What is Microsoft Entra ID?


Microsoft Entra ID is a comprehensive identity and access management (IAM) solution that provides secure and seamless access to applications and resources for users, devices, and applications across various cloud and on-premises environments. It is a rebranding of Azure Active Directory (Azure AD), announced in May 2022, as part of Microsoft's new Entra product family.

Entra ID is designed to enable organizations to manage user identities, control access to applications, enforce security policies, and streamline authentication across a wide array of services—whether on-premises or in the cloud.

Step-by-Step Breakdown of Microsoft Entra ID (Azure AD)

Step 1: Understanding Key Features of Microsoft Entra ID

  1. Identity Management:

    • User Management: Create, manage, and delete user accounts in the organization. It enables creating both cloud-only users and hybrid users that have both cloud and on-premises resources.
    • Group Management: Create and manage groups for roles, resource access, and more. Groups help in assigning roles or access to a group of users, improving management at scale.
    • Self-Service Capabilities: End-users can update their information (e.g., phone number, address) and reset passwords or manage security settings through the Self-Service Password Reset (SSPR) and Self-Service Group Management.

  2. Authentication and Authorization:

    • Single Sign-On (SSO): Users can access multiple applications with one set of credentials, reducing friction and enhancing security.
    • Multi-Factor Authentication (MFA): A higher level of security that requires additional verification methods (e.g., SMS, app-based push notifications) to access resources.
    • Conditional Access: Policies to enforce MFA, block access, or require other actions based on user risk levels, device compliance, location, and other conditions.
    • Passwordless Authentication: Using biometric data (e.g., Windows Hello), security keys, or the Microsoft Authenticator app for user authentication.

  3. Identity Protection:

    • Risk-Based Conditional Access: Policies to automatically adjust access controls based on the risk level of a user's sign-in behavior or actions.
    • Risk Detection: Detect suspicious activity like impossible travel or sign-ins from unfamiliar locations or devices and take appropriate actions.
    • Risky Sign-Ins and Users: Flags users or sign-ins that pose a potential security risk, allowing administrators to respond swiftly.

  4. Application Management:

    • App Integration: Seamlessly integrate hundreds of third-party SaaS applications (like Salesforce, Google Workspace) and Microsoft services (Office 365, SharePoint) to streamline authentication and authorization.
    • App Proxy: Extend secure access to on-premises applications from any device, enabling remote work while maintaining security controls.
    • Application Provisioning: Automates the user lifecycle process for applications, including automatic user creation, deletion, and updates.

  5. Identity Governance and Administration:

    • Access Reviews: Periodic review of who has access to what applications and data, and the ability to revoke or update access to maintain security and compliance.
    • Entitlement Management: Automate the process of requesting, approving, and granting access to resources based on predefined roles.
    • Privileged Identity Management (PIM): Controls and audits the access of users to critical resources, especially those with administrative privileges, ensuring just-in-time access for administrators.

Step 2: Enabling Microsoft Entra ID in Your Organization

To begin using Microsoft Entra ID, you need to set up and configure your organization’s identity and access management processes. Here's how you can get started:

  1. Sign Up for Microsoft Entra ID:

    • If your organization doesn’t already have an Azure AD instance, you'll need to sign up for Microsoft Entra ID by subscribing to a Microsoft 365 or Azure service.
    • Visit the Microsoft Entra ID page to sign up and start using Entra.

  2. Access the Admin Portal:

    • After signing up, log in to the Microsoft Entra ID admin portal (formerly Azure AD portal) at https://entra.microsoft.com.
    • You can also access the portal via the Azure portal if you are using Azure services.

  3. Add Your Organization's Domain:

    • In the Entra ID portal, go to Azure Active Directory → Custom domain names.
    • Add and verify your organization’s custom domain. This step allows you to manage identities for users in your organization using your custom domain (e.g., @yourdomain.com).

Step 3: Managing Users in Entra ID

  1. Create and Manage Users:

    • Go to Azure Active Directory → Users → New User.
    • You can create:
      • Cloud-only users: Users who exist solely within Microsoft Entra ID.
      • B2B (Business-to-Business) Users: External users who need access to resources in your environment.
      • B2C (Business-to-Consumer) Users: Users from external systems, typically for customer-facing apps.

  2. Assign Roles and Groups:

    • To efficiently manage users, you can create security groups or Microsoft 365 groups and assign them roles for access to various resources.
    • Go to Azure Active Directory → Groups → New Group to create a new group.

  3. Self-Service Management:

    • Entra ID provides self-service capabilities, allowing users to reset their passwords, manage their security info, and access applications without admin intervention.
    • Set up the Self-Service Password Reset (SSPR) by going to Security → Authentication methods → Password reset.

Step 4: Implementing Security Controls

  1. Set Up Multi-Factor Authentication (MFA):

    • In Microsoft Entra ID, go to Security → MFA and enable it for your organization.
    • Choose to enforce MFA for all users or specific groups or applications.
    • You can use the Microsoft Authenticator app, text messages, or phone calls for verification.

  2. Configure Conditional Access Policies:

    • In Azure Active Directory, go to Security → Conditional Access.
    • Set policies that control how and when users can access resources based on conditions such as:
      • User risk level
      • Device compliance
      • Location (e.g., only allowing access from specific geographic regions)
      • Device platform (e.g., only allow access from mobile devices)

  3. Implement Identity Protection:

    • Entra ID helps protect against malicious activities such as impossible travel, unfamiliar sign-ins, and compromised accounts.
    • Go to Security → Identity Protection to set policies that help automatically identify and respond to risky sign-ins and users.

Step 5: Monitoring and Reporting

  1. Monitor Sign-Ins and User Activity:

    • Entra ID provides detailed reports on user sign-ins and activity within your environment.
    • Navigate to Azure Active Directory → Sign-ins to review detailed logs of user sign-ins, including success and failure rates.

  2. Audit Logs:

    • You can review Audit Logs to track changes in user roles, permissions, and configurations within your Entra ID instance. Go to Azure Active Directory → Audit logs.
    • This can help you identify potential misconfigurations or security issues.

  3. Set Up Alerts:

    • Microsoft Entra ID allows you to set up alerts for abnormal activities (e.g., multiple failed logins).
    • Set up alerts by navigating to Security → Alerts in the admin portal.

Step 6: Managing Applications with Entra ID

  1. Single Sign-On (SSO):

    • Entra ID supports SSO for thousands of cloud-based applications, including Microsoft 365, Salesforce, ServiceNow, and more.
    • Go to Azure Active Directory → Enterprise Applications → New Application to configure SSO for third-party apps.

  2. App Proxy:

    • Use the Azure AD Application Proxy to provide remote access to on-premises apps securely.
    • Install the Application Proxy connector on your on-premises network and then configure the app within the Entra ID portal.

  3. Automated Provisioning:

    • Entra ID can automate the user lifecycle for applications, allowing for the automated creation, updates, and deletion of user accounts in connected apps.
    • Set up Provisioning in Azure Active Directory → Enterprise Applications → Provisioning.

Step 7: Advanced Features (Optional)

  1. Hybrid Identity:

    • If your organization uses both on-premises Active Directory and Entra ID, you can synchronize users and groups with Azure AD Connect for a hybrid identity solution.
    • This allows users to seamlessly access both on-premises and cloud resources with a single set of credentials.

  2. External Identities:

    • Entra ID allows you to provide secure access to external users (e.g., business partners, customers) via B2B and B2C scenarios.
    • Configure External Identities under Azure Active Directory → External Identities to manage invitations and permissions for external accounts.

  3. Privileged Identity Management (PIM):

    • PIM helps manage and monitor privileged accounts and access rights.
    • Set up PIM to ensure that admin privileges are granted only when necessary and are subject to approval processes.

Conclusion

Microsoft Entra ID (formerly Azure Active Directory) is a powerful identity and access management solution that allows organizations to securely manage user access to both cloud and on-premises resources. It offers a wide range of features such as user and group management, authentication, security policies, application integration, and advanced identity governance tools. By following the steps above, you can configure, manage, and monitor identities in your organization to ensure secure access, streamline user experience, and protect your resources.
