Thomas Maus holds a graduate in computer science. He is consulting in the areas of system security, the analysis, tuning, and prognosis of system performance, as well as the management of large, heterogenous, mission-critical installations since 1993. Projects range from architecture, implementation and operation of large application clusters over technical project management, organisational and technical trouble-shooting, security assessments, establishing of security governance processes, security policies and analysis for trading rooms and the like to training of international police special forces for combatting cyber-crime. He started his computing career 1979, at the age of sixteen, when winning the computing equipment for his school in a state-wide competition. Soon followed the teamworked development of a comprehensive SW for school administration on behalf of the federal state -- here a long lasting affection for questions of system security, performance and architecture started. Around 1984 he fell in love with UNIX systems and IP stacks and embraced the idea of Free Software.
