Firewall is a
powerful security system that protects your computer from various threats such as hacks, viruses, spams, spywares, and any other destructive data that attempts to penetrate your network.

All you need to do is to enable the security system. However, you can also choose to download free firewalls online or buy a product.
Basically, a firewall serves as a system blocking away all sorts of bad data. However, the function of this
security software is much more complex than what you think. For, a firewall system uses several techniques in order to fully secure your PC.
First, through the application gateway, it uses protection mechanisms to certain applications. Second, through the
packet filters, it checks all the packets and then allows or blocks them depending on their adherence to the packet rules. Third, through the circuit-level-gateway, it secures connections like Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Fourth, through the proxy server, it screens all the information that enters or leaves your computer or network. Fifth, encryption is also used to provide tighter security in various networks.
