Azure Governance Visualizer aka AzGovViz

Do you want to get granular insights on your technical Azure Governance implementation? - document it in CSV, HTML, Markdown and JSON? Azure Governance Visualizer is a PowerShell based script that iterates your Azure Tenant´s Management Group hierarchy down to Subscription level. It captures most relevant Azure governance capabilities such as Azure Policy, RBAC and Blueprints and a lot more. From the collected data Azure Governance Visualizer provides visibility on your HierarchyMap, creates a TenantSummary, creates DefinitionInsights and builds granular ScopeInsights on Management Groups and Subscriptions. The technical requirements as well as the required permissions are minimal.

You can run the script either for your Tenant Root Group or any other Management Group.

Mission

"Governance can be a complex thing.."

Challenges:

• Holistic overview on governance implementation
• Connecting the dots

Azure Governance Visualizer is intended to help you to get a holistic overview on your technical Azure Governance implementation by connecting the dots

Trust

How can we trust a 20k lines PowerShell script? Besides assuring that Azure Governance Visualizer will not harm at any intent, you may want to secure yourself. Let´s leverage Azure built-in capabilities such as VM Insights to monitor the Azure Governance Visualizer activity.

Setup a Virtual Machine in Azure, deploy the dependency agent extension and execute Azure Governance Visualizer.

In the Azure Portal navigate to the Virtual Machine, Click on Insights in the Monitoring section and click on Map. All connections that have been established will be shown. Now let´s focus on the process pwsh and review the established connections.

Query for Log Analytics:

VMConnection
| where AgentId =~ '<GUID>'
| where ProcessName =~ 'pwsh'
| summarize by DestinationIp, DestinationPort, RemoteIp, Protocol, Direction, RemoteDnsQuestions, BytesSent, BytesReceived

Integrate PSRule for Azure

Pausing 'PSRule for Azure' integration. Azure Governance Visualizer leveraged the Invoke-PSRule cmdlet, but there are certain resource types where also child resources need to be queried to achieve full rule evaluation.

Let´s use PSRule for Azure and leverage over 260 pre-built rules to validate Azure resources based on the Microsoft Well-Architected Framework (WAF) principles. PSRule for Azure is listed as security monitoring tool in the Microsoft Well-Architected Framework.

Parameter: -DoPSRule (e.g. .\pwsh\AzGovVizParallel.ps1 -DoPSRule) Optional parameters:

• -PSRuleVersion - Define the PSRule..Rules.Azure PowerShell module version, if undefined then 'latest' will be used
• -PSRuleFailedOnly - PSRule for Azure will only report on failed resource (may save some space/noise). (e.g. .\pwsh\AzGovVizParallel.ps1 -DoPSRule -PSRuleFailedOnly)

Outputs:

• HTML (summarized)
  • TenantSummary
  • ScopeInsights
    • Management Group (all resources below that scope)
    • Subscription
• CSV (detailed, per resource)

Stats

In order to better understand the Azure Governance Visualizer usage and to optimize the product accordingly some stats will be ingested to Azure Application Insights. Results of stats analysis may be shared at a later stage.

How/What?

If the script is run in Azure DevOps then the Repository Id and executing principal´s object Id will be used to create an unique identifier. If the script is not run in Azure DevOps then the Tenant Id and executing principal´s object Id will be used to create an unique identifier.

SHA384/512 hashed combination of

• portion of the repositoryId/tenantId
  • if repositoryId/tenantId startsWith a letter then use characters 3-8 (6 characters) of the first GUID´s block, combine them with the third GUID`s block of the principal´s objectId (4 characters), SHA512 hash them as identifier0
  • if repositoryId/tenantId startsWith a number then use characters 7-12 (6 characters) of the last GUID`s block, combine them with the second GUID´s block of the principal´s objectId (4 characters), SHA384 hash them as identifier0
• portion of the executing principal´s objectId
  • if objectId startsWith a letter then use characters 3-8 (6 characters) of the first GUID´ block, combine them with the third GUID´ block of the repositoryId/tenantId (4 characters), SHA512 hash them as identifier1
  • if objectId startsWith a number then use characters 7-12 (6 characters) of the last GUID´ block, combine them with the second GUID´ block of the repositoryId/tenantId (4 characters), SHA384 hash them as identifier1

Combine identifier0 and identifier1

• if objectId startsWith a letter then combine identifiers -> 'identifier0 + identifier1', SHA512 hash them as final identifier and remove dashes (string of 128 characters)
• if objectId startsWith a number then combine identifiers -> 'identifier1 + identifier0', SHA512 hash them as final identifier and remove dashes (string of 128 characters)

To conclude the approach: taking 6 or 4 characters from tenantId/respositoryId and objectId of the executing principal to create a unique identifier, which may not be backward resolveable.

The following data will be ingested to Azure Application Insights:

Azure Defender for Cloud may alert Azure Governance Visualizer resource queries as suspicious activity:

Known issues

Working with Git and Windows cloning from your AzDO repository you may experience the following error:

fatal: cannot create directory at 'output/JSON_...': Filename too long

To work around that issue you may want to enable longpaths support. Note the caveats!

git config --system core.longpaths true

Facts

Disabled Subscriptions and Subscriptions where Quota Id starts with with "AAD_" are being skipped, all others are queried. More information on Subscription Quota Id / Offer numbers: Supported Microsoft Azure offers.

ARM Limits are not acquired programmatically, these are hardcoded. The links used to check related limits are commented in the param section of the script.
