Hello List,

The general rule with firewalls are everything is blocked by default.  Only
open up exactly what you need to do business and nothing more.  Which port
you open and use depends on how you are going to connect.  If possible us
SSL and put the device you connect to in a DMZ.

Good Luck,

Subject: trusted & untrusted ports




Dear List,

I would like to open ports in my firewall so that i can access some
applications out of my network. consequently, I have two questions:

1 - How I can Identify trusted ports vs. Untrusted ports ? assuming trust
is
directly concern with the security prespective (include virus, worms,
hack,
...).

2 - corret me from wrong please. "There are two types of applications: web
application (access through the http port), and client/server application
(access through a defined port should be opened on the internet gateway).

your feedback and respond are highly appreciated.

honeslty, I am getting very good information out of this email list, so
hopefully the answers will be benifitial to me and other members will to
improve their knowledge base.

regards,

Hilal
