The threat to information security is growing globally. To this, organizations are increasing the weight of adapting and operating the more specialized information security policy and system. Information security requires participation from the employees who execute the security system and policy, and to increase the level of organization's internal security, requires organization's systematic support to improve employees' information security compliance intention. This research finds the mechanism for improving employee's information security compliance intention by applying justice theory and goal setting theory in information security. We use structural equation modeling to verify the research hypothesis, and conducted a survey on the employees of organization with information security policy. In other words, this research performs verification of the research model based hypothesis which claims that security policy goal setting has positive influence on employee's level of security related justice recognition, and claims that justice has positive influence on compliance intention. The object of study is the employees of the organization that adapts information security policy, and 383 valid samples were collected via survey. Structural equation modeling was performed to verify the research hypothesis. The result shows that security policy goal factor (goal difficulty, goal specificity) improves employee's security related justice recognition, and that security related justice (distribution, process, and information justice) has positive influence on compliance intention. The result suggests the strategic approach directions for improving employees' compliance intention on organization's security policy.

This study will propose the policy priorities of cyber information security by AHP(Analytic Hierarchy Process) survey. The policy categories for AHP survey consist in the foundation of information security and activity of information security(1st hierarchy). In the second hierarchy, the foundation of information security was classified into laws-system, human resources, h/w-s/w technology and sociocultural awareness. And the activity of information security was divided into infrastructure protection, privacy protection, related industry promotion, and national security. Information policy alternatives were composed of 16 categories in the third hierarchy. According to the AHP result, in the perspective of policy importance, the modification of related laws was the first agenda in the policy priority, better treatment of professionals was the second, and the re-establishment of policy system was the third. In the perspective of policy urgency, the re-establishment of policy system was the first item, the modification of related laws was the second, and better treatment of professionals is the third.

The ultimate aim of this study is to examine the effect of security policy characteristics (policy threat, policy effectiveness, policy compliance cost, policy compliance self-efficacy, social influence) on organizational information security policy compliance motivation based on TTAT (Technology Threat Avoidance Theory). We found the following results. First, the security policy threat has a significant positive effect on policy compliance motivation. Second, it was found that the policy effectiveness has a statistically significant effect on the compliance motivation. Third, the policy compliance cost has an influence on the policy compliance motivation. Fourth, the policy compliance self-efficacy does not have an effect on compliance motivation. Finally, social influence has a significant effect on compliance motivation.

Advances in information technology has brought many benefits to businesses, but at the same time, businesses are facing serious problems caused by its use such as information leakage. In order to cope with problems, companies have established information security policies, demanding workers of a company to be compliant with the policies. This study proposes a research model that includes information security awareness, information security attitude, self-efficacy, standard belief and social influences as factors that affect the compliance of information security policy among the workers of shipping and port organization. The results of this study showed that there was a positive relationship not only between the information security awareness and the information security attitude, but also between the information security attitude and the information security policy among the workers of shipping and port organization. It was also found that there was a positive relationship between the self-efficacy and the compliance of information security policy, and between the social influence and the compliance of information security policy. However, there was no meaningful relationship between the standard belief and the compliance of information security policy. This study examined to what extent the workers of shipping and port organization that have a high possibility of the information leakage were compliant with the information security policy. The findings will contribute to organizations of shipping and port who attempt to establish strategies related to information security.

OBS망에서 버스트의 충돌로 인한 버스트의 drop은 TCP의 성능에 중요한 영향을 끼치나, 기존의 drop policy에서는 이를 고려하지 않으며 TCP에 대한 연구로는 버스트의 assembling이 주를 이루고 있다. 본 논문에서는 OBS망에서 TCP의 재전송 문제를 drop policy와 연계하여 그 성능을 향상시키고자 한다. 본 논문에서 제안하는 drop policy는 버스트의 재전송 횟수가 더 작은 버스트를 drop시키는 TCP 기반 DP이다. TCP 기반 DP 모델과 일반적인 DP 모델의 성능을 ns­2를 이용한 시뮬레이션을 통해 평가하며, 이 때 시간의 변화에 따른 TCP throughput과 패킷의 drop rate을 비교 분석한다.

Personal health records (PHRs) is an electronic medical system that enables patients to acquire, manage and share their health data. Nevertheless, data confidentiality and user privacy in PHRs have not been handled completely. As a fine-grained access control over health data, ciphertext-policy attribute-based encryption (CP-ABE) has an ability to guarantee data confidentiality. However, existing CP-ABE solutions for PHRs are facing some new challenges in access control, such as policy privacy disclosure and dynamic policy update. In terms of addressing these problems, we propose a privacy protection and dynamic share system (PPADS) based on CP-ABE for PHRs, which supports full policy hiding and flexible access control. In the system, attribute information of access policy is fully hidden by attribute bloom filter. Moreover, data user produces a transforming key for the PHRs Cloud to change access policy dynamically. Furthermore, relied on security analysis, PPADS is selectively secure under standard model. Finally, the performance comparisons and simulation results demonstrate that PPADS is suitable for PHRs.

In the field of access control, policy conflicts must be solved and various related solutions are being researched and developed. In order to resolve the policy conflict problem, it is necessary to first identify the cause of the conflict, and as a minimum condition, it is necessary to detect the contextual elements of the policy that have influenced the policy evaluation decision. Although the XACML policy language specification provides a way to define this, the policy creator currently has limitations in not clearly describing the causes of conflicts in every contextual elements. In addition, in order to identify the causes of the policy conflict, it is necessary to acquire additional information such as other policy combination algorithms, in addition to these contextual factors. In this paper, we propose an effective method to identify contextual factors, as well as to locate additional information that cause policy conflicts.

As the Information and Communication Technology developed, the administration computerization of the government was promoted, and cyber attacks targeting IT products are spreading all over the world due to the reverse functions. Accordingly, governments in each country have begun to verify the security in the introduction of IT products by national and public institutions in order to protect information, and established the policy required in the introduction process. This research analyzes the introduction policy of domestic IT products to identify the supplement point. In addition, we analyze trends of introduction of IT products in the major developed countries such as USA, UK, Japan, Canada, and Australia. Finally, we propose the improvement method of domestic introduction policy through comparison analysis with domestic introduction policy.
