Challenge 4 - Task 4 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:

Create a WAF policy with the nameIAD-SP-PBT-WAF-01_99233424-lab.user01

Eg: IAD-SP-PBT-WAF-01_99232403-lab.user02

c) Action: Keep the default preconfigured actions; do not edit.

d) Click the Select enforcement point section accessible from the left-side navigation.

Note: You will configure the other section later in this practice. You will directly configure the Enforcement point.

In the Select enforcement point section:a) Add Firewalls: Select a load balancer IAD-SP-PBT-LB-01 in your current compartment from the list. b) Click Next for Review and Create.

Under the Review and Create Section:a) Verify the enforcement point added in the previous step.

Click Create WAF Policy.

Ah, I see we need to create a specific WAF policy name. That's a nice detail to watch out for.
