Introduction to Google Cloud Platform
Part 0: Choose a Google account
In this tutorial, you will use a Google account to sign up for Google Cloud Platform (GCP). You will also join a Google Group with this account, which will give you access to certain GCP resources.
Choose a Google account you will use. You have several options:
- You can use a personal Google account that you already have
- You can create a new personal Google account by signing up for one here
- If you have a non-
@gmail.comgoogle account (perhaps through your university), it won’t work for GCP unless the domain admin has enabled creation of GCP resources by your account. For example,
@temple.eduGCP accounts will not be able to create projects on GCP. If this is the case, use a personal Google account.
Regardless, whenever you use GCP, be sure that you are accessing the platform while signed in to the correct Google account. Otherwise, you may be confused to not see expected projects or to get “access denied” messages.
Part 1: Sign up for Google Cloud Platform (GCP)
- Visit https://cloud.google.com and click “Get started for free.”
- Make sure you are signed in to Google with the account you want to use with GCP.
- Step 1 of 2: Agree to the terms of service.
Step 2 of 2: Choose “Account type” > “Individual”. Complete the sign-up form. Provide a credit card.Why a credit card? Google still requires a credit card to make sure you are not a robot. Google will not autocharge your account unless you manually upgrade to a paid plan.
- Click “Start my free trial”.
Part 2: Join the infosec-management Google Group
To get access to the Google Cloud Platform virtual machines created for the labs on this site, visit the storefront and follow instructions there to purchase access to the “lab virtual machine access package”. This will give your gcp email address access to certain Kali GCP images used for this class.
Part 3: Create a new project and launch a new Kali Linux instance
Once you have purchased access and your gcp email address has been added to the infosec-management google group, do the following:
- First, create a new “project” which will house all of the material for this class.
- Click “create project”
- Choose a name for your project, and for the “Location,” choose “No Organization”.
- Then, expand the hamburger menu and navigate to the “Compute Engine” area. Click to enable. Wait a few minutes for Compute Engine to set up.
- Click “Enable.”
- Click “Create Instance”.
- Use the following settings or the first set of options:
- In the “name” field, enter any name for your instance, such as “kali”.
- Set the “Region” field to “us-central1”. The “Zone” can be anything within that zone.
- Set the “Series” field set to “N1”
- Change the “Machine type” field to “n1-standard-4 (4 vCPU, 15 GB memory)”
- For the “CPU platform” field:
- Click the “CPU platform and GPU” dropdown to expand this menu section
- Select “Intel Haswell or later”.
- Use the following settings for the “Boot disk” field:
- Click “Change”.
- Select the “Custom images” tab.
- Click “Select a Project.” Click the “All” tab to see all projects. Choose “security-assignments-kali”.
- Select the most recent Kali version that you see.
- Set “Boot disk type” to “Standard persistent disk”
Under the “Size (GB)” field, you can choose a value between 500GB (the image size) and 1,000GB (the quota limit for new accounts).
The labs don’t require anywhere near even 500GB disk space, but with cloud computing, the more space that you allocate for your drive, the better performance they give to read/write operations for your instance.
Click the “Create” button.
- Wait a few minutes for your image to boot.
- Once it does, it will show a checkmark.
Connect to your instance via
ssh. If it fails to connect, try again (the system may not have finished booting).
You should see a browser window pop up that looks like the following image. Leave this popup open – you will need it for the next step.
Part 4: Connect to your Kali Linux VM using Chrome Remote Desktop
Setting up Chrome Remote Desktop (CRD) will enable you to graphically connect to your Kali instance, from your browser, using a Google account to sign in. You should be able to log in as long as your Kali instance is running on GCP.
- Open another browser window, and visit https://remotedesktop.google.com/headless.
- Click the “Begin” button.
- Click the “Next” button. (Chrome Remote Desktop is already installed on Kali).
- Click the “Authorize” button.
- Select your personal Google account and click the “Allow” button.
Click the icon to the right of the Debian Linux command to copy the command:
- Switch to your browser window with the ssh connection to Kali, paste in the command you copied into the Kali Linux command line. Press
- Enter and re-enter a six-digit pin. Press enter.
Did you get an OAuth error? This may happen if something went wrong when you ran the command copied , and if you tried to run it again. The copied command is only valid for one attempt. You will need to start this section over again, to obtain another authorization url, which will have a new auth token embedded.
- You will not see any visual feedback as you enter a pin. This is normal.
Switch back to the window with remotedesktop.google.com open. Click the “Remote Access” link at the top or visit https://remotedesktop.google.com/access.
Click on your Kali instance.
Type in your six-digit pin, and check the box so that your browser remembers the pin.Can't get to the pin-entry screen? Try a different web browser, such as Google Chrome. Also try disabling any browser extensions that may be interfering.
Next, if you are prompted to enter a password to create a “color managed device”, type in the password
toor, and click
After you finish logging in, you should see a screen like the following:
Note that if you click the blue arrow tab on the right hand of the screen, it opens additional options in Chrome Remote Desktop. Take this opportunity to enable copy-paste across your remote desktop session.
Part 5: Set up budget alerts
You get $300 in free credits when you sign up for google cloud platform. As of 8/27/2019, the Kali instance that you launch will cost almost $200 per month if you run it continuously. So do not run it continuously. Shut down the instance when you are not using it. You are only billed by GCP for time that your instance is running.
You can either suspend, shut down, or delete an instance. Which you choose will depend on your needs, but be aware that suspended instances still incur some costs.
The semester is about four months long, so set up a budget planning to spend (no more than) $75 per month. To do so:
- Click the hamburger menu on the upper left >
Budgets & alerts.
(1) Scope> Projects => “All projects”
Budget type=> “Specified amount”,
Target amount=> $75, uncheck “Include credits in cost.”
(3) Actions> Set four thresholds – one for each week of the month – at 25%, 50%, 75%, and 100%. When you have hit these thresholds within a month, you will receive a budget notificaiton email.
These budget reminders will help you to keep an eye on your costs, and will help remind you to shut down an instance that could otherwise cost you a lot of money.
Part 6: Install a GCP Console app on a mobile device
You can manage your GCP instances from the Cloud Console Mobile App. This can be handy if you realize that you have accidentally left an instance running – you can easily shut it down from the app.
Part 7: Complete the Introduction to Linux Tutorial
Complete this introduction to Linux tutorial. Then, come back and complete the deliverable for this tutorial.
Using the Kali VM for the steps below shows both that you got your Kali VM up and running, and that you have basic skills with the Linux terminal. You must use your Kali GCP instance for the following.
- Using a terminal,
- make a directory called
- In that directory, create a file called
i-did-it.txtwith the following contents:
- make a directory called
- Submit a screenshot showing:
- The browser tab address showing that you are connected via chrome remote desktop to your kali instance
- The terrifying kali dragon desktop
- A terminal window, showing:
