Re: Spectrum VS5030 disk encryption query

Hi Laurence,

Take a look at this PDF https://www.ibm.com/support/pages/sites/default/files/inline-files/Spectrum_Virtualize_Encryption_V1.pdf

When you use disk encryption on the device side you prevent from reading data if someone steals your disks.

But...

PCI Requirement 3.4.1 states, “If disk encryption is used (rather than file or column-level database encryption), logical access must be managed separately and independently of native operating system authentication and access control mechanisms (for example, by not using local user account databases or general network login credentials). Decryption keys must not be associated with user accounts. This requirement applies in addition to all other PCI DSS encryption and key-management requirements.”

So... If you encrypt your data logical side (using something like FIELDPROC, Crypto Complete or nuBridges) you are on the right way.

We are about to implement SAN based encryption on our FS5030 SAN.

A comment was made by one of our security team who said while disk
encryption solves the problem of safe disk destruction it does not solve
access to data at rest if you have access to the LUN like a disk
administrator.

So OS level encryption is preferable.

I don't understand that. If data is encrypted and keys are managed locally
or via SKLM what tools would an administrator have to be able to view the
data? They might be able to delete the LUN but that hardly is access.
