Sorry, but that is way off base. You can filter by anything that you want and it will not affect your ability to "get" a signal. You will still be able to receive packets, crack the WEP keys, and then enumerate the network. Ever heard of MAC spoofing? Nice try, but wrong info. Wireless is inherently insecure without third party solutions in place. And even then for the most part, you can keep me out, but you can't keep the signal in. If it is sensitive data, encrypt it. The concept of MAC filtering is to keep someone from associating with the AP. Setup a stronger "Rogue AP" and then the fun really begins. Like everyone handing over their credentials. I do not know who said it, but the saying goes " Having wireless in the building is like having a network jack in the parking lot". Wireless is great. Use it, enjoy it, but know the limitations of what you have.

You can't even get a signal unless you're MAC address is allowed..

So if you can find a way to manually change your WEP key every 10 minutes then you are in good shape! :) Seriously though - Help is here - mostly in the form of WPA. You can read up on that in these two articles: http://www.nwfusion.com/research/2003/0331wpa.html http://newsforge.com/newsforge/03/06/09/1331225.shtml?tid=14 http://www.devx.com/wireless/Door/11331 Also, I just got a bunch of info from this list about tips for locking down security. I can send you a consolidation of what I learned if you'd like. -----Original Message----- From: Matt Stern [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 08, 2003 10:22 AM To: Leif Gregory Cc: [EMAIL PROTECTED] Subject: Re: Wireless Networking Hello all: I've heard that wireless (802.11b, a, and g) are inherently insecure due to the ability to sniff packets. However, what about using the 64 bit or 128 bit WEP encryption that comes with the router (such as linksys). Isn't that good enough? Where can I get more info on locking down wireless?
