面向业务:信息安全保障业务发展新趋势

如今信息安全在信息社会扮演极为重要的角色,直接关系到政府运作、企业经营和人们的日常生活,信息安全服务也已成为信息安全保障体系的重要内容。然而国内信息安全服务行业却存在很多问题,管理者的信息安全意识不足,安全服务以事件应急响应为主,忽视为客户提供主动、系统的面向业务的服务。针对这一现状,本文提出了基于业务的信息安全服务体系(Business-based Information Security Service System,BISSS),利用企业架构(Enterprise Architecture,EA)对机构及其信息系统进行分析,以信息系统的业务属性为出发点和依据,为客户提供覆盖整个信息系统生命周期的安全服务。     

大规模分布式系统脆弱性分析框架研究

随着大规模分布式系统在国家安全、经济运行、基础设施、社会生活等方面扮演的角色越来越重要,其脆弱性分析问题日益成为人们关注的焦点。将大规模分布式系统视为脆弱性分析对象,构建了大规模分布式系统的层次模型,分析了大规模分布式系统的脆弱性类型,提出了基于生命周期的多维度的大规模分布式系统脆弱性分析框架,从脆弱性分析阶段、生命周期以及脆弱性类型等方面系统地梳理了研究方向。     

新环境下的信息系统安全开发与测试

随着信息化技术的不断发展,现有的信息系统在架构和用户体验上得到不断提升,软件开发的模式也通过敏捷,SaaS等方式得到不断的发展。但与此同时伴随着用户量的增长和用户对信息的敏感,安全问题长期困扰各类软件和互联网公司,软件的安全开发和测试不得不成为的信息系统在新环境下所面临的考验和待解决的关键问题之一。从分析新环境下信息系统研发安全需求入手,着重讨论了在软件生命周期中如何利用微软SDL来进行安全开发,并结合作者提出的安全测试方法来有效提高信息系统的安全性和解决敏感信息泄露等问题。     

Collaborative product innovation: integrating elements of CPI via PLM framework

Information technology has evolved over the last few decades at an extremely rapid pace. In the last few years, Internet technology has contributed towards how organizations mature, evolve their business, implement processes and chalk out business strategies for product development to meet customer requirements. Yet the true potential of technology lies in its ability to connect people, processes and information and for this to be realized the target user group for technology will have to be a captive audience. For organizations the world over this captive audience are its employees, suppliers and customers.This paper attempts at integrating three topics using a technology framework for capturing the benefits that can be harnessed by organizations, these are Collaboration, Product Development and Innovation, as the topic suggests, CPI, ‘Collaborative Product Innovation’.     

Decision Making and Institutional Design for Product Lifecycle Management

This paper proposes a new approach to decision making and institutional design for product lifecycle management based on social systems engineering. Product lifecycle problems are limited not only by technological issues, but also by economic and social issues. We construct an agent-based model of decision making systems consisting of human subjects such as producers, consumers, dismantlers and used-unit dealers. The focal point of this study is the analysis of which economic agents should collect used units and how product durability affects the formation of a recycling society. This paper also presents discussion of institutional design by comparing experimental results with current institutions using real-world data for several types of products.     

LIFECYCLE SAFETY GUARANTEE OF STRUCTURES

The principles for lifecycle safety guarantee of engineering structures are proposed, and the conception is developed for developing the safety guarantee system by integrating the monitoring system, analysis system and maintenance system together on the basis of multi-sensor, distribution-measurement, data fusion and digital-signal-processor (DSP) technologies as well as three-dimensional (3D) fatigue fracture unified theory. As all the systems should work in situs and in real-time, micromation and integration are important. Damage detectability is introduced to clarify the relationship of life prediction and healthy monitoring or faulty diagnosis. The research work to realize the lifecycle safety guarantee system is summarized and perspectives for future efforts are outlined.

Assessing social impacts in a life cycle perspective—Lessons learned

In our globalised economy, important stakeholder groups nowadays hold companies responsible for the social impacts they cause in their product chain through activities like child labour, corruption or discrimination of employees. Many companies thus see themselves in need of a tool which can help them make informed decisions about their social impacts throughout the life cycle of their products. The paper presents lessons learned from four years of work with industry on development of a methodology for Social Life Cycle Assessment and implementation in the industrial product chain. The Social LCA methodology supplements the traditional environment-oriented LCA and the life cycle costing tools in support of sustainability management addressing all three pillars of sustainability: people, planet and profit.     

浅谈产品设计与可持续发展

随着经济的快速发展,地球上的环境不断恶化,资源也面临枯竭的状况,人们开始将眼光转向可持续发展。产品设计对于可持续发展来说是一个相当关键的环节。本文在简要介绍产品设计与可持续发展关系的基础上,重点分析了可持续发展对产品设计提出的新要求,并从产品全生命周期出发探讨了如何针对可持续发展提出的新要求进行产品设计。     

Reliability and performance-based design

Structural failures in recent earthquakes and hurricanes have exposed the weakness of current design procedures and shown the need for new concepts and methodologies for building performance evaluation and design. A central issue is proper consideration and treatment of the large uncertainty in the loadings and the complex building behavior in the nonlinear range in the evaluation and design process. A reliability-based framework for design is proposed for this purpose. Performance check of the structures is emphasized at two levels corresponding to incipient damage and incipient collapse. Minimum lifecycle cost criteria are proposed to arrive at optimal target reliability for performance-based design under multiple natural hazards. The issue of the structural redundancy under stochastic loads is also addressed. Effects of structural configuration, ductility capacity, 3-D motions, and uncertainty in demand versus capacity are investigated. A uniform-risk redundancy factor is proposed to ensure uniform reliability for structural systems of different degree of redundancy. The inconsistency of the reliability/redundancy factor in current codes is pointed out.
