Identity Provider
Overview
AD/Active Directory and Entra ID (formerly Azure AD) are Microsoft/Windows based IdP (Identity Provider) Directories that provide a database of users and permissions and lives on a Windows Server, or in Azure (the Microsoft Cloud version of this that works with Microsoft 365). AD and other IdPs catalogue users, passwords, and what permissions users have once connected. This works on a "Domain" level. Your domain is the part of your email after the @. Everyone on the same domain uses a common Directory to log in. IDM (Identity Management) is the overarching term for managing these identities and satisfies the "User Management" section of they Cybersecurity Checklist.
