2. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t OIS SSO - Summer 2012 Updates - 2 Primary objective Prepare CERN Authentication for IAA Extend SSO to HEP community through Federation –Allow HEP members to access CERN resources with their local IDs. –Decrease the ‘CERN Account’ requirement Extend SSO to Public Services authentication (Google, Facebook, etc.) –Allow people to access CERN resources with their public credentials (e.g. Gmail account) –Decrease the ‘Lightweight Account’ requirement

3. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t OIS SSO - Summer 2012 Updates - 3 Technical objectives Improve service, fix issues and requests Provide Strong Authentication methods –SMS one time password, Yubikey, Smartcard Allow SSO Authentication using scripts & programs Facilitate SSO management for Application owners Address the large number of E-Groups problems –‘Header too big’ Apache issue

4. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t OIS SSO - Summer 2012 Updates - 4 SSO Management Site http://cern.ch/sso-management Application registration & lifecycle –Reassign the registration to another account. Identity Class (Basic) Authorization –Using the Identity Class, restrict access to the Application at the SSO level. –Lightweight accounts not authorized by default E-Groups Authorization –Filter E-Groups needed for Authorization –User token size decreased, containing E-Group membership only within the E-Groups filter.

5. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t OIS SSO - Summer 2012 Updates - 5 Identity Class Authorization Provide Basic Authorization using a unique value representing the level of assurance (LoA) of the user and the authentication method used. CERN Registered Represents the currently active CERN primary accounts. ​ CERN TrustedRepresents the currently active CERN secondary and service accounts. HEP Trusted ​ HEP people registered in the CERN HR database, authenticating using their HEP systems (through Federation). Named Identity ​ Ex-members of personnel, like retirees, former staff, etc. They still have an entry in the CERN HR database but no CERN account anymore. Anonymous Identity ​ Anonymous unverified people, like external/lightweight accounts, Facebook/Google accounts, Federation accounts not verified. Default basic authorization set to CERN Registered only. Configuration at SSO level through http://cern.ch/sso- managementhttp://cern.ch/sso- management Configuration at Application level through usual configuration files.

7. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t OIS SSO - Summer 2012 Updates - 7 E-Groups Authorization Current situation: –An account can be member of hundreds of E- Groups –The token size can be huge when the Application needs only some to handle Authorization. New Authorization E-Groups Filter: –Define the list of E-Groups needed for Authorizations. –The User token will contain E-Group membership only within the E-Groups filter.

8. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t OIS SSO - Summer 2012 Updates - 8 Authentication Methods Standard Authentication: –Forms: user types in his login and password. –Kerberos or Windows: reuse the current Kerberos or Windows (NTLM) credentials for authentication. –Certificates: use your CERN CA or EuGridPMA (IGTF) trusted certificate to authenticate. Two Factor Authentication: –Smartcard: use a CERN Smartcard to authenticate (pilot, see http://cern.ch/smartcards).http://cern.ch/smartcards –Yubikey: use a Yubikey hardware token to authenticate. –SMS One Time Password: validate your authentication with a PIN code sent by SMS to your CERN GSM. Federation Authentication: –USATLAS/BNL, INFN, Switch AAI, etc... : coming soon. Public Services Authentication: –Google, Facebook, Live, Yahoo, Orange.
