Explanation
A backend security policy is required because the Cloud Armor rules must apply to traffic after it passes through the third-party WAF and reaches the backend service. The userIpRequestHeaders[] attribute extracts the original client IP from headers inserted by the WAF (e.g., X-Forwarded-For). The rule checks if the client's IP falls within the IP_RANGE_BLOCK range and denies the traffic. This ensures Cloud Armor blocks traffic based on the actual client IP, as the third-party WAF creates a new connection using its IP for proxied traffic.
