Encryption Should Be Default for Sensitive Data

Here we go again. Sensitive, personal information stolen -- and the files weren't encrypted. The negligent organization this time? NASA. Yes, the very same NASA that defeated a legal challenge last year to intrusive background checks, based in part on privacy concerns:

Justice Alito said that the plaintiffs' privacy concerns should be allayed because the Privacy Act imposes strict restrictions on how the government could use the information it obtained.

Nothing stopped it, however, from leaving personal information, in unencrypted form, on a laptop in a parked car. That's where the thieves found it. Data on 10,000 NASA employees, including social security numbers, dates of birth, and -- yes -- some of that background check information the Supreme Court was so confident could be protected.

But this is beyond a joke. Only last week, I wrote about the theft of hundreds of thousands of unencrypted records from the South Carolina Department of Revenue. Do people think encryption is something that exists only in spy novels? Trying to get states to focus on adequate security measures may be like herding cats, but at the level of federal agencies, somebody needs to take ownership of this problem.

We have a seemingly intractable challenge with trusted identities in cyberspace -- ensuring that only the right people get to look at files. But we could, at least, encrypt the sensitive data contained therein. Encryption isn't perfect; keys can be stolen. But it's better than no encryption at all.

One argument against encryption, of course -- especially full disk encryption -- is cost. Some analysts maintain that the benefit of encryption in mitigating damage from data breaches more than justifies the expenditure involved. Others advocate encrypting data only when necessary.

In my book, when sensitive data is going to be placed on a laptop, and taken outside the security perimeter, it's necessary.

What other data from federal agencies is sitting unattended in the backs of cars? Remember, we still have a rump of Republican senators filibustering attempts to pass cybersecurity standards for the national grid. To the extent the grid is in private hands, security is unsupervised; to the extent it's in the hands of federal agencies -- well, given this example from NASA, we might as well give up.

If we're not going to give up, however, what we need are mandatory security benchmarks, at least for government departments and agencies. It's not impossible: FedRAMP (the Federal Risk and Management Program) has set standards for federal use of cloud computing services.

I'm asking for something more basic. Rules on the storage, distribution, and use of defined types of sensitive data, together with sanctions if the rules are broken. Once the federal government has standards in place, it can engage again in the difficult task of persuading the private sector to adopt standards at least as stringent.

I would say, as we all know, file encryption can be done through free PGP implementation. Drive encryption is TrueCrypt or BitLocker on Windows, they are free too. There might be overhead coming if you do encryption on root drives but on data drives benefits outweighs the overhead.

Agree. I have been using GnuPG for long time, easy to implement and quite effective when you want to share data with external entities. There is no reason why we do not encrypt everything that leaves our data center.

@Kim - I cannot find anything about the Massachusetts hard-drive purchase incident online.  Maybe someone paid to get this story sanitized from the Internet before the campaign began, or maybe I'm just not looking in the right place.  If you find a link, can you post it.

I haven't read the whole thing, but I think encryption software (and presumably the software to decrypt) is on the restricted list....

That surprises me.  I'm sure people travel with encrypted laptops all the time.  Is it a widespread problem?

That if you travel abroad with an encrypted hard drive, that you're not exposing yourself to liability of exporting banned technology. Some encryption is legally prohibited from export....

Amen to that! Encryption can be the difference between being sued to thriving. I have no idea on what NASA was thinking since a technological company should know better than that. However, with that being said it does seem like those who know better are the worse offenders of not following the rules. It makes the statement "do as I say and not what I do" to be very true. Hopefully whoever was behind the lack of encryption will face the music over this big brouhaha at last.

Edward Snowden was so convinced that the Prism program involved secretive surveillance through Internet backdoors that he walked out on his job and his girlfriend, spoke to the media, and resigned himself to jail, or worse. It turns out, he might just be wrong.

Extending existing US wiretap laws to give federal agencies easier backdoor access to Internet communications -- especially real-time P2P services like VoIP -- will give, not only aid and comfort, but also technical assistance, to the country's enemies. Not to mention cyberthieves.

Law Will Define Next-Gen Privacy

The plan for unmanned police drones to patrol traffic and other city conditions in Seattle has sparked a new set of legal concerns about privacy. Law traditionally lags technology, but we can expect now to see a new round of activity in the courts as legal definitions begin to emerge on what "next-gen privacy" will look like.

NSA Leaks Shine Spotlight on Perils of Contractor Partnerships
Jason Mick
The US National Security Agency learned the
hard way that it can be dangerous to give a contractor too much money and access, with too little scrutiny. The NSA and other government agencies hire tens of thousands of contractors a year to analyze data. Edward Snowden -- who revealed himself as the NSA leaker after fleeing the country -- was one such contractor, reportedly holding a $122,000 salaried position at Booz Allen Hamilton at the time of his departure.
