A Flexible Framework for Architecting XML Access Control Enforcement Mechanisms

Purpose – The paper aims to propose a flexible framework to support X-STROWL model. Extensible access control markup language (XACML) is an international standard used for access control in distributed systems. However, XACML and its existing extensions are not sufficient to fulfill sophisticated security requirements (e.g. access control based on user’s roles, context-aware authorizations and the ability of reasoning). Remarkably, X-STROWL, a generalized extension of XACML for spatiotemporal role-based access control (RBAC) model with reasoning ability, is a comprehensive model that overcomes these shortcomings. It mainly focuses on the architecture design as well as the implementation and evaluation of proposed framework and the comparison with others. Design/methodology/approach – Based on the concept of X-STROWL model, the paper reviewed a large amount of open sources implementing XACML with defined criteria and chose the most suitable framework to be extended for the implementation. The paper also presented a case study used to evaluate the research result. Findings – Holistic enterprise-ready application security framework – architecture framework (HERAS-AF) is chosen as the most suitable framework to be extended to implement X-STROWL model. Extending HERAS-AF to support spatiotemporal aspect and other contextual conditions as well as the way to integrate security in the access request, together with ability of reasoning for hierarchical roles, are striking features that make the proposed framework able to meet more sophisticated security requirements in comparison with others. Research limitations/implications – Due to the research content, the performance of proposed framework is not the focused issue of this work. Originality/value – The proposed framework is a crucial contribution of our research to provide a holistic, extensible and intelligent authorization decision engine.

Abstract. Meta-accuracy and perceptions of reciprocity can be measured by covariances between latent variables in two social relations models examining perception and meta-perception. We propose a single unified model called the Perception-Meta-Perception Social Relations Model (PM-SRM). This model simultaneously estimates all possible parameters to provide a more complete understanding of the relationships between perception and meta-perception. We describe the components of the PM-SRM and present two pedagogical examples with code, openly available on https://osf.io/4ag5m . Using a new package in R (xxM), we estimated the model using multilevel structural equation modeling which provides an approachable and flexible framework for evaluating the PM-SRM. Further, we discuss possible expansions to the PM-SRM which can explore novel and exciting hypotheses.

Flexible Framework

Stochastic dependence among cognitive processes can be modeled in different ways, and the family of multinomial processing tree models provides a flexible framework for analyzing stochastic dependence among discrete cognitive states. This article presents a multinomial model of multidimensional source recognition that specifies stochastic dependence by a parameter for the joint retrieval of multiple source attributes together with parameters for stochastically independent retrieval. The new model is equivalent to a previous multinomial model of multidimensional source memory for a subset of the parameter space. An empirical application illustrates the advantages of the new multinomial model of joint source recognition. The new model allows for a direct comparison of joint source retrieval across conditions, it avoids statistical problems due to inflated confidence intervals and does not imply a conceptual imbalance between source dimensions. Model selection criteria that take model complexity into account corroborate the new model of joint source recognition.

Current Stage

China’s Belt and Road Initiative could be treated ambiguously. On the one hand, it is intended to transform the newly acquired economic potential of that country into its higher status in the world. China invites a lot of nations to build up gigantic transit corridors by joint efforts, and doing so it applies productively its capital and technologies. International transactions in RMB are also being expanded. But, on the other hand, the Belt and Road Initiative is also a necessity for China to cope with some evident problems of its current stage of development, such as industrial overcapacity, overdependence on imports of raw materials from a narrow circle of countries, and a subordinate status in global value chains. For Russia participation in the Belt and Road Initiative may be fruitful, since the very character of that project provides us with a space to manoeuvre. By now, Russian exports to China consist primarily of fuels and other commodities. More active industrial policy is needed to correct this situation . A flexible framework of the Belt and Road Initiative is more suitable for this objective to be achieved, rather than traditional forms of regional integration, such as a free trade zone.
