Oracle Cloud Infrastructure Identity Domains


Oracle Cloud Infrastructure Identity Domains

Oracle Cloud Infrastructure (OCI) Identity Domains are a fundamental part of the OCI identity and access management (IAM) system. Identity Domains provide a way to organize and manage users, groups, compartments, and policies within an OCI tenancy. Here’s what you need to know about Identity Domains in OCI:

  1. Tenancy: In OCI, a tenancy is the highest-level entity and represents an isolated, secure, and self-contained environment for a customer’s resources and services. Each OCI tenancy is associated with one or more Identity Domains.
  2. Identity Domain: An Identity Domain is a logical container within an OCI tenancy that helps organize and isolate identity and access management resources. It acts as a security boundary and allows you to manage users, groups, compartments, and policies within its scope.
  3. User and Group Management: Identity Domains allow you to create and manage users and groups. Users can be assigned to groups, and groups can be granted permissions to access OCI resources through IAM policies.
  4. Compartments: Compartments are logical subdivisions within an Identity Domain that enable you to organize and control access to resources. You can create compartments to group related resources and apply policies to control access at the compartment level.
  5. IAM Policies: Identity Domains use IAM policies to define permissions and access control for users and groups within the domain. Policies are attached at the compartment level and define what actions are allowed or denied on specific resources.
  6. Security and Isolation: Identity Domains provide a level of security and isolation between different divisions, teams, or projects within a single OCI tenancy. This allows for fine-grained access control and resource segmentation.
  7. Service Usage: Identity Domains are associated with the services and resources provisioned within a tenancy. Users and groups within an Identity Domain can access and manage the resources within that domain.
  8. Authentication and Federation: Identity Domains support authentication and federation mechanisms, including Oracle Identity Cloud Service (IDCS) integration, single sign-on (SSO), and multi-factor authentication (MFA) for user authentication.
  9. Multi-Tenancy Support: OCI supports the concept of multiple Identity Domains within a single tenancy, making it suitable for organizations that require isolation and segmentation of resources and identities.
  10. Cross-Domain Access: Identity Domains within the same tenancy can establish trust relationships to allow cross-domain access and resource sharing while maintaining appropriate access controls.
  11. Audit and Logging: OCI provides auditing and logging capabilities that allow you to track and monitor user activity and access changes within Identity Domains.
