What is Azure Active Directory?  

Azure Active Directory (AD) is a service hosted in the cloud that manages identity and access. It includes a directory (database) that records user identities and their respective permissions. This service allows employees to authenticate their identities and access IT resources based on their authorisation levels. 

These resources can be internal, such as data and tools on your company’s intranet, or external, like Microsoft 365 and various Software as a Service (SaaS) applications. 

It’s crucial to note that Azure Active Directory is not merely an instance of Active Directory running on Microsoft’s servers as opposed to your own on-premises data centre. 

It is a distinct solution that forms part of the Microsoft Azure public cloud computing platform. However, on-premises Active Directory and Azure AD can and often do operate in tandem, creating what is known as a hybrid AD environment.

The key features of Azure AD include: 

a) Central repository for user identities: Azure AD is a central repository where user identities are securely stored. Organisations can efficiently manage access to applications and resources across the Azure cloud environment.  

b) Authentication methods: Azure AD supports a range of authentication methods, from traditional usernames and passwords to more robust options like Multi-factor Authentication. Additionally, it integrates with social identity providers such as Facebook, Google, and LinkedIn.  

c) Integration with Microsoft products and services: Azure AD seamlessly integrates with other Microsoft offerings, including Office 365 and Azure. It also extends its capabilities to third-party applications and services.

How does Azure Active Directory work?  

Azure Active Directory (Azure AD) is a purpose-built system by Microsoft, designed specifically to support cloud infrastructure. Unlike its predecessor, Windows Active Directory (AD), which primarily caters to on-premises environments, Azure AD focuses on managing user access to cloud applications and services. 

Let’s explore the details:

How Does Azure Active Directory Work

1) Flat structure and single tenant: Azure AD operates within a flat structure, encompassing a single tenant. Imagine this tenant as a circle that surrounds all your cloud resources. It simplifies management by providing a centralised directory for users, permissions, passwords, and more. 

2) Methods for populating users and groups

a) Azure AD Connect: This method syncs users from Windows to Azure AD. Enterprises already using Windows AD often adopt this approach. 

b) Manual creation: You can create Azure AD Management Portal users.  

c) Scripting and programming: Add new users programmatically using PowerShell or the Azure AD Graph API. 

3) Key considerations for adding users

a) Authentication and security: Establish authentication methods and password policies and enforce multi-factor authentication.  

b) Selective user addition: Only add necessary users to Azure AD. Leave service accounts or outdated accounts in Windows AD or delete them. 

c) Privileged access control: Limit privileged access in Azure AD, following Microsoft’s security guidelines. 

d) Group organisation: Organise users into groups, granting them access only to the applications and resources relevant to their roles. 

e) Device connectivity: Connect users’ devices (mobile phones, laptops, etc.) to establish data download and storage limits. 

4) Custom domains: To enhance User Experience during migration, consider adding a custom domain to Azure AD. The default Azure AD domain (e.g., @notarealdomain.onmicrosoft.com) can be cumbersome. Configuring a domain you own (e.g., @notarealdomain.com) will simplify user interactions.  

Features of Azure Active Directory   

Azure Active Directory (Azure AD) is a cloud-based service that empowers businesses to control user access to applications and resources. Azure AD ensures data security while providing efficient employee access by enforcing security regulations, mitigating risks, and enhancing user experience.  

Let’s explore the key features of Azure AD:

Features of Azure Active Directory

1) Single Sign-On (SSO)

a) Azure AD supports SSO, enabling users to access several applications and resources using a single set of credentials.  

b) This streamlines the login process and enhances the overall user experience. 

2) Multi-Factor Authentication (MFA)

a) MFA provides an additional layer of security. Users can verify their identity through text messages or mobile app notifications before granting access.  

b) It safeguards against unauthorised access and strengthens user authentication. 

3) Azure AD Connect

a) Organisations can synchronise user accounts and passwords between Azure AD and on-premises Active Directory using Azure AD Connect. 

b) This feature enables using single credentials for both on-premises and cloud resources without interruption.  

4) Reporting and Auditing

a)  Azure AD provides robust reporting and auditing features. 

b) Administrators can monitor user behaviour, track changes to user accounts, and manage permissions effectively. 

c) Compliance with legal requirements becomes more manageable, and potential security issues are promptly identified. 

5) Conditional Access

a) Administrators can create access policies based on particular conditions (such as location or device type).  

b) This feature ensures that security policies are enforced, protecting against potential threats. 

6) Application Management

a) Azure AD allows administrators to handle user access to both on-premises and cloud-based applications. 

b) Efficiently managing application access and executing safety policies provide a secure environment.  

Azure AD vs Windows AD
