By spoofing I meant trying to bypass restrictions that would usually rely on evaluating the MAC address. A crypto cert embedded in the card would easilly provide absolute assurance that the system is indeed supposed to be on the network. I wasn't refering to it providing additional protection against external traffic, but that's also true that the crypto would only be in affect among themselves providing privacy for all traffic over the wire between those systems. However, 3Com also has some sort of central policy management software that, according to the literature, looks like it can do a lot in an infrastructure that uses these cards.

Check out adobe document center.
You're right, Adobe makes a great solution for digitally signing documents and for augmenting e-Discovery efforts. Once we realized a solution was needed in an effort to augment the last FDE effort, we made several attempts to get Adobe to support a Pilot, but they seemed too busy to help out. Hopefully, now that I have a bit more time we will be able to track down the right people and put the solution through an appropriate bake-off with other products, as we have done in the past with other solution sets... Presently we know that the solution is much like a hot rod, but we haven't gotten a chance to put it up on a lift and fully inspect the solution or kick the tires...
Also, I don't like using MAC's for anything including as a computer :-)
Turns out that most of the Executive level clients that I have, "do like them and do use them in support of business efforts" and that makes them more important to secure and manage than most of the other systems in the enterprise, (at least for the enterprises that I work with).
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.
Agreed, this is a huge, huge problem! End Point Awareness, eTelemetry, enterprise Data Analysis and Transactional Auditing (eDATA), IP Based Transactional Accounting and Layer-8 correlation efforts are all moving towards an appropriate solution to this problem.
One of the projects that I have undertaken is to build a company with a heart, and to start out by "Reuniting all of the lost and orphaned packets of the world with their Parents (PIDs)". To that end, we have been working on enhanced mechanisms for following packet generation from the very soul of the process and all the way through its logical course of action on the remote system or application. Packet Based Chain of Custody is the next big forefront in Internet-Networking Security at all levels around the world.
Now the 3Com cards on the other hand use crypto keys stored right in the card. I'd like to see that spoofed.
I don't want to speak out of turn, but I think that the 3com cards will prevent data and streams from being spoofed amongst themselves, but not necessarily true for the Layer two indicators when the NIC's send traffic to systems outside of the gateway, proxy, or even to other systems within the same broadcast domain (to other systems) that don't have the compatible 3Com cards.
Hope this makes sense and helps... v/r Bob +12404756858 -----Original Message----- From: "Rob Thompson" <my.security.lists () gmail com> Date: Thu, 27 Sep 2007 14:58:32 To:"Bob Beringer" <bob.beringer () usa net> Cc:"Lafosse, Ricardo" <rlafosse () sfwmd gov>,security-basics () securityfocus com, "Bob Beringer" <bob () eor us> Subject: Re: Full Disk Laptop Encryption On 9/27/07, Bob Beringer <bob.beringer () usa net> wrote:
MAC agents, I do not know what you are referring to with this.Meant to be "MAC FDE" == FDE for PowerBook, MacBook Pro's, ect...
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
Data-in-Motion - are you talking about data after it has physically left your hard drive. Ie. e-mail, thumbdrives, network traffic, etc...Exactly! 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. <snip>
More setup time and effort is a small price to pay when you have a more efficient and properly configured solution deployed. It is well worth the time, IMO.Agreed, but sometimes you want to know that the solution is going to take a bit of effort to properly plan and deploy, so that you don't assume it will be less effort and wind up over budget or red in the face due to over-committing to the folks around you. (So it was my way of putting a small disclaimer and friendly heads up, so that you know that along with more power comes more responsibility ;-))
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.
I will have to check into this TECSEC. My curiosity is piqued. Thank you for the tip.Ask to talk to Jay Wack and tell him that Bob Beringer sent you, he is a busy man but he is the right guy to talk to...I hope that this information helps :-)
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. <snip> -- Rob
