Web Application Firewall：Enable WAF protection for an MSE instance

Limits

Web services that use one of the following Alibaba Cloud services can be added to WAF in cloud native mode: Application Load Balancer (ALB), Microservices Engine (MSE), Function Compute, Classic Load Balancer (CLB), Elastic Compute Service (ECS), and Network Load Balancer (NLB).. If you want to use WAF to protect web services that do not use the preceding Alibaba Cloud services, add the domain names of the web services to WAF in CNAME record mode. For more information, see Add a domain name to WAF.

• The MSE instance for which you want to enable WAF protection must reside in one of the following regions: China (Hangzhou), China (Shanghai), China (Beijing), China (Ulanqab), China (Hong Kong), Singapore, Malaysia (Kuala Lumpur), China (Zhangjiakou), China (Shenzhen), Japan (Tokyo), Germany (Frankfurt), and US (Silicon Valley).

• You cannot enable the following features for MSE instances for which WAF protection is enabled:

  • Website tamper-proofing

  • Data leakage prevention

  • Automatic integration of the Web SDK in bot management for web application protection

Prerequisites

• A cloud-native gateway is created. For more information, see Create a cloud-native gateway.

• If you use a subscription WAF instance, make sure that the number of protected objects that you added to WAF does not exceed the upper limit. If the number exceeds the upper limit, you can no longer add cloud service instances to WAF.

  To view the number of protected objects that you can add to WAF, go to the Protected Objects page.

However, you are still charged feature fees for the protection rules that you configured for the MSE instance. We recommend that you delete protection rules before you remove an MSE instance from WAF. For more information, see Billable items and Protection module overview.
