I'm new to taking security measures to ensure the safety of my data and my work on my computer. I'm a student in college and I study a lot at Starbucks and in school libraries where there is public wifi. Just from reading some of the posts I know i should be doing more in terms of security but I"m not sure what to do and where to start. How do i stay safe from using bittorrent or uTorrent over a public wifi? Believe it or not I'm not torrenting music or movies but mostly PDF's of books and documents that I need for research and references that are either 1) extremely hard to find and out of print 2) unavailable for purchase from Amazon. I'm using a Macbook Pro. What steps do I need to take and what programs do I need to install for OS X? I read that MADMAC is a good program but that's for Windows based computers. Also should I be using Tor? I have a mac computer.
