Re: wifi file sharing security


[some typos have been removed in this post]

Thanks a lot Leonard and Bruce. I've already got the hint that both of
you are friendly and intelligent. We can get things better if we start
collaborating.

I applied MAC filtering yesterday after Bruce told. And it took less
than a minute. I agree with Leonard that MAC spoofing is like a piece of
pancake. But then it really does not require that "effort" so I dont
care for ROI, since something is always better than nothing.

However I figured out that WPA uses strong encrypting algo
(courtesy:wiki) and has been just hacked once that too in lab (wiki
might be wrong though). So I think using a strong key secures me in the
first hand.

Turning off SSID broadcast was a pain. Just when I disabled it (in my
DLink DIR-300 router), the internet connection failed, and ofcourse I
was'nt able to detect it in the windows wifi catcher. I tried using the
previous wifi profile to connect but it didnt work. And as the internet
was disabled too, i could not use internet help either. So i had to
reset the router. Really, turning the SSID off proved less user
friendly.

I need to ask one more thing about windows file sharing security. I
have a laptop and a Desktop and i do seamless data sharing between them
through the wifi router. Now I want to add more computers to the same
router loop, but I DONT WANT REST OF THEM to be able to access my files
on my laptop or desktop. (they should be limited to access only
internet)

The person on the 3rd computer can easily figure out the ip of both of
my computer using the "ipconfig /all" and enter it to his explorer to
access my files. Even my MAC address.

I think one of the solution can be that the files (on my lap & desk)
should not be accessible unless a password authentication is done. How
to do this? Any better solution?

Please help.
