Applying for Dedicated WAF Engines¶
If your service servers are deployed on the cloud, you can apply for dedicated WAF engines (or dedicated WAF instances) to protect important websites through domain names or web applications with only IP addresses.
Prerequisites¶
You have obtained management console login credentials for an account with the WAF Administrator and WAF FullAccess permissions.
A VPC is available.
Resource sets have been created.
Precautions¶
After your application for a dedicated WAF instance succeeds, its specifications cannot be modified.
Important
It takes about 10 minutes to create a dedicated WAF instance. If the instance is in the Running status, the instance has been created successfully.
Procedure¶
Log in to the management console.
Click
in the upper left corner of the management console and select a region or project.Click
in the upper left corner and choose Web Application Firewall under Security.If you are a first-time user for dedicated WAF instances, click Apply for Dedicated Engine Now on the left of the page.
Note
If you are not a first-time user for dedicated WAF instances, click Apply for Dedicate Engine in the upper right corner of the page.
On the Apply for Web Application Firewall page, set WAF instance parameters by referring to Table 1.
Table 1 Parameters of a dedicated WAF instance¶ Parameter
Description

AZ
Select an AZ in the selected region.
Instance Name Prefix
Set a prefix of the dedicated WAF instance name. If you apply for multiple instances at a time, the prefix to each instance name is the same.
Quantity

Security Group
Select a security group in the region or click Manage Security Group to go to the VPC console and create a security group. After you select a security group, the WAF instance will be protected by the access rules of the security group.
Important
NOTICE:
You can configure your security group as follows:
Inbound rules
Add an inbound rule to allow incoming network traffic to pass through over a specified port based on your service requirements. For example, if you want to allow access from port 80, you can add a rule that allows TCP and port 80.
Outbound rules
All outgoing network traffic is allowed by default.
If your dedicated WAF instance and origin server are not in the same VPC, enable communications between the instance and the subnet of the origin server in the security group.
In the lower right corner of the page, click Next.
Confirm the configuration and click Apply Now.
Click Back to Dedicated Engine List. On the Dedicated Engine page, view the instance status.
