—Be aware of the risk, once in-country, of connecting to public networks. Wireless networks in hotels and coffee shops, for instance, are often compromised and malicious codes can be downloaded into your machine, Ghosh said. Even if you leave home with a clean laptop and it's wiped clean after the trip, someone can still capture what you're typing in emails or your credentials when you're entering them during the trip. Not much can be done about that — it's just a risk you have to be aware of so you are careful to avoid activities such as logging into your bank to do financial transactions, he said.
—Travel aside, your company should also routinely take steps to limit the types of applications that can run on their systems, regularly update computer programs, and tightly control the number of people who have broad access privileges to the company networks, said Alan Paller, director of research at SANS Institute, a computer-security organization.
