Recently, enterprises have reinforced security control in order to prevent infringement of personal information and abuse of customer information by insiders. However, the reinforcement of security control by enterprises makes it difficult for internal users to perform business by using a business information system. There is, therefore, a need for research on various fields, which makes it possible to establish an appropriate security control policy while minimizing an impact on business. The present research verifies and analyzes an impact on difficulty in business of internal users using customer information, which is caused by security control performed by display restriction on customer information identifiers. The present research is intended to academically develop a technique for statistically analyzing an impact degree and a causal relationship between security control and an impact on business, which is a dichotomous variable, and to practically contribute to the establishment of an efficient security policy in consideration of an impact on business when an enterprise applies security control. A research target was internal business information systems of domestic securities enterprises, data was collected by questionnaire, and verification/analysis was performed by logistic regression analysis.

Depending on the sophistication of IT, it is increasing more and more information leaks and breaches. Accordingly the majority of companies have expand investment protection for the information. However, companies still have been exposed the vulnerability of information leakage. Especially, small IT service businesses than large corporations relatively have some limitations in the points of resources and manpower business activities. For studies on information security for small IT service companies so far, however, there have been insufficient studies considering small business scales and business characteristics of IT services. In this study, we made to design an information security management model for establishing security measures of small IT service companies which are classified SI/SM, DB, IR and IP industry that depending on how the value creation of the business. In detail, we performed an empirical analysis for small IT service business to consider business characteristics and we proposed security implementation strategies based on the analysis results.

To establish an effective security strategy, business enterprises need a security benchmarking tool. The strategy helps to lessen an impact and a damage in any threat. This study analyses many aspects of information security management and suggests a way to deal with security investments by considering important factors that affect security manager's decision. To address the different threats resulting from a major cause of accidents inside an enterprise, we investigate an approach that followed ISO17799. We unfold a criminology theory that has designated many measures against the threat as suggested by General Deterrence Theory. The study proposes a coherent model of the theory to improve the security measures especially in handling and protecting company assets and human lives as well.

This study introduces server-side security-oriented framework for smart financial service. Most of domestic financial institutions providing e-banking services have employed server-side framework which implement service-oriented architecture. Because such architecture accommodates business and security requirements at the same time, institutions are struggling to cope with the security incidents efficiently. The thesis suggests that separating security areas from business areas in the frameworks makes users to be able to apply security policies in real time without considering how these policies may affect business transactions. Security-oriented frameworks support rapid and effective countermeasures against security threats. Furthermore, plans to avoid significant changes on existing system when institutions implement these frameworks are discussed in the report.

Information security management systems (ISMSs) are used to manage information about their customers and themselves by governments or business organizations following advances in e-commerce, open networks, mobile networks, and Internet banking. This paper explains the existing ISMSs and presents a comparative analysis. The discussion deals with different types of ISMSs. We addressed issues within the existing ISMSs via analysis. Based on these analyses, then we proposes the development of an information security management evaluation system (ISMES). The method can be applied by a self-evaluation of the organization and an evaluation of the organization by the evaluation committee. The contribution of this study enables an organization to refer to and improve its information security levels. The case study can also provide a business organization with an easy method to build ISMS and the reduce cost of information security evaluation.

This paper formally defines a role-driven security and access control model of a business process in order eventually to provide a theoretical basis for realizing the secured business process management systems. That is, we propose a graphical representation and formal description of the mechanism that generates a set of role-driven security and access control models from a business process modeled by the information control net(ICN) modeling methodology that is a typical business process modeling approach for defining and specifying business processes. Based upon the mechanism, we are able to design and accomplish a secured business process management system that provides an unified resource access control mechanism of the business process management engine domain's and the application domain's. Finally, we strongly believe that the secured access control policies from the role-driven security and access control model can be easily transformed into the RBAC(Role-based Access Control) model that is a standardized security technology for computer and communications systems of commercial and civilian government organizations.

Our approach permits to capitalize the expert's knowledge as business rules by using an agent-based platform. The objective of our approach is to allow experts to manage the daily evolutions of business domains without having to use a technician, and to allow them to be implied, and to participate in the development of the application to accomplish the daily tasks of their work. Therefore, the manipulation of an expert's knowledge generates the need for information security and other associated technologies. The notion of cryptography has emerged as a basic concept in business rules modeling. The purpose of this paper is to present a cryptographic algorithm based approach to integrate the security aspect in business rules modeling. We propose integrating an agent-based approach in the framework. This solution utilizes a security agent with domain ontology. This agent applies an encryption/decryption algorithm to allow for the confidentiality, authenticity, and integrity of the most important rules. To increase the security of these rules, we used hybrid cryptography in order to take advantage of symmetric and asymmetric algorithms. We performed some experiments to find the best encryption algorithm, which provides improvement in terms of response time, space memory, and security.

Recently, Financial companies implement DLP(Data Leaks Prevention) security products and enforce internal controls to prevent customer information leaks. Accidental data leaks in financial business increase more and more because internal controls are insufficient. Security officials and IT operation staffs struggle to plan countermeasures to respond to all kinds of accidental data leaks. It is difficult to prevent data leaks and to control information flow in business without research applications that handle business and privacy information. Therefore this paper describes business and privacy information flow on applications and how to plan and deploy security container based OS-level and Hypervisor virtualization technology to enforce internal controls for applications. After building security container, it was verified to implement internal controls and to prevent customer information leaks. With security policies additional security functions was implemented in security container and With recycling security container costs and time of response to security vulnerabilities was reduced.

The importance of information security is increasing, and various efforts are being made to improve users' information security behaviors. Among these various efforts, information security education is mainly aimed at providing users with information security knowledge and improving information security awareness. This study classified the types of information security education into offline and online to examine the effects of each education method on attitudes toward information security (perceived severity, vulnerability, self-efficacy and response-efficacy) and information security behaviors. A survey was conducted for users with information security education experiences. The results obtained by comparing the differences in the path coefficients of personal information security behaviors according to information security education experiences showed that security behaviors were more significant in the online experience group than the offline group. In addition, gender differences were analyzed, and it was found that females had a greater impact on information security attitudes than males. This study also found that among Internet users with online information security education experience, females tend to have more information security behavior than males, but there were contrasting results among users with offline information security education experiences. The results of this study finally address the necessity of reflecting users' personalities in the systematic design of information security education in the future. Furthermore, the results of this study support the need for an appropriate education system that sufficiently understands education types to maximize the effects of information security education.
