project description

Visual Analysis of Network Communication

Phd Thesis Florian Mansmann 2004
University of Konstanz
Graduiertenkolleg funded by Deutsche Forschungsgemeinschaft (dfg)

Network communication has become indispensable in education, government, and business. Along with the pervasive use of the internet, the problems of information overload as well as large-scale misuse of the network communication infrastructure arise. Especially misuse for destructive purposes, such as spreading malicious code, compromising remote hosts, or damaging data through unauthorized access, has grown immensely in recent years. In this talk, I will exemplify these two problems and show how visualization technology can help to solve them.

In the context of personal information management, I research novel visual approaches to interact with large collections of emails, namely the space-filling geographical distortion technique HistoMap, a calendar-based recursive pattern to show temporal distributions, and a self-organizing map to retrieve similar emails. In the context of network security, it is promising to complement automatic intrusion detection mechanisms through visual analysis methods because novel attacks are hard to identify with automatic methods and pure statistics about the number of alerts rarely lead to the essential insight. To gain insight into the distribution of diverse traffic loads and large quantities of security alerts over the internet, I will introduce the Hierarchical Network Map, which is designed as a spatial, hierarchical, and space-filling visualization technique of the IPv4 address space. Different visual approaches to analyze application port as well as host statistics will be discussed.
