Re: [openstack-dev] [nova][cinder][glance][osc][sdk] Image Encryption for OpenStack (proposal)

2018-10-15 Thread Matthew Oliver
Just an FYI, it doesn't solved cached images, but Swift does support at
rest encryption, so if using the Swift store backend you can at least know
your image on disk on the storage nodes would be safe.
We still need to add more functionality like key rotation, but we do
integrate with kmip sevices or barbican.

Still could be a good idea for other projects. I wasn't the one who wrote
the Swift at-rest encryption but happy to, probably badly, help answer
questions cause we might have some interesting lessons learned.

(excerpts from our image encryption spec below)

Problem description
===

An image, when uploaded to Glance or being created through Nova from an
existing server (VM), may contain sensitive information. The already
provided signature functionality only protects images against
alteration. Images may be stored on several hosts over long periods of
time. First and foremost this includes the image storage hosts of Glance
itself. Furthermore it might also involve caches on systems like compute
hosts. In conclusion they are exposed to a multitude of potential
scenarios involving different hosts with different access patterns and
attack surfaces. The OpenStack components involved in those scenarios do
not protect the confidentiality of image data. That’s why we propose the
introduction of an encrypted image format.

Use Cases
-

* A user wants to upload an image, which includes sensitive information.
To ensure the integrity of the image, a signature can be generated and
used for verification. Additionally, the user wants to protect the
confidentiality of the image data through encryption. The user generates
or uploads a key in the key manager (e.g. Barbican) and uses it to
encrypt the image locally using the OpenStack client (osc) when
uploading it. Consequently, the image stored on the Glance host is
encrypted.

* A user wants to create an image from an existing server with ephemeral
storage. This server may contain sensitive user data. The corresponding
compute host then generates the image based on the data of the ephemeral
storage disk. To protect the confidentiality of the data within the
image, the user wants Nova to also encrypt the image using a key from
the key manager, specified by its secret ID. Consequently, the image
stored on the Glance host is encrypted.

* A user wants to create a new server or volume based on an encrypted
image created by any of the use cases described above. The corresponding
compute or volume host has to be able to decrypt the image using the
symmetric key stored in the key manager and transform it into the
requested resource (server disk or volume).




Although not required on a technical level, all of the use cases
described above assume the usage of encrypted volume types and encrypted
ephemeral storage as provided by OpenStack.


Proposed changes


* Glance: Adding a container type for encrypted images that supports
different mechanisms (format, cipher algorithms, secret ID) via a
metadata property. Whether introducing several container types or
outsourcing the mechanism definition into metadata properties may still
be up for discussion, although we do favor the latter.

* Nova: Adding support for decrypting an encrypted image when a servers
ephemeral disk is created. This includes direct decryption streaming for
encrypted disks. Nova should select a suitable mechanism according to
the image container type and metadata. The symmetric key will be
retrieved from the key manager (e.g. Barbican).

* Cinder: Adding support for decrypting an encrypted image when a volume
is created from it. Cinder should select a suitable mechanism according
to the image container type and metadata. The symmetric key will be
retrieved from the key manager (e.g. Barbican).


Are you aware of the existing Cinder support for similar functionality?

When encrypted volumes are uploaded to Glance images from Cinder, 
encryption keys are cloned in Barbican and tied to Glance images as 
metadata.  Then, volumes created from those images can consume the 
Barbican key to

This is definitely the biggest challenge, and I think it is one of
those things that is going to be on case by case basis.

In the case of neutron smartnic support with ironic, the spec is
largely living in ironic-specs, but we are collaborating with neutron
folks. They may have other specs that tie in, but that we don't
necessarily need to be aware of. I also think the prior ironic/neutron
integration work executed that way.  My perception with nova has also
largely been similar with ironic's specs driving some changes in the
nova ironic virt driver because we were evolving ironic, as long as
there is a blueprint or something tracking that piece of work so they
have visibility.  At some point, some spec has to get a green light or
be pushed forward first. Beyond that, it is largely a tracking issue
as long as there is consensus.

There was a repository for cross-project-specs, but it is deprecated:
https://github.com/openstack/openstack-specs

So we are currently writing specs for each involved project, as suggested.
You are right, it would be nice to discuss this topic with people from
all involved projects together.

We actually started with bringing this up in the Glance meeting yesterday.
And of course, we would like to discuss our specs in the project
meetings. :)

2018-09-28 Thread Markus Hentsch
Hello Julia,

we will begin formulating an individual spec for each project accordingly.

Regarding your question: as you already assumed correctly, the code
necessary to handle image decryption is driver specific in our current
design as it is very close to the point where the ephemeral storage disk
is initialized.

Our proposed goal of direct decryption streaming makes it hard to design
this in a generic fashion since we can't simply place the decrypted
image somewhere temporarily in a generic place and then take it as a
base for a driver specific next step, since that'd expose the image data.

Best regards,
Markus

If memory serves, the biggest challenge around that solution was
determining who approves such proposals since they still need
per-project specs for the project-specific details anyway. Perhaps
someone who has recently worked on a feature which required

I suspect the avenue of at least three different specs is likely going
to be the best path forward and likely what will be required for each
project to fully understand how/what/why. From my point of view, I'm
quite interested in this from a Nova point of view because that is the
initial user interaction point for majority of activities. I'm also
wondering if this is virt driver specific, or if it can be applied to
multiple virt drivers in the nova tree, since each virt driver has
varying constraints. So maybe the best path forward is something nova
