Firmin,

 

We are using encrypted drives on our laptops.  They are the Seagate Momentus
5400 FDE.2 drives that have hardware-based encryption.  We are pretty much a
Dell shop, and you can get the drives as an option on some of the newer
Latitude D-series and I think on the new E series as well.  We retrofitted
all the laptops that were compatible for just under $100 per drive (120GB).
7200rpm drives are coming this fall as I understand it.

 

You can also get an enterprise version that lets you do all the management,
key generation, key storage, and key recovery from a central server (MS-SQL
Server 2005 and IIS6 required).  For us to get a 25-user license for the
server software, plus maintenance per seat, plus the drives, was under
$3000.

 

Because all the encryption/decryption is done on the drive itself in
hardware, there isn't the performance hit you get with software solutions,
and because you have central management of your keys, it really isn't a big
headache to manage.  I'm still getting it all figured out, but you're
welcome to come over and see it in action if you like.  We are also
considering a policy that bans unauthorized CD's, DVD's, thumb drives, and
other removable media from our computers.  That is still in discussion with
the executive management of our department, however!

 

Eddie Parker is also deploying a messaging security gateway from Proofpoint,
which is sort of like a Barracuda that does encryption.  As I understand it,
this device will detect sensitive data and ask the user to encrypt it before
it will send out the message (if they don't encrypt it first like they're
supposed to!)  Eddie is very happy with it, and it is up and running in our
office now.  We just have to do some user training on it to be fully
operational.

 

Fundamentally, encrypting your storage hardware gives you protection against
the physical device being stolen - that is why you see it (software or
hardware based) on laptops - they are the most at risk for being stolen.  If
a server (or even a desktop) is compromised, you don't get the benefit of
the encryption because the intruder is reading data off the disk based on
the credentials they have compromised or the elevated privileges they have
gotten.  I suppose you could have designated encrypted areas on a disk that
you would have to authenticate to somehow, but that would begin to be a
management nightmare on a couple of levels.  I know that we got pinged on an
audit for not having encryption on our servers when one of them got
compromised a couple of years ago, and both Jim Smith and Phil Burnett were
not to keen on putting encryption on servers, and I can understand why.  We
still don't have it on our servers.

 

VPN's are the obvious solution for encryption over-the-wire, but that brings
in its share of headaches too!

Subject: [MSUNAG] Encryption on File servers, desktops and laptops

 

Encryption is something that I have been thinking about for a while now and
a lot of the solutions that I have seen are extremely user unfriendly, very
costly,  and sometimes has little management features OR if you look at free
solutions there is usually no management of keys which could be tricky when
keys are lost or passwords are forgotten. 

 

Protecting data through encryption is a great way to go, we all can agree
there but as that data moves from servers to laptops and/ or to other mobile
devices, it can become exposed.  

 

Is anyone encrypting their file servers? If so what are you using?

What about email? Not only on the servers but what about on the desktops?

Is anyone encrypting their laptops' hard drives?
