Windows 8 Firewall is a barrier between your computer and the outside world. When a remote computer attempts to access a computer that is protected by a firewall, it is not able to connect and the data that was sent is ignored and discarded and it prevents the outside world from being able to access your computer. The basic Windows 8 Firewall setting includes turning the firewall on and off and allowing a program through it.
Windows 8 allows this tool to filter both inbound and outbound traffic or set rules and exceptions, depending on the type of network to which you’re connected. Windows 8 firewall is turned on by default and much more advanced than previous Windows firewalls and it runs silently in the background as a service. Microsoft Windows Firewall really makes it a very powerful security solution that was once provided only by advanced third-party firewall software.
