When Data Goes Missing Will You Even Know?

Lam1969 writes "Jack Gold says IT shops may have a huge problem on their hands, and probably don't know even know about it. The problem is USB flash drives, which he predicts will probably reach 10 GB in capacity in three years, and the lack of policies to guide use of them by employees. From the article: 'With more and more employees using flash drives, smart phones with Secure Digital memory cards, portable hard drives, etc., the likelihood of companies actually knowing about all instances of data loss is declining rapidly. And as a result, the possibility of companies breaking laws, whether for data-loss disclosure or regulatory compliance, is growing dramatically.' Gold predicts 'at least one publicized major case of unencrypted data loss from a portable device' in the next year, which will result in many companies banning these kinds of devices."

    From the slashdot post:

    The problem is USB flash drives
    While there is truth to this, it is not a new truth and it is not the complete truth. It's one more mechanism for "losing" data but it's not the first and it won't be the last.

    It's an effective mechanism for moving large volumes of data, but it's not the only mechanism.

    Corporate espionage and theft has and will continue to exist. USB drives are just one more aspect. While there may be some "exposure" and scandal soon about some USB drive falling into the wrong hands I doubt it will surpass any of the recent scandals (lost tapes and customer data).

    Unfortunately, I'm guessing the article is correct in its prediction: "It is highly likely that within the next year, we will see at least one publicized major case of unencrypted data loss from a portable device. Afterward, a lot of companies will ban such devices". That would be a knee jerk reaction and counter productive but I'm already seeing it on so many other levels, e.g.,

    • restricted e-mail (filtered to death)
    • blocked IM
    • key logging

    among many others. I still think the greatest exposures are social engineering... and the paranoia around security policies don't address that. Sigh

    (And, besides, isn't the RIAA is working on a solution to apply DRM to USB drives too? ) ;-)

      My company already has a policy banning them. Using a USB drive at work w/o permission will get your ass fired.

      The company that I work for recently had a laptop stolen. It had personnel information for a large large number of employees (greater than ten thousand) and may or may not have been properly protected. I think that qualifies as pretty serious data loss, and it didn't need a flash drive to happen.

      Will it be more prevalent? Maybe. But it already happens. Now, the question is, is there a program that can encrypt/decrypt an entire (relatively) small drive with some sort of key system or something? I think that will be the most logical step to protect small drives like these.

        That is data loss (the notebook), assuming no backup. The idea of removing a _copy_ of the data is not loss, it is theft. A bit of distinction but important. I will notice data loss, not likely to notice the theft though.
        -nB
        • I see it not so much as "loss" or "theft". Both terms imply that the data no longer exists where it is supposed to be. Loss means it's gone completely, theft that it has been taken in a "move" like scenario rather than merely copied. It seems a more appropriate term for this type of situation would imply the existence of the data in it's original location, and an unauthorized copy in an unknown location. This is much harder to detect because obviously, the original is still in tact -- absence of the data is a big clue something is amiss. Maybe the best term is simply "unathorized copy". In any case, the title mislead me -- I was thinking about HD corruption of small areas leaving me unaware that some of my data may go missing.

      "It is highly likely that within the next year, we will see at least one publicized major case of unencrypted data loss from a portable device. Afterward, a lot of companies will ban such devices"

      No need for "afterward". Most companies that are extremely interested in protecting data (such as a large .com in Seattle for which I have worked) have banned such devices for years. No media may be used to transport company data except that which is explicitly allowed. In addition, no computer wireless devices of any sort (keyboard, mouse) may be used on company machines for security reasons. I'm sure that there are a lot of other similar rules, too, and all for good reason.

      It doesn't take a smart company to figure out that you don't want Billing.mdb on a floppy. USB is really no different. :)

        Ok, Jack Gold's put a slightly more useful spin on it by talking about accidentally lost data as opposed to deliberately stolen data, but it's still the same old hash with scaremongering about USBs.
        • Briefcases get lost all the time, and briefcases have been large enough to contain sensitive information for decades now. Keychains also get lost on occasion, and especially for small businesses that's often enough to get in the building at night or steal a company truck.
        • Yellow Sticky Notes with your IP address and VPN password fit in your pocket just fine, and DSL means that people can suck up your data even faster than when we used to use Yellow Sticky Notes to carry modem phone numbers and dialup passwords.
        • Documents that are actually important are usually 1-100 pages long. You can store them on mashed-up dead trees if you avoid spilling coffee on them. Them newfangled USB thingies hold a lot of data, but back when we carried 3.5" floppy disks 20 miles through the snow uphill both ways , Microsoft Office wasn't as bloated, so a zipfile of The Secret Plans still usually fit in your pocket. That's not the same as carrying out the whole blueprints for your next chip in your pocket, but mini-CDs do pretty well - they're certainly enough to carry the HR personnel database home.
        • DVDs and CDROMs fit pretty neatly into briefcases, and most newer PCs have at least a CD burner, so you can still carry the chip blueprints home.
        • Laptops are easy to carry, and go missing all the time. The San Francisco Police aren't very good at recovering them even when they've got them in their evidence room and the thief in custody; your mileage may vary :-) And unlike keyrings and regular briefcases, laptops have obvious resale value so they're more attractive to thieves.
        • RM-05 removable disk packs are a bit big to fit in your briefcase, but magtapes fit just fine, and before magtapes we had ASR-33 paper-tape, which works just fine for carrying the Numerical Control tape that tells the milling machine how to cut your submarine-propeller plans.
        • Mainframes with Greenscreen 3270s are much less portable, but back when I worked for The Big Phone Company they were worried about people carrying computer printouts home, and they checked our briefcases on the way out the door of buildings that handled sensitive information.
        But yes, within the next couple of years, somebody's going to have a USB keyring/wristwatch/Walkperson/iPod/Pseudopod/somet hing get lost or stolen with sensitive information on it, and the press probably will fly off the handle telling us they told us so, and that we need to take precautions we've never taken before with laptops or CDROMs or whatever, and that's probably going to include silly bureaucrat tricks instead of getting major operating systems to have convenient encrypted file system support (and remember, "major operating systems" includes the OS's for portable music players and not just the computers they plug into.

    When I see the fact that a USB storage device has been inserted into a workstation or server, I question what (and who) did what.

    The log files don't lie!

    Of course if you can't find them, then it doesn't matter, does it? Does WinXX create a log file of USB insertion - damned if I know!

    "I had to invade the owner's privacy to see what I could discover from the content of the files."

    Wouldn't this be accessing files that you were not granted access to? Isn't this a crime in several US states, and is it really a good idea to admit to it in a column with your picture and name at the top?

    Just curious if the 'Good Samaritan' is putting himself at risk (and if it was curiosity or a desire to return the property that was the motivation).

    Which will solve exactly nothing. What are you going to do, search everyone as they enter and leave the building? If you want to limit data theft, limit access to huge amount of data in the first place. That eliminates the risk to any new technology to get the data offsite.

    I know of several companies which have filled in all the USB/firewire ports on most of the computers with epoxy. Only people who actually have a real need for devices using those ports have working USB/firewire (there are no floppies or CD/DVD burners in 'regular' staff machines either)

      Funny,
      As a dev (and with tons of confidential and privlidged info on my computer) I am specifically instructed to take my notebook home every night. It is considered part of our business continuity plan. Not only that but this is a large multinational corp, not a mom and pop shop. That said, the drive is encrypted, and security policies are in place for communication back to the office when I'm away (2048 bit RSA VPN).

      What it boils down to is this:
      My employer knows that if I want to steal data I can do it. Even if it comes down to hand transcription of one memorized line of code per day. So they trust me and provide me a hardened notebook to do my work on. Even if it is lost the data will not be compromized till it's likely to be useless anyway.

          Not that we had anything that critical or sensitive where I worked, but I always found it silly to bar someone from bringing in their laptop.

          There is logic in it, if you think about it from a "corporate IT putting out a blanket rule" perspective.

          That rule that applies to you also applies to Sharon, a blonde hairdresser by trade who's just taken a second job in the bank to supplement her income.

          Sharon has a laptop of her own, and wants to bring it on so she can get on the Internet in her lunch hour - after all, she's not allowed to use company computers for personal web surfing.

          Unlike yourself, Sharon's never heard of virus scanning (well, she has, but she was checked by her doctor when she started seeing her new boyfriend, so that's all right). She thinks spyware is the name of the next James Bond film.

          Now the bank has a number of business critical systems running Windows. Perhaps unsurprisingly, Auto Update is disabled. This is because, despite Microsoft's best efforts, such updates occasionally break things. Instead, updates are trialled on a test network and then, following a change control procedure, are applied. This procedure takes a while, so at any one time most of the critical Windows systems can be a good few weeks behind on patches. This rises when testing reveals problems, and it rises even further when the system in question was built and maintained by an outside company - their update, assuming they provide one in a reasonable timescale, is subject to the same test requirements and change control as a Microsoft update.

          Meanwhile, Sharon's PC, which is swimming in spyware, trojans and viruses, is merrily scanning the network for vulnerabilities.

          I don't think I need to spell out the rest...

          Of course, many motherboards have a USB connection where you can plug a slot-based set of USB outlets. If you're already opening the case, that's all you need.

          And USB, I think, is only 4 wires... if the plug is epoxied, just open the case and hotwire your own outlet.

          Somone else already mentioned installing a 2nd harddrive to copy data. And one could also install a $20 USB/Firewire card in one of the PCI slots.

          That leaves filling the whole computer with epoxy. Great, you've turned your PC into a commodore 64. I hope you don't have to fix it!

          People just have to accept that if a person has physical access to the machine, they can compromise it.

    It's been present ever since Windows 2000 - if a company is worried about data loss via USB drives and the like, it's possible to disable access to USB drives using regular Windows security templates.

    What the article probably meant to say is that sloppy security practices, combined with increasing personal storage, increases the risk of unknown data loss.

    You can lock down a Windows box just fine against casual and accidental leaks if you know what you're doing, and you have a corporate policy to enforce. You can even prevent deliberate attempts at data theft, if you really want to be a hardass.

    Auditing of a filesystem is the best way to go here, IMHO. Drives are getting bigger, so capacity for log storage grows too. Currently you can set most filesystems that have granular security to audit file access, writing, creation and deletion. Perhaps there is some way to adit target actions ("copied to removable drive X", "opened by Microsoft Word") that will be developed eventually. Personally, I log access to important files as a matter of habit (mostly with NTFS). I've also found that the bigwig execs love it when you tell them you can see who tried to look in their directory.

    The article is not about people stealing sensitive data from their workplace using their USB drives. The article is about people losing data, because they've lost the USB drive they had it stored on.

    Is the issue called trust. Specifically, towards people on the inside of your organization.

    It all boils down to "Do you trust your employees"?

    There are businesses that do, and there are those that don't.

    Those that do work on the assumption an employee will not do anything to harm the business intentionally - take a file he is exposed to during work and transfer it somewhere outside the organization.

    Hence, it will not take all measures required to prevent him from doing so.

    A business that does worry about such things will - What you carry will be checked at the door. Your PC will be locked (the case, physically locked). No Floppy, CD-R, USB, no means to connect media you bring from home. Internet access will be so restricted you wouldn't even be able to encapsulate an SSH tunnel over DNS packets you kindly ask your DNS server/proxy to send for you. And so forth.

    Pointing at a business where everyone has web access and a dell sitting on his desk with 2 USB ports looking at him and saying "Hey, this guy can copy a confidential word document on the USB key" is hardly news, doesn't bother anyone in the first type of organization, and usually a non-issue in the second (which would have taken excessive measures to prevent exactly this kind of thing).

    Nothing to see here, move along.

    For a company to function, many employees of the company have to have access to the company's data. All of them, if they are inclined to do so, can copy it. Heck, many of them can sabotage it, and destroy the company.

    Guess what the company can do about it? It can stop treating the employees as shit. Especially stop pretending that the company is some amorphous entity that makes its owners/shareholders entitled to profit, and can impose idiotic demands and shitty conditions and pitiful pay on everyone else in it. Employees do their work, this is why they have access to company's things. Nothing, ever, happened in a company without some employees making it happen, so if any of you wonder, why people can destroy your precious company, keep it in minds -- THIS IS BECAUSE THOSE PEOPLE ARE THE COMPANY.

    There is nothing wrong with avoiding overbroad access where it isn't necessary for things to work, however there is no way to make any company "secure" from the very people whose only responsibility is to keep things running. Don't piss them off, and remember that you didn't become Presidents, CEOs and VPs by understanding how to operate anything that makes your company what it is. Every time you eat your lunch, think how many people you have abused today, and what will happen if any of them will press a few buttons.

    We had a client at one of my previous jobs who explicity banned USB jump drives from the workstations they would be using. So, after a few seconds of head scratching on how to do this I:

    * Disconnected the USB ports and,
    * Disabled them in the OS and,
    * Removed the USB flash device .inf file that Windows provides and,
    * Padlocked the case shut.

    It takes a few moments per machine and should be part of the standard build for any business that cares about their data.

      To think that malicious employees waited until flash drives to steal data! Dear god, what about paper printouts, hard drives, e-mail, and (dare I say it?) floppy disks?!?

      It isn't the theft of data that TFA is really concerend about.

      The real threat comes from actual LOST data. With portable storage media getting bigger and bigger, more and more data can be put on it. Including massive amounts of spread sheets and even databases. (I worked for one company that insisted on keeping a sensitive database on USB keys, to be sneaker-netted around to whoever needed it).

      Top that off with more and more USB keys floating around the office. Sure, right now, not every employee has one. Or, at best, every employee has just one. But it is becoming more and more prevellant to have "unowned" keys. In other words, a company buys a crapload, and people just grab whichever key is available at the moment to use.

      Soon, people will treat USB keys like they treat floppy disks; there'll be a big pile of them, and employees will just grab one as they need it.

      Because of this causal attitude towards USB keys, it'll become near impossible to track all the data. Employee X copies Spread Sheet A onto a key, takes it home to work on it, brings it back, and tosses the key back in the pile. You now have an unaccounted for instance of that data. Each time an employee does that, you have more and more instances of data that are unaccounted for.

      There's no guarentee that the employee will blank out the key. There's no way of tracking which data is on which key. So an employee might check out a key that has data on it that isn't theirs. There might be hundred of files on the key. Who knows. They don't. They won't care, either. They'll just copy thier files over, work on them, copy them back.

      So, each key has tons of data on it. If someone were to ask the CFO "Show me all copies of Sensitive Spread Sheet 5", they couldn't.

      Now, one employee checks out a key. They treat it just as casually as they would a floppy disk. They lose it somewhere. (Falls out of their pocket, gets left on the bus, etc). Now, a floppy disk might have just a tiny amount of information on it. A few documents. A couple spreadsheets. A USB key could have an entire database! Someone picks it up, and suddenly has the bank information for all the company's employees...

      That's the big issue there. Not that employees will sneak data away on USB keys (though that is a concern, too), but that employees will be too casual with large amounts of data and quite literally LOSE it.
