Hopefully some more knowledgeable here can assist me... My setup: I use a live Ubuntu distro that I boot via USB. I have two external drives I use with this system, one is an external SSD drive, the other is a 2.5 inch 500gb USB external. Both of these external drives have been fully encrypted using truecrypt, and incorporate hidden containers. I'm looking for holes, basically. The linux system uses the ram, and I open the external drives using that distro. Of course, I always unmount the encrypted drives before powering linux down. A. Any security issues re: the linux distro being on a USB drive? The OS itself is not persistent, but are there issues with boot flash drives and data fragments/retention? B. The ext drives - as the entirety of the drive is encrypted, I'd assume that includes all fragments, etc. Any issues I should be aware of? If someone grabs the drive after accessing it a lot using the live linux distro, what are the forensic downsides (if any). If there are specific issues with the SSD vs 2.5 external drive approach, I'd appreciate any information you can give me. I'm familiar with privacy issues as they relate to Windows and normal HDDs. SSD/Flash is new to me from that perspective, particularly when adding in the encryption and access from live linux. I've also used live cd's in the past, but USB is pretty handy, particularly with netbooks, and I'm not sure if that creates security issues in terms of writes to the USB drive while using the linux distro. I'm trying to establish a best practices system with my setup. In my old roadwarrior setup, I kept to windows and vms, and scrubbed drives using Wipe and Clean or the like, along with various and sundry. I don't really know what (if any) actions need to be taken with my setup. Apologies for the shotgun post/requests, and thanks in advance for any help given.
