Open wifi network security risks?
« on: September 27, 2007, 11:53:57 am »

I wanted to throw this query up in the air so we linux users can get a better understanding of (acceptable) risks associated with using an open Wifi network.

I am driven to do this as WEP/WPA is proving quite a nightmare with RT61 chipset. 

1> I am considering configuring my router to only allow my MAC addresses for my network interface devices to be allowed a connection to my wifi network.

2> Making sure my SSID is NOT broadcasted.

3> Limiting the range of allocated IP addresses my router will allow for,  lets say one device i.e. just my laptop.

4> Also making sure the router username/password are changed from factory default.

What dangers I am leaving myself open to by operating a wireless network like this?

With the MAC filtering, the password changing, and everything else, you're not too open to wardriving in my experience.  However, without encryption, that's not to say that someone won't capture the packets you send, and be able to read them because they're in plain text.  Now, if you're not dealing with any sensitive information, it shouldn't be an issue.

also in your router turn off the capability top receive "pings". Pings are often used by war-drivers, especially to crack WEP.

The risk is access to the network.

Every network has risk no matter wireless or wired.  If there are
packets flowing it can be seen.

The more trouble you make accessing your network, the less time
most (some really like the challenge) will leave your setup alone.

The next risk of course the area in which you live. If it is a populated
area risk increases. My area for example has very few houses, and
almost no traffic.
