How does the Firebox validate firewall policies?

The Firebox validates firewall policies by processing rules in a specific order. This order is crucial because the Firebox evaluates each policy based on its sequence within the configuration. Once a packet matches a policy rule, the corresponding action is applied, and no further rules are processed for that packet. This means that understanding the hierarchy and order of rules is essential for effective policy implementation. Higher-priority rules are evaluated before lower-priority ones, ensuring that the most critical security measures are enforced first. If policies were processed randomly or with no regard to priority, it could lead to unintended access or vulnerabilities, as some rules might not have the desired effect. The structured approach to rule processing thus ensures that the firewall behaves predictably and aligns with the intended security posture.
