop or firewall management to the internet, followed by broad "any" rules and shared admin accounts.
