Building Secure Computers?
maotx asks: "Growing into the job of a system administrator, I've been tasked with something I'm not quite prepared for: purchase or build a computer that meets DoD compliance for classified 'Secret' information. Several vendors, including Dell our primary supplier, offers computers that will work, but being new to the criteria I want to make sure the right computer is purchased. The computer will be used to create secure CAD drawings (Solidworks, OrCAD, etc) and must have, from what I can tell, a removable hard drive and security stickers to prevent tampering. What is you're experience in setting up a secure computer and is it better to have a vendor do it, or yourself?"
So sayeth the editors of Slashdot.
Ask the Dept of Defense. Asking Slashdot about DoD guidelines is like asking an elementary school for details about the space shuttle. No offense to /. community.
Buildings secure computers? Computers secure building? What?
Oh, you meant "building secure computers".
My other car is first.
I heard that the first step towards building secures computers is to be attentive to small details such as spelling and grammar.

"Asking Slashdot about DoD guidelines is like asking an elementary school for details about the space shuttle."
True. But we ARE good with law, business, and economics.
Most of what you need to know is contained on the Defense Security Services (DSS) Information Assurance website: http://www.dss.mil/infoas/ The guiding document for DoD contractors is the National Industrial Security Program Operating Manual (NISPOM). Classified systems have to go through a formal certification and accreditation process before they will be approved for classified processing. Since your ultimate goal is to satisfy the accreditor, you should contact him/her as soon as possible to have them explain what will be required and to hear their particular areas of concern so that you can address them early in your design. Security paperwork requires considerable time to fill out, and mistake can result in long delays in accreditation, or even the rejection of your system.
However, it isn't enough to just build a system with the proper hardware and software configuration -- you also have to make sure that the physical environment and users will meet the requirements of the NISPOM. If you don't already have a facility clearance, then you have a significant issue to tackle before you can even build your system. I'm hoping that you are simply building a new computer to add to an existing classified network or house in an existing DoD closed area -- if not, you may find this to be a very daunting task.
"she says i'm lousy conversation. as if that's supposed to help."
First of all you'll need a server equipped with tiny C4 charges embedded in each of the hard drives. This is a handy way of deleting data on your hard drives very quickly. I hear HP can furnish these.
Second, you will need to hire a troupe of security guards to watch over the computer. Equip them with an M16's, and have them work in shifts, escorting users to and from the computers. If you can't afford a humans, several dozen trained monkeys will do the job. Just make sure and keep at least three extra monkeys on hand so you can replace the dead ones. You'll need at least two monkey handlers if you go the monkey route - one to watch over the monkeys and one to fill in when the first one gets shot.
For a bit of extra security, you can purchase an used electric chair from one of the states that have switched to lethal injection and use it as the chair for the workstation. One armed guard can stand holding the red button, ready to fry to operator in case (s)he mishandles any data, or looks at the guards funny, while another guard stands ready to kill the other in case they refuse to press the red button.
If you can't afford or find an electric chair on the retail market, submit an "ask slashdot" article and I'm sure you'll get plenty of tips on how to build one yourself.
Or if you want to save money you could just install the super secure Gentoo Linux operating system and set it to update itself via emerge automatically every hour.
It's your choice.
I don't always use unix-like operating systems; but when I do, I prefer FreeBSD.
As a US Air Force member who handles information and uses computers classified as Secret, I can tell you that there's no physical difference between a Secret machine and an ordinary one. If vendors are telling you that they can build a DoD Secret classified computer, then they are simply blowing smoke up your ass.
DoD classifications are all about policy, paperwork, and regulations. Not fancy computers. Most people, when they hear of DoD classifications and security clearances, are quick to imagine black vans, polygraph tests, and high-tech datacenters protected better than Fort Knox. Honestly, that's all a bunch of nonsense. All of the classified systems that I've used were just ordinary computers from ordinary manufacturers.
In my current workplace, we have a standard Gateway PC with a removable hard disk and a few Panasonic Toughbooks. Nothing special at all. The only visible difference between these and the regular office PCs is that they have red stickers all over them that say "Secret" and the fact that we are not to process Secret data on the unclassified PCs and vice versa. The Gateway machine can only be connected to SIPRNET (google it) and the Toughbooks are never connected to any network. That's it. No crazy combination case locks, no biometric devices, no odd software. They all run Windows for crying out loud.
If it is your job to configure a computer to the equivalent of DoD's Secret classification (I know you don't work for DoD or you'd already have people showing you how), I'd recommend getting whatever kind of computer will fit your needs.
Then start looking at writing mountains of policies. The first thing you have to do is restrict physical access. This can be done by putting the machine in a locked room with no windows. A laptop would be even easier... just get a GSA-approved safe and keep it in there when it's not in use. Obviously, you would never, ever, ever connect it to any network, period. All the data going in and out should be on CDRs or USB keys and should be accountable somehow. Figure out who needs to have access to it and if they can be trusted. Be sure to emphasize that failure to follow proper security procedures is grounds for immediate termination, whether any information was compromised or not. Ensure that whenever the machine is used, there are never less than two people present. Create an emergency checklist of what to do if the building catches fire, for instance.
That's all I can think of off the top of my head, you'll probably be able to envision a lot more with some careful thought. Good luck.
Any of you /.'ers ever study art history? Here is a little lesson about fraud.
/. mods. You just got social engineered.
In the Art world when a piece of Art has a past where the time record has some glitches in it (Read: unaccountable) it is automatically considered a fraud. When things don't have a timeline, like this guys posting record here and the fact that his myspace profile says he is 19, you gotta know something is up.
Congratulations though
