This study is the research of enterprise security for raising the profitability and stability of Korean companies in global business environment and strategic cooperation of business. As the scientific technology gets complicated as day goes by and new competitors appear regardless the border in the modern business environment, the situation happens frequently which the huge company hands over their market to the new one armed with the innovative thinking overnight. To survive such new environment, the answer is the change of paradigm regarding business management method at the new point of view. With the low level of security risk management of Korean companies which stick to old habit, the security management which helps the companies secure profits is not affordable. The global village where the population of 7 billions live in 21st century is facing up to the rapid ecological adaptation. The rapid change of climatic environment creates the hundreds of thousands of sufferers in a moment, and we have been watching the millions of livestock are buried alive due to new contagious disease everyday. Such change encourages the humans in global village to change the basic way of living. The business ecosystem which is the basic root for economic life cannot be an exception. To survive the business environment of 21st century, the security risk management at management level is required and the reporting line of companies should be established newly for raising business competing power through security risk management. The companies should bear in mind that they can be disappeared into our old memories overnight if they are not sensitive to the changing environment. Out of new risks for the modern companies, the field especially Korean companies are dealing easily is the security risk. Not like past, the security risk which's size is much more massive and its propagation velocity is very fast is the one of important business risks which the management should take care. Out of security risks which influence on the modern companies significantly, the brand of companies, protection of their reputation, continuity of production and operation and keeping customer's trust are prior to the others. This study offered the suggestion regarding enterprise security and the strategic cooperation of business to deal with such security risk effectively.

개인정보보호 유출사고가 줄지어 법정으로 향하고 있다. 내외부자에 의한 고객정보의 불법 유출이 그 원인으로, 굵직굵직한 소송사건들이 과연 어떤 판례를 남기게 될 지가 많은 기업들에게 초미의 관심사가 되고 있다. 개인정보를 대량으로 수집하는 기업들이라면 이런 법정 공방은 '내' 문제가 될 수 있기 때문이다. 이와 같은 기업의 관심은 자연스럽게 데이터베이스 즉, DB 보안에 대한 관심으로 이어지고 있다.

Corporation's computerization developed by diffusion of internet, and dysfunction of Information is increasing greatly with virus, computing network infringement. Therefore, the today, corporation security is more and more emphasized. Security solution by that importance of security rises so is developing together Security solution is developing to ESM system in existing single system and important thing is function of each security solution and optimizing design of policy. Existent security policy taking a serious view security from external invasion but security of interior the importance rise the today. Accordingly, must construct ESM system of new structure for this. This paper proposes and embodied integration security administration system that solidify interior security utilizing IDS. Experiment external IP and ID access and analyzed the result.

최근 정보기술의 발달로 해킹 등 각종 보안위협이 증가하고 있으며 이는 기업 경영에 심각한 위협으로 다가오고 있다. 해킹을 당한 기업은 금전적인 손실과 더불어 기업 이미지에 심각한 타격을 입고 뒤늦게 정보보호의 중요성을 인식하여 보안 대책을 수립하고 있지만 주먹구구식 인 경우가 대부분이다. 본 논문에서는 기업의 중요자산과 정보시스템을 보호하기 위해 반드시 고려해야 할 보안관리 방안을 제시하고 SK텔레콤의 사례를 설명하려 한다.

20세기 이후 대한민국의 중소기업은 큰 성장률을 보인 반면, 정보보안의 중요성에 대한 인식은 크게 개선되지 않아 중소기업에서 이용하는 시스템에 많은 취약점이 존재한다. 이와 같은 취약점을 악용한 해커들의 다양한 자동화 공격 툴로 인해 보안 사고가 꾸준히 증가하는 추세이다. 그러나 중소기업의 특성 상 부족한 예산과 보안 인력의 부재로 실질적인 대응이 어려운 상황이다. 이 프로젝트는 이러한 예산 및 보안 인력의 부재에도 중소기업에서 사용 가능한 보안 솔루션 개발을 목적으로 한다.

In digital convergence environment, information security management plays crucial role in maintaining firms' competitiveness. Organizational citizenship behavior(OCB) enables informations security countermeasures to be more effectively worked by helping employees to have much knowledge of information security policy, by facilitating employees to participate in information security education/training. Thus, the purpose of this study is to investigate the mediating effect of OCB on the relationships between information security countermeasures and compliance intention. Questionary was designed based on prior information security research, and survey was conducted among companies' employees across the industry. Results showed that information security policy and information security education/training were found to be key predictors of compliance intention. In addition, OCB was proven to mediate the relationships between information security countermeasures and compliance intention.

An internal and external threat against an information system has increased, and to reduce it, organization has spent a great deal of money and manpower. However, in spite of such investment, security threat and trouble have happened continuously. Organization has conducted information security activity through various policies. The study classified such activities into prevention-oriented activity and control-oriented activity, and researched how information security activity of organization affects members of an organization and obeys information security policy by using health belief model. As a result of the study, prevention-oriented activity has a meaningful impact on seriousness, and this seriousness affects compliance intention for information security. Control-oriented activity has a meaningful impact on benefits, and the benefits have an effect on compliance intention. When an organization conducts prior activities such as education, PR, and monitoring, this organization should emphasize negative results that can happened because of deviation. In addition, in case of exposure and punishment through post activities such as inspection and punishment, if the organization emphasizes the positive effects of exposure and punishment rather than emphasis of negative parts, information security activity will be more effective.

최근 들어 보안에 대한 피해의 급증으로 많은 기업들이 정보시스템에 막대한 기업 자원을 투입하고 있다. 뿐만 아니라, 다양한 ROI 평가 방법을 통해 투자대비 최대 수익률을 이끌어 내기 위해 끊임없이 시도하고 있다. 이는 많은 기업들이 정보시스템에 대한 투자를 유보하거나 정확한 평가 및 방법을 내리고 싶어한다는 증거이다. 이러한 기업의 추세는 최근 보안 분야에 있어 합리적인 보안 투자 방침을 세우는데 좋은 지침이 되어 지고 있다. 그러나. 지금의 대규모 정보 시스템 구축 및 웹기반의 인프라 환경에서는 적절한 보안 투자를 한다는 것은 쉽지 않다. 이러한 근본적인 이유 중 하나는 수익률을 측정하는 방법의 부재에서 찾을 수 있다. 따라서, 본 논문에서는 보안 분야에서 쓰이는 기존의 ROSI(Return On Security Investment)모델을 소개하고, 투자의 위험부담을 줄이기 위한 확률 기반의 개선된 ROSI(Probability based ROSI = PROSI) 방법론을 제안하고자 한다.

예전 기업 그룹웨어 환경은 기업 소유의 기기을 활용하는 사내에 출근한 직원들 대상으로만 서비스 하였다. 그러나, 스마트폰 보급이 확대되면서 사외에서 기업내부로 접근하여 그룹웨어 등을 활용할 수 있는 스마트워크 서비스가 발전하였다. 또한 사내로 반입된 개인 소유 단말 기기가 그룹웨어 서비스를 접속할 수 있는 BYOD 도입 기업들이 증가하고 있다. BYOD, 스마트워크 환경에서 기기 접속 위치, 시간 등 다양한 접속 상황을 활용한 보안정책 관리 구조를 연구하였다. 본 논문에서는 서비스 접속 이후 보안에 취약한 서비스 접근 상황정보 중심 보안정책의 한계를 개선하기 위하여 서비스 웹/DB 서비스 이용 상황정보 기반 보안정책 구조를 제안한다.

STI(Social Trust Index) indicates levels of trustworthiness, honesty and reliability among people in a society. Since the STI varies in countries, security control on cyber space should be applied differently according to the STI so that companies can protect their assets efficiently and effectively. We compare STIs between Korea and United States using the Diamond Model and investigate how the STIs affect corporate security controls in those two countries. We finally present a formula using AHP (Analytic Hierarchy Process) to measure levels of corporate security controls in different countries.
