다음 중 클라우드 서비스 또는 온프레미스를 통해 배포하여 사용자 ID의 신뢰할 수 있는 소스인 IDaaS(Identity as a Service)와 통합할 수 있는 서비스는 무엇입니까?
정답: A
A directory service can be deployed via a cloud service or on-premises to integrate with Identity as a Service (IDaaS) as the authoritative source of user identities. A directory service is a software application that stores and organizes information about the users, devices, and resources in a network. A directory service provides a centralized and standardized way to manage and access the information, and to perform identity and access management functions, such as authentication, authorization, and auditing. A directory service uses a hierarchical or tree- like structure to organize the information into logical units, such as domains, organizational units, or groups. A directory service also uses a schema to define the attributes and rules for the information, such as the name, password, or role of a user. A directory service can be deployed via a cloud service or on-premises, depending on the needs and preferences of the organization.
A cloud-based directory service is a directory service that is hosted and managed by a cloud service provider, such as Azure Active Directory or Google Cloud Directory. A cloud-based directory service can offer the advantages of scalability, availability, and cost-effectiveness, but may also pose the challenges of security, privacy, and compliance. An on-premises directory service is a directory service that is installed and managed by the organization itself, such as Microsoft Active Directory or OpenLDAP. An on-premises directory service can offer the advantages of control, customization, and integration, but may also pose the challenges of maintenance, performance, and reliability. A directory service can be integrated with IDaaS as the authoritative source of user identities. IDaaS is a cloud-based service that provides identity and access management capabilities, such as single sign-on, multi-factor authentication, or identity federation, to the users and applications of an organization. IDaaS can leverage the existing user information and credentials from the directory service, and synchronize and authenticate them across different systems and platforms. IDaaS can also provide additional features and functions that the directory service may not support, such as self-service, password management, or identity governance.
