Privacy In The Clouds….

I’m not sure why this never got discussed before, but suddenly, with the “shocking” revelation that the government has been collecting data from the cloud in bulk, the concept of “Privacy” is on everone’s mind.

I’m telling you.  Anyone who thought their “Cloud” storage was secure from prying eyes has deluded themselves with visions of puppy-dogs and unicorns.

Personally I’m not worried about it.  I never expected anything I put in the cloud to be private anyway.

Bottom line, the internet wasn’t designed to be secure, it was designed to be redundant, transparent, resilient.  But when you send information out “to the cloud” you’re trusting your electronic information to equipment that other people own/control, and as such have no guarantee as to the security of your data.

I’ve gotten into my share of “discussions” on news message boards when Edward Snowden broke the news that the NSA was spying on Americans… (Duh)   When I tell people “I don’t care” and “I assumed it was anyway” I got lambasted.

So how *DO* you secure your data?

Endpoint Encryption

The only way to be reasonably sure that your data is secure in transit is to implement endpoint encryption.  Where you have an encryption device on the source, another on the target, and if you *REALLY* want to be secure, you’ve HAND CARRIED your encryption keys from Point-A to Point-B..  (Sending your private key over the email is, by definition, stupid.)

Then, you’re only at the mercy of Barracuda, Cisco, EMC, or whomever built your encryption appliance.  Here’s a thought though… Do you know there is no back-door to decrypt data?  How do you?  the code that runs on these appliances are proprietary, you don’t know ANYTHING about the internal code, and I’m sure none of the above will release the source-code to you for inspection, (nor do you have any reasonable assurance that the source code you’re shown is what’s compiled and running on your encryption appliance).  Again, it’s a matter of trust, but there is always the possibility.

Closed System

This is the only real chance for security.  A campus-wide, closed system, with no external connection to the internet, optical (as opposed to copper) connections between buildings, etc. Is the only REAL chance for security.  But is it worth it?

I had a colleague when I worked for the student loan company (thankfully defunct) that used to say that the best way to secure a system was to turn it off.  He probably wasn’t far from the truth.  When I took my Windows NT MCP certification course (dating myself huh?) my instructor told us that Windows NT was the most secure operating system on the planet, provided the computer wasn’t connected to a network.  (Then, presumably, all bets were off)

In Conclusion, as long as you know that, the more of your application/data you put in the “cloud” the more vulnerable you are to plundering, not to mention outages that are completely out of your control (right Amazon AWS?)

If you keep your data in-house, under your control, not only do you have a neck to choke when you’re system goes down, but you can be reasonably sure of it’s security.

(Unless you plug it into the internet – then all bets are off)
