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.

Copy theOCIDdisplayed (e.g., ocid1.instance.oc1..).

OCID of the Created Compute Instance

Enter the OCID of the created compute instance (IAD-SP-PBT-1-VM-01) into the text box. The exact OCID will be available after Step 9 (e.g., ocid1.instance.oc1..).

Notes

Ensure the security zone IAD_SAP-PBT-CSZ-01 and its associated recipe IAD-SP-PBT-CSP-01 allow compute instance creation in the public subnet (10.0.1.0/24).

Verify network connectivity by testing SSH access using the public IP assigned to the instance.

To create and configure a Virtual Cloud Network (VCN) named IAD-SP-PBT-VCN-01 with an Internet Gateway and appropriate route rules for external connectivity, follow these steps based on the Oracle Cloud Infrastructure (OCI) Networking documentation.

Step-by-Step Solution for Task 3: Create and Configure a VCN and Private Subnet

Log in to the OCI Console:

VCN CIDR Block:Enter 10.0.0.0/16 (matches the diagram's VCN CIDR).

Public Subnet CIDR Block:Enter 10.0.10.0/24 (matches the diagram's public subnet).

Accept the default settingsfor the public subnet and Internet Gateway creation.

ClickCreateto provision the VCN, Internet Gateway, and public subnet.

Verify the Internet Gateway:

After creation, go to the VCN details page for IAD-SP-PBT-VCN-01.

UnderResources, selectInternet Gateways.

Ensure the Internet Gateway is attached and enabled.

Configure Route Rules:

In the VCN details page, underResources, selectRoute Tables.

Select the default route table associated with the public subnet (10.0.10.0/24).

ClickAdd Route Rules.

Target Type:SelectInternet Gateway.

Destination CIDR Block:Enter 0.0.0.0/0.

Target Internet Gateway:Select the Internet Gateway created with the VCN.

ClickAdd Route Ruleto save.

Update Security List (if needed):

UnderResources, selectSecurity Lists.

Edit the default security list for the public subnet.

Add an ingress rule:

Source CIDR:0.0.0.0/0

IP Protocol:TCP

Source Port Range:All

Destination Port Range:22 (for SSH) or as required by your application.

Add an egress rule:

Destination CIDR:0.0.0.0/0

IP Protocol:All

Save the changes.

Note the VCN OCID:

Return to the VCN details page for IAD-SP-PBT-VCN-01.

Copy theOCIDdisplayed (e.g., ocid1.vcn.oc1..).

OCID of the Created VCN

Enter the OCID of the created VCN (IAD-SP-PBT-VCN-01) into the text box. The exact OCID will be available after Step 3 (e.g., ocid1.vcn.oc1..).

Task 7: Verify the OCI Certificate with Load Balancer

Step 1: Obtain the Public IP of the Load Balancer

Log in to the OCI Console.

Navigate toNetworking>Load Balancers.

Click on PBT-CERT-LB-01.

Note thePublic IP Addressfrom the load balancer details page.

Step 2: Verify HTTPS Connection Using Cloud Shell

Open the OCI Cloud Shell from the top-right corner of the OCI Console.

Run the following command, replacing with the public IP you noted:

curl -k https://

Expected output: You should see the text "You are visiting Web Server 1" if the connection is successful. The -k flag ignores certificate validation errors (common during initial testing with self-signed or newly issued certificates).

If you encounter an error, ensure the load balancer is active, the listener is configured correctly, and the backend server (PBT-CERT-VM-01) is reachable.

Step 3: Verify in a Web Browser

Open a web browser.

Enter the following URL, replacing with the public IP you noted:

https://

If prompted with a certificate warning (e.g., due to a self-signed certificate or untrusted CA), accept the risk and proceed (click "Advanced" and "Proceed" or similar, depending on your browser).

Verify that the web page displays the text "You are visiting Web Server 1" from the index.html file created on PBT-CERT-VM-01.

Step 4: Troubleshoot (if needed)

If the text is not displayed:

Check the load balancer health status underBackend Sets>Healthin the OCI Console.

Ensure the security list PBT-CERT-LB-SL-01 allows port 443 and the compute instance security list allows port 80.

Verify the Apache service is running on PBT-CERT-VM-01 by SSHing in and running sudo systemctl status httpd.
