In this study, the relationship between “human beliefs” and “absorbing specialized knowledge” necessary to create cyber security has been investigated. The framework of this research is based on the knowledge-based perspective of the firm and the cost of knowledge exchanges, and its research method is descriptive-survey and it is applied research in terms of purpose. To test the hypotheses, a number of 262 people working in centers for analysis, exchange and sharing of sensitive information about cyber security were prticipated in the study. A questionnaire was used to collect data and the validity of each construct was calculated by calculating the correlation between item-test, item-rest, and average inter-item correlation. The reliability of the questionnaire was determined using Cronbach alpha formula. Factor analysis of the principal component was also performed by oblique rotation. Findings show that “belief in the source”, “belief in the usefulness of knowledge” and “belief in reciprocity” have positive and significant relationships with knowledge absorption, but “belief in reward” has no relationship with “knowledge absorption”. Also, at the end, the effects of research on experts in this field and future research are discussed.
