What is the software system that stores, organizes and provides access to information in a directory for entities such as people, groups, devices, resources?

• A. Identity Store
• B. Directory Service
• C. Identity Provider (IdP)
• D. Access Management

Answer: (B)

A directory service is the software system that stores, organizes, and provides access to information in a directory for entities such as people, groups, devices, and resources. It acts as the central repository of identity data and enables structured lookup and retrieval of attributes (like user IDs, group memberships, device identifiers, and resource permissions). This makes it possible for applications and services to authenticate, authorize, and enforce policies using consistent identity information. Directory services typically support established protocols such as LDAP and Kerberos, and they serve as the trusted source of truth that identity providers and access-management components rely on. While an identity store is related, and an IdP focuses on authentication and federation, or access management on policy enforcement, the directory service is the core system that stores, organizes, and provides access to the directory information itself.
