A Framework for Analysis of Inter-organizational Factors Affecting on the Security of Information Systems using FAHP Approach

Security of information systems as a new area of information technology is of a great importance in creating confidence and growth in the use of information systems. Although in recent years many researchers and IT experts have focused on the technical aspects of security, but less attention has been paid to its organizational and managerial aspects. To investigate the factors affecting on the creating and maintaining of security of information systems, this study identifies the inter-organizational factors. Then, by designing a questionnaire and using Fuzzy Analytic Hierarchical Process (FAHP) technique, the weights and ranks of factors are calculated. The results show that human factor is the most important inter-organizational factor that influences information systems security. Also, the lack of information about the value and importance of information is identified as the most important sub factor.
