As information travels across the wire it is logged by everything in between to keep track of what is happening. Information travels networks faster than we can blink. Also it may surprise you that clearing your history in your browsers does not delete your network traffic... we know what you did.. that is gross by the way.
Besides that we will still love for you to come to our next CSG meeting which we will be talking about Network forensics. Join us in ECSS 2.203 on September 25th at 7 PM to learn how to make sense of the crazy traffic that travels on the wire through the network.
