Problem
Security is internal (we trust our DC,LDAP)
Organizations start consuming 3rd party services
How do we manage our Customer / Client DB
What if I don’t know his ID ? Origin ?

OAUTH
Misconception #1: OAUTH != Auth0
Misconception #2: It is used to AUTHORIZE not Identify
Purpose: Provide temporary access to your information
Method: JWT - Json Web Token

OAuth2.0 Usage
Resource Owner (You!)
Standard web login (username / password)
Client / Application
Authorization Server

Client / Application ID
A way for the identity provider to Identify the
Client / Application
Client Secret
A unique identi
fi
er of that application ID
OAuth2.0 - Behind the scenes
zero trust policy

Client / Application ID
A way for the identity provider to Identify the
Client / Application
Client Secret
A unique identi
fi
er of that application ID
OAuth2.0 - Behind the scenes

A token proving the ID is valid

CONCENT
A token proving the ID is valid
GRANT
Based on the Scope the App/Client ID
has permissions to access

19.
OAuth = Authorization (a.k.a access)
grants access to a resource !
Identifying the user is the application / client’s job !
grants are provided via token
tokens expire !
We want to limit the duration / validity of the grant token

20.
The Client Application has no record of the user
How he logged in
When he logged-in or logged-out
Only the authorization server u with the resource owner !
OAuth = Authorization (a.k.a access)

Purpose: Identity & Authentication layer for OAuth
Method:
1. Dedicated Service Endpoints
