Firewalls are the most important part of your
network.
The security of your network depends mostly on how
well your firewall performs.
A firewall may come in different ways such as:
| A software installed in a Router, a server,
workstation and
on a proprietary box such as Cisco Pix and other types of boxes
to protect the whole network. |
| It could also come as software installed on
laptops and desktops
to protect only
that equipment. |
