  1. Vikas Jain, Director, Product Management Application Security and Identity Products Intel Corporation Twitter: @VikasJainTweet Blog: blogs.intel.com/cloud-access-security OAuth, OpenID, SAMLMaking Sense of the Alphabet Soup for Cloud Identities

  2. Topic Agenda Cloud Identities SAML OAUTH OpenID Key Takeaways Intel/McAfee Products

  3. Cloud Identity Alphabet Soup SCIM UMA OAUTH SAML OpenID JWT Portable Contacts

  4. Why were these Standards created? Drivers • Widely adopted in Enterprises, weak adoption in consumers • Started for consumer use cases (Twitter, Facebook, etc.), moving into the Enterprise • Started for consumer use cases (Google, Yahoo, etc.), moving into the Enterprise

  5. SAML - Security Assertion Markup Language Mature standard … but carries the legacy of XML

  6. SAML Assertion SAML Assertion (Portable Identity Container) Subject User Identifier Attribute Stmts XML User Attributes Authentication Stmt Info about authentication context … Describes user identity in XML format for exchange across domain boundaries

  7. SAML Assertion Example <ns2:Assertion ID=“RbefeiCOM4ztlN2RHr9unkpQ” IssueInstant="2010-10-21T13:59:07.953-04:00" Version="2.0” xmlns:ns2="urn:oasis:names:tc:SAML:2.0:assertion”> <ns2:Issuer Format=“urn:oasis:names:tc:SAML:2.0:nameid format:entity”>ServerXYZ</ns2:Issuer> <ns2:Subject> <ns2:NameID Format=”- - -”>NameIdStatic</ns2:NameID> <ns2:SubjectConfirmation OptionalInformationHere> <ns2:SubjectConfirmationData OptionalInformationHere/> </ns2:SubjectConfirmation> </ns2:Subject> <ns2:Conditions NotBefore="2010-10-21T13:58:57.953-04:00” NotOnOrAfter="2010-10-21T14:01:01.265-04:00"> <ns2:AudienceRestriction>OptionalInformationHere</ns2:AudienceRestriction> </ns2:Conditions> <ns2:AuthnStatement AuthnInstant="2010-10-21T13:59:07.953-04:00" SessionIndex="c+dWjVJ24DMVNNo1U/cr+hgfywg=PWUYaQ==" SessionNotOnOrAfter="2010-10-21T14:01:01.328-04:00"> <ns2:AuthnContext> - - - </ns2:AuthnContext> </ns2:AuthnStatement> <ns2:AttributeStatement> <ns2:Attribute Name=“Attr1” NameFormat=“urn:oasis:names:tc:SAML2.0:profiles:attributes:basic”> <ns2:AttributeValue>Attr1value</ns2:AttributeValue> </ns2:Attribute> </ns2:AttributeStatement> </ns2:Assertion>

  8. SAML Protocols, Bindings, and Profiles Use case flows (combination of assertion, protocol, binding) Maps Protocols to std messaging(combines Assertion, protocol, binding ) Get Assertions (request/response) Defines how SAML Assertions are used

  9. SAML Use Case #1: Web Federated SSO For Cloud and Partner Apps Identity Provider (IdP) Service Provider (SP) SAML Server SAML Server Browser SAML App Authenticate Verify Identity User Store User Store

  10. SAML Use Case #2: Web Service Access Control Web Service Consumer Web Service Provider SOAP Message XML Gateway XML Gateway SAML (in WS-Security header) Insert SAML Token Verify SAML Token Web Service Client App User Store User Store

  11. SAML Use Case #3: API Access Control API Consumer API Provider XML Gateway XML Gateway SAML (in HTTP header) Insert SAML Token Verify SAML Token API Client App User Store User Store

  12. OAUTH Provides API Authorization (draft 26) Before OAUTH, HTTP Basic was primarily used by API providers to authenticate clients using username/password. Scoped access wasn’t possible.

  13. OAUTH 2 Protocol Flow (Abstract version) User / Resource Owner Client 1. Authorization Request 2. Authorization Grant 3. Authorization Grant and Client Credentials Authorization Server 4. Access Token Resource Server 5. Access Token 6. Resource Access Token allows the client to access resource on behalf of the user

  14. What’s new in OAUTH 2?

  15. OAUTH 2 Flows

  16. OAUTH Consumer Use Cases

  17. OAUTH Enterprise Use Case #1:Mobile App for Enterprise Apps Mobile App accesses Enterprise App using OAUTH authenticating the user (with OAUTH AS) using Enterprise credentials • Benefits • Enable Mobile access for Employees • Authenticated by the Enterprise • Enterprise user passwords not stored in Mobile Source: Sep 29, 2011, “Enterprise Use Cases for Open Identity: OpenID and OAuth” Gartner report by Bob Blakley

  18. OAUTH Enterprise Use Case #2:Mobile App for SaaS Apps Mobile App accesses SaaS App using OAUTH authenticating the user (with OAUTH AS) using SAML assertion from the Enterprise • Benefits • Enable Employee access to SaaS app via Mobile • Authenticated by the Enterprise • Enterprise user passwords not stored in mobile or SaaS App Source: Sep 29, 2011, “Enterprise Use Cases for Open Identity: OpenID and OAuth” Gartner report by Bob Blakley

  19. OAUTH Enterprise Use Case #3:Enterprise User accesses Partner REST app Enterprise App accesses Partner REST App over OAUTH authenticating the user (with Partner OAUTH AS) using SAML assertion from the Enterprise • Benefits • Access data in partner app under user’s identity • Allows Enterprise App to make API calls on user’s behalf • Enterprise user passwords not shared with Partner Source: Sep 29, 2011, “Enterprise Use Cases for Open Identity: OpenID and OAuth” Gartner report by Bob Blakley

  20. OAUTH Enterprise Use Case #4:Partner App accesses Enterprise REST app Partner App accesses Enterprise REST App over OAUTH authenticating itself (with Partner OAUTH AS) using Application password • Benefits • Enterprise exposes REST interface to partner • Quick adoption: Partner doesn’t need to implement SAML server • Partner app authentication secrets not exposed Source: Sep 29, 2011, “Enterprise Use Cases for Open Identity: OpenID and OAuth” Gartner report by Bob Blakley

  21. OAUTH Enterprise Use Case #5:Temp Workers access Enterprise App using FB Login Contract workers/Affiliates accesses Enterprise App authenticating themselves using Facebook login (with Facebook OAUTH AS) and Enterprise OTP • Benefits • Enterprise doesn’t have to manage temp identities • OTP provides additional security • Temp workers don’t have to remember another password Application Enteprise AS & OTP Enterprise Temp Worker

  22. OpenID Provides Federated Login (draft 10) Originally developed to prevent anonymous users from posting spam to blog comment fields … User Identifierused is a URI that’s unique across all users. Based on key-value pairs. Carry some similarities with SAML.

  23. OpenID Connect Protocol Suite Combines OAUTH 2 and OpenID 2 to make OpenID API friendly

  24. OpenID Consumer Use Cases

  25. OpenID Enterprise Use Cases OpenID has the potential to accelerate the BYOI (Bring Your Own Identity) movement into the Enterprise
