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.
The following list of publications covers only those, which are or were published during participation at the Graduiertenkolleg / PhD program.
