Encrypted Mac USB

    A client mentioned to me that she was keeping confidential information on a thumb drive that she's been carrying around between her home and office.  When I asked about the type of the confidential data, I followed that question by asking -- if the drive were lost, would that cause a significant problem.  Of course knowing the answer, I then suggested encrypting the thumb drive. 

    This will be a two part post, probably with a separate title -- one for Mac and the other for PC. 

    Starting with Mac, we pull up the Disk Utility tool:



    We highlight the volume we'd like to protect, choose Erase, and we select Mac OS Extended (Journaled, Encrypted):


    We choose a password and verify:


    Next, we're going to choose Security Options:


    We're going to slide the needle over from Fastest to the first position to make it a little more difficult to compromise in the event the drive is lost:


    And finally, we're going to start the process by choosing Erase:


    This will take some time...


    When the process is complete:


    We can now eject the volume.  When we insert it back into the machine, we get prompted for our password:


    This setup will ONLY work with the Mac platform.  In other words, if you insert this into a PC, you will not be able to do anything with it.  Most people I know who use Mac at home are using Mac in the office.
