NOTE: This version of the blog is based on the AIP Classic version of the AIP scanner. If you would like to deploy the Unified Labeling version, please see https://aka.ms/ScannerBlogUL.
Most modern organizations have terabytes (or petabytes) of unstructured data sitting in their on-premises data repositories and SharePoint libraries. Managing this data the way you manage other corporate resources is a daunting but achievable task using tools that you likely already own. In this article, we will walk you through the discovery of sensitive data and show you options to classify and protect that data.
The AIP scanner allows you to scan your on premises data repositories against the standard Office 365 sensitive information types and custom types you build with keywords or regular expressions. Once the data is discovered, the AIP scanner(s) can aggregate the findings and display them in Analytics reports so you can begin visualizing your data risk and see recommendations for setting up protection rules based on the content.
To configure the scanner, there are a few steps you need to follow:
Now, this may seem like a lot of things, but don't worry. We will walk you through the whole process so that it is as painless as possible. However, before production deployment we recommend that you read through the official documentation at https://docs.microsoft.com/en-us/azure/information-protection/deploy-aip-scanner to ensure that you will not run into any issues.
Installing the AIP scanner binaries is a very straight-forward process as they are included with the AIP client. Navigate to https://aka.ms/AIPClient and click the Download button. When presented with the download options, check the box next to AzInfoProtection.exe (NOTE: The AzInfoProtection_ul.exe client does NOT contain the Scanner binaries in the current version) and click the Next button. The download should start automatically. Once complete, double-click on the file and run through the quick setup on the prepared AIP scanner server.
We must create Azure AD Applications for AIP Authentication to allow the scanner to protect files non-interactively (you only need to run these the first time you are setting up the AIP scanner. You can use the same command created at the end to authenticate multiple AIP scanner servers). The official documentation for creating these applications is found here.
For convenience, we have created an example named New-AIPAuthToken.ps1 which you may review and download from https://aka.ms/MIPFiles/Scripts. This will create a file named Set-AIPAuthentication.txt on the desktop that will contain the command needed to authenticate your AIP scanner server(s).
Although this step is technically optional, we recommend configuring analytics prior to running your first scan so you can begin to visualize your data risk as shown in the initial image in this article. In the AIP blade of the Azure Portal, you will see Configure analytics (preview) under the Manage section. Click on this and you should see a page like the one below.
If you already have a configured ALA Workspace for this purpose, check the box next to it and press OK. Otherwise, click the + Create new workspace link.
Fill in the items shown in the image below:
Finally, back in the Configure analytics (preview) blade, check the box next to the workspace and click OK.
NOTE: Checking the box next to Enable deeper analytics allows the actual matched content to be stored in the Log Analytics workspace. This could include many types of sensitive information such as PII, Credit Card Numbers, and Banking Information. This option is typically used during testing of automatic conditions and not widely used in production settings due to the sensitive nature of the collected data. If this is used in a production setting, extreme caution should be taken with securing access to this workspace.
As introduced in our previous blog post, configuration of the AIP scanner is now done via the Central Management User Interface in the Azure Portal. The PowerShell configuration commands for AIP scanner will be deprecated. We will quickly walk through the minimum configuration elements to install a functional scanner in discover mode.
The AIP scanner Profiles (Preview) blade can be found in the AIP blade on the left side in the Scanner section. Follow the steps below to create and configure an AIP scanner profile.
There are many other options and settings for the Scanner profiles and we will dive into those further in another blog post. If you would like more information today, please see our official documentation.
We should now have all prerequisites in place to install the AIP scanner. To do this, type the command below in an Administrative PowerShell window.
Install-AIPScanner -Profile "ProfileName"
You will be prompted to enter the local AIP scanner service account credentials in Domain\AccountName format and to provide the SQL Server instance name (This will be ServerName or ServerName\SQLExpress depending on the version you installed).
If you encounter any errors, please validate that the installer account has the permissions mentioned in the On-Premises Prerequisites and you do not have any firewall issues reaching the SQL server or Azure.
Now that you have the AIP scanner service installed, you can run the Set-AIPAuthentication command to get the non-interactive authentication token.
In the Admin PowerShell prompt, run the code below to run the Set-AIPAuthentication command. This will ask for the credentials of the on-premises AIP scanner service account. The service is then restarted to allow it to use the new token and pull down policy.
$scannercred = Get-Credential $AuthCommand = Get-Content ~\Desktop\Set-AIPAuthentication.txt Start-Process powershell.exe -Credential $scannercred -NoNewWindow -ArgumentList $AuthCommand Restart-Service AIPScanner
This command can be modified to point to the txt file in other locations if needed for use on future instances of the AIP scanner. The same Set-AIPAuthentication command can be used on multiple servers in your tenant even if they use different profiles.
The scanner should be fully functional at this point and you can run the commands below to verify the state (should be idle) and start the initial discovery scan.
Get-AIPScannerStatus Start-AIPScan
After a few minutes you will begin seeing data start to flow into your Data discovery (Preview) dashboard in the azure portal. Since you are only doing discovery, you will not see any labeled or protected files (unless you have been using AIP before running the scanner), but you will see the identified files and the sensitive data types found in the configured repositories.
The is also a new blade under Analytics named Recommendations (Preview) that will be populated by this data. Any sensitive information types discovered that do not have associated automatic classification conditions will display in this blade.
You may then click on the sensitive information type and a fly-out panel will allow you to assign the information type to a classification label. This allows you to quickly map your sensitive information to classification labels.
NOTE: The AIP scanner will only trigger on conditions which are set to Automatic.
Once you have configured these conditions, you can return to the profile in the Azure portal and change the settings to the ones below.
Because we set the schedule to Always, the scanner will begin monitoring the files automatically within 5 minutes. If you want to start the scan yourself, follow the instructions below.
The result will be similar to the image shown below with labeled and protected files and the distribution graph showing in the Data discovery (Preview) dashboard.
Please let us know in the comments if you have any questions on this approach. If you are interested in how Microsoft uses the AIP scanner, please see the MSIT showcase at https://aka.ms/ScannerShowcase.
