I hate to sound like an adobe sales person (I'm not, but I do like their acrobat line of products), but they have a product that serves as a document policy system. Check out adobe document center.

Also, I don't like using MAC's for anything including as a computer :-) or a method of what IP/vlan/access a system can have because pretty much most all NIC's allow you to change their MAC. Now the 3Com cards on the other hand use crypto keys stored right in the card. I'd like to see that spoofed.

That's hilarious. That is NOT at all anything that I had considered. I was thinking more along the lines of MAC address, networking, somehow something is being verified that the laptop is encrypted or it was not allowed on the network or something of the sort... ;p

Now encryption can be managed centrally or remotely and can ensure cryptographically based chain of custody, from the sectors on the drive, through the Network and then on to the destination system or even to the field level in databases that might live on the destination systems as well. Everything is encrypted at the object level, so you can literally have a single word document that allows for three different viewers to see different levels of redacted documents or the like (there are many other cool things that their solution does, but this is one technique...)

That is pretty nifty. That type of functionality I didn't even think was possible. I will be checking into this for sure.

I hear you there. I have found through my excessive blunders in the computing world that have turned me into the find Computer Nerd that I am today (If you could only "hear" my sarcasm... ;p) that it's best to plan on the worst. That way, if things actually go as desired and not as they "do", then you can take that extra time and run out for a beer or two.

It sounds like it will. Funny, I didn't get involved in this thread, looking for a new vendor. But I'll have to check into the TECSEC. It'll be a while, as I'm swamped right now, but I will post my results some time in the future. From the sounds of it, it sounds like we may have an alternative to our current solution.
