What's difference between partially and full encryption algorithm on EEPC 5.2.4?

Jump to solution

Hi..

     I read from document about that but not clear. My customer ask me in deep technical. I test by bring full and partially encrypted hard disk boot by WinPE. I can't see the data in both harddisk.

     Could you please tell me what difference??

Thank you.

partial only encrypts the first 10% of the drive - it's for TESTING ONLY. Yes, if you loose the machine, 90% of the drive will be unprotected.

Hi,

Full Encryption : will encrypt whole drive which should be used in live environment

Partial Encyption : will only encrypt first 10% of drive. and it is used for test environment. when you do not want waste (wait) time for encryption/decryption. For example you want to show POC of Recovery to customer.

You mean that benefit of partial for only POC?

When deploy to client can I use parital encryption to reduce the time or recomment to use full?

So If I used partial, and my laptop is lost. Can stranger read data or recovery harrdisk?

My customer want to know the benefit.

..

Thank you for your all comments.

correct me if i;m wrong..

example in 40 gb drive you may only used 10gb space.

Full Encryption - encrypt the whole disk which is 40gb which including the unused space or sector.

Partial encryption - only encrypt 10gb which being used by data.


There is pro and cons..

cons for full - more time to decryt, bigger space to image

pro for full not easy to identify which sector being used for data..

Not to get too off track, but data isn't stored in a linear form on a disk.  That means that even if you're only using 10GB of data, it's spread across the entire disk over time.  While I'm not certain, I'll bet that McAfee encrypts disks from the first encryptable sector on in a linear fashion.  This means that unless your data all resides in the first 10 GB of that 40 GB disk (by sector number), which is rather unlikely, you're not encrypting all of your data with a partial encrypt even if you're using 10% or less of the available space.

If someone didn't want the entire disk encrypted, you'd want to opt for File based encryption instead of Full Disk Encryption.
