Research in the late 1980s and early 1990s produced a prototype high assurance multi-level secure windowing system that allowed users to see information of multiple classifications on the same screen, performing cut & paste from low to high windows. This retrospective discusses the motivations for the project, reviews the architecture and implementation of the prototype, discusses developments in the intervening years, and concludes with lessons learned.
