an analytic hierarchy process based risk Assessment Method for wireless networks
IEEE Transactions on Reliability, 2011Co-Authors: Hsinyi Tsai, Yulun HuangAbstract:This paper presents a wireless risk Assessment Method to help an administrator manage wireless network security. The Assessment Method consists of a risk model and an Assessment measure. The risk model is in charge of modeling the wireless network risk. Security requirements, wireless attacks, and system configurations are considered in the model. The Assessment measure is an algorithm which determines the risk value of the wireless network according to the risk model. Our risk model is developed upon an extended analytic hierarchy process, which contains the 4 layers: the risk layer, the requirement layer, the attack layer, and the configuration layer. The separate layers of the risk model are helpful in dealing with the dynamics of a wireless network because only the related layers are introduced to the Assessment measure when changes of the network are detected. Based on the risk model per device, our Assessment measure evaluates the wireless network risk in consideration of the relations between devices, attacks, and configurations. Hence, our risk Assessment Method, composed of the risk model and the Assessment measure, can determine the wireless network risk efficiently while considering the dependencies in the wireless network. Two examples are introduced in this paper to examine the feasibility of our Method. In the first example, we demonstrate that the risk values derived by our Method meet the ground truth by performing practical experiments. The second example shows that our Method can evaluate the risk of a changing wireless network with efficiency, and can distinguish disparities in different wireless networks.

Risk Assessment Method of Information System Based on Threat Analysis
Computer Engineering, 2004Co-Authors: Lin MengquanAbstract:There are many risk Assessment Methods for information system, and in this paper the quantitative risk Assessment Method based on threat analysis is presented. The Assessment processes, two kinds of quantitative practices, the absolute one and the relative one, and the analysis of the advantages and drawbacks for the two practices, also the example demonstrations are provided.

Vulnerability threat correlation Assessment Method
Journal of Computer Applications, 2012Co-Authors: Yang Hong-yuAbstract:Since the present network security Assessment Methods cannot evaluate vulnerability relevance effectively,a vulnerability threat Assessment Method based on relevance was presented.Firstly,an attack graph must be created as the source data.Secondly,by taking both pre-nodes and post-nodes diversity into consideration,integrating the Methods of Forward In(FI) and Backward Out(BO),the authors calculated the probability of vulnerability being used on multiple attack routes through optimizing calculation formulas originating from Bayesian network,then the weighted average Method was utilized to evaluate the risk of certain vulnerability on a particular host,and finally the quantitative results were achieved.The experimental results show that this Method can clearly and effectively describe the security features of systems.

Analyzing work organization on livestock farm by the Work Assessment Method
Agronomy for Sustainable Development, 2018Co-Authors: Sylvie Cournut, Nathalie Hostiou, Sophie Chauvat, Pastora Correa, Joel Carneiro Dos Santos Filho, Francisco Diéguez, Duy Khanh Pham, Gérard Servière, Mohammed Taher Sraïri, Amélie TurlotAbstract:All over the world, farmers have to face up to increasing uncertainties (market and climate). They have to adapt their activity to the new contexts and challenges of livestock farming (producing more and better, and satisfying the expectations of society, consumers, and of downstream operators), while at the same time responding to their own expectations in terms of income, quality of life, and working conditions. In order to understand these changes and consider the future, work organization must be taken into account. The Work Assessment Method, developed by French livestock researchers, provides a framework able to capture work organization, taking into account the specifics of the livestock activity. Based on a comparative analysis of nine case studies that used the Work Assessment Method from six contrasted countries, this review (1) gives generic ideas on work organization indicators and their variation; (2) identifies four generic patterns of work organization which are not linked to the local context but marked by the workforce composition; (3) demonstrates that the relevance of the Work Assessment Method to tackle work issues, and its capacities to be adapted to a variety of livestock farming contexts throughout the world, is linked to the properties of its framework, which was developed by combining different disciplinary approaches; (4) highlights the principal limits of the Method: lack of coordination with other dimensions of work (labor productivity; sense of the job), and limited characterization of the work organization flexibility; and (5) proposes some possibilities of change to better respond to the diversity of work situations and questions about work, and take better into account the evolutions of livestock farming systems.
