Introduction
Identity is the foundation of security in any cloud environment. For organizations with existing on-premises Active Directory deployments, transitioning to cloud identity management requires a hybrid approach that bridges on-premises and Azure Active Directory. This guide explains hybrid identity architecture and how to implement it securely and effectively with guidance from Ozy Solutions.
What Is Azure Active Directory?
Azure Active Directory (Azure AD, now called Microsoft Entra ID) is Microsoft’s cloud-based identity and access management service. It provides single sign-on (SSO) for thousands of cloud applications, multi-factor authentication, conditional access policies, and identity governance capabilities. For organizations already running on-premises Active Directory, Azure AD extends and enhances your existing identity infrastructure rather than replacing it.
Azure AD Connect: Bridging On-Premises and Cloud Identity
Azure AD Connect is the tool that synchronizes on-premises Active Directory identities to Azure AD. Once configured, users can sign in to both on-premises and cloud applications with the same credentials. Password hash synchronization, pass-through authentication, and federation with Active Directory Federation Services (ADFS) are the three authentication options, each with different security and complexity tradeoffs.
Implementing Conditional Access Policies
Conditional Access is Azure AD’s powerful policy engine that evaluates signals — user identity, device compliance, location, and application sensitivity — and enforces access controls in real time. Policies can require MFA for risky sign-ins, block access from non-compliant devices, and restrict access to sensitive applications from outside corporate networks. Well-designed conditional access policies dramatically reduce identity-based security risk.
Privileged Identity Management for Hybrid Environments
Privileged Identity Management (PIM) provides just-in-time privileged access to Azure AD and Azure resources. Instead of users having permanent administrative roles that represent a constant attack surface, PIM enables time-limited elevation to privileged roles on demand with approval workflows and audit trails. Extending PIM to cover both Azure AD roles and on-premises admin groups provides comprehensive privileged access governance.
