Identity and Access Management (IAM) is a security framework that defines and manages the roles and access privileges of individual network entities. It's the logical choice for enabling multi-factor authentication (MFA) via the Microsoft Authenticator app, as MFA is a core component of verifying a user's identity before granting them access. Information Rights Management (IRM) is designed to protect sensitive information from unauthorized use. Classifying documents and applying restrictions, such as preventing copying or printing, is a direct function of IRM. Finally, Compliance Manager provides a dashboard with data-protection recommendations and generates reports on an organization's compliance posture, making it the appropriate tool for both data-protection dashboards and providing reports to auditors.
