Suppose I have a live bootable USB drive with Linux installed on it. It is encrypted. I am booting off it on another computer with default OS Windows.
How much separation is there between the host machine and the USB drive while I'm using the Linux OS on the USB drive? Can something be installed on the host machine at a lower level that can still access any personal information or monitor the activities on the USB drive?
(Background: Not trying to do anything shady. Just recently started work at a consulting company with a lot of travelling ahead. I can bring two laptops, but if I can get away with using a portable OS on a USB drive on my work laptop to read personal e-mails and pay bills/do banking without leaking my personal information, it would make my packing much easier. My work explicitly states that they monitor all online and USB transfers using Symantec.)
