This paper explores how to characterise security properties of software components, and how to reason about their suitability for a trustworthy compositional contract. Our framework provides an explicit opportunity for software composers as well as software components to test a priori security properties of software components in a system composition. The proposed framework uses logic programming as a tool to represent security properties of atomic components and reason about their compositional matching with other components.

네트워크 로봇은 기존의 독립 로봇을 네트워크를 연결함으로써 서버와의 통신을 통해 언제 어디서나 다양한 서비스를 제공할 수 있다. 이러한 네트워크 로봇은 기존의 유 무선 네트워크 기술을 그대로 사용하여 실시간 서비스를 제공할 수 있다는 장점이 있지만 네트워크 보안 취약점으로 인하여 보안 취약점 문제가 발생할 수 있다. 그러므로 네트워크 로봇 환경에서는 다양한 통신 매체나 프로토콜에 관계없이 보안 기능을 만족할 수 있는 인증 프레임워크가 정립되어야만 한다. 본 논문에서는 네트워크 로봇 환경에서 발생할 수 있는 보안 취약점을 분석하고 이에 대한 대응방안을 정립한 후, 네트워크 로봇 환경에 적용할 수 있는 인증 프레임워크를 살펴보았다.

Compared to the past infrastructure networks, the current smart grid network can improve productivity and management efficiency. However, as the Industrial Internet of Things (IIoT) and Internet-based standard communication protocol is used, external network contacts are created, which is accompanied by security vulnerabilities from various perspectives. Accordingly, it is necessary to develop an appropriate cybersecurity guideline that enables effective reactions to cybersecurity threats caused by the abuse of such defects. Unfortunately, it is not easy for each organization to develop an adequate cybersecurity guideline. Thus, the cybersecurity checklist proposed by a government organization is used. The checklist does not fully reflect the characteristics of each infrastructure network. In this study, we proposed a cybersecurity framework that reflects the characteristics of a microgrid network in the IIoT environment, and performed an analysis to validate the proposed framework.

The global trading system is vulnerable to terrorist exploitation while the international trade is an essential element for the economic development. Customs has a unique role in the international trade to provide increased security while ensuring facilitation of the legitimate flow of goods and the role of Customs has become more and more indispensable these days. In response to this trend, the World Customs Organization(WCO), the organization of more than 170 Customs administrations all over the world, adopted an international framework("SAFE Framework") in 2005, which includes the Authorized Economic Operator(AEO) concept, whereby a party involved in the international movement of goods would be approved by Customs as complying with the supply chain security standards, and given benefits, such as simplified Customs procedure and less Customs intervention. In this stream, the Japanese government has developed and promoted AEO Program in close cooperation with the business sector, aiming at ensuring security while facilitating legitimate trade. For that purpose, Japan Customs, as a main entity in the field of international trade, has developed comprehensive AEO program with combination of programs for importers, exporters, warehouse operators, Customs brokers and logistics operators, such as forwarders and carriers, which are consistent with the "SAFE Framework" developed by the WCO. The purpose of this paper aims to analyse the introduction plans of AEO program for the trade security and trade facilitation with Japanese AEO system.

In this paper we applied our previously developed assessment framework to the data collected from an internet security readiness survey targeted at households. We used the assessment framework to compute an Internet Security Readiness index for each household, which was in turn derived from Internet Security Readiness capital, skill, and actual uptake/use of infrastructure indices. We then examined the relationships among overall Internet Security Readiness, and the capital, skill, and actual uptake/use of infrastructure related to Internet Security Readiness. In addition, we explored the influence of Internet usage level and experience on Internet Security Readiness.

The protection of nuclear safety software is essential in that a failure can result in significant economic loss and physical damage to the public. However, software security has often been ignored in nuclear safety software development. To enforce security considerations, nuclear regulator commission recently issued and revised the security regulations for nuclear computer-based systems. It is a great challenge for nuclear developers to comply with the security requirements. However, there is still no clear software development process regarding security activities. This paper proposes an integrated development process suitable for the secure development requirements and system security requirements described by various regulatory bodies. It provides a three-stage framework with eight security activities as the software development process. Detailed descriptions are useful for software developers and licensees to understand the regulatory requirements and to establish a detailed activity plan for software design and engineering.

Rapid progress of information technology and widespread use of the personal computers have brought various conveniences in our life. But this also provoked a series of problems such as hacking, malicious programs, illegal exposure of personal information etc. Information security threats are becoming more and more serious due to enhanced connectivity of information systems. Nevertheless, users are not much aware of the severity of the problems. Using appropriate password is supposed to bring out security effects such as preventing misuses and banning illegal users. The purpose of this research is to empirically analyze a research model which includes a series of factors influencing the effectiveness of passwords. The research model incorporates the concept of risk based on information systems risk analysis framework as the core element affecting the selection of passwords by users. The perceived risk is a main factor that influences user's attitude on password security, security awareness, and intention of security behavior. To validate the research model this study relied on questionnaire survey targeted on evening class MBA students. The data was analyzed by AMOS 7.0 which is one of popular tools based on covariance-based structural equation modeling. According to the results of this study, while threat is not related to the risk, information assets and vulnerability are related to the user's awareness of risk. The relationships between the risk, users security awareness, password selection and security effectiveness are all significant. Password exposure may lead to intrusion by hackers, data exposure and destruction. The insignificant relationship between security threat and perceived risk can be explained by user's indetermination of risk exposed due to weak passwords. In other words, information systems users do not consider password exposure as a severe security threat as well as indirect loss caused by inappropriate password. Another plausible explanation is that severity of threat perceived by users may be influenced by individual difference of risk propensity. This study confirms that security vulnerability is positively related to security risk which in turn increases risk of information loss. As the security risk increases so does user's security awareness. Security policies also have positive impact on security awareness. Higher security awareness leads to selection of safer passwords. If users are aware of responsibility of security problems and how to respond to password exposure and to solve security problems of computers, users choose better passwords. All these antecedents influence the effectiveness of passwords. Several implications can be derived from this study. First, this study empirically investigated the effect of user's security awareness on security effectiveness from a point of view based on good password selection practice. Second, information security risk analysis framework is used as a core element of the research model in this study. Risk analysis framework has been used very widely in practice, but very few studies incorporated the framework in the research model and empirically investigated. Third, the research model proposed in this study also focuses on impact of security awareness of information systems users on effectiveness of password from cognitive aspect of information systems users.
