In the past, organizations tended to focus on physical and technical aspects of managing corporate's information security (IS), rather than the aspect of human resources related to IS. Recently, increasing security incidents caused by organization members raise the issue of how to improve employees' compliance with security policies. This study conducted a field experiment to examine the effect of security awareness training and technical security services on employee's security behaviors. In Study 1, the number of spam opening cases were measured right after the IS training and re-measured three months later. In Study 2, a spam warning message was provided and then the number of employees' spam opening cases were counted to find out the effect of security services. It was found that both the IS training and the technical IS service were effective; they significantly decreased spam opening rates. However, the training effect did not last longer than three months. These findings suggest that organizations need to consider providing regular training programs and supplementary technical services to improve employees' compliance with security policies.

Elementary school students have a little awareness of privacy protection since they do not have many opportunities for systematic education on information and communication ethics. Hence, they are likely to expose their own information to others and sometimes bring on a lot of misuses by using others' information. In this paper, we provide an idea for teaching and learning methods which the elementary school students acquire privacy protection and management methods and raise their practical capabilities. We develop a role play teaching and learning model in connection with various Information and Communication Technology (ICT) activities and establish the instruction plans. Moreover, we apply them to the actual classes at grade five and six of the elementary school students respectively, and finally analyze the results. The proposed teaching and learning method shows that the students participated in a series of learning activities have higher learning effects on awareness of privacy protection than those learned with the conventional methods.

Today many companies introduce new mobile office environments evolved from the recent rapid development in mobile device technologies. Most of the recent mobile office systems use a simple authentication scheme such as ID/Password. This method is easy to use, but it does not consider the user's context. Thus it cannot provide appropriate security service required by the user's proper contexts. Therefore, this paper proposes a context based authentication system which applies security level verification and uses fuzzy algorithm based on the importance of access authority control.

Many security issues occur in cloud computing service environment such as authentication, access control, and so on. In this paper, we propose an effective authentication and access control model which provide integrated management and control when we access various resources in cloud computing environment. To address these problems, we suggest a context-aware single sign-on and access control system using context-awareness, integrated authentication, access control, and OSGi service platform in cloud computing environment. And we show design and implementation of context-aware single sign-on and access control system. Also we verified the flexibility and convenience of the proposed system through multi fact based integrated authentication in cloud computing environment. We could provide flexible and secure seamless security service by user context in cloud computing environment.

This study focused on how to supplement and develop military spiritual education in response to promotion of peace and prosperity and Change of Security Environment on the Korean Peninsula. In order to succeed in the peace and prosperity on the Korean Peninsula policy, Strengthening the military spiritual education is necessary. This study was analyzed through the survey and the results are as follows: First, the awareness level of military spiritual education is more than 68%. Second, the satisfaction level of education has been quit motivated, but, the respondents demands various methods of eduction. Third, the current mental power scores showed no significant difference for environmental change. In addition, based on the results of the research, the problem of military spiritual education is as follows. It is not enough to secure the identity that can firmly support the era of peace and prosperity on the Korean peninsula. Poor budget support might hinder improving poor education facilities and outdated equipment. Furthermore, there is a lack of research on future-oriented educational system in support of traditional education methods of repetition-type repeated education and unification. Therefore, we deducted the following development strategies for the military spiritual education in this paper. First, it is necessary to strengthen the military spiritual education to support the era of peace and prosperity on the Korean Peninsula. Second, for enhancing educational environments, the educational facilities and equipments should be improved by understanding the characteristics of the education target. Third, the integrated management of military research institutes specialized in military spiritual education should be pursued as a system development for ensuring the continuous effect of education. In conclusion, continuous attention and research are needed to establish national perspective and national security perspective, raise the military spirit and utilize various education development programs in order to develop efficient military spiritual education in the future.

The initial research of Task Computing in the ubiquitous computing (UbiComp) environment revealed the need for access control of services. Context-awareness of service requests in ubiquitous computing necessitates a well-designed model to enable effective and adaptive invocation. However, nowadays little work is being undertaken on service access control under the UbiComp environment, which makes the exposed service suffer from the problem of ill-use. One of the research focuses is how to handle the access to the resources over the network. Policy-Based Access Control is an access control method. It adopts a security policy to evaluate requests for resources but has a light-weight combination of the resources. Motivated by the problem above, we propose a universal model and an algorithm to enhance service access control in UbiComp. We detail the architecture of the model and present the access control implementation.
