The article assesses the level of navigation safety, in theoretical terms, defines the complexity of managing navigational risks in practice. The issues of assessing the navigational safety have been studied due to the importance and relevance of the issue in question, however, due to the great complexity of the problem under consideration, the article considers and indicates the directions for the development of the solution of the given direction, where, first of all, it became necessary to analyze the issue of assessing the levels of navigation risks when navigating vessels of various types in difficult navigation conditions.

Small and Medium Enterprises (SMEs) are increasingly using ERP systems to connect and manage all their functions, whether internally between the different departments, or externally with customers in electronic commerce. However, the selection of the right ERP system is usually an issue, due to the complexities of identifying the criteria, weighting them, and selecting the best system and provider. Because cost is usually important for SMEs, ERP systems based on Cloud Software as a Service (SaaS) has been adopted by many SMEs. However, SMEs face an issue of selecting the right system. Therefore, this paper proposes a fuzziness ranking engine system in order to match the SMEs requirements with the most suitable service provider. The extensive experimental result shows that our approach has better result compared with traditional approaches.

To have a complete and comprehensive understanding of the research subject and to form an integrated legal framework for it, I have sought comprehensively to cover the major written literature on the issue under consideration. I also benefitted from a wide range of research and academic studies pertaining to the same topic, although that literature did not specifically address the issue of consumer rights in electronic contracting in the Saudi e-commerce system. Rather, it addressed only the civil and criminal protection of the consumer in e-commerce. I have divided the reviewed literature into two sections according to the sources.

In a previous study we proceeded to the remodularization architecture based on classes and packages using the Formal Concept Analysis (FCA)[13] [14] [30]. we then got two possible remodularized architectures and we explored the issue of redistributing classes of a package to other packages, we used an approach based on Oriented Graph to determine the packages that receive the redistributed classes and we evaluated the quality of a remodularized software architecture by metrics [31] [28] [29]. In this paper, we will address the issue of the efficiency of the Oriented Graph in the remodularization of software architectures compared to the Formal Concept Analysis FCA method. The formal method of FCA concept is not popularized among scientists as opposed to the use of the labeled directed graph. It is for this reason that our directed graph approach is more effective in its simplicity and popularity.

As various measures of law observance obligations such as mandatory obligation of privacy impact assessment (PIA) for public institutions and authorization of information security management system (ISMS) are put into practice, increase in demand for information security consulting and securement of information security consultants are emerging as a major issue. The purpose of this study is to empirically investigate what core competencies information security consultants should possess and how much they actually possess them. By analyzing the differences in perception between practitioners and managers on core competencies, this study understands difference of views between the two groups and suggests ideas for cultivation of information security consultants.

The most significant change and trend in the information security market in the year of 2014 is in relation to the issue and incidents of personal information security, which leads the area of information security to a new phase. With the year of 2011 as the turning point, the security technology advanced based on the policies and conditions that combine personal information and information security in the same category. Such technical changes in information security involve various types of information, rapidly changing security policies in response to emerging illegal techniques, and embracing consistent changes in the network configuration accordingly. This study presents the result of standardization and quantification of external access inference by utilizing the measurements to fathom the access authorization performance in advance for information security in specialized networks designed to carry out certain tasks for a group of clients in the easiest and most simple manner. The findings will provide the realistic data available with the access authorization inference modes to control illegal access to the edge of a client network.

With response to the critical issue of global warming, Smart Grid system has been extensively investigated as next efficient power grid system. Domestically, Korean is trying to expand the usage of Electric Vehicles (EVs) and the charging infrastructure in order to replace the current transportation using fossil fuels holding 20% of overall CO2 emission. The EVs charging infrastructures are combined with IT technologies to build intelligent environments but have considerable number of cyber security issues because of its inherent nature of the technologies. This work not only provides logical architecture of EV charging infrastructures with security threats based on them but also analyses security requirements against security threats in order to overcome the adversarial activities to Smart Grid.

In order to develop smart grid communications infrastructure, a high level of interconnectivity and reliability among its nodes is required. Sensors, advanced metering devices, electrical appliances, and monitoring devices, just to mention a few, will be highly interconnected allowing for the seamless flow of data. Reliability and security in this flow of data between nodes is crucial due to the low latency and cyber-attacks resilience requirements of the Smart Grid. In particular, Artificial Intelligence techniques such as Fuzzy Logic, Bayesian Inference, Neural Networks, and other methods can be employed to enhance the security gaps in conventional IDSs. A distributed FPGA-based network with adaptive and cooperative capabilities can be used to study several security and communication aspects of the smart grid infrastructure both from the attackers and defensive point of view. In this paper, the vital issue of security in the smart grid is discussed, along with a possible approach to achieve this by employing FPGA based Radial Basis Function (RBF) network intrusion.
