Addressing Cybersecurity within e-Learning systems becomes empowered to make online information more secure. Certain competences need to be identified as necessary skills to manage security online such the ability to assess sources and architectural components, understanding the privacy, confidentiality and user authentication. Security management approaches quantifying security threats in e-learning are common with other e-services. It is of our need to adopt a quantitative security risk management process in order to determine the worthiest attack and the ignored one, based on financial business risk measure which is the measure of the mean failure cost.This paper proposes a cyber security measure called the Mean Failure Cost (MFC) suitable for e-Learning systems. It is based on the identification of system’s architecture, the well-defined classes of stakeholders, the list of possible threats and vulnerabilities and the specific security requirements related to e-Learning systems and applications. In the mean time, security requirements are considered as appropriate mechanisms for preventing, detecting and recovering security attacks, for this reason an extension of the MFC measure is presented in order to detect the most critical security requirements. Also this paper highlights the security measures and guidelines for controlling e-Learning security policies regarding the most critical security requirements.

2. Security Challenges In E-Learning Systems

E-learning concept is the use of technology to deliver information for training. This modern education is useful and interesting as it creates interactions between learners and instructors, or learners and learners regardless of time and space (Sun et al., 2008). E-learning is an educational system where the instructor and the learner are at distance, collaborate and communicate using the technology. E-learning is the delivery of a learning, training or education program by electronic means as it involves the use of a computer or electronic device in some way to provide training, educational or learning material (Stockley, 2008). Nowadays, e-learning has become a popular way of learning for schools and businesses, it has increased exponentially in recent years (Sun et al., 2011).

The E-learning has gone through a spectacular development during the past years. In today's Internet age, education requires the share and the distribution of information. We need a system or a platform, and then we call this an e-learning system or distance learning system or the e-learning platform which supports the online and / or the live and / or the blended learning processes. When they support live learning they can be an electronic support for course.
