Lectures.

Sometimes I present lectures, in general the topic is related to Free and Open Source Software combined with security. That seems to be a subject I've a special interest for. Perhaps very disappointing for most of you, but these lectures are always held in Dutch, being the only language I master adequately.

These lectures are presented at both congresses with public access as privately held gatherings of organizations. Some examples in the former category are :

• NLUUG autumn conference 1999:Abstract Fred Mobach: Firewalling with Free Software
• Linux2000 - Programm October 10, 2000: Internet security and Free Software
• Linux Expo Amsterdam 2001: Linux and Internet Security
• Linux 2001: Are we willing to secure the stuff, and at which costs ?
• NE2000 - Activities - Workshops: secure workstation
