Introduction to Microsoft Entra ID
What is Entra ID?
Microsoft Entra ID is the new name for what was once called Azure Active Directory (Azure AD). It's a cloud-based service that handles identity and access management for the entire Microsoft ecosystem. Think of it as a central control panel for managing who can access your organization's apps and data.
Microsoft Entra ID (Azure AD) is a cloud-based identity and access management (IAM) service.
At its heart, Entra ID is a directory service. It stores information about users, groups, and devices. But it's much more than just a list. It acts as the gatekeeper, verifying identities and enforcing access policies before letting anyone into your digital resources, whether they're in the cloud or on-premises.
Identity
noun
A set of attributes and characteristics that uniquely describes a person, device, or service within a digital system.
Core Features
Entra ID is packed with features designed to secure and streamline access. While the list is long, a few core capabilities are fundamental to its function.
| Feature | Description |
|---|---|
| Single Sign-On (SSO) | Lets users log in once with a single account to access multiple applications without re-entering their credentials. |
| Multi-Factor Authentication (MFA) | Adds an extra layer of security by requiring users to provide two or more verification methods to prove their identity. |
| Conditional Access | Acts as a rule-based engine that evaluates signals (like user location or device health) to enforce access policies. |
| Role-Based Access Control (RBAC) | Manages who has permission to access specific resources by assigning roles with defined permissions. |
These features work together to create a secure but user-friendly environment. SSO reduces password fatigue for users, while MFA and Conditional Access ensure that only the right people get in, under the right circumstances.
The Central Hub
One of Entra ID's most important roles is its deep integration across Microsoft's cloud services. It's the identity foundation for Microsoft 365, Microsoft Azure, and Dynamics 365. When a user logs into their email on Outlook or accesses a file in SharePoint, Entra ID is working in the background to authenticate them.
This centralization simplifies administration. Instead of managing separate user accounts for every application, you manage one identity for each user in Entra ID. This single source of truth ensures that when an employee leaves the company, their access to all connected services can be revoked from one place.
Ultimately, Entra ID provides the control plane for your entire digital estate, making it the core of modern identity and access management (IAM).
