Re: Spectrum VS5030 disk encryption query

Hi all

That's all very helpful thank you. I guess disk based encryption which we
don't have now is going to be better than no encryption at all.

The query I raisede with our security folks was, should we turn on this SAN
encryption or not and that created a bit of a fire storm of responses which
led to my query. I can understand how without adequate controls at the
application or OS level data is still vulnerable but implementing disk
based encryption over no encryption at all has got to be a good start.

Disk based encryption is relatively free, implementing at the application
level is going to be a lot more complex and require significantly more
discussion within the organization. I don't see why you can't have one
without the other.

Thanks

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.
