CLOUD IDENTITY


On-Premises, Hybrid, Cloud

Cloud Identity

• Identity Management as a Service (IDaaS)

– Externally hosted, turnkey SaaS applications that perform identity management

• Users and applications may be on-premises or hosted

– OPEX, flexible with changes in economies of scale

• Identity bridge

– On-premises component to connect on-premises and externally hosted environments

– Supports multiple identity services

MODERN BUILDING BLOCKS


Modern Building Blocks

• REST (Representational State Transfer)

– Adopted in response to the complexity of SOAP

– Uses HTTP for its request/response

– Objects are represented as URLs

– Example HTTP verbs

• GET: retrieve object attributes

• POST: create object with new attributes

• DELETE: delete object


• JSON (JavaScript Object Notation)

– Adopted in response to the complexity of XML

– Data format representing name value pairs


• Most modern identity standards leverage JSON over REST

– Peanut butter and jelly

– OAuth (authorization), SCIM (provisioning), FIDO (authentication), OpenID Connect (multi-protocol)

• Some notable exceptions are SAML and XACML


POST https://pingidentity.com:8443/Users

Authorization: Basic Y249RGlyZWN0b3J5IE1...

Content-Type: application/json

{

"userType":"spy",

"externalId":“tstark86753",

"pacsSerial":"87654321",

"active":true,

"otpSerial":"12345678",

"email":“[email protected]",

"userName":"lcarroll",

"givenName":“Tony",

"familyName":“Stark“

}

REST HTTP verb (add user in SCIM)





{

"userType":"spy",

"externalId":“tstark86753",


"active":true,

"otpSerial":"12345678",

"email":“[email protected]",

"userName":"lcarroll",

"givenName":“Tony",

"familyName":“Stark“

}

In REST, objects and endpoints have

unique URLs





{

"userType":“superhero",

"externalId":"tstark86753",


"active":true,

"otpSerial":"12345678",

"email":"[email protected]",

"userName":"tstark",

"givenName":"Tony",

"familyName":"Stark"

}

JSON data representation





{

"userType":"spy",

"externalId":"tstark86753",


"active":true,

"otpSerial":"12345678",

"email":"[email protected]",

"userName":"tstark",

"givenName":"Tony",

"familyName":"Stark"

}

OPENID CONNECT


OAuth

• Increasingly popular protocol for session management in rich mobile applications

• Mobile web applications function well with traditional enterprise authentication

• Rich mobile applications may break existing infrastructure like authentication and Web access management

Why Not Just Use OAuth?

• OAuth is:

– Valuable as an access delegation protocol

– A good fit for native mobile applications

– Friendly for developers

• OAuth is not:

– A user identity protocol

– An “identity at scale” protocol

OpenID Connect Protocols

Protocol for clients that support additional security


Protocol for simpler clients


Optional discovery of OpenID providers


Optional automated registration of clients (e.g., server applications, mobile devices)

OpenID Connect Under The Covers

• OAuth 2.0 specifications

• JSON Web Token (JWT)

• JOSE

– JSON Web Signature (JWS)

– JSON Web Encryption (JWE)

– JSON Web Algorithms (JWA)

– JSON Web Key (JWK)

FIDO


FIDO—A Tale of Two Protocols

• FIDO Unified Authentication Framework (UAF)

– Local mobile biometrics

– Initially proposed by Lenovo, Nok Nok, PayPal, others

– Also supports non-biometric authentication

• Universal Second Factor (U2F)

– “Smart” smart card

• Initially proposed by Google and Yubikey (first to partner)
