I used to keep all my sensitive details and documents in my home directory, and with a login password and Filevault enabled, I thought all my stuff was safe, secure and inaccessable to anyone who wanted to get at them. To my shock horror, I have recently found out that people can easily access any part of my system by using a FireWire cable and something called Target Disk Mode. Is there anything I can do to make my document more safe? Preferable I want to put all my sensitive stuff in a folder and encript it, so that no one can have access to the folder without a password. I've read about Disk Images, but I can seem to get my head around them. As when I try to create them I have to specify a size. My questions are: 1. Can I create a Disk Image with size restraints? (So it can grow or shrink depending on what I put inside). 2 If I use a very secure password, will my documents be safe in a Disk Image? Or is there a way around that as well? Thank you in advan for any help.
