Enhance Microsoft security by ditching your hybrid setup for Entra-only join

Summary of the Article:

Microsoft is gradually phasing out Active Directory (AD) in favor of Microsoft Entra (formerly Azure AD) to enhance security, simplify infrastructure, and align with modern cloud-based practices. The shift from hybrid setups, which combine traditional AD with cloud-based services, to an Entra-only model reduces risks like lateral movement attacks and eliminates the complexity of managing both environments.

Key points include:

• Security Benefits: Entra-only setups use centralized identity management, multifactor authentication (MFA), and compliance enforcement via tools like Microsoft Intune.

• Infrastructure Simplification: Moving away from on-premises systems (e.g., domain controllers, DHCP servers) and relying on an internet connection for device enrollment via Autopilot.

• Application Compatibility: Organizations must inventory their applications and determine whether they support modern authentication methods. Legacy apps over 10 years old may necessitate hybrid setups.

• Group Policy Review: As organizations transition to Entra, group policies should be reviewed and adapted. Intune and ADMX templates can replace many traditional policies.

• Best Practices: Kerberos key rotation remains essential in Entra environments, ensuring secure authentication.

• Future Features: Entra-only devices benefit from updates like Windows 11 web sign-in support and new Autopilot enhancements.

Organizations should begin planning their transition by assessing application compatibility, revising group policies, and working with vendors to modernize outdated systems. Early adoption ensures readiness for Microsoft's eventual phasing out of Active Directory.
