This book constitutes the refereed proceedings of the 9th International Conference on Formal Engineering Methods, ICFEM 2007, held in Boca Raton, Florida, USA, November 14-15, 2007. The 19 revised full papers together with 2 invited talks presented were carefully reviewed and selected from 38 submissions. The papers address all current issues in formal methods and their applications in software engineering. They are organized in topical sections on security and knowledge, embedded systems, testing, automated analysis, hardware and concurrency.
