Security

Diffusion™ Cloud secures your data by requiring client sessions to authenticate and using role-based authorization to define the actions that a client can perform.

Concepts

Session
A session is an ongoing dialog between a client and Diffusion Cloud.
Principal
The principal is a user or system user that has an identity that can be authenticated.

A client can start a session providing a principal together with credentials that are used to authenticate the principal. The principal is then associated with the session. If the client does not provide a principal, and Diffusion Cloud is configured to allow it, the session is associated with the ANONYMOUS principal.

Permission
A permission represents the right to perform an action on Diffusion Cloud or on data hosted by Diffusion Cloud.
Role
A role is a named set of permissions and other roles. Principals and sessions can both be assigned roles.
Role hierarchy
Roles are hierarchical. A role can include other roles and, by doing so, have the permissions assigned to the included roles. A role cannot include itself, either directly or indirectly – through a number of included roles.
