TN BlueCross Encrypts All Data After 57 Disks Stolen 140

Posted by timothy from the best-practices-are-best-practice dept.
Lucas123 writes "After dozens of hard disk drives were stolen from a leased facility in Chattanooga, potentially exposing the personal data of more than 1 million customers, BlueCross decided to go the safe route: they spent $6 million to encrypt all stored data across their enterprise. The health insurer spent the past year encrypting nearly a petabyte of data on 1,000 Windows, AIX, SQL, VMware and Xen server hard drives; 6,000 workstations and removable media drives; as well as 136,000 tape backup volumes."

      You don't honestly think that the executives will end up with smaller bonuses as a result, do you? We all know that isn't how this game works.

      The company will cover these costs by raising premiums and/or reducing payments. It is very likely that the executives will see larger bonuses after this, as a self-congratulatory measure for "proactively correcting the situation".

        That's part of the fun right?

        I mean, as a customer, first you get screwed over by having your medical records out in public. Then the company gets fined and leverages that fine on its customers, thusly getting screwed a second time. Finally, costs are incurred for getting up to standards, and guess who is paying for those costs?

          Um, does anybody remember the password we used? Surely somebody wrote it down?

    • Which is a win for all. Executives can't get bonuses if there isn't a decent amount of income to the company, there can't be a good amount of income to the company if there aren't high revenues. There can't be high revenues if there isn't a supply of something people want that can be produced for at least slightly less than they are willing to pay for it. They wont be willing to pay for it if it's cost is higher than it's value to the individual.

      Why? Some states require that companies notify people when their data is stolen, as well as sometimes requiring identity theft protection (e.g., credit reports or alerts) or somesuch. This can get pretty expensive, and so it's probably cheaper to just encrypt everything. They're not being altruistic -- they're saving money. It wouldn't surprise me if some executive got a bonus for saving the company money ...

  • This entire effort might be useless if they're not using good encryption. Is there one master passphrase to bypass all of the encryption? Also, they make no mention of how they plan to prevent physical theft of data again just that 'Well this time I put a password on my data, take that thieves!'

      I wouldn't take the $6M and 5000 man hours as directly coupled. The actual press release says:

      BlueCross invested more than $6 million and 5,000 man-hours in the data encryption effort, which included:

      - 885 Terabytes of mass data storage
      - 1,000 Windows, AIX, SQL, VMWare and Xen server hard drives
      - 6,000 workstation hard drives and removable media drives
      - 25,000 voice call recordings per day
      - 136,000 volumes of backup tape

      The 5000 man hours may only reflect actual labor and not reflect all the hours of planning/scheduling etc. What ever hourly rate for labor double it for overhead, the cost of a person is about twice their salary, at $100/hour that's $1M in labor. Another 500K in planning. I have no clue what software they used but I'm pretty certain it wasn't a single package. Each system may well have required a different package + licenses + contractor time from the vendor. For example they may have had to out source the voice call recordings to who ever provides their phone system. I kind of doubt they slap all the recordings onto a single box and mass encrypt.

      They're a very distributed organization so there's going to be a *lot* of duplication of effort, they may have had to do the phone bit at hundreds of sites.

      I don't know if it could have been done for $3M or if $6M actually represents a relatively reasonable price compared to a lot of the $XXX Mllion dollar utter failure projects. It strikes me as fairly reasonable considering the scope of the problem and usefulness of the result (assuming it's not a $6M whitewash).

    • Even with the best commercially available encryption if someone steals the hardware storing the encrypted data they have all the time in the world to try and access it. The disks were in the possession of a 3rd party at the time of the theft so a security audit of their premises and security procedures might be in order to help raise awareness and prevent future incidents.

  • $6 million is pocket change to a company that has $5.2 billion in annual revenue. However, the true cost is really higher, as encrypting everything means that things like disk corruption are no longer repairable, lost passwords can't be reset without losing data, and the like. It'd be interesting to see just what the ongoing costs are.
