Policies, Roles, and Permissions¶
A policy is a collection of permissions to the resources in EnOS (such as services, functions, and data). You can assign the access policies to a user, a user group, or a service account to manage their access to the resources in EnOS. A policy takes effect only when assigned to a user, user group, or service account. You can assign different policies to a user, user group or service account based on the granularity of authorization supported by EnOS.
EnOS services and tools: support menu-level authorization.
Assets and data: support access to all assets within an OU.
The access policies in IAM are classified into two types: built-in policies and custom policies.
Built-in Policies¶
Built-in policies, which cannot be edited or deleted, refer to a collection of the access policies that are pre-defined for typical user roles in EnOS. For example, any user that is assigned with the “Model Administrator” role owns the write and read permissions to create, delete, edit, import, export, view, and instantiate the models under the OU.
The following built-in policies are available in EnOS.

Custom Policies¶
Custom policies refer to the access polices customized as per the needs of users and service accounts for accessing EnOS services. For example, a user that only needs to query the models may be assigned with the “read-only” permission for “Model”.
EnOS now supports custom access permissions to the following services.
Asset
Asset Tree
Model
Device Management Service
Resource Management
Product
Certificate
Firmware
