Cisco 1100 "Basic" Security

Just a quick question from a wireless newbie- how likely is it that someone from outside could get into a wireless network with only the following configured?

MAC address filtering with 3 specific MAC addresses of wireless devices in use.

Changed the default admin logon (of course) and the SSID. Set the AP to not broadcast the SSID.

No WEP or any other security. In this particular configuration, the potential for sniffing the Web-site traffic being broadcast isn't a big deal.

How easy is it to spoof one of the three specific MAC addresses (not knowing what they are) or to bypass MAC filtering altogether? Can the MAC be sniffed off the air?

Thank you!

Ken

MAC address can be sniffed off the air. Your best bet is to read up on wireless security from our SAFE blueprints. Go to:
