Re: Wireless security question

As I see it you have a problem when the person communicates over the wireless sending any internal/sensitive data. For such transmission is not encrypted and goes over non-trusted network.

1. Implement port-safe or other measures that will keep track MACs on ports; or disable (if possible) unused ports (that way only approved users can tap into the wired network).

2. Produce policy that will address wireless issues; !!! Educate users !!! about threat that it might be for the company.

3. Might wan to think about buying some cheap AP, turn it on inside the office without plugging it into anything... That will take care of those close-by users who have "associate with anything" settings.

4. Enforce Policy...

5. Buy a lot of microwave ovens and run them all the time... :)

 I hope that helps.

could see external wireless networks (from other
companies around our building) and access
Internet through there. Yeah I know they're
stupid, but it's the real world!

This seems like a potential threat for taking our
data out the back door. Copy files accessed through our network to
another network and voilà! No trace at all of the

We monitor internet access and block non-company
Email (Yahoo, Hotmail etc.).


Thanks and Happy Holidays!
