In using network software, the size and scope of a network plays a key role in decision making. Companies or other parties can choose specific network software tools for setup and installation. Other network software resources help administrators and security personnel to monitor a network to protect it against a range of attacks, to prevent data breaches, or to limit unauthorized access. Other tools help to make network operations work better.

Another category of network software is related to network virtualization. With new virtual networks, various tools take the place of old legacy systems built on physical hardware setups.

In general, network software must be applied according to security needs. This can include factors such as whether a network is attached to the global Internet as well as specific goals and objectives for use.
