Ask Slashdot: Secure DropBox Alternative For a Small Business?

First time accepted submitter MrClappy writes "I manage the network for a defense contractor that needs a cloud-based storage service and am having a lot of trouble finding an appropriate solution that meets our requirements. We are currently using DropBox and I am terrified of seeing another data leak like last year. Some of our data is classified under International Traffic in Arms Regulations (ITAR) which requires that all data to remain inside the US, including any cloud storage or redundant backups. We tried using Box as a more secure replacement but ended up canceling the service due to lack of functionality; 40,000 file sync limit, Linux-based domain controller compatibility issues and the fact that the sync application does not work while our computers are locked (which is an explicit policy for my users). I've been calling different companies and just can't seem to find a decent solution. Unless I'm severely missing something, I'm just blown away that no one offers this functionality with today's tech capabilities. Am I wrong?"

      For something Dropbox-like in UI that you can point to your own servers, some options are:

      * Git-Annex Assistant: Despite its name, git is sort of an implementation detail you can ignore. It doesn't actually revision-control all your files, so you don't get huge bloat with binary files that are edited. One nice thing it does is integrate syncing with offline storage, so you can e.g. set up a remote server to sync to live, *and* set up a USB-connected hard drive to sync to when it's attached. When the USB drive is offline git-annex will still remember what files were on it.

      * Sparkleshare: a front-end that does version-control all your files, which might be preferable if you are sharing small-ish files where you might want to recover a previous version (e.g., text documents). Less good than Git-Annex Assistant if you're sharing huge media files, possibly better if you aren't.

      As many posters indicated in their comments, compliance is not even checked against your arbitrary list of technical measures. It is checked against an approved list of measures and actions that you are supposed to have and perform.

      Good encryption would be a solution. You could have a server in North Korea and safely store all the secrets of portable nukes there, as long as they are well encrypted.

      But the devil is in details. What does it mean "well encrypted?" What is even the criteria for "wellness" of your encryption? Would it be OK if I use ROT13? Ok, perhaps not. What if I use AES256? Now you are happy. Right? No, wrong - because I used a key that consists of all zeros. Or ones. Or something equally trivial.

      But let's imagine you have a secure key. You used /dev/random, and it is random enough. Is it secure now? No, it isn't. You now have a known plaintext attack. AES may prevent you from reversing the key, but it still a block cipher - and many technical documents have similarities that can be exploited. Unless salted, every block of same plaintext will produce the same ciphertext. This is already a leak of data. Is it important? Maybe not. But there was no such leak before, and now there is a foothold. Can you guarantee that it won't get worse? Your adversary has all the resources of the state (albeit a poor one) and they are not constrained as much as you are.

      This is why you never invent your own cryptosystem. NSA does that, and they approve and provide cryptosystems for various end users. If you can get NSA to approve a cryptosystem for your setup, you are golden. But chances of that are not very good. If you start building your own, nobody is even going to check what you did. If it is not approved, it's not good. DSS workers are not cryptographers; even most of NSA personnel are not cryptographers (as we know now.) It takes an inordinate amount of effort to approve a cryptosystem for a particular use. One can have a good algorithm that is implemented with a small bug, and that bug turns it from unbreakable to reversable in milliseconds. Cryptographers know what to watch for, and even they make mistakes sometimes. Can you get away with a crypto library that you downloaded from Internet? I don't think so. It may be perfectly secure, but that's not what you will be evaluated against.

      ITAR is a not a security clearance classification. It's an export control classification.

      This is more than a little important because it means no "foreign persons" can access the data. Inside or outside the US. You can let a US person in France see the data, for example. Foreign persons is defined in 120.16 of ITAR. Check http://pmddtc.state.gov/regulations_laws/documents/official_itar/2012/ITAR_Part_120.pdf (listed as Page 467)

      Basically, you can't give any ITAR data to any foreign person. If the foreign person could access the data, even if they do not, you're still breaking the law. There's a presumption of guilt if you say, leave ITAR data on a public share in your company, where foreign nationals could have accessed it. Do not put ITAR data on any disk you don't control unless it's reasonable that the provider cannot access it (ie encrypted).

      If DropBox has or had one foreign national that could access your account (which is likely) and the files were unencrypted, you already committed a federal crime and should give a voluntary disclosure to DDTC They'll likely give you a slap on the wrist or more likely do nothing, especially if voluntarily disclose and implement a solution to fix the problem.

You may not export the data without a permit, but you don't need to control it specifically within the US.
