Effective belief network for cyber security frameworks

Abstract

Cyber security frameworks direct the implementation of cyber security solutions. Managing the implementation of cyber security frameworks is a difficult task due to many problems. Part of these problems are concealed in the framework interdependent components (variables). Various works identified these variables, but they did not show their relationships. In order to reduce potential threats at an early phase of cyber security implementations, a clear understanding of the relationships between these variables is required. This article proposes a causal cyber security belief network in order to facilitate frameworks execution thus reducing threats. The proposed model was tested on random data as well as data provided by the experts. The resultant belief network shows that cyber security objectives are achievable with theoretical minimum threats.
