Modeling Authorization for an IoT Security System with Okta FGA
Please note that at this point in time, it is not considered production-ready and does not come with any SLAs; availability and uptime are not guaranteed. Limitations of Okta FGA during the Developer Community Preview can be found here.
This tutorial explains how to model permissions for an IoT system using Okta FGA.
- How to model a permission system using Okta FGA
- How to see Okta FGA Authorization in action by modeling an IoT Security Camera System
Before You Start
In order to understand this guide correctly you must be familiar with some Okta Fine Grained Authorization (FGA) concepts and know how to develop the things that we will list below.
Okta FGA Concepts
It would be helpful to have an understanding of some concepts of Okta FGA before you start.
Direct Access
You need to know how to create an authorization model and create a relationship tuple to grant a user access to an object. Learn more →
Modeling Concentric Relationships
You need to know how to update the authorization model to allow having nested relations such as all writers are readers. Learn more → Used here to indicate that both IT Admins and Security Guards can view live video.
Direct Relationships
You need to know how to disallow granting direct relation to an object and requiring the user to have a relation with another object that would imply a relation with the first one. Learn more → Used here to indicate that "Rename Device" is a permission that cannot be assigned directly, but can only be granted through the "IT Admin" role.
User Groups
You need to know how to add users to groups and create relationships between groups of users and an object. Learn more →
Used here to indicate that security guards on a certain group are security guards on a device in that group.
Concepts & Configuration Language
What You Will Be Modeling
In this tutorial, you will build an authorization model for a sample IoT Security Camera System (detailed below) using Okta Fine Grained Authorization (FGA). You will use some scenarios to validate the model.
The goal by the end of this post is to ask Okta FGA: Does person X have permission to perform action Y on device Z? In response, you want to either get a confirmation that person X can indeed do that, or a rejection that they cannot.
Requirements
These are the requirements:
- Security guards have access to view live and recorded video from Devices.
- IT Admins can view live and recorded videos, as well as rename Devices.
- To make access management easier, Devices can be grouped into Device Groups. Security guards with access to the Device Group are Security Guards with access to each Device in the group. Similarly for IT Admins.
Defined Scenarios
Use the following scenarios to be able to validate whether the model of the requirements is correct.
There will be the following users:
- Anne
- Beth
- Charles
- Dianne
These users have the following roles and permissions:
- Anne is a Security Guard with access to only Device 1
- Beth is an IT Admin with access to only Device 1
- Charles is a Security Guard with access to Device 1 and everything in Device Group 1 (which is Device 2 and Device 3)
- Dianne is an IT Admin with access to Device 1 and everything in Device Group 1
In production, it is highly recommended to use unique, immutable identifiers. Names are used in this article to make it easier to read and follow.
Modeling Device Authorization
The Okta Fine Grained Authorization (FGA) service is based on Zanzibar, a Relationship Based Access Control system. This means it relies on object and user relations to perform authorization checks.
Starting with devices, you will learn how to express the requirements in terms of relations you can feed into Okta Fine Grained Authorization (FGA).
01. Writing The Initial Model For A Device
The requirements stated:
- Security guards have access to view live and recorded video from Devices.
- IT Admins can view live and recorded videos, as well as rename Devices.
The goal is to ask Okta FGA whether person X has permission to perform action Y on device Z. To start, you will set aside the Security Guard and IT Admin designations and focus on the actions a user can take.
The actions users can take on a device are: view live videos, view recorded videos, and rename devices. Mapping them to relations, they become: live_video_viewer, recorded_video_viewer, device_renamer.
In Okta FGA, the authorization model for the device would be:
- DSL
- JSON
model
schema 1.1
type user
type device
relations
define live_video_viewer: [user]
define recorded_video_viewer: [user]
define device_renamer: [user]
{
"schema_version": "1.1",
"type_definitions": [
{
"type": "user"
},
{
"type": "device",
"relations": {
"live_video_viewer": {
"this": {}
},
"recorded_video_viewer": {
"this": {}
},
"device_renamer": {
"this": {}
}
},
"metadata": {
"relations": {
"live_video_viewer": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"recorded_video_viewer": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"device_renamer": {
"directly_related_user_types": [
{
"type": "user"
}
]
}
}
}
}
]
}
02. Inserting Some Relationship Tuples
The requirements are:
- Anne is a Security Guard with access to only Device 1
- Beth is an IT Admin with access to only Device 1
- Security Guards can view live and recorded video
- IT Admins can view live and recorded video and rename devices
Before we tackle the problem of users access to device based on their role, we will try to grant user access based on their view relationship directly.
We will first focus on Anne and Beth's relationship with Device 1.
To add Anne as live_video_viewer of device:1:
- Node.js
- Go
- .NET
- Python
- curl
- CLI

Verification
Now that you have some relationship tuples added, you can start using it to ask some questions, e.g., whether a person has access to rename a device.
First, you will find out if anne
has permission to view the live video
on device:1
, then you will see if anne
can rename
device:1
.
Anne has live_video_viewer
relationship with device:1.

Now, check the other relationships fore Anne and Beth.
User | Object | Relation | Query | Relation? |
---|---|---|---|---|
anne | device:1 | live_video_viewer | is anne related to device:1 as live_video_viewer? | Yes |
beth | device:1 | live_video_viewer | is beth related to device:1 as live_video_viewer? | Yes |
anne | device:1 | recorded_video_viewer | is anne related to device:1 as recorded_video_viewer? | Yes |
beth | device:1 | recorded_video_viewer | is beth related to device:1 as recorded_video_viewer? | Yes |
anne | device:1 | device_renamer | is anne related to device:1 as device_renamer? | No |
beth | device:1 | device_renamer | is beth related to device:1 as device_renamer? | Yes |
03. Updating Our Authorization Model To Facilitate Future Changes
Notice how you had to add the Anne and Beth as direct relations to all the actions they can take on Device 1 instead of just stating that they are related as Security Guard or IT Admin, and having the other permissions implied? In practice this might have some disadvantages: if your authorization model changes, (e.g so that Security Guards can no longer view previously recorded videos), you would need to change relationship tuples in the system instead of just changing the configuration.
We can address this by using concentric relation models. It allows you to express that sets of users who have a relation X to the object also have relation Y. For example, anyone that is related to the device as a security_guard
is also related as a live_video_viewer
and recorded_video_viewer
, and anyone who is related to the device as an it_admin
is also related as a live_video_viewer
, a recorded_video_viewer
, and a device_renamer
.
At the end you want to make sure that checking if Anne, Beth, Charles, or Dianne have permission to view the live video or rename the device, will get you the correct answers back.
The resulting authorization model is:
- DSL
- JSON
model
schema 1.1
type device
relations
define it_admin: [user]
define security_guard: [user]
define live_video_viewer: [user] or it_admin or security_guard
define recorded_video_viewer: [user] or it_admin or security_guard
define device_renamer: [user] or it_admin
{
"schema_version": "1.1",

{
"type": "device",

"relation": "security_guard"
}
}
]
}
},
"device_renamer": {
"union": {
"child": [
{
"this": {}
},
{
"computedUserset": {
"relation": "it_admin"
}
}
]
}
}
},
"metadata": {
"relations": {
"it_admin": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"security_guard": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"live_video_viewer": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"recorded_video_viewer": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"device_renamer": {
"directly_related_user_types": [
{
"type": "user"
}
]
}
}
}
}
]
}
The requirements are:
- Anne and Charles are Security Guards with access Device 1
- Beth and Dianne are IT Admins with access Device 1
- Security Guards can view live and recorded video
- IT Admins can view live and recorded video and rename devices
Instead of adding different relationship tuples with direct relations to the actions they can take, as you did in the previous section, you will only add the relation to their role: it_admin
or security_guard

04. Modeling Device Groups
Now that you are done with devices. Let us tackle device groups.
The requirements regarding device groups were:
- Devices can be grouped into Device Groups
- Security guards with access to the Device Group are Security Guards with access to the Devices within the Device Group. Similarly for IT Admins
The type definition for the device group:
- DSL
- JSON
type device_group
relations
define it_admin: [user]
define security_guard: [user]
{
"type": "device_group",
"relations": {
"it_admin": {
"this": {}
},
"security_guard": {
"this": {}
}
},
"metadata": {
"relations": {
"it_admin": {
"directly_related_user_types": [
{
"type": "user"
}
]
},
"security_guard": {
"directly_related_user_types": [
{
"type": "user"
}
]
}
}
}
}
With this change, the full authorization model becomes:
- DSL
- JSON
model
schema 1.1
type user
type device
relations
define it_admin: [user, device_group#it_admin]
define security_guard: [user, device_group#security_guard]
define live_video_viewer: [user] or it_admin or security_guard
define recorded_video_viewer: [user] or it_admin or security_guard
define device_renamer: [user] or it_admin
type device_group
relations

define security_guard: [user]
