This second semester course comprises projects, labs and discussions in Applied Secure Information Systems Engineering. Specifically, students build a comprehensive platform for secure computing based on best of breed, Open Source components starting with OpenBSD or a similar one. This platform is then contrasted with Java Security and with the secure computing efforts of Microsoft and its associates. A “Student Hackathon” is conducted to test findings and assumptions. Finally, recommendations are made to support the future security-procurement needs for whole elements of the critical Infrastructure.
