기업은 기업의 비즈니스 정보를 보호하기 위해 정보보호 관리체계 구축, 정보보호 시스템 구축 및 운영, 취약점 점검, 보안 관제 등 다양한 정보보호 활동을 하고 있다. 기업 비즈니스를 위한 다양한 정보보호 활동들을 체계화한 것이 기업 정보보호 거버넌스라고 할 수 있으며, 이를 효과적으로 운영하기 위해서는 시스템화할 필요성이 있다. 본 연구에서는 기업 정보보호 거버넌스를 시스템화하기 위해 기존의 기업 정보 포털(EIP) 모델에 대해 알아보고, 이에 기반한 기업 정보보호 포털(EISP) 모델을 제시하고자 한다. 기업 정보보호 포털(EISP) 모델은 기업의 다양한 정보보호 활동인 기업 정보보호 거버넌스를 시스템화하여 정보보호부서의 활동을 지원하고 기업의 정보보호 활동이 정보보호부서만의 활동이 아닌 최고경영자부터 임직원까지 직접 참여할 수 있도록 통합된 환경을 제시한다.

Recently, many South Korean firms have suffered financial losses and damaged corporate images from the data breaches. Accordingly, a firm should manage their IT assets securely through an information security investment. However, the difficulty of measuring the return on an information security investment is one of the critical obstacles for firms in making such investment decisions. There have been a number of studies on the effect of IT investment so far, but there are few researches on information security investment. In this paper, based on a sample of 76 investment announcements of firms whose stocks are publicly traded in the South Korea's stock market between 2001 and 2017, we examines the market reaction to information security investment by using event study methodology. The results of the main effects indicate that self-developed is significantly related to cumulative average abnormal returns (CAARs), while no significant effect was observed for discloser, investment characteristics and firm characteristics. In addition, we find that the market reacts more favorably to the news announced by the subject of investment than the vendor, in case of investments with commercial exploitation. One of main contributions in our study is that it has revealed the factors affecting the market reaction to announcement of information security investment. It is also expected that, in practice, corporate executives will be able to help make an information security investment decision.

IT시대의 고도화로 인한 사이버 범죄는 지능화, 다양화, 고도화 되고 있는 가운데 보안 관제의 역할은 더욱 중요해졌다. 과거 방화벽이나 IDS 등 보안 장비에만 의존하던 방식과는 달리 실시간 감시를 통해 사이버 공격에 대한 대응을 하는 보안 관제 업무가 광범위해지고 그 역할 또한 중요하게 되었다. 현재의 사이버 위협에 대해 보안 장비만으로는 안정적인 방어를 할 수 없기 때문에 보안 장비를 운영 및 감시하고 실시간적인 대응을 할 수 있는 보안 관제의 업무가 필수 요소가 된 것이다. 본 연구에서는 네트워크 보안시스템을 효율적으로 구성하는 방법과 보안시스템을 실시간 운영하는 보안관제의 현황과 개선방안에 대해 다루고자 한다.

본 논문은 경비원 권리보호의 경비업법 수용제고 방안을 도출하는데 목적을 두고 있다. 이를 위해 민간경비원과 동일한 업무특성을 지니고 있는 청원경찰의 권리보호 양태와의 비교고찰을 통해 접근해 보았다. 분석결과, 경비원의 권리보호를 위한 경비업법의 수용내용을 제시하면 다음과 같다. 첫째, 경비원의 경제적 지위를 보장하는 기본적인 조항을 경비업법에 신설하여야 한다. 둘째, 경비원의 권한범위를 명확히 규정할 필요가 있다. 셋째, 경비원의 의무규정에서 위력이나 물리력의 범위를 명확히 할 필요가 있다. 본 규정 중 물리력 행사는 존치시키고 '위력과시' 부분은 삭제하여야 한다. 넷째, 경비원의 폭행에 대한 가중처벌 조항을 신설해야 한다. 끝으로 경비업법과 청원경찰법은 제정목적이나 성격 면에서는 상당히 차이를 갖기 때문에 단순한 법조항 도입 보다는 보호이익에 초점을 맞추어 도입하는 것이 바람직하다.

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.

In this paper, we propose to present a model of cloud security that has emerged as the biggest topic of cloud computing, replacing the traditional IT environment. While cloud computing is an extension of existing IT technology, security issues and threats can be applied to traditional security technologies. However, the biggest difference between a typical computing environment and a cloud computing environment is a virtualized environment with a hypervisor. Currently, there are many weaknesses in the virtualized environment, and there are few related security products. In order for a cloud computing environment to function as a reliable IT environment, we expect more research on hypervisor-based security technologies, and we expect to secure safer cloud services through a secure model over the next generation of new-based networks.

Information system (IS) security continues to present a challenge for firms. Especially, IT security accident is recently taking place successively in the financial sector. Thus, a comprehensive measure on this is demanded. A large part of a research on security relies upon technical design in nature and is restrictive in a consideration of person and organizational issue. To achieve a goal of firm security, it is possible with an effort of organizational management and supervision for maintaining the technical and procedural status. Based on a theory of accountability, we propose that the security countermeasures of organization lead to an increase in accountability and reduction in risk of IT security in a financial firm and further to firm performance like promotion in firm reliability. In addition, we investigate which difference a theoretical model shows by comparison between South Korean and American financial firms. As a result of analysis, it found that South Korea and America have significant difference, but that a measure on the financing IT security is important for both countries. We aim to enhance interpretability of a research on security by comparatively analysis between countries and conducting a study focus on specific firm called financial business. Our study suggest new theoretical framework to a research of security and provide guideline on design of security to financial firm.

Intentional information systems (IS) misuse is a serious problem in many organizations. This study aims at developing the theoretical framework of deterring IS misuse on the basis of Nagin's General Deterrence Theory (GDT) which is very famous in the area of socio-criminology. Applying GDT to the IS misuse situation could be reasoned that the perceived certainty and the perceived severity of sanctions associated with committing IS misuse have positive impact on deterring the deviant behaviors. Also, these two constructs (certainty of sanctions and severity of sanctions) could be inferred to be influenced by the four types of IS security countermeasures (security policies, security awareness program, monitoring practices and preventive security software) derived through critically reviewing IS security-relevant literature. The proposed research model and ten hypotheses were empirically analysed using structural equation modelling with the data collected by conducting a questionnaire survey of staff members in business organizations in Korea. As a result, it was found that five ones of ten hypotheses were supported. It is thought that this study makes theoretical contribution to expanding research area of IS security and also has strong implications for IS security management practices within organizations.

The private security has forty years history and it seems not to have points in exteriors. But it has many points in interior. If these points improved, our private security can develop. I discuss the development of the private security in Chapter 2 and the points in Chapter 3, and conclude in the last Chapter. If we follow the precepts, and develop a good points and improve a week points, the future of our private security will be better.
