    Interesting little Problem to solve.... ( Enterprise Level USB Encryption )

    I've been asked to look at some ideas for the use of USB sticks in our Environment to allow some quasi - romaing abilities for users without laptops.

    The first solution that saprings to mind is a USB stick , especially due to cost / conveniance factors.

    Its not that easy however ( it never is ). I'd like the sticks to only work when connected to our network ( 2500+ machines , W2k single Domain AD ) I'd also like data to be only accessable by the user and admins.I dont want anything other than "approved" devices to connect either.Just to make it eaven more fun , this might get issued to a fair few number of users so some form of centralised management would have to be possible.

    I've had a quick look at some of the 3rd party USB encryption products , but none seem to be designed to prevent insertion into an untrusted machine.

    My other first thought woudl be to use the full extent of NTFS encyption - we have a number of CA's installed in the domain so that you'd need to contact one of them prior to being able to decrpt , which woudl solve the first and secoind issues , but wouldn't prevent untrusted sticks being used.

    I suppose that could be combined with a 3rd party USB management tool , which I think creates an MD5 hash for each stick , and hance a liust of trusted devices ?

    any ideas folks. If you want more detail , ask , if its not too confidential , then I'll post it here.

    while I'm pondering your question as a whole, you may want to consider the fact that USB sticks, compared to disks tend to have a shorter lifespan.
    It is Inevitable.....

    They do ? I'd always figured that as solid state devices they'd be ok in terms of reliability.

    What disks would you be comparing them with ? microdrive type devices ?
