The mobile payment app market has been expanding recently. However, the usage rate of mobile payment apps is not meeting service providers' expectations due to concerns about security and privacy. This study investigated how personal predisposition and how the security signals of the payment app affect users' perceived privacy and security risks, and how these factors ultimately affect the trust of mobile payment apps. The results showed that privacy concerns increase the risk of perceived personal information leaks and reduce perceived mobile system security, while familiarity, perceived reputation, and assurance seal reduce the risk of perceived personal information leaks and increase perceived mobile system security. Finally, it revealed that the reduced risk of perceived personal information leaks and the increased security of mobile systems had a positive impact on the reliability of mobile payment apps.

본 기고는 기업에서 지난 6년 동안 정보보호 관련업무 실무책임자로서의 경험을 토대로 어떻게 하면 보다 더 효율적이고 안정적인 정보보호활동을 수행할 수 있을까 하는 관점에서 바람직한 CSO의 역할 모델을 정리해 본 글이다. 전혀 보안에 신경을 쓰지 않아도 보안사고가 발생하지 않으면 100점짜리 보안수준이 되는 것이고, 제아무리 보안교육과 점검을 실시하고 취약점을 개선하기 위한 다양한 보안투자를 시행하더라도 보안사고가 터지는 순간, 보안수준은 순식간에 빵점짜리로 전락한다. 때문에 필자는 종종 정보보호 책임자는 안전고리를 벗겨낸 폭탄을 가슴에 품고 언제 터질지 모르는 지뢰밭에 서있는 사람이라고 역설한 바 있다. 최근 급속한 IT기술의 발전과 극심한 개인주의 성향 등으로 그 어느 때보다 보안사고의 위험성과 피해규모가 크게 증대되고 있으며, 이에 따라 기업에서 정보보호 업무 수행부서의 역할과 책임범위 역시 과거와 달리 매우 광범위하게 확장되고 있는 실정이다. 특히 우리나라는 90년대 말 IMF 당시 구조조정의 여파로 중국을 비롯한 해외 경쟁회사로 국내 기술자들이 이직함으로써 핵심 산업기술의 유출이라는 피해를 경험한 바 있다. 그런데 최근 미국에서 시작된 세계경기의 위축으로 또 한 차례의 보안사고 위험성에 크게 노출되어 있는 상황이다. 각 국의 문화 및 산업의 다양성만큼이나 수많은 위험성이 산재하고 있는 현대 사회에서 바람직한 CSO가 되기 위한 몇 가지 착안사항들에 대하여 논해 보고자 한다.

공공기관은 자신의 정보시스템에 대한 보안 대책을 수립하기 위하여 자체 보안·분석평가를 수행함으로써 적절한 보안 목표와 방향을 설정해야 한다. 하지만, 현재 연구되어 있는 위험분석 및 보안평가방법론등은 복잡하고 전문적인 사항이 많으므로 자체 보안분석을 수행하기에는 인력 및 비용이 많이 소요된다. 이를 위하여 본 논문에서는 정보시스템의 위험분석방법론에서 제시하는 자산, 취약점, 위협, 대응책에 보안평가방법론을 포함하여 정보시스템에 대한 모델링, 가정, 증상, 원인, 해결책등을 통한 자가진단 보안 분석·평가 방법을 제시한다.

A security risk analysis provides all information system with the capability to investigate and estimate the status of its security, and gives a guideline for establishing a safeguard against any means of security threats. The information system needs tile judicious and accurate why for performing a risk analysis since security policy and risk analysis of tile information system are based on risk analysis, The risk analysis is composed of two methods. mathematical approach and diagramming technique. Mathematical approach cannot yield a precise description of the real world. However, diagramming technique is more pragmatic since it overcomes this limitation. In this paper, we studied tile security risk analysis methods proposed in overseas such as INFOSEC [4], SRAG [5], FIPS65[6], and JRAM[7].

Information security has been a major concern in organizations. The longstanding question of how to improve employees security behaviors and reduce human errors remains unanswered and requires further exploration in the information security domain. To do this, we propose a risk compensation theory-based model and examine the model. Research results shows that the relationships between information security countermeasures and information security compliance intention of employees are moderated by system vulnerability. However, the finding is contrary to the previously held risk compensation assumption and deserve further study. In addition, system quality does not play a moderator role in the relationship. Conclusions and implications are discussed.

Information society is dramatically developing in the various areas of finance, trade, medical service, energy, and education using information system. Evaluation for risk analysis should be done before security management for information system and security risk analysis is the best method to safely prevent it from occurrence, solving weaknesses of information security service. In this paper, Modeling it did the evaluation-base CBD function it will be able to establish the evaluation plan of optimum. Evaluation-based CBD(case-based reasoning) functions manages a security risk analysis evaluation at project unit. it evaluate the evaluation instance for beginning of history degree of existing. It seeks the evaluation instance which is similar and Result security risk analysis evaluation of optimum about under using planning.

Risk of damage on information system being grow according to increasing its dependence rate on most of organization. On this work, make planed for a safety assessment system in which information protection management system and threat analyzing method. Also, during threat assesment, we have planned possible an equal-weight applied assesment and considering the characteristics of the organization, an assesment which security factor's weight is variably applied to, and respective organizations to examine its security by itself in order to support the easy findings of the vulnerabilities on the management point of view, and to show the advices to practice.

As information and information technology become more important in competitive corporate environments, the risk of information security breaches has increased accordingly. Although organizations establish security measures to manage information security risks, members of organizations do not comply with them well, and their information security behavior intention is unclear. Therefore, to understand the information security risk management intention of the members of organizations, the present study developed a research model using Protection Motivation Theory, Supervisory Authority Pressure, and Background factors. This study presents empirical research findings based on the analysis of survey data from 201 members of financial institutions. Perceived Severity, Self-efficacy, and Supervisory Authority Pressure had a positive effect on intention; however, Perceived Vulnerability and Response Efficacy did not affect intention. Security Avoidance Habit, which was considered a background factor, had a negative effect on all parameters, and did not have an effect on intention. Security Awareness Training, another background factor, had a positive effect on information security risk management intention and perceived vulnerability, self-efficacy, response efficacy, and supervisory authority pressure, and had no effect on perceived severity. This study used supervisory authority pressure and background factors in the field of information security, and provided a basis to use supervisory authority pressure in future studies on behavior of organizations and members of an organization. In addition, the use of various background factors presented the groundwork for the expansion of protection motivation theory. Furthermore, practitioners can use the study findings as a foundation for organization's security activities, and to improve regulations.
