Managing security risks for inter-organisational information systems: a multiagent collaborative model

Information sharing across organisations is critical to effectively managing the security risks of inter-organisational information systems. Nevertheless, few previous studies on information systems security have focused on inter-organisational information sharing, and none have studied the sharing of inferred beliefs versus factual observations. In this article, a multiagent collaborative model (MACM) is proposed as a practical solution to assess the risk level of each allied organisation’s information system and support proactive security treatment by sharing beliefs on event probabilities as well as factual observations. In MACM, for each allied organisation’s information system, we design four types of agents: inspection agent, analysis agent, control agent, and communication agent. By sharing soft findings (beliefs) in addition to hard findings (factual observations) among the organisations, each organisation’s analysis agent is capable of dynamically predicting its security risk level using a Bayesian network. A real-world implementation illustrates how our model can be used to manage security risks in distributed information systems and that sharing soft findings leads to lower expected loss from security risks.

计量体系的建设与应用

计量体系包括标准的建设及以技术为手段的计量管理。标准是衡量质量高低的基本依据,各项标准的实施,又要以相应的计量检测和科学的计量管理为技术手段和管理基础。企业计量体系运行的成功与否,直接关系到产品质量结果的控制。经过陕西省质量技术监督初审和2次复查考核,2008年1月份,建标申请经考核合格后获得了授权,并于2月份,压力类强检仪表也获得了对内强检资质。长庆油田分公司第二采气厂计量体系的建设与运行步入正规化、运行基本实现了专业化。     

Industry competition in China: an external governance mechanism or an external incentive

We focus on the impact of industry competition on earnings management in listed companies in China. Empirical analysis reveals the following: (1) When competition within an industry is relatively low, it lowers the extent of earnings management; (2) when competition is relatively high, earnings management is promoted.; (3) within an industry, the more intense the competition, the more companies manipulate earnings when in an inferior competitive position; and (4) state‐owned enterprises that are at a competitive disadvantage within an industry rely more on real earnings management strategies, whereas these effects are insignificant in private firms.
