I think there's a high level of vulnerability, especially if you travel to foreign countries, because they probably know you are coming and somehow they will be watching you or observing who is out there and will follow you through the process. This is where your choice of technologies and what you use when you're travelling is so critical. As an example, if you are bringing confidential documents, secret documents, on your laptop, you are very vulnerable if you lose that laptop, if you have not secured the documents, encrypted the documents, encoded the documents, waterproofed the documents: there are so many things you can do to secure a document. At the same time, I will not bring secret documents while I'm travelling. I will find other ways to move these documents around.
