Azure Policy Compliance Assessments With Pulumi

Introduction

This guide will demonstrate how to use Pulumi to manage Azure Policy compliance assessments. Azure Policy helps you manage and prevent IT issues by enforcing organizational standards and assessing compliance at scale. With Pulumi, you can define and deploy Azure Policies programmatically, ensuring your resources stay compliant.

Step-by-Step Explanation

Step 1: Set Up Your Pulumi Project

1. Initialize a new Pulumi project if you haven’t already:

   pulumi new azure-typescript
   

2. Configure your Azure credentials by logging in:

   az login
   

Step 2: Define Azure Policy

1. Create a new TypeScript file (e.g., policy.ts) in your Pulumi project.
2. Define the Azure Policy in this file. For example, to enforce a policy that ensures all storage accounts have secure transfer required:

   import * as pulumi from "@pulumi/pulumi";
   import * as azure from "@pulumi/azure";
   
   const policyDefinition = new azure.policy.Definition("secureTransfer", {
       policyType: "Custom",
       mode: "All",
       displayName: "Require secure transfer for storage accounts",
       policyRule: {
           if: {
               field: "type",
               equals: "Microsoft.Storage/storageAccounts"
           },
           then: {
               effect: "deny",
               details: {
                   type: "Microsoft.Storage/storageAccounts",
                   field: "properties.supportsHttpsTrafficOnly",
                   equals: true
               }
           }
       }
   });
   

Step 3: Assign the Policy

1. Assign the policy to a specific scope (e.g., a resource group or subscription):

   const policyAssignment = new azure.policy.Assignment("secureTransferAssignment", {
       policyDefinitionId: policyDefinition.id,
       scope: "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}"
   });
   

Step 4: Deploy the Policy

1. Run pulumi up to deploy the policy to Azure:

   pulumi up
   

Conclusion

By following these steps, you can use Pulumi to manage Azure Policy compliance assessments programmatically. This approach ensures that your Azure resources remain compliant with organizational standards, helping you manage and prevent IT issues at scale. For more information, refer to the Pulumi Azure Policy documentation.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure-native";

// Define the Azure Policy
const policyDefinition = new azure.authorization.PolicyDefinition("secureTransfer", {
    policyType: "Custom",
    mode: "All",
    displayName: "Require secure transfer for storage accounts",
    policyRule: {
        if: {
            field: "type",
            equals: "Microsoft.Storage/storageAccounts",
        },
        then: {
            effect: "deny",
            details: {
                type: "Microsoft.Storage/storageAccounts",
                field: "properties.supportsHttpsTrafficOnly",
                equals: true,
            },
        },
    },
});

// Assign the policy to a specific scope
const policyAssignment = new azure.authorization.PolicyAssignment("secureTransferAssignment", {
    policyDefinitionId: policyDefinition.id,
    scope: "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}",
});
