Abstract

In this study, the authors propose a model describing information sharing and information security measures in an organization using a memory channel communication network (CN). First, the authors highlight communication between the inner members of an organization and communication between inner and outer members, realizing a model describing intra-organizational information sharing and external information leakage. Utilizing this model, the authors determine the percentage of advanced information allocated to inner members most efficient for the organization from the viewpoint of information sharing and information security measures. Then, the allocation percentage is determined considering the structure of the CN and the characteristics of its members. The authors use simple numerical examples in order to confirm whether the model in this study truly represents communication in a real organization. The results confirm that the model is reality-based.
