Securing a cellular wireless network for a home business

[hlthe2b]

I am using a 3g/4g Cellular (sprint) network devise for a home business--one that will deal in some data work that requires strict protections. Some of the contracts I am going after require documentation of adequate security systems in place. I NEVER use public wireless, yet travel extensively, which is why I have gone the cellular wireless route rather than a faster, yet more expensive "wired" DSL or broadband solution.

I have done the following:
1. Set up as a WPA2
2. named the wireless network/SSID name using a combination of letters and numbers that is not linkable to me or my business. (I have to let it broadcast the SSID because I use Windows XP).
3. Established a complex password of 22 combined letters, characters and numbers
4. Have good firewall and security systems on all connected devices.

Beyond having good back up systems and ability to protect data devices against fire, water, and theft, is there anything else DUers can think of that is reasonable to protect with regard to cyber security? Thank you for your thoughts.

1. From a cursory look, it appears you have all of your bases covered

But, you could go further and completely encrypt the data on the computer itself. I use TrueCrypt ( http://www.truecrypt.org) which is pretty good (it's open source and free). That way, even if someone breached your network security they would still have to hack the encrypted files stored on your TrueCrypt partition.
