Purpose Targeting Korean companies listed on Korean securities markets (i.e., KOSPI and KOSDAQ markets), this study aims to shed lights the effects of personal information security breaches on stock prices of information security companies. Interestingly, this study is, to the best of our knowledge, the first to examine the information transfer effect on personal information security breaches of companies. Design / Methodology /Approach To examine the information transfer effect of personal information security breaches, our study employs the event study commonly used in financial studies. To this end, we investigate a variety of events of personal information security breaches of companies listed on the KOPSI stock market and the KOSDAQ market. We collect the total samples of one hundred and twelve with forty seven of events of personal information security breaches by thirty companies and sixty five of information security companies. Findings The principal findings from the empirical study are as follows. First, for companies of personal information security breaches, our event study presents the significantly negative AAR (averaged abnormal return) value on the event day at the 5 % level and the highly significant negative CAAR(cumulative averaged abnormal return) value on the event day and the day after the event day at the 1 % level. The results suggest that personal information breaches significantly contribute to an decrease in value of the information breached companies. The cross sectional regressions in this study estimate the significantly negative coefficient for the ME/BE variable, the proxy for a growth opportunity at the 5 % level. This suggests a reverse relation between the growth opportunity of companies and their value. As for the various samples of the information security companies categorized by physical security, network and system security, security application software, code authentication, system integration, we find the significantly positive AAR on the day after the event day at the 5% level, only for the network and system security-companies. This addresses that the information transfer effect followed by personal information breaches is uniquely observable for companies categorized into network and system companies. The regressions for the network and system companies estimate the significantly positive coefficient for the NS dummy variable (i.e., the dummy of the network and system security companies) at the standard level. This allows us to identify appropriate times needed to make the information transfer effect realized from personal information breached companies to information security companies.

In Korea, Private security companies has steadily grown and amounts to 2,051 places as of November 30, 2002. Private security in korea is carrying out firm name role assignment to have held the police and public peace environment change factors for a standard faithfully, and protects social a little property that is a basic purpose, and it is spare no efforts in loss prevention. In spite of numeral increase of private security companies, private security companies have many problem. Moreover, they mostly did not have any remarkable in-house expertises in their own business under tough conditions. Under the unfavorable circumstances including insufficient investment and education in private security guard, there have been actually little further studies on private security business in practices. So this study mainly focused on addressing the installation security business managed by authorized companies, which amount to 96%(1,963 companies) of total 2,051 domestic security companies. Furthermore, the study formulated and modeled a series of business procedures in private security companies. A series of business procedures of private security companies can be modeled as follows : Setting of a business scope and aim market ${\Rightarrow}$ Marketing, Contact from customers(On-line or Off-line) ${\Rightarrow}$ Diagnosis of security target ${\Rightarrow}$ Submission of security operational plan ${\Rightarrow}$ Estimation of security operational plan ${\cdot}$ decision ${\Rightarrow}$ Contract ${\Rightarrow}$ Employment, selection of security guards ${\Rightarrow}$ Nomination of security guard instructors ${\Rightarrow}$ Education & training of security guards ${\Rightarrow}$ subscribe to insurance of damage liability ${\Rightarrow}$ Commitment and placement of security guards ${\Rightarrow}$ Establishment and preparation of security planning ${\Rightarrow}$ Field management and procurement of relevant security service.

이 연구의 목적은 신정보화환경에서의 중소기업의 기술유출에 대한 보안인식 및 보안관리 실태를 측정하고, 대기업과 중소기업간의 수준비교분석을 통해 기술유출 방지대책을 위한 정책의 기초자료를 제시하고자 한다. 분석결과 보안인식 및 보안관리실태 모두 중소기업은 대기업에 비해 열악한 것으로 나타났으며, 정보화환경의 급격한 발달에 따른 부문별 관리가 필요한 상황인 것으로 보인다. 현재 중소기업의 신정보화환경 구축은 도입기에 있으므로, 구축과 동시에 보안시스템을 함께 갖출 수 있는 지원이 필요하며, 동시에 중소기업 자체적 대응이 가능하도록 신정보화환경에 맞는 보안시스템이 필요하다. 중소기업의 경우 급변하는 정보화환경의 변화에 따른 기술보호 역량을 갖추기에는 한계가 있음으로 정부의 체계적인 보안관리 지원이 요구된다.

현재 우리나라의 인터넷과 IT 인프라는 세계 최고 수준을 유지하고 있다. 그러나 그 이면에는 보안사고, 특히 개인정보 유출 사고가 빈번히 발생하고 있다. 개인정보 유출 사고 발생 시 해당 기업은 부정적 영향을 받게 되며, 이를 방지하기 위해 정보보호 업체의 다양한 보안 솔루션을 사용하고 있다. 따라서 개인정보 유출 사고 발생 시 발생 기업은 물론 기업에 보안 솔루션을 제공하는 정보보호 업체에도 영향을 미칠 것으로 생각된다. 이에 본 논문에서는 개인정보 유출 사고 발생 시 정보보호 업체의 주가 변화를 통해 보안 이벤트가 정보보호 업체의 가치에 어떠한 영향을 주는지 가설을 세워 검증하였다. 그 결과 개인정보 유출 사고 발생 시 정보보호 업체의 주가는 상승하였으며, 사고 규모, 사고 발생 업종에 따른 차이는 통계적으로 유의하지 않았고, 정보보호 업체의 업태 구분에 따른 차이가 존재하였다.

The purpose of this study is to examine the operational performances by the investment level of information security in companies. The theoretical background summarized the meaning of information security, management information security, and network security. The research process was carried out in four stages. As a result of the analysis, the level of information security was classified into four groups, and the difference in operational performance was confirmed. According to the categorical regression analysis of the three dependent variables, independent variables such as network threats, non-network threats, executive information security awareness, industry, organizational size, and information security education all affected information security regulations, in-house information security checks, and information security budget investments. The theoretical implications of this study have contributed to updating the latest information security theory. Practical implications are that rational investments should be made on the level of information security of companies.

최근 지속적으로 발생하는 보안위협은 기업의 비즈니스 연속성을 저해할 뿐만 아니라 사회적 국가적 차원에서도 그 심각성이 높아지고 있는 실정이다. 이러한 보안위협은 기업과 국가 간 경쟁력이 심화 되면서 기업의 지적 재산권 침해가 지속적으로 증가함에 따라, 기업들은 다양한 IT 컴플라이언스(compliance) 법제들에 대하여 의무적 준수와 더불어 엄격한 법적 책임을 부담하여야 한다. 따라서 본 연구에서는 기업의 능동적인 IT 컴플라이언스 활용을 위해 머신러닝(machine learning) 기술을 이용한 융합보안 컴플라이언스 관리 모델을 제안하고자 한다.

The majority of financial and general business organizations have had individual damage from hacking, worms, viruses, cyber attacks, internet fraud, technology and information leaks due to criminal damage. Therefore privacy has become an important issue in the community. This paper examines various elements of the information security management system and discuss about Information Security Management System Models by using the analysis of the financial statue and its level of information security assessment. These analyses were based on the Information Security Management System (ISMS) of Korea Information Security Agency, British's ISO27001, GMITS, ISO/IEC 17799/2005, and COBIT's information security architecture. This model will allow users to manage and secure information safely. Therefore, it is recommended for companies to use the security management plan to improve the companies' financial and information security and to prevent from any risk of exposing the companies' information.
