The Internet is a wonderful technological advance that enables
businesses and individuals to access a vast amount of information
and communicate with people all over the world. Businesses and home
users increasingly are getting their computers and networks connected
to the Internet. However, the major danger when you connect your
computers or networks to the Internet is that outsiders may be able
to access to your computers or networks through the Internet. These
hackers could steal or destroy information stored on your computers.
GallantWEB comes with a function called a firewall. The
firewall safeguards the Internet connection to defend against attack
from the outside, just like a firewall in building construction
that keeps a fire from spreading. It is a security measure to control
access to your computers and networks behind the firewall. When
you use the GallantWEB to connect your private computer or network
to the Internet, information residing in the GallantWEB and the
computers on the network are protected.

GallantWEB firewall utilizes a technology called packet-filtering.
Communication on the Internet is carried by exchanging small chunks
of data (packets) between computers. The GallantWEB firewall inspects
every packet coming from and going to the Internet. It matches the
packet against a set of rules. The rules determine whether the packet
should be admitted into the GallantWEB, forwarded to the network
behind the GallantWEB, or discarded. Using a set of carefully defined
firewall rules, the GallantWEB firewall can block intrusion, attacking
and hacking by persons external to your computer or network.
GallantWEB is shipped with a set of firewall rules carefully designed
to suit the requirements of most business and home networks. It
also provides an intuitive Web-based user interface to modify the
firewall rules. You can either use the standard GallantWEB firewall
and get immediate protection for your computer or network, or customize
the firewall to accommodate any special requirements.
