Where we stand in multilevel security (MLS): requirements, approaches, issues, and lessons learned

Many government planners and trusted system vendors have an oversimplified view of actual user needs for multilevel security (MLS).

This paper is primarily derived from work performed under Contract DAAB07-94-C-H601 for the Defense Information Systems Agency (DISA).<
