How to use PowerShell to navigate the IAM infrastructure

PowerShell can be used to navigate and manage identity and access management (IAM) infrastructure in Microsoft Entra ID and Microsoft 365 by using dedicated PowerShell modules and cmdlets. For provisioning and deprovisioning, the key tasks are connecting securely, creating and managing users and groups, assigning roles, and managing licenses.

A practical approach is:

1. Learn core PowerShell skills
   Before working with IAM, become comfortable with PowerShell basics: running commands, using the pipeline, discovering cmdlets, and writing simple scripts. The learning paths and modules below cover:
   • What PowerShell is and how to run commands and scripts.
   • How to discover commands (Get-Command, Get-Help) and inspect output.
   • How to connect commands into pipelines and build reusable scripts for automation.
2. Use Microsoft Entra / Microsoft 365 PowerShell for IAM
   For IAM provisioning and deprovisioning, use the Microsoft Entra and Microsoft 365–focused modules and cmdlets described in these modules:
   • Manage Microsoft Entra identities / Manage identities in Microsoft Entra ID:
     These modules show how to:
     • Create and manage users in Microsoft Entra ID (for provisioning and deprovisioning accounts).
     • Create and manage groups (for access control and role-based access).
     • Use Windows PowerShell or Microsoft Graph PowerShell cmdlets to manage Entra objects.
     • Work with RBAC and user roles in Microsoft Entra ID so that access is granted via role assignments rather than direct permissions.
   • Manage users, groups, roles, and licenses in Microsoft 365 with PowerShell:
     This module focuses on:
     • Connecting to a Microsoft 365 tenant with PowerShell.
     • Creating and managing users and groups.
     • Managing roles (for example, assigning admin roles to security engineers or application owners).
     • Managing licenses, which is a key part of provisioning/deprovisioning access to services.
   In practice, the workflow for IAM with PowerShell is:
   • Connect to Microsoft Entra ID / Microsoft 365 using the appropriate module.
   • For provisioning: create the user object, add it to the correct groups, assign roles, and assign licenses.
   • For deprovisioning: remove or disable the user, remove group memberships, revoke roles, and remove or reassign licenses.
3. Use Azure PowerShell for resource-level IAM (RBAC)
   When IAM includes Azure resource access (for example, assigning roles on subscriptions, resource groups, or specific resources), use Azure PowerShell (Az module):
   • The Review Azure PowerShell module explains Azure PowerShell and the Az module, and how to install and use it.
   • Once connected, RBAC assignments can be managed via Az cmdlets (for example, assigning built-in roles to users or groups at different scopes).
     This lets security engineers automate access control for Azure resources as part of provisioning and deprovisioning workflows.
4. Automate and operationalize IAM tasks
   After learning the cmdlets, use scripting modules to:
   • Write scripts that encapsulate the provisioning and deprovisioning process (input: user attributes; output: created user, group memberships, roles, licenses).
   • Integrate these scripts into CI/CD or operational tooling so that IAM changes are consistent and auditable.
5. Extend to Microsoft 365 security and management
   The Security and Management Open PowerShell module provides commands for managing aspects of Microsoft 365, such as device registration with Intune. These can be combined with identity provisioning scripts to ensure that user and device onboarding/offboarding are aligned.

By combining the PowerShell fundamentals learning paths with the Entra ID and Microsoft 365–specific modules, security engineers can reliably navigate IAM infrastructure and automate provisioning and deprovisioning using scripts and pipelines.
