Explain how to implement zero-trust security model in Azure environment.

Zero-trust security implementation in Azure:\n\n• Azure AD Conditional Access for identity-based access control\n• Azure AD Privileged Identity Management for just-in-time access\n• Azure Security Center for security posture management\n• Azure Sentinel for security information and event management\n• Network segmentation with micro-segmentation strategies\n• Continuous monitoring and threat detection\n\nImplement device compliance policies, use Azure AD Identity Protection for risk-based authentication, enable just-in-time VM access, and implement application-level security with Azure AD Application Proxy. Regularly audit and review access permissions.
