The incentive mechanism model of information security outsourcing is designed based on the principal-agent theory. Through analyzing the factors such as enterprise information assets value, invasion probability, information security environment, the agent cost coefficient and agency risk preference degree how to impact on the incentive mechanism, conclusions show that an enterprise information assets value and invasion probability have a positive influence on the fixed fee and the compensation coefficient; while information security environment, the agent cost coefficient and agency risk preference degree have a negative influence on the compensation coefficient. Therefore, the principal enterprises should reasonably design the fixed fee and the compensation coefficient to encourage information security outsourcing agency enterprises to the full extent.展开更多

The success of such a program depends primarily on the effective implementation and execution of associated information security policies and controls. These policies and controls depend directly upon the resultant behavior and actions of end-users. Hence, end-users play a critical role in the effective implementation and running of an information security program in any organization. However, end-users are often unable to navigate and comprehend the various policies, controls and associated issues. Support to end-users is therefore a vital element, but is often neglected by present information security management systems. In the service industry, support to customers is established as an important determinant of customer perceived service quality. This paper applies the same philosophy to provide support to end-users, who are the customers of the Information Security Service.展开更多

The study followed literature search techniques, as well as theoretical and empirical methods of factor validation. The strategy used in literature search includes Boolean keywords search, and citation guides, using mainly web of science databases. As guided by study objectives, 9 SM socio-technical factors were identified, verified and validated. Both theoretical and empirical validation processes were followed. Thus, a theoretical validity test was conducted on 45 Likert scale items, involving 10 subject experts. From the score ratings of the experts, Content Validity Index (CVI) was calculated to determine the degree to which the identified factors exhibit appropriate items for the construct being measured, and 7 factors attained an adequate level of validity index. However, for reliability test, 32 respondents and 45 Likert scale items were used. Whereby, Cronbach’s alpha coefficient (α-values) were generated using SPSS. Subsequently, 8 factors attained an adequate level of reliability. Overall, the validated factors include;1) usability—visibility, learnability, and satisfaction;2) education and training—help and documentation;3) SM technology development—error handling, and revocability;4) information security —security, privacy, and expressiveness. In this case, the confirmed factors would add knowledge by providing a theoretical basis for rationalizing information security requirements on SM usage.展开更多

文摘In order to solve principal-agent problems caused by interest inconformity and information asymmetry during information security outsourcing, it is necessary to design a reasonable incentive mechanism to promote client enterprises to complete outsourcing service actively. The incentive mechanism model of information security outsourcing is designed based on the principal-agent theory. Through analyzing the factors such as enterprise information assets value, invasion probability, information security environment, the agent cost coefficient and agency risk preference degree how to impact on the incentive mechanism, conclusions show that an enterprise information assets value and invasion probability have a positive influence on the fixed fee and the compensation coefficient; while information security environment, the agent cost coefficient and agency risk preference degree have a negative influence on the compensation coefficient. Therefore, the principal enterprises should reasonably design the fixed fee and the compensation coefficient to encourage information security outsourcing agency enterprises to the full extent.

文摘Industrial control systems(ICSs)are widely used in various fields,and the information security problems of ICSs are increasingly serious.The existing evaluation methods fail to describe the uncertain evaluation information and group evaluation information of experts.Thus,this paper introduces the probabilistic linguistic term sets(PLTSs)to model the evaluation information of experts.Meanwhile,we propose a probabilistic linguistic multi-criteria decision-making(PL-MCDM)method to solve the information security assessment problem of ICSs.Firstly,we propose a novel subscript equivalence distance measure of PLTSs to improve the existing methods.Secondly,we use the Best Worst Method(BWM)method and Criteria Importance Through Inter-criteria Correlation(CRITIC)method to obtain the subjective weights and objective weights,which are used to derive the combined weights.Thirdly,we use the subscript equivalence distance measure method and the combined weight method to improve the probabilistic linguistic Visekriterijumska Optimizacija I Kompromisno Resenje(PL-VIKOR)method.Finally,we apply the proposed method to solve the information security assessment problem of ICSs.When comparing with the existing methods such as the probabilistic linguistic Tomada deDecisão Iterativa Multicritério(PL-TODIM)method and probabilistic linguistic Technique for Order Preference by Similarity to Ideal Solution(PL-TOPSIS)method,the case example shows that the proposed method can provide more reasonable ranking results.By evaluating and ranking the information security level of different ICSs,managers can identify problems in time and guide their work better.
文摘The Intemet is a popular channel for allowing more and more users to exchange information without geographical limitations and time restrictions. Therefore, a large amount of digital data, such as digital images, text, audio, and video, is transmitted over the Intemet. Unfortunately, sensitive digital data can be intercepted by malicious users of the Internet, so the development of techniques for ensuring the secrecy and security of data during transmission has become a top priority.

文摘Security evaluation and management has become increasingly important for Web-based information technology(IT)systems,especially for educational institutions.For the security evaluation and management of IT systems in educational institutions,determining the security level for a single IT system has been well developed.However,it is still dificult to evaluate the information security level of the entire educational institution consid-ering multiple IT systems,because there might be too many different IT systems in one institution,educational institutions can be very different,and there is no standard model or method to provide a just ifable information security evaluation among different educational inst itutions considering their differences.In light of these difi-culties,a security evaluation model of educational institutions'IT systems(SEMEIS)is proposed in this work to facilitate the information security management for the educat ional institutions.Firstly,a simplified educational industry information system security level protection rating(EIISSLPR)with a new weight redistribution strategy for a single IT systern is proposed by choosing important evaluation questions from EIISSLPR and redistributing the weights of these questions.Then for the entire educational institution,analytic hierarchy process(AHP)is used to redistribute the weights of multiple IT systems at different security levels.considering the risk of pos-sible network security vulnerabilities,a risk index is forulated by weighting different factors,normalized by a utility function,and calculated with the real data collected from the institutions under the evaluation.Finally,the information security performance of educational institutions is obtained as the final score from SEMEIS.The results show that SEMEIS can evaluate the security level of the educat ion institutions practically and provide an efficient and effective management tool for the information security management.
