class Policy:

"""
|
|
A policy defines the conditions that must be satisfied to grant access to an object.
|
|
Unlike permissions, you do not specify the object being protected but rather the conditions
|
|
that must be satisfied for access to a given object (for example, resource, scope, or both).
|
|
Policies are strongly related to the different access control mechanisms (ACMs) that you can use to
|
|
protect your resources. With policies, you can implement strategies for attribute-based access control
|
|
(ABAC), role-based access control (RBAC), context-based access control, or any combination of these.
