OpenID - How does it work? User Hans Muster (Domain: www.iid.ch) AUTHENTICATION Identity Provider e.g. clavid.ch hans.muster.iid.ch Identity URL OpenID=hans.muster.iid.ch e.g. hans.muster.iid.ch Enabled Service Geneva Application Security Forum 2010, March 4th 2010 Page 5

OpenID - How does it work? Step 1: A user decides to use a personalized Internet Service supporting OpenID (e.g. local.ch). The user clicks on „Login using OpenID“ and enters its OpenID (e.g. hans.muster.iid.ch). Step 2: The requested Internet Service converts the OpenID into an URL (http://hans.muster.iid.ch) and requests this URL in order to receive the Identity Provider of the user. Step 2a: In this example, the user has delegated its OpenID to the Identity Provider clavid.ch. Step 3: The Identity Provider provides possible authentication methods for that specific user (in this case “Password”). Having successfully authenticated, the next step (approval) is initiated. Step 4: The user decides on the values of the requested attributes to be provided to the Internet Service. The Identity Provider usually provides user specific Personas (attribute templates) to assist the user in this approval process. Step 4a: At this point, the user may decide to change attribute values and store them on the Identity Provider for future approvals for that specific service. Thus, a user can automate future approvals for specific Internet Services. Step 5, 6: The attribute values are then signed and communicated from the Identity Provider to the Internet Service. The Internet Service validates the signature of the provided attributes and finally accepts the user to be authenticated. Geneva Application Security Forum 2010, March 4th 2010 Page 7

OpenID - User Centric Identity Management TOMORROW ? FUTURE ? TODAY OpenID Provider Username Username Password Password Username Username Password Password Geneva Application Security Forum 2010, March 4th 2010 Page 10

OpenID - How to Integrate? Assumptions concerning your current Site • Users sign in with their username and password • There is a form, where new users have to register • Each user is identified by a unique ID in your database • A settings page let users manage their account info Recipe • Extend the database to map the OpenIDs to the user IDs • Extend the registration page with an OpenID input field • Extend the sign in page with an OpenID input field • Extend the settings page to attach and detach openIDs Geneva Application Security Forum 2010, March 4th 2010 Page 11

OpenID - How to Integrate? Ingredients • A OpenID Consumer Library • The Standard OpenID Logos • An OpenID Provider to test your site with Geneva Application Security Forum 2010, March 4th 2010 Page 12

SECTION 2 SECTION 2 SAML >What is it? >How does it work? Geneva Application Security Forum 2010, March 4th 2010 Page 14

SAML – What is it? SAML (Security Assertion Markup Language): > Defined by the Oasis Group > Well and Academically Designed Specification > Uses XML Syntax > Used for Authentication & Authorization > SAML Assertions > Statements: Authentication, Attribute, Authorization > SAML Protocols > Queries: Authentication, Artifact, Name Identifier Mapping, etc. > SAML Bindings > SOAP, Reverse-SOAP, HTTP-Get, HTTP-Post, HTTP-Artifact > SAML Profiles > Web Browser SingleSignOn Profile, Identity Provider Discovery Profile, Assertion Query / Request Profile, Attribute Profile Geneva Application Security Forum 2010, March 4th 2010 Page 15

SAML – How does it work? User Hans Muster AUTHENTICATION Redirect with Identity Provider <Response> Redirect with e.g. clavid.ch (signed Assertion) <AuthnRequest> Access Resource Enabled Service e.g. Google Apps for Business Geneva Application Security Forum 2010, March 4th 2010 Page 16

SAML – How does it work? User Hans Muster 3 2 4 Identity Provider e.g. clavid.ch 4 2 1 6 Enabled Service e.g. Google Apps for Business Geneva Application Security Forum 2010, March 4th 2010 Page 17

SAML – How does it work? Step 1: A user decides to use a personalized Internet Service connected to a SAML based Identity provider (e.g. Google Business Application Calendar). Step 2: The Internet Service recognizes that the user is not logged in yet. A SAML <AuthnRequest> is created and sent via redirect to the Identity Provider. Step 3: The Identity Provider provides possible authentication methods for that specific user (in this case “YubiKey” OTP). Having successfully authenticated, the next step is initiated. Step 4: The Identity Provider creates a SAML <Response> containing the user’s identifier for the specific target application. Then it signs the SAML <Response> and sends it via a Post- Redirect to the Internet Services (e.g. Google Calendar) Step 5: The Internet Service (e.g. Google Apps) verifies the signature of the SAML <Response> and now knows the user’s identifier provided by the Identity Provider. Step 6: The Internet Service can now be used by the user. Geneva Application Security Forum 2010, March 4th 2010 Page 18
