Types of Azure AD Identities
Azure AD identities consist of the following types:
- Cloud Identities: These are accounts that exist only in Azure AD and are not synchronized with any on-premises directory. They are ideal for small organizations without on-premises servers or for users who only need access to cloud resources.
- Synced Identities: Also known as directory synchronized identities, these are synchronized from an on-premises Active Directory to Azure AD using tools like Azure AD Connect. This is beneficial for organizations that have existing on-premises AD environments and want a consistent identity for users both on-premises and in the cloud.
- Federated Identities: This model involves configuration of federation services (like AD FS) to enable users to authenticate using on-premises credentials. Federated identities are a good option for organizations with strong requirements for on-premises authentication or complex multi-forest environments.
Example of Identity Planning:
An organization, Contoso Ltd., with a mix of cloud services and on-premises applications, might plan to use a combination of identity types:
- Office and field staff who require access to cloud resources like Office 365, as well as on-premises applications, would be best served with Synced Identities using Azure AD Connect.
- Temporary staff or contractors might be assigned Cloud Identities as they only need short-term access to certain cloud-based applications.
Choosing an Authentication Method
When you plan Azure AD identities, you also need to choose the appropriate authentication method. This could range from password hash synchronization, pass-through authentication, to federated authentication. Here’s a brief comparison:
| Authentication Method | Description | Use Case |
|---|---|---|
| Password Hash Synchronization | The hash of the on-premises AD password hash is synchronized to Azure AD. | Organizations looking for a simple cloud identity solution with an on-premises AD. |
| Pass-through Authentication | Allows users to authenticate directly to the on-premises AD while still accessing cloud resources. | Organizations that want a simple solution without needing complex federation infrastructure but with on-premises AD authentication. |
| Federated Authentication | Users authenticate to the on-premises AD, but this is brokered through a federation service like AD FS. | Organizations with complex AD environments, or those requiring advanced security features like smart card or third-party multi-factor authentication (MFA). |
Azure AD Connect
Azure AD Connect is the tool of choice for synchronizing on-premises identities to Azure AD. It provides features like:
- Synchronization of user accounts, group memberships, and credentials.
- Various sign-in options, including password hash synchronization and pass-through authentication.
- Support for hybrid environments with the synchronization of AD FS for federated authentication.
Example of Azure AD Connect Setup:
In deploying Azure AD Connect, Contoso Ltd. decides to use password hash synchronization to minimize on-premises infrastructure requirements. This method allows users to have the same password on-premises and in the cloud, with the security of not storing the actual password in Azure AD.
Managing Azure AD Identities
Managing identities involves not just the initial deployment but also ongoing administration. Key tasks include:
- Ensuring user attributes are accurately synchronized.
- Handling joiners, movers, and leavers by automating account provisioning and deprovisioning.
- Integrating multi-factor authentication for additional security.
Governance and Compliance
Lastly, governance and compliance considerations are essential. This involves:
- Defining clear policies for access and identity lifecycle management.
- Monitoring and auditing access to ensure compliance with regulatory requirements.
- Implementing Privileged Identity Management (PIM) to manage, control, and monitor access within Azure AD.
In conclusion, carefully planning Azure AD identities is critical for the secure and efficient operation of any organization’s cloud and on-premises resources. By understanding the different types of identities and selecting appropriate authentication methods, organizations can ensure that they have a robust identity strategy that aligns with their IT infrastructure and business requirements.
