Overview

In this lab, you wil learn how to use the Sensitive Data Protection plugin for Cloud Fusion to redact sensitive data.

Consider the following scenario, in which some sensitive customer information needs to be redacted.

Scenario: Your support team documents the details of each support case they handle in a support ticket. All of the information in the support tickets is pulled into a CSV file. The support technicians are not supposed to document any customer information that's considered sensitive, but sometimes they mistakenly do so. You notice that in the CSV file some customers' phone numbers appear.

You want to go through the CSV file and hide all phone numbers. You create a Cloud Data Fusion pipeline that redacts the sensitive customer data by using the Sensitive Data Protection plugin.

You will create a pipeline that does the following:

• Redacts customer phone numbers and emails by masking them with the # character.
• Stores the masked sensitive data and the non-sensitive data in a Cloud Storage.

Objectives

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

• Connect Cloud Data Fusion to a Cloud Storage source.
• Deploy the Sensitive Data Protection plugin.
• Create a custom Sensitive Data Protection template.
• Use the Redact transform plugin to mask sensitive customer data.
• Write the output data to Cloud Storage.

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 Google Cloud Skills Boost using an incognito window.

2. Note the lab's access time (for example, 02:00:00), 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.

   Note: Once you click Start lab, it will take about 15 - 20 minutes for the lab to provision necessary resources and create a Data Fusion instance. During that time, you can read through the steps below to get familiar with the goals of the lab.
   When you see lab credentials (Username and Password) in the left panel, the instance is created and you can continue logging into the console.

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.
