Cyber Security Measurement in Depth for E-learning Systems

Abstract

As the reach of the internet expands to cover ever broader aspects of our economic and social welfare, cyber security is emerging as a major concern for researchers and practitioners, dealing as it does with privacy, confidentiality, user authentication, etc. E-learning systems epitomize computing systems and networks of the internet generation, since they involve multiple stakeholders, geographically distributed resources and data, and special requirements for confidentiality, authentication, and privacy. In this paper, we illustrate a rigorous cyber security measure of dependability to quantify security threats which is the Mean Failure Cost for E-learning systems. The proposed infrastructure, allows an analyst to estimate the security of a system in terms of the loss that each stakeholder stands to sustain as a result of security breakdowns. In addition, we have extended its formula to measure the critical security requirements. Our focus is to offer a diagnostic of possible problems of the non secure systems and a depth insight interpretation about critical requirements, critical threats and critical components regarding the cyber system. This extension is beneficial and opens a wide range of possibilities for further economics based analysis. The theoretical aspects, the practical case study and the deep of interpretation developed in this paper offer strengths guidelines in the science of cyber security in our modern society.
