  • And were the prevalence of smartphones is the Big Data era, such as Facebook or Twitter, SNS (Social Network Service) routine is used in the real world. Take advantage of the analysis, and to extract and utilize developed in the Apache Foundation Hadoop (Hadoop) without abandoning the SNS unstructured data here. Hadoop is an open source framework that can handle large amounts of data. Hadoop has been introduced in the domestic corporate and commercial development and Compared to the technology development Hadoop has been pointed out that the lack of security sector. In this paper, we propose a method to enhance the security and vulnerability analysis of security technologies and Hadoop.

  • In recent years, major security data such as research data and confidential documents have been leaked to the outside due to the carelessness of the companies and research institutes performing IT related services such as information technology projects and research and development of financial institutions, companies and public institutions is. Leakage cases are caused by leakage of personal information due to lack of security management of information system maintenance companies, such as unauthorized leakage or storage of related materials in outsourcing service process. In this paper, we analyzed the types and management status of service business through the environmental survey of corporate informatization business and analyzed the problems in development and maintenance using external service companies. Furthermore, in this paper, we provide an information system service that focuses on the business activities based on the items considered, and at the same time, it provides the informatization service for companies that can prevent infiltration of viruses and hacking from the outside. This paper presents a methodology for enhancing security for the system construction.

  • This paper reviews the current studies about the current secure OS, security module and SELinux, and suggests Linux access control module that uses the user discriminating authentication, security authority inheritance of subjects and objects, reference monitor and MAC class process and real-time audit trailing using DB. First, during the user authentication process, it distinguishes the access permission IP and separates the superuser(root)'s authority from that of the security manager by making the users input the security level and the protection category. Second, when the subjects have access to the objects through security authority inheritance of subjects and objects, the suggested system carries out the access control by comparing the security information of the subjects with that of the objects. Third, this system implements a Reference Monitor audit on every current events happening in the kernel. As it decides the access permission after checking the current MAC security attributes, it can block any malicious intrusion in advance. Fourth, through the real-time audit trailing system, it detects all activities in the operating system, records them in the database and offers the security manager with the related security audit data in real-time.

  • Modern society is information-oriented society that allow letters in electron, telecommunication, computer, highly Information-Communication and information processing by great development of semi-conductor technologies. All businesses are depending on computer. Also, Great many user according to development who is worth watching eagerly of computer network and utilization of database and technology could collect, search, handle, transmit and store data at the same time using computer. But, while processing and use of information that use computer become convenient, exposure of data became serious relatively. For these reason, Security problem of data that need the secret rose. Accordingly, new encryption methods to use computer for security of data are presented and are developed continuously. Studied about DES, 3DES, RSA, ECC algorithm to select cipher algorithm to use in research hereafter in this treatise.

  • The importance of this Paper is to develop a standard Performance evaluation model and scenario for the secure OS. According to the scenario that was conducted for Performance evaluation, benchmarking was Performed. All the benchmarking result was thoroughly analyzed. Our result contribute to evaluating Secure 05 that contains various security policy affecting system Performance. In this paper, it is expected to Provide guidelines of secure operating system for the consumer, developer and evaluator. It will also contribute to the systematic basis for evaluation of security 05 and the promotion of domestic information security industry by retaining basic technology for international trends.

  • If Industrial state-of-the-art technology that made through IT convergence should be to build safely environment that can protect then IT technology and manufacturing industry become convergence and a growth engine become stable positioning. In each industry, there has been a steady effort for the industrial security. However, they introduced only managerial/technical/physical countermeasures. Therefore, it is difficult to find a reference point as industrial security necessity, protecting coverage and things and so on. It is to lack that academic research in industrial security for protecting industrial technology. In detail, a clear definition lack for industrial security. And target range classification lack for industrial security studies. In this study, we redefined the concept of industry security through previous studies. Academic classification designed industrial security studies through delphi method. we analyzed industry security trends based industrial security studies classification and presented domestic industry research orientations.

  • Recently, The cloud computing technology is emerging as an important issue in the world and the cloud computing has attracted much attention to the technology about carbon dioxide reduction. However, Unlike to the positive aspects of a cloud computing are included several security vulnerabilities. For this reason, the carbon dioxide reduction of a cloud computing technology has a differences. Therefore, this paper will be analyzed to the carbon dioxide emission factors of a cloud computing through the cloud case studies related $CO_2$ emissions and experiments measured of $CO_2$ emissions a security system. and In the future, this is expected to be utilized as a basis for the security design and performance improvement.

  • The purpose of this study is to analyze the influence which affects security performance of registered security guards hired by government buildings via job engagement so that basic data can be provided to improve their security performance. To accommodate this study, a survey was conducted from November 26th to December 27th, 2019 through the cooperation of registered security guards working in government buildings in Seoul, Gwacheon, Daejeon, and Sejong. A total of 234 survey sheets were collected and 28 sheets out of them had missing data or incomplete data so a subsequent total of 206 survey sheets were used in this analysis. SPSS 23.0 was applied making use of the collected data for frequency and descriptive statistics analysis, trustworthiness analysis, exploratory factor analysis, and correlation analysis. By applying AMOS 23.0, a means to examine the structural relation between organization, job engagement, and security performance were able to be analyzed. The result of this study is as follows. First, it was found that organizational justice gives a meaningful positive (+) influence on job engagement for registered security guards. Second, it was found that job engagement for registered security guards gives them a meaningful positive(+) influence in their security performance. Third, it was found that organizational justice does not give any meaningful influence on security performance directly. Fourth, organizational justice does not give any meaningful influence on security performance directly but it gives meaningful positive(+) influence on security performance via job engagement as it takes the role of full mediation variable. Based on the results, in order to maximize security performance of registered security guards, this study recommends that government building administrators to try their best to propose to the National Assembly a proposition for Police Assigned for registered security guards Act to be legalized in order to improve the leveling system of registered security guards so that registered security guards can have more job engagement.
