Course Overview

This course covers aspects and principles of network security. Based on many attacks on common technologies used in communication systems, this course illustrates how things can go wrong and provides basic measures to protect a network from mistakes committed in the past. It covers furthermore the fundamental concepts of security and security problems.

Areas covered in this lecture:

• Physical and Link Layer Security
• Network Layer Security
