The leakage of toxic chemicals impact seriously on human being and environment, therefore during their treatment process, a proper management system is necessary to control their toxic effect. This study was designed to suggest the management regulation that supports business managers and facilities management. There are no extra regulation to control emergency accidents and terrors in chemical facilities. Developed countries like USA operate the management standards to control the toxic chemical and facilities according to their toxicity and processes. In order to solve this problem, we have analysed the advanced nations standard methods of security in chemical plants to study the new security management regulation which helps to prevent the chemical accidents. Especially, in USA, CCPS (Center for Chemical Process Safety), SVA (Security Vulnerability Assessment) and RBPSs (Risk-Based Performance Standards) of DHS (Department of Homeland Security) were invest I gated. On the basis of the results, we have suggested the application methods of the security and safety regulation in Korea.

As Cyber threats are rising, the scope of information Security (IS) is extending from technical protection of a single information system to organizational comprehensive IS capability. The ministry of National Defense (MND) has established the IS evaluation for defense organization in 'the Directive for Defense Informatization Affairs.' However, no information about an evaluation method, process and organization is provided. We surveyed information security management system (ISMS) and related best practices in public sector and other countries, and analysed the military information security affairs. Thus, this paper recommends the IS evaluation method and process. The trial IS evaluation is in progress this year and the MND will expand this IS evaluation to the entire organization.

Recently, mobile devices have been widely used. Therefore, the service users want that are not constrained by time and space. Among them, electronic payment services, mobile finance service is enjoying a tremendous popularity. The FinTech is the result of the fusion of finance and ICT(Information & Communication Technology). Security experts is pointed the FinTech security risk. New technology and Innovative FinTech services are even available, Insecure FinTech services is insignificant. In this paper we were surveyed market and product trends of FinTech and analyzed the threats about FinTech. Also, we analyzed the security considerations for FinTech using a questionnaire. As a result, users considers secure payment process and privacy. Therefore, we proposed security considerations for each vulnerability. So, we must be resolved of security technology and policy issues. If establishing a secure payment process and the unclear legal issue is resolved, FinTech service will provide a secure financial services to the user.

The airport processes are restricted by some limits of performance objects as size of airport, ability of human resources, capacity of facilities and operational rules. These limitations make passenger handling difficult when passenger numbers increase. In order to solve this problem, we modeled the airport process and analyzed departure passenger arrival, scheduled security manpower under specific customer service level maintenance with mixed integer programming and validate the efficiency with simulation with adapting smart airport framework. We concluded that the airport management with information techniques can reduce waiting time within security and immigration process.

The absence of proactive information security management to ensure availability, accessibility and safety of information can bring serious risks to customers as well as to the organization's performance and competitiveness because improper security management undermines business continuity. This study analyzed the maturity of information security which affects the organizational performance. Through the literature reviews, a research model using the organizational performance as the dependent variable, the risk management process maturity and risk assessment process as independent variables and the information security policy indexes as moderate variables was proposed, and an empirical analysis was made on the basis of survey. The results showed that there was a high causal relationship between information security maturity and organizational performance. However, even if the proportions of information security staff ratio and the information security budget ratio increased, information security maturity did not affect organizational performance. It suggests that information security maturity affects organizational performance, but information security regulations have their limitation as being a catalyst to improve organizational performance.

Recently organizations identify information security as one of essential means for gaining competitive advantage. However, they do not actively increase investment in this area because they consider spending for information security as a cost rather than an investment. This is because organizations don't have a clear understanding of information security objectives which can be achieved through investment, and they don't have criteria for alternatives which can be considered in information security investment decision-making. In this paper we propose to model the decision-making process of information security investment by the AHP (Analytic Hierarchy Process). The results will show that availability is the most important criterion for the decision of information security alternatives, and intrusion detection is the most important information security alternative. We hope that the results of this paper provide a guideline for clear decision-making in information security investment.

As information services have been widely used in various environments, the knowledge information security sector plays a significant role in development and management of products and services, information privacy management, risk management and safety, etc. Thus, the process of acquiring knowledge information security professionals is getting more attention for promoting the stable and long-term development of the knowledge information security sector. This study identifies and analyzes the promising fields for the KISA Employment-Contract Master Program and suggests promotion strategies for knowledge information security professionals. By surveying participants and would-be participants, and interviewing experts, it is analyzed that 'mobile security' and 'convergence security' are the two most important fields to be included in the program.

Recently, internal information leaks is increasing rapidly by internal employees and authorized outsourcing personnel. In this paper, we propose a method to integrate internal control systems like system access control system and Digital Rights Managements and so on through expansion model of SIEM(Security Information Event Management system). this model performs a analysis step of security event link type and validation process. It develops unit scenarios to react illegal acts for personal information processing system and acts to bypass the internal security system through 5W1H view. It has a feature that derives systematic integration scenarios by integrating unit scenarios. we integrated internal control systems like access control system and Digital Rights Managements and so on through expansion model of Security Information Event Management system to defend leakage of internal information and customer information. We compared existing defense system with the case of the expansion model construction. It shows that expanding SIEM was more effectively.

Enterprise security management system proposed to properly manage heterogeneous security products is the security management infrastructure designed to avoid needless duplications of management tasks and inter-operate those security products effectively. In this paper, we defined the security policies using Z-Notation and the detection algorithm of policy conflict for managing heterogeneous firewall systems. It is designed to help security management build invulnerable security policies that can unify various existing management infrastructures of security policies. Its goal is not only to improve security strength and increase the management efficiency and convenience but also to make it possible to include different security management infrastructures while building security policies. With the process of the detection and resolution for policy conflict, it is possible to integrate heterogeneous security policies and guarantee the integrity of them by avoiding conflicts or duplications among security policies. And further, it provides convenience to manage many security products existing in large networks.
