  3. The Digital Identity Lifecycle • A business owns critical assets Hire/Fire Scenario Access Management Joining Identities Identity Data Aggregation Identity Data Enforcement Identity Data Brokering • Roles are defined • People are hired • People change role • People are fired They leave of their own accord too! • They access critical assets Role 2 Role 3 Role 4 Role 5 Role 1

  11. Access Control Theory (1) Relying Party Identity Provider Security token Security token Access granted Access denied Subject

  12. Access Control Theory (2) Relying Party Identity Provider Security token Subject

  13. Identity and Access Management Fabric Relying Party Identity Provider Identity and Access Management Fabric Subject

  14. Identity and Access Management Fabric (Inside the Firewall)

  15. Access Management Authentication • The truth, the whole truth, and nothing but the truth Authentication Protocol User-Id Password Certificate Smart-card PIN Biometric Credential Store Intruder

  16. Access Management Authentication • Multiple truths Multiple Authentication Protocols Multiple Credential Stores

  17. Access Management Authorisation • Are you on the guest list, sir? • What about you, madam? Security Reference Monitor Security Something Else Access Control Policy Who can do what to each application resource Application Resource Access Control List Who can do what to this application resource Security Token =“Who”

  18. Access Management Authorisation (non-Windows) • Does the ‘SSE’ understand the ‘token’ • Where does the ‘who’ come from? • Trap and redirect • Kerberisation Security Something Else Trap Who Authorisation Data

  19. Access Management Authorisation (non-Windows) • Does the ‘SSE’ understand the ‘token’ • Where does the ‘who’ come from? • Trap and redirect • Kerberisation Microsoft – ADFS – in W2003 R2 3rd Party – Quest/Vintela Centrify

  20. Access Management Authorisation Manager • Calculates ‘who’ can access a resource: • Static Security Groups • Dynamic result-set from a script or program • Dynamic LDAP query • IIS URLAuthorisation AD getGroup Other Data (&(company=MyCo)(objectcategory=user)(objectclass=user)) Application Resource Authorisation Manager Script http://myserver/myapp

  21. Single Sign-On • Simple SSO • Single Authentication Authority, Single Server • Single Authentication Authority, Multiple Server • Complex SSO • Single Credential Set • Token-based SSO • PKI-based SSO • Multiple Credential Set • Credential Sync (Consistent Sign-On) • Client-side Credential Mapping • Server-side Credential Mapping

  22. Authentication Service Token Validation Trust Simple SSO AuthN Exchange Credential Store (probably LDAP directory) Replication AuthN Exchange Resource Server

  23. Simple SSO: Product Examples • MS Windows • Novell Netware • RSA ClearTrust • HP OpenView Select Access • BMC .Net Identity Manager (Partial List!)

  24. No SSO AuthN Exchange Authentication Service Credential Store (probably LDAP directory) AuthN Exchange Authentication Service Credential Store (probably LDAP directory)

  25. Complex SSO: 1 Credential, Token-based AuthN Exchange Authentication Service Credential Store (probably LDAP directory) Temp Token Temp Token Trust Authentication Service Credential Store (probably LDAP directory)

  26. Token-Based SSO Examples • Kerberos • Microsoft Windows 2000 and higher • Cybersafe Kerberos • Unix Kerberos (HP-UX, MIT, Sun SEAM) • Federation • RSA Federated Identity Manager • Microsoft ADFS (W2003 Server R2, 2005) • Web Access Control • RSA ClearTrust • BMC .Net Identity Manager • Microsoft ADFS (W2003 Server R2, 2005) (Partial List!)

  27. Consistent Sign On: Password Sync AuthN Exchange Password Crypto System PW trap plaintext pw cyphertext pw plaintext pw Authentication Service Credential Store (probably LDAP directory) AuthN Exchange Normalise identities - metadirectory Password Crypto System Password Copy Service cyphertext pw Authentication Service Credential Store (probably LDAP directory)

  28. Password Sync Solutions • Microsoft MIIS 2003 • BMC .Net Identity Manager • M-Tech Psynch (Partial List!)

  29. Complex SSO – Client Cache AuthN Exchange Authentication Service Credential Store (probably LDAP directory) Password Cache AuthN Exchange Authentication Service Credential Store (probably LDAP directory)

  30. Complex SSO – Server Cache AuthN Exchange password Authentication Service Credential Store (probably LDAP directory) Client Installed SSO Agent AuthN Exchange Authentication Service Credential Store (probably LDAP directory)

  31. Single Sign-On Complex SSO – Server Cache • Understands password change dialogs • Auto-generates new passwords • SSO Agent detects login dialog • Retrieves credentials from ID store & fills in dialog ID Store Client Login User object User-id: Client-side SSO Agent SSO Attributes: User-id: Password: FSmith Password: *****

  32. Complex SSO – Server Cache • Passlogix v-GO SSO • RSA Sign-On Manager • Protocom Secure Login

  35. Conventional Access Control ‘Submit order’ requires [Name,Password] cred • Read policy for ‘Submit Order’ Server Client 2. Call ‘Submit Order’ including [Lana, ****]

  36. Claims-Based Access ControlDelegated Authentication ‘Submit order’ requires {Role} from STS_Authentication • Read policy for ‘Submit Order’ Server • Read policy for Request Security Token • Request Security • Token passing [Lana, ****] {Role} requires [Name,Password] cred Security Token Server STS_Authentication

  37. Claims-Based Access ControlDelegated Authentication ‘Submit order’ requires {Role} from STS_Authentication • Call ‘Submit Order’ with security token Server {Role=Purchaser}signed STS_Authentication {Role=Purchaser}signed STS_Authentication 4. Request Security Token Response Security Token Server STS_Authentication Mapping: (Lana,****)  {Role = Purchaser}

  38. Claims-Based Access ControlDelegated Authentication and Authorisation • Read policy for‘Submit Order’ ‘Submit order’ requires {Submit order} from STS_Authorization Client • Read policy for Request Security Token Server • Request Security Token passing [Lana’s Kerb ticket] • Read policy for Request Security Token {Role} requires[Kerb ticket] or [Name/Pwd] cred {Submit order} requires {Role} claim from STS_Authentication Security Token Server STS_Authentication “Identity claimsprovider” Security Token Server STS_Authorisation “Authorisation claimsprovider”

  39. Claims-Based Access Control Call ‘Submit Order’ ‘Submit order’ requires {Submit order} from STS_Authorisation {Submit order = True}signed STS_Authorisation Client Server {Submit order = True}signed STS_Authorisation {Role=Purchaser}signed STS_Authentication {Submit order} requires {Role} claim from STS_Authentication {Role=Purchaser}signed STS_Authentication Security Token Server STS_Authentication Security Token Server STS_Authorisation Mapping: Lana  {Role = Purchaser} Mapping: {Role = Purchaser}  {Submit order = True}
