Challenge 3 - Task 4 of 4
Set Up a Bastion Host to Access the Compute Instance in a Private Subnet Scenario
A compute instance is provisioned in a private subnet that is not accessible through the Internet. To access the compute instance resource in a private subnet, you must provide a time-bound SSH session without deploying and maintaining a public subnet and a jump server, which eliminates the hassle and potential attack surface from remote access.
To complete this deployment, you have to perform the following tasks in the environment provisioned for you:
• Configure a Virtual Cloud Network (VCN) and a Private Subnet.
• Provision a Compute Instance in the private subnet and enable Bastion Plugin.
• Create a Bastion and Bastion session.
• Connect to a compute instance using Managed SSH session.
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 tasks in the provisioned OCI environment:
Connect to a compute instance using a Managed SSH Bastion session from your local machine terminal or Cloud shell.
Challenge 4 - Task 2 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: /index.html? ) To complete this deployment, you have to perform the following tasks in the environment provisioned for you: 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: b. Enable Apache and start Apache server: c. Create a firewall rule to enable HTTP connection through port 80 and reload the firewall: d. Create an index file for your web server:

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).
Challenge 2
Least-Privileged Model Enforcement Leveraging Custom Security Zones
Scenario
In deploying a new application, a cloud customer needs to reflect different security postures. If a security zone is enabled with the Maximum Security Zone recipe, the customer will be unable to create or update a resource in the Security Zone if the action violates the attached Maximum Security Zone policy.
As an application requirement, the customer requires a compute instance in the public subnet. You, therefore, need to configure Custom Security Zones that allow the creation of compute instances in the public subnet.
To complete this deployment, you have to perform the following tasks in the environment provisioned for you:
• Create a Custom Security Zone recipe to allow compute instances in the public subnet.
• Create a Security Zone using the Custom Security Zone recipe.
• Configure a Virtual Cloud Network (VCN) and Public Subnet.
• Provision a Compute Instance in the public subnet.
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 provisioned OCI environment:
