What is Azure Active Directory (Azure AD) Conditional Access, and how does it enhance security by controlling access to resources based on specific conditions? Azure Active Directory (Azure AD) Conditional Access is a comprehensive security feature in Microsoft's Azure AD identity and access management service. It enhances security by allowing organizations to control and manage access to resources based on specific conditions and policies.
