List, I am conducting some research on threats to WAN traffic in the USA and would appreciate your input in 2 areas: 1) Do you have any anecdotes you can share with me that substantiate the threat posed by persons seeking to wiretap private high-speed data circuits? Any documented stories about spies wiretapping or insiders at the telcos abusing their privileges? 2) What methods have you seen used to mitigate the risk posed by sensitive data in transit across public circuits, and where have you seen this? With regards to #2, please be as specific as you can. For example, some companies utilize bulk encryption to secure leased circuits in addition to encryption at various other layers such as session and application. I know of other ways to mitigate the risk, and so I'm curious what you have seen. I specifically excluded foreign network links based on the assumption that foreign intelligence services often have unfettered access to local telecommunications providers in their respective spheres of influence. Feel free to reply to me directly if you are not comfortable sharing with the entire list. Thanks, Greg
