Information Security (IS) is one of the biggest concerns for many organizations. This concern has led many to focus a huge effort into studying different IS areas. One of these critical areas is the human aspect, where investigation of employees’ behaviors has emerged as an important topic. In this paper, we conduct a systematic review of all empirical studies published on this topic. The review will highlight the theoretical and methodological development and the dissemination of related empirical studies in academic journals throughout the years. At the end of the review, future research considerations are discussed and shared.
