Common sense tells most of us not to do functions like online banking when on a wireless system while travelling. A research team at Microsoft has uncovered a set of unexpected reasons to support this caution. They determined that most browsers have flaws in their communications protocols when connected through a proxy, such as happens when a wireless network is being used. Their conclusion is that significant improvements are needed in browser connections. This finding has serious implications for system security and for corporate security policy, especially for travelling road warriors.
