Network access control should be able to effectively block security threats to the IT infrastructure, such as unauthorized access of unauthorized users and terminals, and illegal access of employees to internal servers. From this perspective, it is necessary to build metrics based on relevant standards to ensure that security is being met. Therefore, it is necessary to organize the method for security evaluation of NAC according to the related standards. Therefore, this study builds a model that combines the security evaluation part of ISO / IEC 15408 (CC: Common Criteria) and ISO 25000 series to develop security metric of network access control system. For this purpose, we analyzed the quality requirements of the network access control system and developed the convergence evaluation metric for security of the two international standards. It can be applied to standardization of evaluation method for network access control system in the future by constructing evaluation model of security quality level of network access control system.

The flow of time, depending on the company's ongoing business link to guarantee the proportion of much greater importance, it in the organization as part of an enterprise-wide level, rather than acting on the information society has been considered as the topic of race. Information Security Governance, the integrity of the information, service continuity, the three kinds of information asset protection purpose begins. It is essential for corporate governance, transparency should be part, must be aligned with the IT framework. Existing information security governance framework that small businesses a wide range of governance issues and interests have never had. Therefore, we simplified the information security governance framework is proposed, and solve problems, and propose a framework for analysis of the safety and efficiency through the analysis of the effectiveness of the proposed method were discussed.

Recently, the Internet of Things is an important technology with a Cloud computing services and a Big data in the IT fields. and The Internet of Things is widely used in various industries. This trend may be referred to as the emergence of significant based technologies for realizing a ubiquitous times. But the security problems of Internet of things are expected to increase with being realized in a variety of industries. and it will be have to provide a corresponding technology to the security threat for this. Therefore, this paper will be analyzed to the security threats of the Internet of Things by the cases. Thereby this is expected to be utilized as a basis for the countermeasure of Internet of Things in a future.

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.

The International Civil Aviation Organization (ICAO) and the World Customs Organization (WCO) emphasize securing supply chain security through mutual cooperation between aviation security and customs by establishing a standardized security system by regulations, procedures and practices of international air cargo. Accordingly, in accordance with the Aviation Security Act, the known consignors system aims to secure cargo security before loading air cargo into the aircraft, while the customs AEO system is a public-private cooperation program that focuses on simplification of customs clearance procedures. These systems basically have the same purpose of effectively identifying high-risk cargo through a risk-based approach in international air cargo transportation and preventing risks in advance, and the content that a common basic standard for cargo security must be established is also similar. Therefore, it is necessary to establish a cooperation system by simplifying problems such as cumbersome and redundant authentication procedures and on-site verification through coordination of security requirements for mutual recognition between the two systems. As a result, it is necessary to establish a process for coordinating security and customs' supply chain security program and maximize the effect of harmonizing supply chain security by strengthening the linkage between known consignors and AEO.

Home networking and its security issues are directly related. Previous studies have shown that home-network and understanding the security of it is a problem for non-technical users. The existing network management tools or ISP adapter tools are far too technical and difficult to be understood by ordinary home-network users. Its interface is not non-technical user-directed and does not address the home user's needs in securing their network. This paper presents an interactive security monitoring tool, which emphasizes support features for home-network users. The tool combines an interactive visual appearance with a persuasive approach that supports sustainability. It is not only an easy-to-use tool for all categories of home-network users but also acts as a monitoring feature for the user to secure their home-network.

Today, due to the development of the 4th industrial revolution such as artificial intelligence, the security threat of the military organization is increasing. A study that can contribute to complying with military security is needed by studying the effects of influence factors occurring in this changing or newly emerging security environment on information security stress and security compliance behavior intention. In previous studies, task overload, task complexity, task uncertainty, and task conflict were extracted among environmental influencing factors that cause security stress. We empirically analyzed how these influencing factors affect security stress and whether they play a mediating role in security stress. As a result of the analysis, it was analyzed that the security stress was affected in the order of task overload, task conflict, and task uncertainty. Information security stress did not significantly affect security compliance behavior intention, but it was found to mediate the effect of task overload on security compliance behavior intention. This causes information security stress due to heavy security work in the military organization, which ultimately leads to lower security compliance behavior. Therefore, the security policy to manage this situation should be promoted first.

As the emerged importance and awareness for information security, It is being implemented by each industrial sector to protect information assets. In this paper, we analyze the information security checklists or security ratings criteria to derive similarity and difference in context which used to knowledge network analysis method. The analyzed results of all checklists (ISMS, PIMS, 'FSS', 'FISS', 'G') are as follows : First, It is common factors that the protection of information systems and information assets, incident response, operations management. Second, It deals with relatively important factors that IT management, the adequacy of audit activities in the financial IT sector including common factors. Third, the criteria of ISMS contains the majority of the contents among PIMS, 'FSS', 'FISS'and 'G'.
