Enormous losses of shareholders and consumers caused by the risks threatening today's business (e.g., accounting fraud and inside trading) have ignited the necessity of international regulations on corporate ethics and internal control, such as Basel II and SOX. Responding to these regulations, companies are establishing governance system, applying it consistently to the core competency of the company, and increasing the scope of the governance system. Recently occurred security related incidents require companies to take more strict accountability over information security. One of the results includes strengthening of legislation and regulations. For these reasons, introduction of information security governance is needed. Information security governance governs the general information security activities of the company (establishment of information security management system, implementation of information security solutions) in the corporate level. Recognizing that the information security is not restricted to IT domain, but is the issue of overall business, this study develops information security governance framework based on the existing frameworks and systems of IT governance. The information security governance framework proposed in the study include concept, objective, and principle schemes which will help clearly understand the concepts of the information security governance, and execution scheme which will help implement proper organization, process and tools needed for the execution of information security governance.

Information and Information processing systems must maintain a certain level of security during the total life cycle of Information. To maintain a certain level of security, security management processes are applied to software, automobile development, and the U.S. federal government information system over a life cycle, but theme of no similar security management process in Korea. This paper proposes a Korean-style security risk management framework to maintain a certain level of security in the total life cycle of information and information processing system in the defense sector. By applied to the defense field, we intend to present the direction of defense security work in the future and induce an shift in security paradigm.

In a dynamic IT environment, employees often utilize external IT resources to work more efficiently and flexibly. However, the use of external IT resources beyond its control may cause difficulties in the company. This is known as "Shadow IT." In spite of efficiency gains or cost savings, Shadow IT presents problems for companies such as the outflow of enterprise data. To address these problems, appropriate measures are required to maintain a balance between flexibility and control. Therefore, in this study, we developed a new information security management system called AIIMS (Advanced IT service & Information security Management System) and the Shadow IT Evaluation Model. The proposed model reflects a Shadow IT's attributes such as innovativeness, effectiveness, and ripple effect. AIIMS consists of five fields: current analysis; Shadow IT management plans; management process; education and training; and internal audit. There are additional management items and sub-items within these five fields. Using AIIMS, we expect to not only mitigate the potential risks of Shadow IT but also create successful business outcomes. Now is the time to draw to the Light in the Shadow IT.

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.

Recently, a lot of nations are establish and researches the u-City which ubiquitous technology based city, and u-City Management Center(UMC) is also establish and researches. Technical researches of UMC are increasing. However, administrator privilege management researches for UMC is not enough. If we don't manage to administrator privilege who can access and control all of information in UMC, security problems will be occurs. Therefore, in this paper, analyses of administrator privilege management security problems, and proposed administrator privilege management system classification.

In order to manage information security risk, various information security level evaluation and information security management system certification have been conducted on a larger scale than ever. However, there are continuous cases of infringement of information protection for companies with excellent information security evaluation and companies with excellent information security management system certification. The existing information security risk management methodology identifies and analyzes risks by identifying information assets inside the information system. Existing information security risk management methodology lacks a review of where cyber threats come from and whether security devices are properly operated for each route. In order to improve the current risk management plan, it is necessary to look at where cyber threats come from and improve the containment level for each inflow section to absolutely reduce unnecessary cyber threats. In addition, it is essential to measure and improve the appropriate configuration and operational level of security equipment that is currently overlooked in the risk management methodology. It is necessary to block and enter cyber threats as much as possible, and to detect and respond to cyber threats that inevitably pass through open niches and use security devices. Therefore, this paper proposes additional evaluation items for evaluating the containment level against cyber threats in the ISMS-P authentication items and vulnerability analysis and evaluation items for major information and communication infrastructures, and evaluates the level of security equipment configuration for each inflow.

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.
