Abstract: “The Department of Defense’s increasing dependence on new technology such as unmanned aerial vehicles has created a need for high-assurance systems that deliver the strongest degree of security and safety. However, there has been a notable lack of systems, commercial or government-sponsored research, and engineering that meet these requirements. The Multiple Independent Levels of Security (MILS) architecture is proposed as a solution to meet the needs for critical information assurance. MILS is a componentized architecture based on a commercial off-the-shelf separation kernel that enforces strict communication and partitioned process execution. MILS supports multiple levels of security communication, security policy composition, and modular design so that critical components are able to be evaluated at the highest levels to ensure secure and safe operation.”
