Challenge 4 - Task 3 of 6

Configure Web Application Firewall to Protect Web Server Against XSS Attack

Scenario

You have to protect web applications hosted on OCI from cross-site scripting (XSS) attacks. You can use the OCI Web Application Firewall (WAF) capabilities to create rules that compare against incoming requests to determine if the request contains an XSS attack payload. If a request is determined to be an attack, WAF should return the HTTP Service Unavailable (503) error.

To ensure that the configured WAF blocks the XSS attack, run the following script:[http:///index.html?

/index.html?

)

To complete this deployment, you have to perform the following tasks in the environment provisioned for you:

Configure a Virtual Cloud Network (VCN)

Create a Compute Instance and install the Web Server

Create a Load Balancer and update Security List

Create a WAF policy

Configure Protection Rules against XSS attacks

Verify the created environment against XSS attacks

Note:You are provided with access to an OCI Tenancy, an assigned compartment, and OCI credentials. Throughout your exam, ensure to use the assigned Compartment 99233424-C01 and Region us-ashburn-1.

Complete the following task in the provisioned OCI environment:

Go to the VCN IAD-WAF-PBT-VCN-01.

Create a Security List with the name IAD-SP-PBT-LB-SL-01.

Create a Public subnet named LB-Subnet-IAD-SP-PBT-SNET-02 and attach the above-created security list.

Create a Load Balancer with the name IAD-SP-PBT-LB-01.

Create a Listener Name with the name IAD_SP_PBT_LB_LISN_01.

Add appropriate Ingress and Egress rules to IAD-SP-PBT-LB-SL-01, to allow http traffic to the Load Balancer subnet.
