This is an extended paper, focusing on the cost management for the organizations dealing with the crucial issues of security systems. Information Technology (IT) is an important and irreplaceable need of society and all working sector's success depends on IT to a greater extent; therefore maintaining security features is one of the most important aspects of IT. When security in the IT sector is discussed, Patch Management (P.Mgnt) has to be taken under account. P. Mgnt includes many concerns and areas to be described for IT security such as methods and problems in updating patch, methods of reducing security risks with P.Mgnt, methods of achieving economies of scale by controlling the operational costs and taking decisions in investing as and when necessary. This paper presents a general definition of Patch management, its benefits and management of working cost through theoretical models, also the paper gives methods of feeding techniques for microstrip patch antenna MPA, showing the contracting and non contracting methods.

Information security management systems (ISMSs) are used to manage information about their customers and themselves by governments or business organizations following advances in e-commerce, open networks, mobile networks, and Internet banking. This paper explains the existing ISMSs and presents a comparative analysis. The discussion deals with different types of ISMSs. We addressed issues within the existing ISMSs via analysis. Based on these analyses, then we proposes the development of an information security management evaluation system (ISMES). The method can be applied by a self-evaluation of the organization and an evaluation of the organization by the evaluation committee. The contribution of this study enables an organization to refer to and improve its information security levels. The case study can also provide a business organization with an easy method to build ISMS and the reduce cost of information security evaluation.

The private security will overcome the limit of public police system and implement a small and efficient government concept. Especially in recent years, this security system has naturally been expanded in its functions from crime prevention to prevention of disasters. To manage the emergency by the private security industry, the private security services to involve some peculiarity and specialty. The policy agenda of private security industry for crisis management are suggested. First of all, to provide quality services for emergency management, the guards from private organizations should receive professional education and training to secure the specialty. Second, we need to improve the quality of security instructors with intensive education system for them. Security instructors should be able to effectively handle lots of different matters in the fields of security, but examination of the current curriculum of education for security instructor indicates that there is not much chance of it. Third, must be natural in light that the private organizations have some limitations in their operational capabilities and scopes. Private security duties are well established in cooperation with related institutions such as the police. Lastly, development of high quality crisis management commodities in the private security becomes even more significant. The government should be determined to make an effort to grow the private industry and foster a political environment for the same purpose.

Policy-Based Network Management (PBNM) architecture is to meet various needs of network users and to provide effective management facilities in distributed and large scale networks to network managers. In PBNM, network managers perform network management operations by stipulating a set of rules rather than control each network component. On the other hand, providing security services such as authentication, privacy of messages as well as a new flexible and extensible administration framework, SNMPv3 enables network managers to monitor and control the operation of network components more secure way than ever before. Despite of its enhanced security services, SNMPv3 has difficulties in managing distributed, large-scaled network because it does not provide centralized security management facilities. In this paper, we propose a new security model called Role-based Security Management model (RSM) with security management policy to support scalable and centralized security management for SNMP-based networks. Also, the structure and the operation of the security system as well as the efficiency analysis of RSM in terms of security management are also described.

As Korea's industrial competitiveness and technological prowess increase, collaboration and technical exchanges with contracting companies are increasing. In an environment where cooperation with the contracting company is unavoidable ordering companies are also striving to prevent leakage of technologies through various security systems, policy-making and security checks. However, although the contracting companies were assessed to have a high level of security management the leakage of technical datas are steadily increasing. Issues are being raised about the effectiveness of the security management assessment and the actual security management levels. Therefore, this study suggested a security management system model to improve security management efficiency in the general contract structure. To prove this, analyze the efficiency of 36 contractor companies for the technical datas security management system using the DEA model. The results of the analysis are reflected in the assessment results. Lastly, suggestions for improving the effectiveness of the technical datas security system are proposed.

This study expands the current body of research by exploring multiple scenarios of insufficient and excessive IT security investments caused by interdependent risks and the interplay between IT security investments and cyber insurance. A key finding is that organizations experiencing interdependent risks with different types of cyber attacks (i.e., targeted and untargeted attacks) use different strategies in making IT security investment decisions and in purchasing cyber insurance policies for their information security risk management than firms that are facing independent risks. The study further provides an economic rationale for employing insurance mechanisms as a risk management solution for information security.

The security risk management used by some service providers is not appropriate for effective security enhancement. The reason is that the security risk management methods did not take into account the opinions of security experts, types of service, and security vulnerability-based risk assessment. Moreover, the security risk assessment method, which has a great influence on the risk treatment method in an information security risk assessment model, should be security risk assessment for fine-grained risk assessment, considering security vulnerability rather than security threat. Therefore, we proposed an improved information security risk management model and methods that consider vulnerability-based risk assessment and mitigation to enhance security controls considering limited security budget. Moreover, we can evaluate the security cost allocation strategies based on security vulnerability measurement that consider the security weight.

The purpose of this study was to add CPTED to the information security area. The control items of ISO 27001 (11 types) and the application principles of CPTED (6 types) were mapped. And the relevance between the items was verified through the FGI meeting through 12 security experts. As a result of the survey, the control items with a relevance of at least 60% on average are security policy, physical and environmental security, accident management, and conformity. As a result, the comprehensive policy was shared with CPTED's items as a whole. The specialized control items are security organization, asset management, personnel security, operation management, access control, system maintenance, and continuity management. However, specialized control items were mapped with each item of CPTED. Therefore, information security certification and septed are related. As a result, environmental security can be added to the three major areas of security: administrative security, technical security, and physical security.

Recently, the importance of research and development for technological innovation is increasing. The rapid development of research and development has a number of positive effects, but at the same time there are also negative effects that accelerate crimes of information and technology leakage. In this study, a research security level measurement model was developed that can safely protect the R&D environment conducted at the organizational level in order to prepare for the increasingly serious R&D result leakage accident. First, by analyzing and synthesizing security policies related to domestic and overseas R&D, 10 research security level evaluation items (Research Security Promotion System, Research Facility and Equipment Security, Electronic Information Security, Major Research Information Security Management, Research Note Security Management, Patent/Intellectual Property Security Management, Technology Commercialization Security Management, Internal Researcher Security Management, Authorized Third Party Researcher Security Management, External Researcher Security Management) were derived through expert interviews. Next, the research security level evaluation model was designed so that the derived research security level evaluation items can be applied to the organization's research and development environment from a multidimensional perspective. Finally, the validity of the model was verified, and the level of research security was evaluated by applying a pilot target to the organizations that actually conduct R&D. The research security level evaluation model developed in this study is expected to be useful for appropriately measuring the security level of organizations and projects that are actually conducting R&D. It is believed that it will be helpful in establishing a research security system and preparing security management measures. In addition, it is expected that stable and effective results of R&D investments can be achieved by safely carrying out R&D at the project level as well as improving the security of the organization performing R&D.
