Technique for assessing the risk of threat materializing when processing data in automated systems of organization

The paper considers issues related to the assessment of risks to information security arising in automated systems that process Organization’s information assets. There is proposed a step-by-step mathematical model presented as ‘Technique for assessing the risk of threat materializing when processing data in automated systems of Organization’. The developed technique allows one to estimate the extent of risks that result in materializing of threats to Organization’s information assets when those are being processed in automated systems. The main problem solved with the help of this technique is determination of the numerical value for the information security risk, which is done in order to take measures to protect information assets.
