Using Cell Phone As A Mobile Access Point

Hi Everyone,

My boss uses her phone as the wireless access point for her internet connection. I'm not familiar with this route.

She has all her business data/Quickbooks on this lappy, so, I was wondering if anyone could shed some light on what I can do to keep this secure for her.

I know how to keep her secure if she was using a router, but using the phone has me scratching my head.

Any help appreciated.

Thank You,

Sphere
 
Basically all the ones ive seen make the pc directly connected to the internet. You may want to install a software firewall if possible.
 
Thanks RadiclDreamer,

Were ok with a software firewall, but my concern is also someone leeching on to her connection, is there anything I can do to prevent that?

Thanks
 
I am just a little confused about the situation.

Are you saying her phone connects via her carrier and then she connects to the phone using 802.11 a/b/g? Or does she simply tether (via USB cable) her phone to the laptop.

If not, then on the air interface (cell phone to providers network) she will be as secure as the Technology Type of her provider allows.

As far as the providers IP network, well it is still a public IP given, and there's not too much you can do about that as with any ISP.

 
Well, she would have whatever inherent protection from eavesdroppers that normally comes with her service.

For example, last I had checked, there really isn't any real-time decryption for CDMA (the technology footprint used by Verizon Wireless, Alltel, Sprint and others)

I believe it is the same for GSM and UMTS/HSPDA but I am not 100% sure.
That handles the air interface, but on the backhaul portion you are still given a public IP, but it looks like you took care of that with a software firewall.

If you wanted an even extra layer, you could use VPN.
