A MULTI-CRITERIA EVALUATION OF INFORMATION SECURITY CONTROLS USING BOOLEAN FEATURES

For organizations, the protection of information is of utmost importance. Throughout the years, organizations have experienced numerous system losses which have had a direct impact on their most valuable asset, information. Organizations must therefore find ways to make sure that the appropriate and most effective information security controls are implemented in order to protect their critical or most sensitive classified information. Existing information security control selection methods have been employed in the past, including risk analysis and management, baseline manuals, or random approaches. However, these methods do not take into consideration organization specific constraints such as costs of implementation, scheduling, and availability of resources when determining the best set of controls. In addition, these existing methods may not ensure the inclusion of required/necessary controls or the exclusion of unnecessary controls. This paper proposes a novel approach for evaluating information security controls to help decision-makers select the most effective ones in resource-constrained environments. The proposed approach uses Desirability Functions to quantify the desirability of each information security control taking into account benefits and penalties (restrictions) associated with implementing the control. This provides Management with a measurement that is representative of the overall quality of each information security control based on organizational goals. Through a case study, the approach is proven successful in providing a way for measuring the quality of information security controls (based on multiple application-specific criteria) for specific organizations
