Very interesting article. I will have to play with the concept sometime.

EFS is a very interesting technology... perfect for mobile users who might accidently get drunk with a laptop holding military software:

If you've got sensitive data, this is definitely a technology to consider. The public key encryption is RSA and the symmetric is DESX, two established and proven encryption algorithms. The fact that it's seemless to SQL Server (unless we use the wrong account to encrypt) is another big plus.

The link is quite funny. And if true then I bet those guys got a real good duty after that if not court martialed.

Good to know is RSA and DESX as those have well proven.

Excellent article. We are struggling with how to protect personal information. This article is complete enough that I am going to circulate it around our org.

Thanks for taking the time to do a good job on a cool NT feature!!

Very interesting. Course, be sure you protect the backup files as well. Especially when they are on tape.

For laptops, we use Pointsec (www.pointsec.com) here at JD Edwards. Help Desk has a central password reeset if you forget it.

Backups are a particularly troublesome bird. Especially since throwing a password on a backup doesn't encrypt them. Speaking of which, anyone have any experience with SQLLiteSpeed and how it works?

I just got a copy and will be running on my test environment. It does have encrytion. Any thing specific you are curious about as I will be testing for company purchase and I plan to do anything it will let me?

I'd like to see how the times compare between a normal backup and SQLLiteSpeed backup, especially with encryption turned on. I'm going to DL a copy myself and test it out fully. I saw that it works using extended stored procedures, so I've got a good idea how it works, I just want to know how it compares.
