Firewalls, both hardware and software, prevent dangerous data from reaching the system from computer hackers and other online threats. While hardware firewalls provide protection across the network against external threats, software firewalls installed on personal computers can inspect data more closely and also prevent specific programs from sending data over the Internet. On networks with high security concerns, combining both types of firewalls provides a more complete security trap.
