Overview

Gemini for Google Cloud is an always-on AI collaborator that provides help to users of all skill levels where they need it. In this lab, you will learn how to identify and remediate security misconfigurations in your Google Cloud environment using Security Command Center's Gemini features.

Note: Duet AI was renamed to Gemini, our next-generation model. This lab has been updated to reflect this change. Any references to Duet AI in the user interface or documentation should be treated as equivalent to Gemini while following the lab instructions. Note: As an early-stage technology, Gemini can generate output that seems plausible but is factually incorrect. We recommend that you validate all output from Gemini before you use it. For more information, see Gemini for Google Cloud and responsible AI.

Objectives

In this lab, you will learn how to perform the following tasks:

  • Enable Gemini in a Google Cloud project
  • Deploy example workloads into an environment in Google Cloud
  • Identify security misconfigurations with Gemini
  • Remediate security misconfigurations with Gemini

Scenario

As you monitor your infrastructure for ways to improve your security posture, Gemini can help identify infrastructure or configuration changes that will prevent issues in the future.

In this example, consider that you are a security engineer at an ecommerce company where managed Kubernetes clusters are regularly deployed. You need a way to see if there are any misconfigurations, and you want quick instructions to help fix those issues in your cloud environment.

Setup and requirements

For each lab, you get a new Google Cloud project and set of resources for a fixed time at no cost.

  1. Sign in to Qwiklabs using an incognito window.

  2. Note the lab's access time (for example, 1:15:00), and make sure you can finish within that time.
    There is no pause feature. You can restart if needed, but you have to start at the beginning.

  3. When ready, click Start lab.

  4. Note your lab credentials (Username and Password). You will use them to sign in to the Google Cloud Console.

  5. Click Open Google Console.

  6. Click Use another account and copy/paste credentials for this lab into the prompts.
    If you use other credentials, you'll receive errors or incur charges.

  7. Accept the terms and skip the recovery resource page.

Task 1. Enable Gemini

You will first enable Gemini in your Google Cloud project and configure the necessary permissions for your Google Cloud Qwiklabs user account.

  1. Click on the Cloud Shell icon (Cloud Shell icon) in the top-right corner of the Google Cloud console toolbar.

  2. To set your project ID and region environment variables, run the following commands:

PROJECT_ID=$(gcloud config get-value project) REGION={{{project_0.default_region|lab region}}} echo "PROJECT_ID=${PROJECT_ID}" echo "REGION=${REGION}"
  1. To store the signed-in Google user account in an environment variable, run the following command:
USER=$(gcloud config get-value account 2> /dev/null) echo "USER=${USER}"
  1. Click Authorize if prompted.

  2. Enable the Cloud AI Companion API for Gemini:

gcloud services enable cloudaicompanion.googleapis.com --project ${PROJECT_ID}
  1. To use Gemini, grant the necessary IAM roles to your Google Cloud Qwiklabs user account:
gcloud projects add-iam-policy-binding ${PROJECT_ID} --member user:${USER} --role=roles/cloudaicompanion.user gcloud projects add-iam-policy-binding ${PROJECT_ID} --member user:${USER} --role=roles/serviceusage.serviceUsageViewer

Adding these roles lets the user use Gemini assistance.

Task 2. Create a GKE cluster and deploy a web app

You will now be creating a Google Kubernetes Engine (GKE) cluster running a handful of microservices.

  1. Run the following command to create a GKE cluster named test:
gcloud container clusters create test --region={{{project_0.default_region|lab region}}} --num-nodes=1

This should take a few minutes. Upon completion, you should see a result similar to the following:

Creating cluster test in {{{project_0.default_region|lab region}}}... Cluster is being health-checked (master is healthy)...done. Created [https://container.googleapis.com/v1/projects/agmsb-gke-lab/zones/us-central1/clusters/test]. To inspect the contents of your cluster, go to: https://console.cloud.google.com/kubernetes/workload_/gcloud/us-central1/test?project=agmsb-gke-lab kubeconfig entry generated for test. NAME: test LOCATION: {{{project_0.default_region|lab region}}} MASTER_VERSION: 1.27.3-gke.100 MASTER_IP: 34.66.224.143 MACHINE_TYPE: e2-medium NODE_VERSION: 1.27.3-gke.100 NUM_NODES: 3 STATUS: RUNNING
  1. Now, clone a repository that contains code for a web app:
git clone https://github.com/GoogleCloudPlatform/microservices-demo && cd microservices-demo
  1. Use kubectl to deploy a set of microservices to the GKE cluster:
kubectl apply -f ./release/kubernetes-manifests.yaml
  1. After a couple minutes, run the following command to get the public IP address to access your web app in a browser:
kubectl get service frontend-external | awk '{print $4}'
  1. Copy the IP address from the output of the above command and paste it into a new browser tab.

You should see a web app similar to the following:

Task 3. Identify security misconfigurations with Gemini

Now that you have an existing GKE cluster running an ecommerce app, you will identify areas where you can improve your security posture with Gemini.

  1. Return to your tab with the Google Cloud console.

  2. Refresh the Google Cloud console page.

  3. Minimize the Cloud Shell pane.

  4. Click on the Gemini icon (Gemini icon) in the top-right corner of the Google Cloud console toolbar.

  5. Click Start Chatting.

  6. Enter the following prompt:

What services in Google Cloud can help me identify areas to improve security for a set of microservices running in a GKE cluster?

Gemini should respond with something similar to the following:

There are a number of services in Google Cloud that can help you identify areas to improve security for a set of microservices running in a GKE cluster. These include:

  • Security Command Center can help you identify and prioritize security risks across your Google Cloud environment, including GKE clusters.
  • Cloud Asset Inventory can help you track and manage your Google Cloud resources, including GKE clusters.
  • Cloud Logging can help you collect and analyze logs from your GKE clusters.
  • Cloud Monitoring can help you monitor the performance and health of your GKE clusters.
These are just a few of the many services in Google Cloud that can help you improve the security of your microservices. By using these services, you can help protect your data from unauthorized access, and you can also help improve your security posture over time.

In this scenario, you decide that Security Command Center sounds like the right place to start.

  1. Open the Navigation menu and select Security > Risk Overview.

With multiple visualizations discussing vulnerabilities, you want to ask Gemini to help you quickly understand what is classified as a vulnerability in Security Command Center.

  1. Enter the following prompt:
How does Security Command Center define a vulnerability?

Gemini's response should be similar to the following:

Security Command Center defines a vulnerability as a flaw or weakness in software programs that an attacker could use to gain access to or otherwise compromise your Google Cloud environment.

  1. Exit out of this information panel.

  2. Next, click on the Over privileged account finding and view the summary in the description which is similar to the following:

This GKE node uses the Compute Engine default service node, which has broad access by default and may be over privileged for running your Kubernetes Engine cluster....
  1. Exit out of this information panel.

  2. Finally, click on the Master authorized networks disabled finding. You should see a description similar to the following:

Control plane authorized networks improve security for your container cluster by blocking specified IP addresses from accessing your cluster's control plane...
  1. Exit out of this information panel.

Now that you have an understanding of some of your environment's security misconfigurations, you will leverage Gemini's recommendations to remediate them.

Task 4. Remediate a security misconfiguration

Now that you have had the opportunity to review multiple areas to begin improving the security of your GKE cluster, you will remediate the "Master authorized networks disabled" finding using the instructions provided by Gemini's summary in Security Command Center.

  1. Open the Navigation menu and select Kubernetes Engine > Clusters.

  2. Click the name of the cluster you created earlier ("test").

  3. Scroll down to the Networking section.
