Instrumentation and control systems in nuclear power plants have been digitalized for the purpose of maintenance and precise operation. This digitalization, however, brings out issues related to cyber security. In the most recent past, international standard organizations, regulatory institutes, and research institutes have performed a number of studies addressing these systems cyber security.. In order to provide information helpful to the system designers in their application of cyber security for the systems, this paper presents methods and considerations to define attack vectors in a target system, to review and select the requirements in the Regulatory Guide 5.71, and to integrate the results to identify applicable technical security control requirements. In this study, attack vectors are analyzed through the vulnerability analyses and penetration tests with a simplified safety system, and the elements of critical digital assets acting as attack vectors are identified. Among the security control requirements listed in Appendices B and C to Regulatory Guide 5.71, those that should be implemented into the systems are selected and classified in groups of technical security control requirements using the results of the attack vector analysis. For the attack vector elements of critical digital assets, all the technical security control requirements are evaluated to determine whether they are applicable and effective, and considerations in this evaluation are also discussed. The technical security control requirements in three important categories of access control, monitoring and logging, and encryption are derived and grouped according to the elements of attack vectors as results for the sample safety system.

The Incoterms(R) 2010 rules take account of the continued spread of customs-free zones, the increased use of electronic communications in business transactions, heightened concern about security in the movement of goods and changes in transport practices. And the Guide to Incoterms(R) 2010 is the authoritative companion work to Incoterms(R) 2010, the ICC rules on the use of domestic and international trade terms. The guide responds to business needs for a better understanding of these ICC rules that are used in countless commercial transactions every day. But, contrary to the previous guidebook, there is many errors and mistake in the Guide to Incoterms(R) 2010 which should be amended. The purpose of this paper is to point out the problems and amend the errors and unify the expression in guidebook.

The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the re suiting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or sys tems they will buy and operate. In this paper, we propose a selection guide for If products by show ing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.

This paper discusses an issue of serious security risks at web log which contains private information, and suggests solutions to protect them. These days privacy is core information to produce value-added in information society. Its scope and type is expanded and is more important along with the growth of information society. Web log is a privacy information file enacted as law in South Korea. Web log is not protected properly in spite of that has private information It just is treated as residual product of web services. Many malicious people could gain private information in web log. This problem is occurred by no classified data and improper development of web application. This paper suggests the technical solutions which control data in development phase and minimizes that the private information stored in web log, and applies in operation environment. It is very efficient method to protect private information and to observe the law.

Mobile Agent has been known that it is an efficient communication paradigm for distributed applications and that a mobile agent provides higher flexibility and performance than existing communication paradigms. Despite these benefits, mobile agent is not used widely in the market because it is very vulnerable to a variety of attacks. To be applied to develop distributed applications, a mobile agent paradigm must consider both security and performance. In this paper, we propose and evaluate an improving method of a migration performance for a mobile agent model using ISM(Integrated Security Manager), which provides high-level security services and travel plan guide. In the proposed method. ISM offers the travel plan guide service which replies the accumulated results when a mobile agent has executed all migration plans related the trusted domain to be managed by ISM. Our method improved about $33{\sim}82%$ of total execution time than the existing method.

The purpose of this thesis is to research and propose a practical Information Security Technical Architecture on Primary Defense Information Infrastructure with regard to requirement of information security. The scope of this research is limited to national defense information master plan & security rule, and U.S. DoD's IATF is used to plan a detailed structure. The result of this research can be used as a guide book for providing security for Army IT infrastructure now and in the future as well as to devise a plan for research and development in information protection technology.

This paper analyzed factors for employees to violate information security policy in financial companies based on the theory of reasoned action (TRA), general deterrence theory (GDT), and information security awareness and moderating effects of perceived sensitivity of customer information. Using the 376 samples that were collected through both online and offline surveys, statistical tests were performed. We found that the perceived severity of sanction and information security policy support to information policy violation attitude and subjective norm but the perceived certainty of sanction and general information security awareness support to only subjective norm. Also, the moderating effects of perceived sensitivity of customer information against information policy violation attitude and subjective norm were supported. Academic implications of this study are expected to be the basis for future research on information security policy violations of financial companies; Employees' perceived sanctions and information security policy awareness have an impact on the subjective norm significantly. Practical implications are that it can provide a guide to establish information security management strategies for information security compliance; when implementing information security awareness training for employees to deter violations by emphasizing the sensitivity of customer information, a company should make their employees recognize that the customer information is very sensitive data.
