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.

인터넷전화의 활성화와 더불어 SIP 프로토콜의 사용이 증가하고 있다. 최근 DDoS 공격이 주요위협으로 이슈가 되고 있으며, 향후 SIP관련 서비스 대상 서비스 거부 공격 위협도 증가할 것으로 예상된다. 본 논문에서는 SIP 프로토콜의 특성을 이용한 SIP서비스 거부 공격들의 유형을 살펴보고, SIP 프로토콜의 특성을 이용한 서비스거부 공격 탐지를 위한 고려사항을 바탕으로 분석시스템 아키텍처를 제안한다. SIP서비스 거부공격의 유형은 분류 기준에 따라 다양할 수 있으나, 본 논문에서는 SIP 프로토콜의 특성을 이용한 공격 기법을 대상으로 한다. SIP서비스 거부 공격 트래픽 분석을 위해 정보수집, 정보분석, 정보관리 기능을 고려한다.

All industries has expanded their research investment for development and secure of new technology, following application of ICT technology and rapid growth of industrial technology. Therefore efforts to protect the new technology have strengthened. Several governments have conducted a variety of industrial security activities with interest because these efforts are considered not only business problem level but also national level. In this paper, we research the industrial security related organization that performs the activities for industrial assets protection and technology drain prevention. Furthermore we discuss problems with the industrial security performance of government and emphasize the necessity of industrial security department in government.

This study proceeded to examine the cause of the continuous secret information leakage in the firms. The purpose of this study is to find out what type of security among administrative, technological and physical security would have important influence on firm's security performance such as the security-incident response competence. We established the model that can empirically verify correlation between those three types of security and the security-incident response competence. In addition, We conducted another study to look at relation between developing department of security in the firms and reaction ability at the accidents. According to the study, the administrative security is more important about dealing with the security-incident response competence than the rest. Furthermore, a group with department of security has better the security-incident response competence and shows higher competence in fixing or rebuilding the damage. Therefore, this study demonstrates that investing in administrative security will be effective for the firm security.

As regulatory bodies require full implementation of security controls in nuclear power plants (NPPs), security functions for critical digital assets are currently being developed. For the ultimate introduction of security controls, not alternative measures, it is important to understand the relationship between possible cyber threats to NPPs and security controls to prevent them. To address the effectiveness of the security control implementation, this study investigated the types of cyber threats that can be prevented when the security controls are implemented through the mapping of the reorganized security controls in RS-015 to cyber threats on NPPs. Through this work, the cyber threat that each security control can prevent was confirmed, and the effectiveness of several strategies for implementing the security controls were compared. This study will be a useful reference for utilities or researchers who cannot use design basis threat (DBT) directly and be helpful when introducing security controls to NPPs that do not have actual security functions.

Active networks allow active node’s functionality to be extended dynamically through the use of active extensions. This flexible architecture facilitates the deployment of new network protocols and services. However, the active nature of a network also raises serious safety and security concerns. These concerns must be addressed before active networks can be deployed. In this paper we look at how we can control active extension’s access to different active nodes. Specifically, the authentication between active nodes is very important in this case. We use unique identity each node has for transferring access policies between active nodes. In this paper, we suggest a new method of transferring access policies performing authentications using identities between active nodes.

Security is still a great concern to this day, albeit we have come a long way to mitigate its numerous threats. No-SQL databases are rapidly becoming the new database de-facto, as more and more apps are being developed every day. However, No-SQL databases security could be improved. In this paper, we discuss a way to improve the security of XML-based databases with the use of trust labels to be used as an access control model.

According to arriving convergence environment which can create new value-added converged between industry and ICT technology, It has made economic growth and improve the quality of life. However this convergence environment provide not only advantage but also various security problems resulting from generating converged security threats. For resolving this security problem, we need to approach to security problem in the integrated view not the fragmentary view which cover only technical approach. So This study developed security governance framework which can manage trustful security governance in multidimensional view which cover strategy, managerial/operational and technical view. Therefore this framework can construct trustful security management system which can help top management team to engage in security management directly and organizational member to perform security activities and have responsibility for themselves as suggesting single standard for security management.

The amount of Big Data generated from multiple sources is continuously increasing. Traditional storage methods lack the capacity for such massive amounts of data. Consequently, most organizations have shifted to the use of cloud storage as an alternative option to store Big Data. Despite the significant developments in cloud storage, it still faces many challenges, such as privacy and security concerns. This paper discusses Big Data, its challenges, and different classifications of security and privacy challenges. Furthermore, it proposes a new classification of Big Data security and privacy challenges and offers some perspectives to provide solutions to these challenges.

This article substantiates the scientific provisions for modelling the level of Ukraine's public financial security taking into account the impact of budget policy, in the process of which identified indicators of budget policy that significantly affect the public financial security and the factors of budget policy based on regression analysis do not interact closely with each other. A seven-factor regression equation is constructed, which is statistically significant, reliable, economically logical, and devoid of autocorrelation. The objective function of maximizing the level of public financial security is constructed and strategic guidelines of budget policy in the context of Ukraine's public financial security are developed, in particular: optimization of the structure of budget revenues through the expansion of the resource base; reduction of the budget deficit while ensuring faster growth rates of state and local budget revenues compared to their expenditures; optimization of debt serviced from the budget through raising funds from the sale of domestic government bonds, mainly on a long-term basis; minimization of budgetary risks and existing threats to the public financial security by ensuring long-term stability of budgets etc.
