Web App Firewall (WAF)

Creating and Using a WAF in DuploCloud AWS
The creation of a Web Application Firewall (WAF) is a one-time process. Create a WAF in the Azure Console, fetch the ID/ARN, and update the Plan in DuploCloud. Once updated, the WAF can be attached to the Load Balancer.

Creating a Web Application Firewall (WAF)

When you create a WAF in DuploCloud, an entry is added to the AWS Web ACL. You use this entry in a later step to attach an ALB Load Balancer to your WAF.
  1. 1.
    In the DuploCloud Portal, navigate to Administrator -> Plans. The Plans page displays.

Analyzing inbound traffic with the WAF dashboard

DuploCloud also provides a WAF Dashboard through which you can analyze the traffic that is coming in and the requests that are blocked. The Dashboard can be accessed from the left navigation panel: Security > WAF.
