01731, Network Steganography / Network Information Hiding, Chapter 7a Network-level Countermeasures)

This is a video of the class 01731 (FernUniversität in Hagen) and additionally part of a whole online class on network information hiding by Prof. Dr. Steffen Wendzel. Slides, exercises and reading assignments: https://github.com/cdpxe/Network-Covert-Channels-A-University-level-Course/blob/master/README.md This session introduces basic network-level countermeasures in an exemplary manner. First, I show traffic normalization, followed by three detection approaches for selected timing channels (inter-packet times pattern). Finally, I introduce and exemplify the concept of countermeasure variation. Please note that fundamental countermeasures that are *not* specific for networks were already introduced in chapter 3. Hiding patterns, including the inter-packet times pattern, were introduced in chapter 5.
