Firewall components ?

The major components that require licensing are listed below:

1. Firewall module
2. Management console
3. Management GUI applications, that is, SMART Clients

                        A firewall module enforces your security policy and sends log information to a management console. This is typically referred to as the firewall. The management console is responsible for storing, compiling, and pushing the security policies out to the firewall modules. It also receives logging information from the firewall modules and processes alerts. The Management GUI applications allow you to view, edit, and install security policies; view logs; and see the status of all installed firewall modules. The Management GUIs communicate with the management console, which does all of the actual work.

With some exceptions, which I will note in the following sections, each of these components may exist on separate systems. You can even mix and match the platforms on which each of these components exist.[1] For example, you can have the firewall on a Nokia platform, the management console on Solaris, and the Management GUIs on Windows.
