Event description

Description

Aims and Objectives

The protection of communication networks against new and unexpected attacks remains a challenging task. Attacks become more sophisticated and new vulnerabilities emerge every day. Proactive solutions often fail if new attack strategies are used or undetected vulnerabilities are exploited. Network supervision methods are essential to establish situational awareness in communication networks. They help to detect anomalies in communication patterns and provide the first step for the detection of new attack types.

Network measurements and traffic analysis are important tools for network security. In addition, they support network operation and provide the basis for answering a wide variety of research questions about network structures, QoS parameters, user behavior, protocol performance and other characteristics of communication networks and protocols. Knowledge about such methods is therefore not only valuable for researchers in network security, but also useful for students working in different areas in the field of communication networks. The introduced statistical data analysis and machine learning methodologies can be also applicable to other fields.

This class focuses on network measurement and network traffic analysis methods for network security. Students learn about network measurement standards, statistical network traffic analysis and anomaly detection methods. They learn how malware uses communication networks to spread and how communication can be hidden in common protocols by using network steganography. In practical exercises, students learn penetration test, network data exploration and anomaly detection methods. They learn how to analyse IP darkspace traffic and how to detect covert channels in TCP/IP traffic.
