Network Security While Traveling?

truesaer writes "I'll be spending all of next year backpacking through South America. In the past I've used Internet cafes while away, but this time I plan to bring a netbook and rely primarily on Wi-Fi hotspots. I'll be facing the same issues and risks that business travelers in hotels and airports face, as well as those encountered by millions of other backpackers, gap-year travelers, and students. Since my trip is so long I'll have no choice but to access my banking, credit card, and investment accounts on public networks. I will not have a system at home to connect through. Other than an effective firewall, a patched system, and the use of SSL, what else should I do to protect my information? Keep in mind that many places have very poor bandwidth and latency."

dm-crypt

All network security is for naught when someone can just steal your netbook and read all the passwords and form data that firefox helpfully remembers for you. You have to make sure that your firefox profile directory (as well as all other confidential data, like passwords and bank statement pdfs) is stored on an encrypted block device. On Linux, a loopback device encrypted with dm-crypt works well.
