The priority of a Web Application Firewall (WAF) policy is typically determined by the order in which the rules are configured and applied. In most WAF systems, rules are evaluated in a specific sequence, and the first rule that matches the incoming traffic will dictate the action taken.
For example, if you have two rules configured in your WAF:
When traffic arrives, the WAF will first check the first rule. If the traffic is from the specified IP address, it will be blocked immediately, regardless of the second rule. Only if the traffic does not match the first rule will the WAF proceed to evaluate the second rule.
In cloud environments, services like Tencent Cloud's Web Application Firewall offer flexible rule management and prioritization. You can customize the order of rules to suit your security requirements, ensuring that the most critical policies are enforced first.
This prioritization mechanism allows for precise control over how traffic is managed and protected, enabling organizations to tailor their security posture effectively.
