Safer Firewall Policy Automation

Firewall automation must preserve intent, ownership, and an explainable path back to the request.

Model intent first

Represent source, destination, service, environment, owner, expiry, and justification before translating anything into vendor syntax.

Detect dangerous overlap

Check shadowing, broad objects, unexpected zones, duplicate policy, and missing expiry. A syntactically valid rule can still violate the requested boundary.

Close the loop

Validate candidate policy, require review for sensitive scope, apply through a narrow interface, then confirm installation, hit behavior, and monitoring.

Field rule

The safest automated rule is the smallest rule that satisfies a verified business path.
