Converge Cloud provides two types of cloud WAF, namely, SaaS WAF and CLB WAF. They have basically the same security protection capabilities but different connection methods and use cases. You can select an appropriate WAF type based on your actual deployment.
CLB WAF
Connect Method Overview
| Connect Type | Connect Steps |
|---|---|
| CLB Domain Onboarding | Configure the domain and Layer-7 Load Balancer (CLB) resources (listeners) in the WAF console. This allows bypass threat detection and cleansing of HTTP/HTTPS traffic passing through the load balancer listener, achieving separation of business forwarding and security protection. |
| CLB Instance Object Onboarding | Enable Layer-7 Load Balancer (CLB) instance connect to WAF in the WAF console. This allows bypass threat detection and cleansing of HTTP/HTTPS traffic passing through the load balancer instance, achieving separation of business forwarding and security protection. |
| API Gateway and Serverless Cloud Function Domain Onboarding | Enable WAF protection through the API Gateway console (refer to API Gateway product documentation) and SCF console, then configure the domain in the WAF console. This allows bypass threat detection and cleansing of HTTP/HTTPS traffic passing through the API Gateway and SCF, achieving separation of business forwarding and security protection. |
| API Gateway Instance Object Onboarding | Enable WAF protection in the API Gateway console (refer to API Gateway product documentation) and in the WAF console, then enable API Gateway (instance) connect to WAF. This allows bypass threat detection and cleansing of HTTP/HTTPS traffic passing through the API Gateway instance, achieving separation of business forwarding and security protection. |
Traffic Processing Mode
CLB WAF provides two traffic processing modes:
Protection mode
By associating through the domain, CLB, API Gateway, and SCF forward business traffic to the WAF cluster, where WAF performs bypass detection and alerts, synchronizes the request's trusted status, and the gateway cluster intercepts or allows the request based on the status.
Mirror mode
By associating through the domain, CLB mirrors traffic to the WAF cluster, where WAF performs bypass detection and alerts, without returning the request's trusted status
