Firewall Testing About VESARiA |

2.2 Why would I want a firewall?
The Internet, like any other society, is plagued with the kind of
jerks who enjoy the electronic equivalent of writing on other people's
walls with spraypaint, tearing their mailboxes off, or just sitting in
the street blowing their car horns. Some people try to get real work
done over the Internet, and others have sensitive or proprietary data
they must protect. Usually, a firewall's purpose is to keep the jerks
out of your network while still letting you get your job done.
Many traditional-style corporations and data centers have computing
security policies and practices that must be adhered to. In a case
where a company's policies dictate how data must be protected, a
firewall is very important, since it is the embodiment of the
corporate policy. Frequently, the hardest part of hooking to the
Internet, if you're a large company, is not justifying the expense or
effort, but convincing management that it's safe to do so. A firewall
provides not only real security--it often plays an important role as
a security blanket for management.
Lastly, a firewall can act as your corporate ``ambassador'' to the
Internet. Many corporations use their firewall systems as a place to
store public information about corporate products and services, files
to download, bug-fixes, and so forth. Several of these systems have
become important parts of the Internet service structure (e.g.:
UUnet.uu.net, whitehouse.gov, gatekeeper.dec.com) and
have reflected well on their organizational sponsors.
