trusted & untrusted ports

["Hilal Hussein" <hilalma () hotmail com>]

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
