What you'll learn

In this lab, you will perform the following tasks:

• Understand the lab topology.
• Secure VPC network traffic with VM-Series.
• Autoscale the VM-Series with cloud workloads.

Setup and requirements

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources are made available to you.

This hands-on lab lets you do the lab activities in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials you use to sign in and access Google Cloud for the duration of the lab.

To complete this lab, you need:

• Access to a standard internet browser (Chrome browser recommended).

• Time to complete the lab—remember, once you start, you cannot pause a lab.

How to start your lab and sign in to the Google Cloud console

1. Click the Start Lab button. If you need to pay for the lab, a dialog opens for you to select your payment method. On the left is the Lab Details pane with the following:

   • The Open Google Cloud console button
   • Time remaining
   • The temporary credentials that you must use for this lab
   • Other information, if needed, to step through this lab

2. Click Open Google Cloud console (or right-click and select Open Link in Incognito Window if you are running the Chrome browser).

   The lab spins up resources, and then opens another tab that shows the Sign in page.

   Tip: Arrange the tabs in separate windows, side-by-side.

   Note: If you see the Choose an account dialog, click Use Another Account.

3. If necessary, copy the Username below and paste it into the Sign in dialog.

   {{{user_0.username | "Username"}}}

   You can also find the Username in the Lab Details pane.

4. Click Next.

5. Copy the Password below and paste it into the Welcome dialog.

   {{{user_0.password | "Password"}}}

   You can also find the Password in the Lab Details pane.

6. Click Next.

   Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.

7. Click through the subsequent pages:

   • Accept the terms and conditions.
   • Do not add recovery options or two-factor authentication (because this is a temporary account).
   • Do not sign up for free trials.

After a few moments, the Google Cloud console opens in this tab.

Note: To access Google Cloud products and services, click the Navigation menu or type the service or product name in the Search field.

Task 1. Review the lab topology

In this task, take a moment to review the diagram of the lab environment. VM-Series firewalls are deployed within a regional managed instance group to secure north/south and east/west traffic for two spoke VPC networks.

Task 2. Secure traffic with VM-Series

In this task, protect a VPC network from internet bound threats by using App-ID™ and Threat Prevention™ on the VM-Series firewall.

Step 1. Secure internet inbound traffic

Internet inbound traffic is distributed by an external TCP/UDP load balancer to the VM-Series untrust interfaces. The VM-Series inspects and translates the traffic to VM A in the spoke 1 VPC.

1. Access the web service on VM A through the external load balancer and VM-Series firewall.

   http://{{{project_0.startup_script.ext_lb_ip|pending}}}
   The request to the web service is successful because the VM-Series is pre-configured to allow web-browsing traffic from the internet to VM A.

2. Access the Jenkins service on VM A by appending :8080 to the external load balancer URL.

   http://{{{project_0.startup_script.ext_lb_ip|pending}}}:8080
   > The request to the Jenkins server fails because the Jenkins application has not been enabled in the VM-Series security policies. Palo Alto Networks firewalls leverage App-ID^TM to identify and enable applications with layer-7 controls.

Step 2. Access the VM-Series

Access the VM-Series UI through the external address attached to its MGT interface.

1. Click Activate Cloud Shell at the top of the Google Cloud console.

   

2. In Cloud Shell, retrieve the EXTERNAL_IP attached to the VM-Series MGT interface.

   gcloud compute instances list \ --filter='tags.items=(vmseries-tutorial)' \ --format='value(EXTERNAL_IP)' 1.2.3.4

3. In a separate browser tab, log into the VM-Series the EXTERNAL_IP (use https).

   Key	Value
   Username
   Password

Step 3. Safely enable applications

Palo Alto Networks App-ID™ enables you to see applications on your network and learn their behavioral characteristics with their relative risk. You can use App-ID™ to enable Jenkins traffic through the VM-Series security policies.

1. On the VM-Series, go to Policies → Security. Click the allowed applications column within the inbound-web security policy.

   

2. Click ADD and search for jenkins. Click OK.

   

3. Click Commit → Commit to apply the changes to the VM-Series configuration.

   

4. Once the commit completes, access the Jenkins service again.

   http://{{{project_0.startup_script.ext_lb_ip|pending}}}:8080
   The Jenkins page resolves because you enabled the jenkins application within the VM-Series security policies.

5. On the VM-Series, go to Monitor → Traffic. Enter the query below to filter for jenkins traffic.

   ( app eq jenkins ) Notice the jenkins application was denied before the jenkins application was added to the inbound-web security policy.
   
   This is because the VM-Series use multiple identification techniques to determine the exact identity of applications traversing your network, including those that try to evade detection by masquerading as legitimate traffic.

Step 4. Secure egress VPC traffic

The VM-Series secures outbound internet traffic from the spoke networks and east-west traffic traversing between spoke networks. All egress traffic from the spoke networks is routed to an internal TCP/UDP load balancer that distributes traffic to the VM-Series trust interfaces for inspection.

1. In Cloud Shell, SSH to VM B in the spoke2 network.

   ssh paloalto@{{{project_0.startup_script.ext_lb_ip|pending}}} Pal0Alt0@123 Just like the jenkins example in the previous step, the SSH session is distributed by the external load balancer. The VM-Series inspects and translates the traffic to VM B

2. From VM B, attempt to download a pseudo malicious file from the internet.

   wget www.eicar.org/download/eicar.com.txt Resolving www.eicar.org (www.eicar.org)... 89.238.73.97, 2a00:1828:1000:2497::2 Connecting to www.eicar.org (www.eicar.org)|89.238.73.97|:80... connected. HTTP request sent, awaiting response... 503 Service Unavailable 2023-04-14 20:16:57 ERROR 503: Service Unavailable. The eicar file is considered safe and is used to test threat prevention capabilities.

3. Generate pseudo malicious traffic from VM B to VM A.

   curl http://10.1.0.10/cgi-bin/../../../..//bin/cat%20/etc/passwd curl -H 'User-Agent: () { :; }; 123.123.123.123:9999' http://10.1.0.10/cgi-bin/test-critical

4. On the VM-Series, go to Monitor → Threat to view the threat logs.

Task 3. Autoscale the VM-Series

Autoscaling enables you to scale the VM-Series protecting your cloud assets while providing high availability through cross-zone redundancy.

The VM-Series firewall publishes native PAN-OS™ metrics to Google Cloud Monitoring. Each metric can be set as an autoscaling parameter within the managed instance group.

Step 1. Review PAN-OS metrics in Cloud Monitoring

The lab creates a custom Cloud Monitoring dashboard that displays several of the VM-Series metrics.

1. In Google Cloud, select Monitoring → Dashboards. Select the dashboard VM-Series Metrics.

   

2. The dashboard displays various PAN-OS metrics from the VM-Series instance group.

   These metrics can be used within the regional managed instance group to scale the VM-Series firewalls.
   
   For example, you can scale VM-Series if Dataplane CPU utilization exceeds 90% for more than 5 minutes.

Step 2. Scaling the VM-Series

The managed instance group created within the lab sets the minimum and the maximum number of VM-Series replicas to 1. Here, modify the minimum and the maximum number of replicas to manually increase the number of running firewalls.

1. In Google Cloud, go to Compute Engine → Instance Groups → vmseries. Click EDIT.

   

2. In the Autoscaling section, modify the min and max number of instances:

   Key	Value
   Minimum number of instances	2
   Maximum number of instances	3

   

3. Click Save.

4. Go to Compute Engine → VM instances. A new firewall should now be deployed.

5. Copy the public IP attached to NIC1 on the new firewall and paste it into a browser tab (use https).

   Key	Value
   Username
   Password

   In production environments, it is recommended to use Panorama. Panorama enables you to scale firewalls horizontally while managing the firewalls as a single entity.

6. On the scaled VM-Series, navigate to Monitor → Traffic. The traffic logs should be populated demonstrating the scaled VM-Series is now processing traffic.

   

Click Check my progress to verify the objective. Autoscale the VM-Series
