As for the relevance of using E-leaning as a kind of modern education for schools and business throughout the world, the support of the newest technological components is important. In contrast, the integrity of this cyber system has become more critical. Security of E-learning systems is a current issue that needs to be highlighted to guarantee educational process with higher quality and to maintain its well running. Nevertheless, considering a total secure system is really a challenge. Security assessment policy and metrics are recommended, they serve as a guideline to the issues related to the availability, reliability, integrity, and confidentiality of the online teaching/learning system. In this paper, we illustrate a rigorous cyber security measure to quantify security threats which is the Mean Failure Cost for E-learning systems and then we propose an extension of its formula to measure the critical security requirements. Our focus is to enrich the MFC measure in order to develop a comprehensive science of cyber security and to get more safe and effective systems.
