## About Network Configuration Options

The following table describes the choices to consider when deciding the level of security for the system.

Network Configuration | Description
--- | ---
Site LAN connected to a system's firewall | Because the system is integrated into your network, you can log in to any host on the network and get access to the system to manage it. The system is visible to and can be discovered by third-party software. See Managing From the Site LAN for definitions of the protocols and management options.
Site LAN with restricted services | Although the system is still visible on the network, access to it is restricted by the selective disabling of services through the system's firewall. For example, you can enable the management and diagnostic software but disable the ability of third-party software to discover the system. See About Restricting Services for more information.
No site LAN; isolated system | To get access to the system, you must connect a computer to it. See Administering a System Isolated From the LAN for more information.
