TSA to Contractors - Encrypt Your Laptops 132

eweekhickins writes "After two laptops were lost containing the personal data of 3,900+ truckers who handle HAZMATs, the Transportation Security Administration has ordered its contractors to encrypt any and all data. 'After the second theft or loss, the TSA conducted an IT forensic investigation that ascertained that the (previously) deleted information could be retrieved if a thief had the proper training. "So even though [there's only a] small chance of [the data being misused], we did notify all affected individuals and advised them of what steps to take to protect themselves, and we mandated that contractors need to encrypt any and all data in addition to any deletion procedures that might be in place," Davis said.'"

      It's more likely it was pitched, but either for cost or time, management probably shot it down. Never mind there've been high profile laptops missing all over, like the VA one. Being naive, I would wager that the IT department would like to lock down the systems as tight as possible (I know I would) but are being thwarted by management becaue it'd make things too hard, too different, or cost too much.

      It's always after the sole data server blows up that they decide "oh, guess that backup option would've been worthwhile." (Had this happen too. Financial data, customer data, and no paper trail. But the tape drive cost 'too much'.)

        I keep wondering, if the data is that sensitive, IT departments should have it physically never leave the data center. Instead, offer different means of access via secure means, such as Remote Desktop, ssh, a secure webapp available after connecting to a VPN, or some other means of accessing the data and gathering reports from remote. Keep the data available, but have it physically reside in the (relatively) secure environment of the data center.

        If someone needs offline access (for example in a remote location with no Internet access), that is a different story, but in a number of laptop theft cases, there is no real reason the info is physically sitting on the laptop.

        Of course, this won't prevent an employee from doing an export of all the tables to their laptop, but having the sensitive data behind a username, password, and a SecurID token means that the losses due to a stolen laptop will be minimal. Add a decent FDE program (BitLocker is decent because it doesn't get in the way of users, provided they can access their user), and a laptop loss can be written off as "just" hardware.

        A number of Dell laptops and desktops have the ability to have CompuTrace installed in the BIOS. This is another good tool to help find stolen goods.

        By using the tools out there, from WDE, to having data physically residing on a different location (although there are cases where this isn't possible), to CompuTrace, damage done from a stolen laptop can be greatly mitigated.

      • Of course it already is policy, every IT dept says not to write down passwords but it still happens. The real problem is a lack of security auditing. A flawless policy is useless if its not enforced. Someone needs to go verify that there aren't sticky notes with passwords on the computer, that the drive is encrypted.

        Of course "inspectors" are usually associated with bureacracy and corruption. However TSA is already built around useless bureacracy not effectiveness, so how can it hurt.

This is often due to setting too many rules for which characters the password can contain, and making the user change their password too often. The other problem is, is that people have to remember too many passwords. Different passwords for their home computer, banking website, gmail, office computer, debit PIN, and probably about 5 other things.

    You steal a laptop. If you're not a complete dimwit, you first of all check what you got. So you boot the thing up and notice that you have a government laptop in your hands.

    Question for 100: Do you want to know what's on it? Let's even assume you don't know jack about computers, but do you want to know what's on the box?

    Now, it's fairly trivial to get information out of a hard drive and restore deleted information (unless it's been overwritten, where it becomes less trivial). A halfway informed person with a bit of knowledge is enough, you don't need a forensic expert. All you need is the usual program(s), downloadable at leisure. And presto, instant information recovery.

    The question is not whether information can be gained from the laptop, the only question is whether the thief has the brains to use it. That he has access to it without any hassle is a given. The only thing that matters is whether he knows a fence for information rather than just hardware.

    I use Truecrypt [truecrypt.org] to encrypt a partition on a drive and store all of my documents there. It's transparent to the user, once you've mounted your volume(s) and it's pretty danged fast, too. You can do encryption with Twofish, Serpent and AES or a cascading combination of them. Pretty damned secure, opensource and free.

    You can even encrypt a whole device. If you do that, it just looks like a blank volume and a thief won't even know there is data on the volume to be decrypted.

        Boot locking, as in setting a hard disk password in the security section of BIOS?

        Setting a hard disk password (all IDE and SATA hard disks made since 2001 or so have the ability to require a password before access is granted) is decent security, however how truly secure it is, is debatable. Some people have claimed there are backdoors and universal passwords, others have claimed that only a low level recovery service that has the clean room and tools to look at the actual bits stored on the platters can ac

      TrueCrypt is an excellent program, the devs have put a lot of thought into every aspect of security. I use it for encrypting external drive volumes completely so if someone does a smash and grab on my stuff, they will end up with hardware, but the data is protected by a passphrase and a keyfile stored on the (WDE encrypted, using a hardware token) boot drive.

      The biggest thing to remember with TrueCrypt, if you lose the first 1024k or so of an encrypted volume, you have completely lost the volume because the first part contains the encryption key (or keys) for the rest of the data. ALWAYS back up the volume headers (they are encrypted with the same mechanism as the volume itself, so they just need to be stored safely) of all critical volumes.

      Of course there will be people saying that "I don't use encryption programs, I have nothing to hide." That is analogous to saying "Don't have a front door as you might has something to hide." Its not the governments these programs are for (most governments can obtain the decryption key via other means including a rubber hose), its thieves. These days, TrueCrypt and other security programs are highly necessary to keep a $1000 laptop from becoming a loss of many thousands in ID theft.

      When you view your documents, how do you go about making sure that none of the data in them gets shoved into virtual memory?
    • Something funny happened with my Truecrypt today.

      I agree with the parent and sibling postings that Truecrypt is a great program to have, and I use it all the time. I set all my Truecrypt volume sizes to equal 650MB, so that I can burn it to CD-ROM easily (e.g. archived copies of my finances, etc.). The fixed size means that someday I can pick a few of my Truecrypt volumes to include a hidden volume [truecrypt.org], but most of them won't have hidden volumes --but any attacker can go spin his wheels trying to look for a h

      So you've stored your documents on an encrypted partition. What happens to all the "~wrdxxxx.tmp" temp files then? Generally they're in your user or windows's temp directories and probably have all sorts of recoverable juicy info. I'm not convinced that anything other than full disk encryption (pref in hardware) is really worth the effort...

    Most Thinkpads support something like Full Disk Encryption. Password in the BIOS, and you can't boot without it. The disk is literally unusable without the password.

    My gig at I%$&#, they had me write my FDE password down and give it to the nice Systems tech. That way, when I left, they could recover the disk and reissue the machine after the usual shredding and wiping.

    Without it, they would have to throw out the drive and buy a new one.

    And yes, you need to remember your password. This you write down and leave at home, or with the Keymaster in the office, or your boss.

    Honestly, this is not that hard.

    • Thats just an ATA password, as enclosed with the ATA spec. That means without that password, the HD motor just doesnt start up.

      All you need is disk microscopy to recover data. Just send it offshore to a semi-legitimate firm for data restoration on backup DVDs. It'll cost a thousand or so.
      • On the Thinkpad I used, the FDE password was not just an ATA password. the drive it self was encrypted with this, and not having it meant the drive was unreadable on any system.

        I may have mislead you. It isn't a BIOS password, it's a pre-boot password. No password, no boot. It just cycles through another POST and askes for the password after the retries wear out.

        If it were just an ATA password, what good would that do?
        • An ATA password is kept on a certain part of the disk that is normally inaccessible. The HD will not work if you dont provide that ATA password, whether or not you switch machines with that HD.

      The disk is literally unusable without the password.
      I consider that to be a design flaw. It should be possible to change the password without knowing the old one, but of course doing so would mean all data on the disk were lost. But are you really sure the disk encrypted the data? And could you verify the quality of the encryption? Maybe flashing a new firmware on the drive would have allowed you to bypass the protection.

        My understanding (and we grilled our supervisor on this one - he was good) is that flashing the drive would REQUIRE the password. But even if it didn't, the data is encrypted. If the password is on the drive firmware, flashing it would lose the password and woops, no data.

        This is the hardware encryption scheme - supposedly, even if you put the drive in another Thinkpad, that chip has a different hardware key and even the right password won't decrypt. So it encrypts data onto the drive.

    In my opinion, any company, corporation, organization or government entity that misplaces (through loss or theft) sensitive financial data should be responsible for paying for identity theft coverage for as long as the potentially affected individuals live.

    • Seeing has how the mere act of encrypting data has been used in court to establish guilt

      Has it been? The only case I've heard of that being alleged was one here in Minnesota, where the prosecution said that somebody who committed whatever crime would almost certainly have an encryption program. It was of no more significance, than, say, car color. If a crime is committed, and the getaway car is described as a blue compact, then if I come under suspicion the fact that I drive a blue compact is relevant

        I misspoke, slightly, in my original post. From one of several news articles:

        A Minnesota appeals court has ruled that the presence of encryption software on a computer may be viewed as evidence of criminal intent.
        If the mere presence of encryption software can be used as evidence of criminal intent, it's unethical (and, arguably, criminal) for the TSA to require contractors to encrypt the data on their computers.
