If you do not have a firewall or access-filters on your router, this
would be a fairly trivial task.

>From inside the network, stealing passwords is as simple as using a
packet sniffer.  From outside the network, attacking systems or
attaching to shared resources is a not too difficult either.

Please check out http://www.axent.com/swat/swat.htm  for more details on
the possible attacks.

Hi, We've set up a lan with some Win 95 computer based systems, and we
have
also a netscape web server and no firewall system.
We have shared some resources through our internal net.
So I've set up a password for each of them.
I would like to know if it should be possible from inside this network,
to
steal a password, or to enter through a back door into a protected
resource. 
And, how it should be possible to do this (that is , which type of
operation should be performed to break into a protected resource),  and
also how to avoid it.

Thanks in advance.
                              Ing. Giuseppe Caparrotti
