E-Learning is an innovative teaching learning process which has taken hype nowadays. Increasing usages of internet for learning process is very productive. As Wikipedia and other web resources are vividly used in teaching. The e-learning S/Ws, websites and portals are very interactive. Using cloud computing for e-learning is another step forward to innovation. As cloud computing provides Infrastructure as a Service(IaaS), Platform as a Service(PaaS) and Software as a Service (SaaS). Thus, for e-learning ,sites are used as cloud computing e.g. Google App Engine, Yahoo Hadoop ,Webguru and many others. Faculties made their own sites for online tests, online filling forms for training programmes, assignments, tutorials, question banks, presentations, time-tables etc. Instead of having completely own infrastructure , it is rather easy to use Google App Engine, which provides facilities like site creating features, emailing system, calendar, spreadsheets and presentations with accessing u...

Existing educational platforms are highly cost-consuming and inefficient in-terms of scalability, flexibility of infrastructures, availability, recovery, accessibility and security. Cloud computing is considered as a flexible business and technological model for providing an Efficient Educational Platform (EEP) due to its significant features. However, an EEP is not a complete solution required by Educational Organizations (EOs), they require Efficient as well as Secure Educational Platform (ESEP). Since cloud computing is an open access global technology, there are several security threats that might take place from malicious users. EOs are reluctant to trust and adopt this paradigm because of threats that can compromise the security of their confidential data. In this research paper, we describe the ICT related challenges faced by educational platforms and we emphasize the significance of cloud computing in enabling an EEP, finally we propose a conceptual model for developing an ESEP. Our contribution consists of several security tools and techniques such as Trusted Virtual Domains (TVDs), Security as a Service (SECaaS), Intrusion Detection Tools, Trusted Platform Module (TPM), virtual TPM (vTPM).

The key management schemes combined with access control technique is discussed for secure content sharing and to protect the e-learning environment. The traditional e-learning mechanism is compared with the cloud e-learning for the better understanding of the cloud usage and advantages. Findings indicate that cloud-based e-learning utilizes cloud services in a secure way and also more flexible and scalable in accessing the e-learning content. KEYWORDS cloud computing, e-learning, key management, secured access control 1 INTRODUCTION Nowadays, many educational institutions encourage the development of cloud e-learning system, which provides access to learning resources at anytime. The e-learning system, which provides more benefits 1 for the e-learners, has been implemented in several universities in different countries. One of the issues identified in implementing the e-learning mechanism is the cost factor 2 for the initial setup. The infrastructure needed for e-learning process implementation is the major problem for several institutions as the budget needed is more to support and update the e-learning system. The other major difficulties in e-learning implementation are obtaining or locating the servers, storage along with the network 3 needed to support, and also the resources mainly the humans needed to maintain and update e-learning system. E-learning process involves internet technology and its similar to the tradition teaching or education methodology. 1 The main process involved in e-learning is the client-server mechanism and also the web-based concepts. 4 Accessibility and Storage are the other major problems in e-learning. Other works 4-6 solved the previous issues faced in e-learning by using the concept of web services and focussed on selection and combination process of learning objects. 7 Cloud computing 8 is the new paradigm in the IT world, which can also help the education sector. Cloud computing and its services can be utilized through the internet. One of the main characteristic feature of cloud computing is scalability, which increases performance. The infrastructure setup needed for e-learning implementation can be provided by cloud computing, thereby reducing the cost and the other resources needed in the establishment of e-learning systems. 9 Trust and Delegations plays a vital role in distribution of content securely. 2,10 The delegation can be carried out in between users and machines in different

Learning has transposed the perception of teaching and learning considering knowledge delivery and knowledge acquirement. Today, e-learning participants access and upload their materials at any time and at any place since elearning technologies are typically hosted on the cloud. Cloud computing has embellished the base platform for the future of elearning, however, security and privacy remains a major concern. Cloud-hosted e-learning technologies as they are accessed over the internet suffer from the same risks to information security aspects namely availability, confidentiality, and integrity. In such a context, data authenticity, privacy, access rights and digital footprints are vulnerable in the cloud. Research in this domain focuses on specific components of cloud and elearning without covering a holistic view of applied cryptographic techniques and practical implementation. Hence, aiming at the various security aspects and impacts of cloud-based e-learning technologies, this paper puts forward reviewing the various cryptographic techniques used to secure data across the whole end-to-end cloud-based e-learning service spectrum using systematic review and exploratory method. The results obtained define several sets of criteria to evaluate the requirements of cryptographic techniques and propose an implementation framework across an end-to-end cloud-based e-learning architecture using multi-agent software.

Cyberspace refers to the boundless space known as the Internet. Cyber security is the body of rules put in place for the protection of this cyberspace. The increasing use of e-Learning systems has been documented by numerous studies and shows continuing growth; little attention has been given to the issue of security of e-Learning systems both in research and education. In this paper, we illustrate an approach to understanding, evaluating, monitoring, measuring and managing cyber security as it relates to e-Learning systems. Security of e-Learning systems represents a unique challenge as numerous systems are accessed and managed via the Internet by thousands of users over hundreds of networks. Moreover, this paper reveals the prevalence of internal cyber-attack as well as a lack of proper IT policies and procedures in e-Learning systems, in light of their standard architecture and their specific security requirements. Also, we discuss the most important security challenges that can be relevant for distributed e-Learning systems. Because e-Learning systems are open, distributed and interconnected, then security becomes an important challenge in order to ensure that interested, and authorised, actors only have access to the right information at the appropriate time.

Many new developments are often plagued with security concerns. Although emerging innovations have all the potential to change systems and people's lives, security issues hinder them adoption and usage. The transformations of data management brought by cloud technologies have helped both individuals and companies. While the cloud allows data storage, connectivity, and recovery stability, it is not immune to the security threats that other new technologies pose. Concerns have been presented over the protection and privacy of cloud users' data. Data leakage, data manipulation, condemnation, a Lack of Services assault, impersonating personalities, also unauthorised access to data are all examples of activities which can appear while data is outsourced to a cloud. Individuals and organisations will orchestrate these attacks, which will jeopardise the reliability and security of cloud networks. The vast majority of colleges and universities are digitising their records, which are then stored in the cloud and handled by a third party. Despite the sacred importance of educational information, the study explores the impact of cloud security problems on schooling. According to the findings, security is crucial for the secure migration and application of cloud technology in the educational sector. It also shows that the growing security threats associated with cloud technology can prevent many education institutions from using cloud services.

According to , security risk management allows the determination of the worthiest attack and the ignored one, it is one way to focus on the serious attacks to better manage the budget and find the best way to use it. Hence, we need to focus on the risks rather than on the threats. To do so, we need to measure the risk and to quantify it. Because sometimes we cannot exclude the risks, our purpose is then to reduce it to a manageable level. Then, security risk management is fundamental in every organization , in fact, a threat determines the risk, and for each risk we can determine the countermeasures.

Security is an important issue in the actual educational context where e-learning increases in popularity and increasingly more people are taking online courses. The e-learning platforms are today production systems that need to be secured. To achieve a good level of security, there are many important elements that must be taken into account: authentication, access control, data integrity, content protection, etc. Information security can be obtained using methods such as cryptography and network protocols. In this paper we will highlight some key security issues that must be taken into consideration in developing and using an e-learning platform. We will also examine some security aspects of one of the most popular open-source e-learning systems: Moodle.
