Answer Posted / natraj
A firewall is a set of related programs, located at a
network gateway server, that protects the resources of a
private network from users from other networks. (The term
also implies the security policy that is used with the
programs.) An enterprise with an intranet that allows its
workers access to the wider Internet installs a firewall to
prevent outsiders from accessing its own private data
resources and for controlling what outside resources its own
users have access to.
