About the Authors
Brian Komar,
B. Comm (Hons), a native of Canada, makes his living as a
Public Key Infrastructure (PKI) consultant, speaker, author, and trainer. Brian
speaks at conferences around the world on network design and security
topics. His consulting practice focuses on PKI design and architecture pro-
jects and on research assignments specializing in interoperability between
different vendors’ security products. In his spare time, Brian enjoys traveling
and biking with his wife Krista and sharing a fine bottle of wine (or more)
with his good friends.
Ronald Beekelaar,
M.Sc., a native of The Netherlands, makes his living as a net-
work security consultant, author, and trainer. Ronald frequently trains network
administrators on network design and enterprise security topics. He writes
articles for several computer magazines, mostly about operating systems and
security issues. Ronald lives in Utrecht, The Netherlands, with his wife Kim.
They enjoy traveling abroad. If they find the time, they often travel to European
cities, especially London, to see a theater show and visit museums.
Joern Wettern, Ph.D.,
a native of Germany, is a network consultant and
trainer. Joern has also developed a range of training materials for a large soft-
ware publisher, and these materials are used to train thousands of network
administrators around the world. He frequently travels to several continents
to speak at computer conferences. Joern is paranoid enough to use an enter-
prise-class firewall to connect his home network. Somehow, he still manages
to enjoy the occasional sunny day and the many rainy ones in Portland,
Oregon, where he lives with his wife Loriann and three cats. In his spare time,
of which there is precious little, Joern and his wife hike up the mountains of
the Columbia Gorge and down the Grand Canyon. You can also find him
attending folk music festivals and dancing like a maniac. Joern’s latest project
is to learn how to herd his cats — without much success thus far.
