Line 1: Line 1:
'''Network forensics''' is the process of capturing information that moves over a [[network]] and trying to make sense of it in some kind of forensics capacity. A [[network forensics appliance]] is a device that automates this process.

== Tips and Tricks ==
+
 
+
* The time between two events triggered by an intruder (as seen in logfiles, for example) can be helpful. If it is very short, you can be pretty sure that the actions were performed by an automated script and not by a human user.
