When the initial security entries are created during the content store initialization, the group Everyone is a member of the System Administrators role. This means that all users have full access to the content store. To limit that access, you must add trusted users as members of this role, and then remove the group Everyone from its membership.
You must also modify the initial security settings for the predefined roles that include the group Everyone in their initial membership, such as Consumers, Query Users, and Authors. Make similar modifications for them as you do for the System Administrators role.
If you do not want to use the predefined roles, you can delete them.
To secure the Cognos namespace, modify its initial access permissions by granting access for the users you want.
When you set access permissions, you should not explicitly deny access to entries for the group Everyone. Denying access overrides any other security policies for the entry. If you denied access to the entry for Everyone, the entry would become unusable.
Your Cognos 8 installation must already be configured to use an authentication provider, which is documented in the Installation and Configuration Guide.
In Cognos Connection, in the upper-right corner, click Launch, Cognos Administration.
On the Security tab, click Users, Groups, and Roles.
Click the Cognos namespace.
For the role you want, in the Actions column, click the set properties button.
On the Members tab, modify the membership list:
Ensure that one or more users defined in the third-party authentication provider are members.
Remove the group Everyone.
Click OK.
On the Permissions tab, set access permissions for this role to prevent unauthorized users from creating, updating, or deleting the content, and then click OK.
For each role, repeat steps 3 to 6.
In Cognos Connection, in the upper-right corner, click Launch, Cognos Administration.
On the Security tab, click Users, Groups, and Roles.
In the Actions column next to the Cognos namespace, click the set properties button.
On the Permissions tab, set access permissions for the Cognos namespace to prevent unauthorized users from creating, updating, or deleting the content.
We recommend that you remove the group Everyone. However, you may leave it, depending on your requirements.
If you want, select the Delete the access permissions of all child entries check box.
Click OK.
