[nflug] **Security Group**

[nolf]

I was just checking the recent Perl Mongers meeting and it occured to me if
there is a Security Group too here in Buffalo.

By now am sure that many people here are interested in securing their
computers and their networks.
However, am not sure how many people believe in the open exchange on all
matters viz-a-viz **security**

Its a tricky topic to be put on here, but nevertheless a hackerish approach
to things is very important; I believe.
This might shock some of you out there but, presuming this archive is more
of a free information
exchange between creative and smart individuals, I am sure this should not
tickle many of you who seek the
pleasure of the wild.

For starters, I post here something that I was trying to figure out for
quite some time now. I have an idea
but would be more than happy to  get all of your feedbacks-

Here's a hypothetical situation...

An ISP sets up shop and offers interent connections on private IP addresses.
They follow
a static IP Addressing scheme. They further use username and password
binding to the user MAC
for obvious reasons. Now, an ingenious user takes an IP from an active user
in the same subnet
(not currently active though or could even be active.)

He changes MAC to reflect the chosen user and emulates him. In full control
of the system, he
performs active and passive reconnaissance.

Is there a definitive way of finding out the person in question??
