Re: Why does it matter if the data was encrypted?
@L174, WHAT!? Where are you getting your information?

The operating system only determines encryption levels (Protocols) if you let it, such as in a Windows Server where encryption can be controlled with a simple registry edit. I'd have to believe that these companies are not allowing this to happen and instead are using add on applications like OpenSSL or some other enterprise level data encryption software. Furthermore, if the data is encrypted you cannot access it without the proper keys for access, unless you have a few super-duper computers and more than a few years to hopefully stumble onto the correct key parings.

Although there may be places in the infrastructure where data may not be fully encrypted such as at the point where the application feeds a DB, but even that is very rare. Even rarer (I hope) would be an unencrypted DB holding sensitive data, hell, or ANY DATA. Any company that does not encrypt data in transit is stupid and deserves to be hacked.

Sensitive data that travels over a network are required to be securely encrypted from the point of data entry to the point where the data is processed if those companies are to be HIPPA, PCI or GLBA compliant.

Your comment leaves me to believe that you are either:

a)      Trolling

b)      Uninformed

c)       Not responsible for security on any level

or...

d)      Negligent

So you said, "Data Encryption is only helpful if a physical harddrive or machine is stolen, period."... what's the difference between a disc-image or the actual HDD? And a hacker isn't going after a HDD or an image because attempting to obtain either will or should set off alerts, he wants the DB and even that is going to be striped across a RAID. From what I remember about RAID, what you suggest is only "possible" if you remove a drive from a RAID – 0 or RAID – 1, and I don't believe Anthem is "Mom & Pop" enough for that configuration.

Re: Why does it matter if the data was encrypted?
I hate to be blunt, but your post belies a significant level of ignorance about major-business information security architecture and infrastructure.

 

Anthem almost certainly does not store production databases on "encrypted disks".

Also, the fact that a "database administrator noticed unauthorized queries" strongly suggests that if the data was encrypted, it's still encrypted and is (to the limits of the encryption strenght) just fine now.

 

When you understand enough to know why these statements are true, you'll understand why the rest of your post is largely incorrect as well.

Why does it matter if the data was encrypted?
Data Encryption is only helpful if a physical harddrive or machine is stolen, period. (Let that sink in for a minute)

While encryption is beneficial it is only usful in about 3% to 5% of data breach situations. (If you want to do a groundbreaking story you should focus on the fact that encryption offers very little protection in a hacking situation.)

Once a hacker has access to a running machine the data has already been decrypted by the Operating System or the running application and it is fully available to the hacker in the same decrypted format.

I will say it again, encryption is only helpful if a physical machine or harddrive has been stolen. So the big question was not "was the data encrypted' but how did the hackers gain access? By the way, I am willing to bet the data in this case was on an encrypted disk and as expected it did not help.
