Plan and Implement Workload Identities

Plan and Implement Workload Identities refers to the process of managing non-human identities in Microsoft Entra ID (formerly Azure AD) that are used by applications, services, and automated processes to access resources. **What Are Workload Identities?** Workload identities represent software workloads such as applications, service principals, and managed identities. Unlike user identities, these are used by applications and services to authenticate and access Azure resources programmatically. **Key Components:** 1. **Application Registrations:** Creating app objects in Microsoft Entra ID that define the application's identity configuration, including permissions, credentials, and authentication settings. 2. **Service Principals:** The local representation of an application object in a specific tenant, defining what the app can do within that tenant, who can access it, and what resources it can reach. 3. **Managed Identities:** Azure-managed identities that eliminate the need to store credentials in code. They come in two types - System-assigned (tied to a resource lifecycle) and User-assigned (standalone, reusable across multiple resources). **Planning Considerations:** - Determine which workloads need identities and appropriate identity types - Apply least-privilege access principles using role-based access control (RBAC) - Implement credential management policies including certificate rotation and secret expiration - Use Conditional Access policies for workload identities to enforce location and risk-based controls - Monitor and audit workload identity activities through sign-in logs **Implementation Best Practices:** - Prefer managed identities over service principals to avoid credential management overhead - Implement workload identity federation for external systems to avoid storing secrets - Use Workload Identity Premium features for Conditional Access and identity protection - Regularly review and remove unused application registrations and service principals - Configure app governance policies to detect anomalous behavior **Security Measures:** - Enable workload identity risk detection through Identity Protection - Implement access reviews for service principals - Use certificates instead of client secrets when managed identities aren't possible Proper planning ensures secure, scalable, and manageable workload identities across your organization.
