To create a Security Zone named IAD_SAP-PBT-CSZ-01 in your assigned compartment and associate it with the Custom Security Zone Recipe IAD-SP-PBT-CSP-01 created in the previous task, follow these steps based on the Oracle Cloud Infrastructure (OCI) Security Zones documentation.

Step-by-Step Solution for Task 2: Create a Security Zone

Log in to the OCI Console:

Use your OCI credentials to log in to the OCI Console (https://console.us-ashburn-1.oraclecloud.com ).

Ensure you have access to the assigned compartment.

Navigate to Security Zones:

From the OCI Console, click the navigation menu (hamburger icon) on the top left.

UnderGovernance and Administration, selectSecurity Zones.

Create a New Security Zone:

In the Security Zones dashboard, click theCreate Security Zonebutton.

Configure the Security Zone Details:

Name:Enter IAD_SAP-PBT-CSZ-01.

Compartment:Select the assigned compartment provided.

Description:(Optional) Add a description, e.g., "Security Zone for public subnet compute instances."

Associate the Custom Security Zone Recipe:

In theRecipesection, select the custom recipe IAD-SP-PBT-CSP-01 created in Task 1 from the dropdown list.

Ensure the recipe is correctly associated to enforce the policy allowing compute instances in the public subnet.

Define the Security Zone Scope:

UnderResources to Protect, select the compartment or specific resources (e.g., the VCN with CIDR 10.0.0.0/16 and public subnet 10.0.10.0/24) to apply the security zone.

Check the box to include all resources in the selected compartment if applicable.

Create the Security Zone:

ClickCreateto finalize the security zone creation.

Once created, note theOCIDof the security zone from the security zone details page. The OCID will be a unique identifier starting with ocid1.securityzone.

Verify the Security Zone:

Go to theSecurity Zonestab and locate IAD_SAP-PBT-CSZ-01.

Confirm the associated recipe (IAD-SP-PBT-CSP-01) and the applied policies.

OCID of the Created Security Zone

The exact OCID will be generated upon creation (e.g., ocid1.securityzone.oc1..). Please enter the OCID displayed in the OCI Console after completing Step 7.

Task 6: Create Load Balancer and Attach Certificate

Step 1: Create the Load Balancer

Log in to the OCI Console.

Navigate toNetworking>Load Balancers.

ClickCreate Load Balancer.

Enter the following details:

Step 2: Create a Listener

Once the load balancer is created, go to theLoad Balancerspage and click on PBT-CERT-LB-01.

UnderResources, clickListeners.

ClickCreate Listener.

Enter the following details:

Name: PBT-CERT-LB_LTSN_01

Protocol: SelectHTTPS.

Port: Enter 443.

Certificate: ClickAdd Certificate, then select the PBT-CERT-01 certificate (e.g., PBT-CERT-0199008677labuser01) created in Task 5.

ClickCreate.

Step 3: Configure the Backend Set

In the PBT-CERT-LB-01 details page, underResources, clickBackend Sets.

ClickCreate Backend Set(if not already created).

Enter basic details (e.g., name like PBT-CERT-BS-01).

Add a backend server:

IP Address: Use the private IP of PBT-CERT-VM-01 (find this in the instance details underCompute>Instances).

Port: 80 (HTTP, as configured on the web server).

Protocol: HTTP.

ClickCreate.

Step 4: Attach the Security List to the Subnet

Navigate toNetworking>Virtual Cloud Networks.

Select PBT-CERT-VCN-01 and clickSubnets.

Click on LB-Subnet-PBT-CERT-SNET-02.

UnderSecurity Lists, ensure PBT-CERT-LB-SL-01 is attached. If not:

ClickEdit.

Remove the default security list and add PBT-CERT-LB-SL-01.

ClickSave Changes.

Step 5: Verify the Configuration

Ensure the load balancer health status is OK (check underBackend Sets>Health).

Test by accessing https:// in a browser (replace with the public IP from the load balancer details).

Task 2: Create a Compute Instance and Install the Web Server

Step 1: Create the Compute Instance

Log in to the OCI Console.

Navigate toCompute>Instances.

ClickCreate Instance.

Enter the following details:

Name: PBT-CERT-VM-01

Compartment: Select your assigned compartment.

Placement: Leave as default or select an availability domain (e.g., Availability Domain 1).

Image: ClickChange Image, selectOracle Linux 8, and confirm.

Shape: ClickChange Shape, selectVM.Standard.A1.Flex, and configure:

OCPUs: 1 (or adjust as needed)

Memory: 6 GB (or adjust as needed)

Networking:

Virtual Cloud Network: Select PBT-CERT-VCN-01.

Subnet: Select Compute-Subnet-PBT-CERT.

Leave public IP assignment enabled for internet access.

SSH Key: Provide your public SSH key (upload or paste) for secure access.

ClickCreateand wait for the instance to be provisioned.

Step 2: Connect to the Compute Instance

Once the instance is created, note thePublic IP Addressfrom the instance details page.

Use an SSH client to connect:

Command: ssh -i opc@

Replace with your private key path and with the instance’s public IP.

Step 3: Install and Configure Apache Web Server

Install Apache:

Run: sudo yum -y install httpd

Enable and Start Apache:

Run: sudo systemctl enable httpd

Run: sudo systemctl restart httpd

Configure Firewall to Allow HTTP Traffic (Port 80):

Run: sudo firewall-cmd --permanent --add-port=80/tcp

Run: sudo firewall-cmd --reload

Create an index.html File:

Run: sudo bash -c 'echo "You are visiting Web Server 1" >> /var/www/html/index.html'

Step 4: Verify the Configuration

Open a web browser and enter http:// to ensure the page displays "You are visiting Web Server 1".

If needed, troubleshoot by checking Apache status: sudo systemctl status httpd.

Step 5: Retrieve and Enter the OCID

Go to the instance details page for PBT-CERT-VM-01 underCompute>Instances.

Copy theOCID(a long string starting with ocid1.instance., unique to your tenancy).

Enter the copied OCID exactly as it appears into the text box provided.

Notes

These steps are based on OCI Compute documentation and Oracle Linux 8 setup guides.

Ensure the security list PBT-CERT-CS-SL-01 allows inbound traffic on port 22 (SSH) and port 80 (HTTP) if not already configured.

The OCID will be unique to your instance; obtain it from the OCI Console after creation

To create a public subnet named IAD-SP-PBT-PUBSNET-01 within the VCN IAD-SP-PBT-VCN-01 using a CIDR block of 10.0.1.0/24 and configure it to use the Internet Gateway, follow these steps based on the Oracle Cloud Infrastructure (OCI) Networking documentation.

Step-by-Step Solution for Task 4: Create a Public Subnet

Log in to the OCI Console:

Use your OCI credentials to log in to the OCI Console (https://console.us-ashburn-1.oraclecloud.com ).

Ensure you have access to the assigned compartment.

Navigate to Virtual Cloud Networks:

From the OCI Console, click the navigation menu (hamburger icon) on the top left.

UnderNetworking, selectVirtual Cloud Networks.

Select the VCN:

Locate and click on the VCN named IAD-SP-PBT-VCN-01 created in Task 3.

UnderResources, selectSubnets.

Create a New Subnet:

Click theCreate Subnetbutton.

Configure the Subnet Details:

Name:Enter IAD-SP-PBT-PUBSNET-01.

Compartment:Ensure it is set to the assigned compartment.

Subnet Type:SelectPublic Subnet.

CIDR Block:Enter 10.0.1.0/24.

Route Table:Select the default route table associated with the VCN (ensure it includes a route to the Internet Gateway with destination 0.0.0.0/0).

Subnet Access:SelectPublic Subnetand ensure the Internet Gateway is associated.

DHCP Options:Leave as default or customize if required.

Security List:Use the default security list or create a new one with appropriate ingress/egress rules (e.g., allow TCP port 22 for SSH and all egress traffic).

Associate the Internet Gateway:

Verify that the subnet is configured to route traffic through the Internet Gateway. This is automatically handled if you selected the public subnet option and the VCN’s route table is correctly set (as configured in Task 3).

If needed, edit the route table for the subnet to ensure a rule exists:

Destination CIDR Block:0.0.0.0/0

Target Type:Internet Gateway

Target:Select the Internet Gateway associated with IAD-SP-PBT-VCN-01.

Create the Subnet:

ClickCreateto provision the subnet.

Once created, the subnet will be listed under the VCN’s subnets.

Verify the Configuration:

Go to the subnet details page for IAD-SP-PBT-PUBSNET-01.

Confirm the CIDR block is 10.0.1.0/24 and that it is a public subnet with Internet Gateway access.

Notes

Ensure the CIDR block 10.0.1.0/24 does not overlap with existing subnets in the VCN (10.0.0.0/16, including 10.0.10.0/24 from Task 3).

The Internet Gateway association relies on the route table configuration from Task 3. If it’s missing, update the route table as described in Step 6.
