By default, IBM Cognos 8 components do not require user authentication. Users can log on anonymously.
If you want to use authenticated logon only, you can use IBM Cognos Configuration to disable anonymous access.
In each location where Content Manager is installed, start Cognos Configuration.
In the Explorer window, under Security, Authentication, click Cognos.
The IBM Cognos resource represents the Cognos namespace. The Cognos namespace stores information about IBM Cognos groups, such as the Anonymous User, contacts, and distribution lists, and refers to objects in other security namespaces. For more information, see the Administration and Security Guide.
In the Properties window, click the box next to the Allow anonymous access property and then click False.
From the File menu, click Save.
Now, users are required to provide logon credentials when they access IBM Cognos resources.
