Re: How to track down a wireless hacker

[Francois Larouche <francois.larouche-ml () sqlpowerinjector com>]

Don't take me wrong I do find it intellectually challenging and fun to 
try to track someone who is hacking you, whether it be possible or not 
over wireless. And also really educative and interesting to see what 
people come up for ways to track that hacker.

But if by some luck you find who that guy is or where he is, what then? 
You call the police and tell them that a guy is at that internet cafe 
and is hacking me or my company? It ought to have a special police line 
for that :) If they ever take you seriously and come the guy would be 
probably gone. Or you grab your baseball bat and go beat him up? 
Realistically, besides the fact that it might be fun to do there is not 
much to do about it.

So the bottom line is train the people in the company and secure the 
wireless network. How you do that? That is the real good question :)

My two cents

Cheers
