A firewall is a protective system between a computer network and the Internet which scrutinizes every data that enters and exits the network. It is chiefly designed to permit or deny network transmissions based on the configuration. Firewall protects the resources of a private network from users of other networks as well as controls what outside resources its own users have access to. The firewall system analyses whether a network communication is legitimate or not based on a set of rules. This barrier prevents unauthorized access to your network from external sources and ignores information transmitted from unsecure and potentially unsafe locations. It serves as a barricade against most forms of attacks and threats in the online world.   Whether a massive corporate network or a small scale home network, the security issues that both face may mostly be the similar. If your network has firewall protection, you can access without worry of offensive websites and potential hackers. Along with limiting access to your computer and network, the firewall allows remote access to a private network through secure login procedures and authentication certificates. Firewalls are of two types: hardware firewall and software firewall. Hardware firewalls are stand alone devices which are plugged in between the modem and one or more computers. Hardware firewalls provide a strong degree of protection and can be implemented without difficulty in configuration. Software firewalls are a set of related programs that should be installed in individual computers. The user can customize the program as well as possess certain control over its function and protection features. Software firewall protection does not secure a whole network but only the computer in which it is installed.
