re: Sharing internet through Citrix (or better solution) in isolated network?

Hi Ali,

thanks for your replay .
Answer looks fine but I`ve few question about anonymous account :

What if a session is infected by malware ?
will it cause whole server infection ?
if for example a malware is installed in running session , will it
affect other "anonymous" users ?
Will malware/infection be cleaned up , after next login ? ( something
like a restore-point in VMware )

while keeping your advice for a short time deployment ,
I`m looking for a long-term solution , every user have his own
customized settings , like
boomarks , stored cookies ,etc... . And isolating users as much as
possible. for example
if a user mess his session with visiting a malware site , other users
stay safe .



best regards
Hamid,kashfi

The best way I have found so far:

Publish IE/Firefox on Citrix, and use "Anoymous Citrix users
accounts". Clean Anonymous user space after logoff.

This works very well, if you don't need to track your internal user's
activity on the internet i.e. you trust your internal users.

Hi list ,

I`m preparing solution for providing internet-access to internal
users . What I`m looking for is a solution that completely isolate
internet usage and internal systems.

I`m thinking about publishing internet through Citrix based solution,
and keep everything restricted on citrix server/sessions.
But I though there must be better solutions ,as using Citrix p.server
for such case have it`s own security risks , some of them hard to
skip !

The good point about terminal based solution IMO is keeping user
workstation clean and (almost) isolated, as it will act like a
sandbox
for running browser .
Any comments?

As always , open-source solutions (if any) are more welcome :)




I`l like to hear your personal experiences both as user &
administrator
of such service.


regards
H.K
