Today, it is an information society where a large number of users access and view important data in a large number of information assets as needed. In this complexity, techniques related Identify Management are being applied, in order to verify authorized user access to important information assets and manage of history. But, the ability access to sensitive information using account has the disadvantage of being able to open the way for information to the attacker when it is hijacked. Thus, in this paper, we propose a secure Identify Management System that can control the use of accounts based on the attitude of the account holder, but also enhances the security and does not hinder the convenience.

Convergence ethics education for digital culture in cyberspace is limited to specific areas such as personal information and copyright. Education on the ability to accept information and provide information in cyberspace in which digital natives communicate, share and exchange is inadequate. As a result, the dysfunction of abusing the personal information of others without recognizing the importance of information security has recently emerged as a social problem. In this study, among digital netizen who communicate and exchange information the most in cyberspace, digital literacy education was conducted for students in the first and second grades of university, and then they investigated the change in information security perception. Based on this, we intend to prepare fundamental measures for systematic cultivation of digital literacy education necessary for the Digital Cultural Society.

Identity and access management in cloud computing is one of the leading significant issues that require various security countermeasures to preserve user privacy. An authentication mechanism is a leading solution to authenticate and verify the identities of cloud users while accessing cloud applications. Building a secured and flexible authentication mechanism in a cloud computing platform is challenging. Authentication techniques can be combined with other security techniques such as intrusion detection systems to maintain a verifiable layer of security. In this paper, we provide an interactive, flexible, and reliable multi-factor authentication mechanisms that are primarily based on a proposed Authentication Method Selector (AMS) technique. The basic idea of AMS is to rely on the user's previous authentication information and user behavior which can be embedded with additional authentication methods according to the organization's requirements. In AMS, the administrator has the ability to add the appropriate authentication method based on the requirements of the organization. Based on these requirements, the administrator will activate and initialize the authentication method that has been added to the authentication pool. An intrusion detection component has been added to apply the users' location and users' default web browser feature. The AMS and intrusion detection components provide a security enhancement to increase the accuracy and efficiency of cloud user identity verification.

Capitalism is based on a material desire of the human being. the social control of capital value and the management of capital ability reflects the actual condition of the capitalism well. The unconstrained growing and the expansion of capitalism, it finally lost social meaning and an importance of human being element and the safety of the civilian life, began to threat the security of citizen by forming over the material center structure of society. Improving human life quality and material richness on their life leads positive factor of capitalism whereas is causing several crimes through the society which is being threatened around a human being life for a negative factor of the capitalism. Therefore capitalistic social system has offered both a positive factor 'growing' and 'richness' and that of a negative 'structural poverty' and 'lack of security' and they have been remaining the assignment of capitalism 'poverty' and 'security' by settlement in the society for a extremely phenomenon of both sides. The objective of this research is to build its study theory and establish its causal relation by illuminating for the social environment of capitalism for a private guard or a development background of the civil security contributing for citizen security, as well as gets the clue of the development possibility of the civil guard and escort field and the development of capitalism. In Korea because their recognition of the study approach and the social safety for social security control function is still staying first step and our daily life is annoying from various threat of the society, many studies and the realistic necessity of experience related with social security is being studied. In addition, The development possibility of the civil guard and defense at the civil field which will be keep the social security has a wide position but its study approach and realistic comprehension is still in insufficient condition. Consequently, this research is started to grasp the security of civil fiend and to grope a development possibility through the research of capitalism.

Quantitative rise and qualitative seriousness in crime have limitation to preventing crime just with public police security. Ultimately, in order for private security guard to fulfill the duty of preventing crime, its members' excellent quality and ability need to be preceded. This change in the environment of crime prevention came to demand professionalism in the security field. Furthermore, it became an opportunity of being emerged the necessity of specialist qualification. For this, first, there is a need of reinforcing the public confidence of the security guard association, and of vitalizing a certificate of qualification. Second, qualification functions as linking education and labor market. Thus, many qualification acquisitors need to strengthen direction that the security guard company can reflect and utilize this. Third, there is a need of positively supplementing the result of utilizing qualification or the insufficient management system so that the private security guard qualification system can be recognized as the qualification system of being authorized by the country.

As industries converge in recent years, the impact of the use of convergence tools among industries on the security of the organization is increasing. However, organizational members lack the ability to adapt to introduction of new system because they are operating business around existing systems, and thus, security considerations are an environment that will inevitably emerge as a follow-up priority. In this study, we studied cost-effective options for factors that should be considered first in order to establish a security system for small and medium-sized healthcare institutions in the healthcare convergence industry. Specifically, the current legal system was considered and the security status was analyzed through prior research, and the necessary security solution/system was derived from small and medium-sized healthcare institutions. In addition, it analyzed relative priorities for cost-efficient deployment of security systems to those involved in small and medium-sized healthcare institutions in actual business environments and presented measures to establish a overall security.

Analyzing network traffic is the basis of dealing with network security issues. Most of the network security systems depend on the feature selection of network traffic data and the detection ability of malicious traffic in network can be improved by the correct method of feature selection. An FAFS method, which is short for Fuzzy Association Feature Selection method, is proposed in this paper for network malicious traffic detection. Association rules, which can reflect the relationship among different characteristic attributes of network traffic data, are mined by association analysis. The membership value of association rules are obtained by the calculation of fuzzy reasoning. The data features with the highest correlation intensity in network data sets are calculated by comparing the membership values in association rules. The dimension of data features are reduced and the detection ability of malicious traffic detection algorithm in network is improved by FAFS method. To verify the effect of malicious traffic feature selection by FAFS method, FAFS method is used to select data features of different dataset in this paper. Then, K-Nearest Neighbor algorithm, C4.5 Decision Tree algorithm and Naïve Bayes algorithm are used to test on the dataset above. Moreover, FAFS method is also compared with classical feature selection methods. The analysis of experimental results show that the precision and recall rate of malicious traffic detection in the network can be significantly improved by FAFS method, which provides a valuable reference for the establishment of network security system.
