Which of the following is correct regarding the Cognos 8 securityenvironment?
-
Cognos 8 must be configured to use only one authentication provider at a time
-
Toperform authentication of users, a connection to the Cognos namespace must be defined
-
In Framework Manager, object security is implemented by defining access toobjects for users, groups and roles defined in theauthentication providers
-
In Framework Manager, object security is implemented by defining access toobjects for groups and roles (of which users are members), not individual users
Cognos 8 supports multiple authentication providers simultaneously, not just one. Authentication requires connection to authentication providers, not specifically the Cognos namespace (which is for internal users/groups). Object security in Framework Manager is implemented by defining access for users, groups, and roles from authentication providers. The statement about groups and roles (not individual users) is incorrect because Framework Manager does support security at the individual user level.
In Cognos 8 Framework Manager, object-level security is implemented by granting or denying access to model objects (query subjects, packages, etc.) for principals — users, groups, and roles — that are defined in the configured authentication provider(s)/namespace. This lets an administrator secure objects flexibly at the individual, group, or role level. The other options are wrong because Cognos supports multiple simultaneous authentication providers and does not restrict security to groups/roles only.
