Effectiveness of Security Control Risk Assessments for Enterprises: Assess on the Business Perspective of Security Risks

ABSTRACT

Today's businesses being IT enabled, the complexity of risks affecting the business has increased manifold and the need to gauge the Information Technology risks acting on the business operations has become paramount. The business managers who run business operations need to operate securely and seamlessly leveraging Information Technology and ability to recover and resume the business without any loss of confidentiality, integrity and availability of business information/data in any event of a security incident.

There is a need to quantify the impact of the IT security risk on the critical business processes, and provide the business-level insight at the management level. It is critical to classifying the Risk Ratings as per the impact on the business operations. This approach allows the organizations to understand and prioritize the security risk management activities that make the most sense for their organization to secure the business operations instead of trying to protect against every conceivable threat.

Knobology in use: an experimental evaluation of ergonomics recommendations

The scientific basis for ergonomics recommendations for controls has usually not been related to active goal-directed use. The present experiment tests how different knob sizes and torques affect operator performance. The task employed is to control a pointer by the use of a control knob, and is as such an experimentally defined goal-directed task relevant to machine systems in general. Duration of use, error associated with use (overshooting of the goal area) and movement reproduction were used as performance measures. Significant differences between knob sizes were found for movement reproduction. High torques led to less overshooting as opposed to low torques. The results from duration of use showed a tendency that the differences between knob sizes were reduced from the first iteration to the second iteration. The present results indicate that the ergonomically recommended ranges of knob sizes might differently affect operator performance.     

基于控件和XML的可定制软件开发方案

为降低软件维护上的难度，适应不断变化的用户需求，提出了一种基于控件和XML配置技术的可定制的软件开发方案，一定程度上解决了面向Windows应用程序的可定制问题。该方案利用XML存储软件设计中的关键信息，将部分设计信息与开发平台分离，降低了和其它模块的耦合度，使得使用该方案开发的软件系统具有较高的可扩展性。该方案已经在一个电子元器件库存系统和一款印刷电路板的设置软件上得以应用。     

基于ActiveX技术的PPT作品探究

摘要：文章从实用角度出发,以ActiveX技术特征、ActiveX控件应用途径作为理论铺垫,在AcdveX控件的用法、环境安全性、非编辑环境下可靠运行三个层面,对AcdveX技术支持的OfficePowerpoint多媒体演示作品的制作进行了探究,以期为读者提供参考。文章认为：AcdveX技术不仅使Powerpoint针对flash动画、数字视频等动态媒体控制更加有效,而且还能实现动态文本输入、虚拟现实模型和全景电影的控制等功能。尽管基于该技术的作品在演示时,还不能完全脱离Office Powerpoint软件环境,但终究是增强和拓展了Office Powerpoint媒体集成功能。     

Planning for Areas Adjacent to National Parks in Victoria

Threats to national parks from development outside their boundaries are increasing especially on the urban fringe. This article examines the threats in Victoria and the USA. It looks at what has been done so far by town planners in Victoria to combat these threats. Various measures such as the use of siting and design guidelines, conservation covenants and agreements, zoning controls and the role of state and local government legislation are discussed. The article goes on to suggest what could be done. It discusses the importance of having buffer zones around parks in which the Department of Conservation and Natural Resources would become a statutory referral authority. The problems of defining the buffer zone and administering it are also discussed. The author calls for more co-operation between state and local government authorities to reduce these threats. How America handles these threats is also mentioned.
