In order to protect the business information of the enterprise, the company is engaged in various information security activities, such as establishing an information security management system, establishing and operating an information security system, checking vulnerabilities and security controls. It is an enterprise information security governance that organizes various information security activities for enterprise business, and it needs to be systematized to operate them effectively. In this study, to systematize the enterprise information security governance, we would like to explore the existing Enterprise Information Portal(EIP) model and propose an Enterprise Information Security Portal(EISP) model based on it. The Enterprise Information Security Portal(EISP) model provides an integrated environment for supporting the activities of the information security departments by systemizing the enterprise information security governance, which is a variety of information security activities of the enterprises, so that the information security activities of the enterprises can participate directly from CEO to executives and employees, not just from the information security departments.

Until now, most of the evaluation systems have performed evaluation with an emphasis on in-formation security products. However, evaluating information security level for an enterprise needs analysis of the whole enterprise organization, and a synthetic and systematic evaluation system based on it. In this study we subdivided the information security elements of the whole enterprise such as planning, environment, support, technology, and management; developed indices based on them; finally, made the information security level of the whole enterprise organization possible to be measured. And we tried to grasp the information security level of the whole enterprise organization and develop an evaluation system of information security level for suggesting a more developing direction of information security.

Cloud computing has become one of the most important technologies for reducing cost and increasing productivity by efficiently using IT resources in various companies. The cloud computing system has mainly been built for private enterprise, but public institutions, such as governments and national institutes, also plans to introduce the system in Korea. Various researches have pointed to security problems as a critical factor to impede the vitalization of cloud computing services, but they only focus on the security threats and their correspondents for addressing the problems. There are no studies that analyze major security issues with regard to introducing the cloud computing system. Accordingly, it is necessary to research the security factors in the cloud computing given to public institutions when adopting cloud computing. This research focuses on the priority of security solutions for the stepwise adoption of cloud computing services in enterprise environments. The cloud computing security area is classified into managerial, physical and technical area in the research, and then derives the detailed factors in each security area. The research derives the influence of security priorities in each area on the importance of security issues according to the identification of workers in private enterprise and public institutions. Ordered probit models are used to analyze the influences and marginal effects of awareness for security importance in each area on the scale of security priority. The results show workers in public institutions regard the technical security as the highest importance, while physical and managerial security are considered as the critical security factors in private enterprise. In addition, the results show workers in public institutions and private enterprise have remarkable differences of awareness for cloud computing security. This research compared the difference in recognition for the security priority in three areas between workers in private enterprise, which use cloud computing services, and workers in public institutions that have never used the services. It contributes to the establishment of strategies, with respect to security, by providing guidelines to enterprise or institutions that want to introduce cloud computing systems.

Very various intrusion by development of systems that is based on network is spread. To detect and respond this intrusion, security solutions such as firewall or IDS are bringing and management of security system that load these becomes more harder. Moreover, because environment of systems that require security is various, hard to manage establishing suitable security policy Therefore, need model about enterprise management of various security system and intrusion detection of each systems and response. In this paper, improve PBNM structure that manage wide network resources and presented suitable model in intrusion detection and response of security system. Also, designed policy-based enterprise security management system for effective intrusion detection and response by applying presented model to enterprise security management system.

The existing enterprise information security activities were centered on the information security organization, and the top management considers information security and enterprise management to be separate. However, various kinds of security incidents are constantly occurring. In order to cope with such incidents, it is necessary to protect information in terms of business management, not just information security organization. In this study, we examine the existing corporate governance and IT governance, and present an information security governance model that can reflect the business goals of the enterprise and the goals of the management. The information security governance model proposed in this paper induces the participation of top management from the planning stage and establishes information security goals. We can strengthen information security activities by establishing an information security plan, establishing and operating an information security system, and reporting the results to top management through compliance audit, vulnerability analysis and risk management.

Intranet is an enterprise network using Internet protocols as communication standard and HTML as content standard. The Internet is like a house built on information water. It has a lot of strong points as a future enterprise network. However, companies wish to have confidence in its functional and economic effectiveness and security before adopting it. The security issue especially is a problem to solve inevitably. Enterprises will hold back to adopt Intranet unless there are enough security counter plans and countermeasures against vulnerabilities of Intranet(it is the wise decision !). Nevertheless the researches related to Intranet has been concentrated on techniques for building it. In this paper, we focus the security aspect of Intranet. Intranet security must be considered on the whole from structure design to users' services. We propose a security-based Intranet structure and security management system.
