Abstract
The purpose of this paper is to determine the aspects of the information security management system (ISMS) on which decision-makers must act to achieve the performance targets. Information assets as core of any Information systems (IS) should be taken seriously by a custom security. In this research, we conduct a case study specially using the Delone and McLean’s IS success model. The hypotheses were tested by PLS-SEM of theSmartPLS software using survey data collected among 136 IS and IT professionals. We found that the ISMS (system, service and information qualities, maturity level of information security risk management process) and performance are directly related on one hand, and indirectly by the IT capabilities of the company in the other hand. This shows that mastering security information management risks process is crucial for an enterprise because it greatly contributes to organizational performance, improve the IS’ support such as IT management, IT personal skills and IT infrastructure. This work has explored the feasibility of using the IS success model on ISMS, a key world know element, where Africa is both the target of the informational mobility, hackers and especially in the global economy. We consider the IS success model with 4 dependent variables including maturity level of process.

According to the mediation effect analysis process proposed by Nitzl et al, we note that the direct and indirect effect between the information security management system (ISMS) and PERFORMANCE are significant because the value of the t-statistic for each link is greater than 1.96 by Hair et al, This means that the IT CAPABILITY has a partial significant mediation effect between ISMS and PERFORMANCE
Summary
The adoption of information technology (IT) has become a necessity for all organizations.
