Phillip, if you use B), you don't need A). And how do you want to prevent traffic analysis? In a telekcommunication system, where all actors are privat companies and act for the state institutions and with a star topology, you will never be able to prvent any form of traffic analysis. Your writing is a little bit naive for me. greetings, willi On 13/03/2017 20:13, Phillip Hallam-Baker wrote: > I think this particular failure demonstrates the situation pretty well: > http://www.zdnet.com/article/leaked-us-military-files-exposed/ > > A) Without transport encryption, every network link is a potential point of > compromise via traffic analysis. > > B) Without end-to-end data level encryption, every non endpoint device, > every hard drive or removable storage is a potential point of compromise > > C) Without end point security, the end points are a potential point of > compromise. > > D) Without trustworthy personnel, you are vulnerable to an insider threat. > > The security controls you need depends on your information security assets > and your security concerns. > > If you are a high level security target then you need A + B + C + D.
