The NATO Science and Technology Organization (NATO STO) published on its webpage the Technical Report of Human Factors and Medicine (HFM) Panel Research Task Group (RTG), titled Human Systems Integration Approach to Cyber Security (NATO STO HFM-259). 
This RTG-259 was established in 2015 and 7 NATO and Partnership for Peace nations among which Bulgaria, Canada, Germany, the Netherlands, Sweden, Ukraine and USA contributed to the study. 
Bulgaria was the lead nation and the Chair of the RTG was Prof. Dr Sc. Yantsislav Yanakiev from the Bulgarian Defence Institute “Prof. Tsvetan Lazarov” who is also Principal National representative in the Panel Human Factors and Medicine. 
The main goal of the RTG was to promote cooperative human-centred research activities in a NATO framework on the complex phenomenon of cyber security as a socio-technical system. The idea was to implement a common research perspective to study cyber security that focuses on the interrelatedness between technology and software developments, concepts, strategies and doctrines, organizational processes improvement and human performance. 

The NATO STO HFM-259 team developed and tested a Human Systems Integration framework to study cyber security, knowledge base and used sophisticated software tooling to analyse the role of human factors in cyber security. Part of the products of the work (database and tool) are available to be used by NATO STO and interested national institutions of the contributing nations.
