Challenge 4 - Task 5 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://<public- ip-enforcement-point>/index.html?<p style="background:url(javascript:alert(1))"](http://<public- ip-enforcement-point>/index.html?<p style="background:url(javascript:alert(1))">) 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:
1. Create a Protection Rule with name WAF-PBT-XSS-Protection against XSS attack. for protecting web server
2. Create a New Rule Action with name WAF-PBT-XSS-Action where http response code will be 503 (Service Unavailable).

You create a new compartment, "apps," to host some production apps and you create an apps_group and added users to it.
What would you do to ensure the users have access to the apps compartment?

Which Cloud Guard component identifies issues with resources or user actions and alerts you when an issue is found?

Challenge 1 - Task 1 of 5
Authorize OCI Resources to Retrieve the Secret from the Vault
Scenario:
You are working on a Python program running on a compute instance that needs to access an external service. To access the external service, the program needs credentials (password). Given that it is not a best security practice, you decide not to hard code the credential in the program. Instead, you store the password (secret) in a vault using the OCI Vault service. The requirement now is to authorize the compute instance so that the Python program can retrieve the password (secret) by making an API call to the OCI Vault.

Preconfigured:
To complete this requirement, you are provided with:
An OCI Vault to store the secret required by the program, which is created in the root compartment as PBT_Vault_SP.
An instance principal IAM service, which enables instances to be authorized actors (principals) that can retrieve the secret from the OCI Vault.
A dynamic group named PBT_Dynamic_Group_SP with permissions to access the OCI Vault. This dynamic group includes all of the instances in your compartment.
Access to Cloud Shell.
Permissions to perform only the tasks within the challenge.
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 99234021-C01 and Region us-ashburn-1.
Complete the following tasks in the OCI environment provisioned:
Create Master Encryption Key with the name my_pbt_msk with 256 bits shape.
Create a Secret with the name my-pbt-secret_99234021-lab.user01 and secret content.
For example: If your user name is 99346163-lab.user02, then the secret should be named as my-pbt-secret_99346163-lab.user02.
