Although Firms have been increasing their information security significantly to handle increased security risks, the effects of information security were not well understood. This study aims to investigate the market value of information security by employing the event study methodology. Our research also explores how market responses vary depending on the type of information security announcements. We collected 177 firm-level information security announcements between 2001 and 2017 in South Korea. For all samples, our results indicate that the stock market positively reacts to information security announcements. We also conducted subsample analysis and found that while information security certification announcement has a positive impact on the stock market, information security activities (e.g. award, information security system) announcement had no impact on the stock market. Our study adopted a novel approach (i.e. event study) for investigating the effects of information security and found that information security investment positively affects firm value. Our results allow managers to measure the effects of information security investment and help them make right decisions on information security investment.

Since Electronic Security System is introduced in Korea in 1981 by foreign technology, Security market has been increasing considerably during short period, and It performs it's security roles well in place of security guards. As electronic and communication technology is highly developed, Electronic Security System and security market structure is changing naturally. Especially high-tech mobile communication technology will change the method of Electronic Security business. Also the pattens of residence and life style, such as the trend toward nuclear family and single life could effect security market. In recent year, new business models that apply the mobile phone and internet is appeared. Although Electronic Security System is changed by the changes of technology, It is very difficult to change the basic elements, such as sensing, alarm signal transfering, and response. The rate of increase of Electronic Security market is expected to matain it's increase pace for the time being. But the development of new system for new protectes such as childeren, old person, vehicle rather than immovable facility is necessary to prepare for the continuous competition.

This paper presents a two-stage market auction model in a pool-based electricity market, which explicitly takes into account the system network security. The security network-constrained market auction model considers the use of corrective control to yield economically efficient actions in the post-contingency state, while ensuring a certain security level. Under this framework, the proposed model shows not only for quantifying the correlation between secure system operation and efficient market operation, but also for providing transparent information on the pricing system security for market participants. The two-stage market auction procedure is formulated using Benders decomposition (BD). In the first stage, the market participants bid in the market for maximizing their profit, and the independent system operator (ISO) clears the market based on social welfare maximization. System network constraints incorporating post-contingency control actions are described in the second stage of the market auction procedure. The market solutions, along with the BD, yield nodal spot prices (NSPs) and nodal congestion prices (NCPs) as byproducts of the proposed two-stage market auction model. Two benchmark systems are used to test and demonstrate the effectiveness of the proposed model.

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.

본 연구에서는 타 기술과의 융합을 통하여 그 영역이 지속적으로 확대되고 있는 정보보호 산업의 글로벌 시장동향을 분석하였다. 국내 정보보호 산업 시장은 2013년 현재 국내시장이 세계시장에서 차지하는 점유율이 매우 낮다는 점과 수차례의 보안사고로 인한 경각심 고조, 물리보안 수출의 확대 등의 요인을 고려하면 세계 정보보호 산업에 비해 높은 성장률을 보일 것으로 전망된다. 주목해야 할 점은 국내 시장은 제품시장이 주도하지만, 세계시장은 서비스 시장이 주도할 것이라는 전망이다. 따라서 국내 정보보호 산업의 현재의 부진을 극복하기 위해서는 상대적으로 부가가치가 높은 서비스 시장에 보다 중점을 둔 시장육성 전략이 요구된다.

Recently, many Korean firms have suffered financial losses and damaged firm's trust due to information security incidents. Hence, a lot of firms have realized the importance of the information security. In particular, the demand for information security certification has increased. This study examined the effect of information security certification using the event study methodology. Our research shows that the announcement of the information security certification significantly influences the market value of the corresponding firm. The certified firms rise, on average, o.4993% (-2 day), 0.5462% (+1 day) of their market value. Further, we found that the financial sector in our data showed a 1.4% higher abnormal returns than the nonfinancial sector. On the other hand, whether a firm first acquired the information security certification is not significant. Our paper presents that it is possible to analyze the effect of the information security certification using the event study. We are expected to be used in making a decision for the investment of information security. Also, our results indicate that the firm which have acquired the information security certification should actively announce that fact.

This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.

2000년대 이후 전 세계적으로 시큐리티 시장은 매년 7${\sim}$8%의 지속적인 성장을 계속하고 있으며, 한국은 그 가운데에서도 향후 산업발전이 빠르게 이루어질 대표적인 국가로 꼽히고 있다. 이 연구는 국내 시큐리티 시자의 향후 성장가능성을 전명하기 위해 그 동안 국내 시큐리티 산업의 발전에 기여한 요인들과 향후 시큐리티 수요에 영향을 미칠 새로운 사회, 경제적 환경변화를 살펴보고자 하였다. 이를 위해 시큐리티, 범죄, 경찰, 인구, 사회, 경제, 정보화 등과 관련한 다양한 통계자료를 수집하여 분석에 이용하였다. 범죄의 증가와 국가경찰력의 한계, 경제성장과 소득 수준의 향상, 중산층의 확대 등은 국내 시큐리티 시장의 성장에 중요하게 작용하였으며 향후에도 그 영향력을 지속할 것으로 보인다. 한편 새로운 사회, 경제적 변화에 의해 시큐리티 수요가 확대될 것으로 전망된다. 우리나라의 빠른 노령화속도와 1인 가구의 증가, 여성의 경제활동증가와 같은 인구구조의 변화는 가구와 개인의 범죄방어력을 감소시키며 안전에 대한 사회적 욕구를 증가시킬 것으로 보인다. 또한 전 세계적으로 진행되고 있는 글로벌 경제와 지구촌화현상은 국내에도 물적 인적교류로 인한 검색과 감시 기술에 대한 수요를 증가시킬 것이며, 국내의 눈부신 IT기술의 발전 또한 시큐리티 시장 확대에 기여하는 새로운 환경으로 작용할 것으로 보인다. 이 글은 시큐리티 시장을 수요를 촉진하는 사회경제적 변화를 중심으로 다루었으며, 이로 인해 시큐리티 사업의 성장에서 고려해야 할 제도적${\cdot}$법률적 환경, 기술수준, 정치적 환경 등은 분석에 포함하지 못하는 한계를 지니고 있다.인인 것으로 나타났다.

본 연구에서는 한국과 세계의 정보보안 산업의 상호 비교 분석을 통해 한국 정보보안 산업의 위상을 파악하는 한편, 정책작 시사점을 제시하였다. 세계 정보보안 산업에서는 서비스시장이 제품시장에 비하여 매출이 훨씬 크고 시장 매력도도 큰 것으로 나타났지만, 한국의 경우 정반대의 결과가 나타났다. 이와 같은 연구결과는 소득 창출력이 미약한 정보보안 제품의 부가가치를 높이기 위한 대책 마련이 시급하며, 정보보안 산업의 주력 시장을 제품시장에서 서비스시장으로 구조개편을 서두를 필요성이 있다는 사실을 시사한다.
