These tiers are web server, applications and data and are based on business function, and are normally separated by network firewalls. As shown in the diagram below Cognos 8 BI user interface sits above the 3 tiers.Depending on what the users requirements are, you can choose different configurations but the one shown below illustrates a single server Cognos 8 BI configuration. {draw:frame} http://www.

0. doc/images/cntrl_install_order_servers. jpg Security and Distribution Looking at the Cognos 8 BI tool it seems that secutiry implementation is either not enough or too much.Not enough security can mean “when the Cognos 8 default settings are left in place and security is relegated to the user logon or no security at all” ( Volitich, Dan.

IBM Cognos 8 Business Intelligence : The Official Guide, 2008). The threat here is, anyone that would have a Cognos Connection can view or print any data that has been published by the company, delete any items they find, for example, packages, folders and reports . Too much security can occur “when the system administrator either does not understand the flexibility of Cognos 8 security, or, to be frank, the system administrator is paranoid. In this ase, legitimate business users cannot access the information they need to make sound business decisions. The business users quickly become frustrated and the Cognos 8 installation is considered a failure by the people it is meant to help the most. Every organization should be concerned both with information security (not allowing unauthorized user to access information) and content integrity (not allowing someone to remove or change content). Cognos 8 lets you apply a fine level of control over all of the features and content found in the Cognos 8 environment, ensuring that you can meet both of these objectives” ( Volitich, Dan.IBM Cognos 8 Business Intelligence : The Official Guide, 2008).

It is important for any company using Cognos 8 that they must enable and configure security before they use it. If this is not enabled then anyone that has a Cognos connection will be able to access all information and data in the program. Volitich, Dan. IBM Cognos 8 Business Intelligence : The Official Guide. New York, NY, USA: McGraw-Hill, 2008. p 592. http://site.
