5. SUMMARY AND CONCLUSIONSOSA syste

5. SUMMARY AND CONCLUSIONSOSA systems have a large amount of appeal because of their potential to lower program costs, increase access to COTS, and ease integration. OSA programs also enable interconnectivity. With the greater connectivity comes the potential for more vulnerability as it may provide greater access for cyber intruders.This accessibility has prompted concerns that OSA systems are more vulnerable to attack. More research is needed to demonstrate how open systems can facilitate more secure systems through the use of strict interface definition and control. Currently, FACE has a lot of momentum in the Airborne Systems communities especially within the Navy and Army. There have been a number of demonstrations of FACE presented at FACE Technical Interchange Meeting (TIM) in January 2016 [].OMS is in use in the Air Force and Unmanned Air UCI/STANAG 4586 has focused on the definition of the interface and message set between control stations and unmanned air vehicles. Blue Guardian has developed a platform architecture using the Air Force's OMS reference architecture and conducted a ground and flight test program of multiple payload combinations [10].There is more opportunity to expand the use of OSA standards such as FACE and OMS for sensors system and subsystems, weapon systems, and network platform interfaces. There is a need for more development of the safety critical and high integrity aspects of these standards as well.There is significant opportunity for better tool support for component integration and analysis as well as transitioning the use of the OSA standards into industry.
