Here you can find everything that I have
done in the field of computer science.
There are some papers and slides as well as my
scientific highlights: My bachelor thesis and
my master thesis.
Three dimensional computer graphics have always been
one of my special interests. So I chose to specialize in
this field during my studies. The main product of this
work is my bachelor thesis (in German only, sorry).
The translation of the title is object oriented
modeling of threedimensional scenes and their
conversion into display lists. This work is
concerned with some methods on how threedimensional
scenes can be described in a human understandable,
easy way and how to convert this description in
something, that can be displayed by modern 3d hardware
very fast and efficient.
I worked for 2 and a half years in the
DFN Firewall Laboratory. Among others we created
a filtering proxy named httpf which
webpages (and cookies and stuff like this).
Under the link above you can find the sources and
some documents describing the program and our work.
The proxy was presented on the 7th workshop on
network security, arranged by the DFN-CERT in March 2000 in Hamburg.
In the field of computer security I
did a quite broad overview over the general security
flaws of computers and networks. You can get according article (in German only, sorry),
it was also published in the report 224 (Dep. of
Informatics, University of Hamburg).
To bring my studies to a happy end I did my
master thesis. The titel is
Security services in the TCP/IP
protocol stack, nice 123 (German)
pages for your reading, some deep knowledge
about internet protocols and the mechanisms
to make them safe.
Since the end of my studies I work in the field
of network security especially in the area of
intrusion detection systems. My favourite tools
are Prelude, a complete
hybrid, distributed IDS, and Argus,
a network monitoring daemon. Both were used in the
project eCSIRT.net to gather statistical
data. My actual works can be found on Intrusion-Lab.
Encouraging, praising & criticizing eMails are highly appreciated.
