GIAC GSSP-NET-CSHARP Question Answer

Dilton works as a Software Developer for GREC Research Center (Central). This research center has its subsidiaries in several different cities. Dilton wants to retrieve a Soil Test Report for the Geological Survey Department. He wants the test report to be available to all the members of the department over the Internet. He creates an XML Web service named SampleReport. SampleReport contains a Web method named SoilTestDetails that requires additional security.

Dilton decides to use generic role-based security to secure the SoilTestDetails method from unauthorized users. Dilton writes code to ensure that once a user is authenticated, a user identity named Generic is created. The Generic user identity has a group membership named GeoSurvey to allow the authenticated users access to the SoilTestDetails Web method. Which of the following code segments should Dilton use to accomplish the task?

GenericIdentity GenIdentity = new GenericIdentity("Generic", "Custom");

string[] GeoRoles = {"GeoSurvey"};

GenericPrincipal GeoPrincipal = new GenericPrincipal(GenIdentity, GeoRoles);

Thread.CurrentPrincipal = GeoPrincipal;

IIdentity GeoIdentity = new GenericIdentity("Generic", "Custom");

WindowsIdentity WinGeoIdentity = (WindowsIdentity) GeoIdentity;

string[] GeoRoles = {"GeoSurvey"};

GenericPrincipal GenGeoPrincipal = new GenericPrincipal(WinGeoIdentity, GeoRoles );

WindowsIdentity.Impersonate(WinGeoIdentity.Token);

IIdentity GeoIdentity = new GenericIdentity("Generic", "GeoSurvey");

IPrincipal GeoPrincipal = new WindowsPrincipal((WindowsIdentity) GeoIdentity);

Thread.CurrentPrincipal = GeoPrincipal;
