The synthesis of complex systems

In systems synthesis the basic lesson-and the hardest to accept-is that not all engineering problems can be or should be solved by deduction from mathematical and scientific principles. Synthesis is provisional and qualitative, a way of thinking different from the definitive, quantitative thinking of analysis. Its technique and tools reflect this difference. In synthesizing the system's initial concept, three qualitative techniques are fundamental: heuristics, metaphors, and models. Heuristics are brief statements of lessons learned in the past and applicable to the present situation. Metaphors transpose the implicit behavior of a system to a more familiar context, one example is the desktop metaphor for personal computer operating systems. Models are used to present different perspectives of a proposed system to multiple stakeholders so that everyone has a common frame of reference for discussion. Progressive modeling emphasizes the continuing refinement of models during system development than, say, an initial sketch to full-scale simulator. Each of these qualitative techniques are discussed.     

Evaluating the web‐application resiliency to business‐layer DoS attacks

A denial‐of‐service (DoS) attack is a serious attack that targets web applications. According to Imperva, DoS attacks in the application layer comprise 60% of all the DoS attacks. Nowadays, attacks have grown into application‐ and business‐layer attacks, and vulnerability‐analysis tools are unable to detect business‐layer vulnerabilities (logic‐related vulnerabilities). This paper presents the business‐layer dynamic application security tester (BLDAST) as a dynamic, black‐box vulnerability‐analysis approach to identify the business‐logic vulnerabilities of a web application against DoS attacks. BLDAST evaluates the resiliency of web applications by detecting vulnerable business processes. The evaluation of six widely used web applications shows that BLDAST can detect the vulnerabilities with 100% accuracy. BLDAST detected 30 vulnerabilities in the selected web applications; more than half of the detected vulnerabilities were new and unknown. Furthermore, the precision of BLDAST for detecting the business processes is shown to be 94%, while the generated user navigation graph is improved by 62.8% because of the detection of similar web pages.

Software engineering for telecommunications : bringing research results into industrial practice

As networks and services are becoming more and more sophisticated, telecommunications software is growing in complexity. But, despite growing industrial needs, progress towards more software productivity has been extremely slow. This paper considers the software engineering problems from an industrial point of view. The industrial environment is therefore presented in some detail, stressing the influence of major events (e.g. company mergers) on fundamental software development issues (e.g. configuration management). The evolution of this environment, caused by recent trends such as deregulation, is then described, forecasting the consequences for software development. Then some emerging software techniques are presented as applied (or applicable) to telecommunications software. The paper concludes with a discussion of several research issues that could be of interest for industry within a reasonable time-frame.     

Vacuum Web Coating - State of the Art and Potential for Electronics

Going flexible seems to be a major trend for a variety of electronic applications such as displays, printed circuit boards, solar cells, and solid-state lighting. Driving forces, which may often include the function of "flexibility," are the potential to build units with less thickness and with less weight or the ability for very-large-area applications. Last but not least, there is the need for a remarkable reduction of production costs, which can be fulfilled by changing the production process from sheet processing to roll to roll. The first vacuum web coater was built 70 years ago, and vacuum web coating is currently used for a wide variety of applications. In the packaging industry, aluminum coating is primarily used for barrier improvement of plastic substrates. Such coatings are deposited with an evaporation process in machines of up to 4-m coating widths on rolls up to 60 000-m length and at coating speeds of more than 16 m/s. For capacitor production, thin webs with thicknesses down to the submicrometer range are vacuum-coated with aluminum, silver, or zinc layers, and uncoated stripes or patterns are also needed. Vacuum-coated web-shaped substrates can also be used for antireflective, antistatic function in the front of monitors, as window films for cars and architectural applications or as front electrodes for touch panels as a few examples. Different coating tools such as evaporation, sputtering, plasma-enhanced chemical-vapor deposition (PECVD), as well as pretreatment tools and inline layer measurement systems are available. Many of the currently available tools and processes existing in the web coating industry may become useful for upcoming electronic applications, but special demands for these new applications, such as exact area tracking, zero defects, roll-to-roll masking, and reduced substrate temperature during coating, require further development of machine design and process technology. This paper will summarize the state of the art of vacuum w

Clickjacking: Beware of Clicking

Clickjacking is a newly discovered breach in network security. It is based on the functionality of web-designing in which two or more web frames are overlapped over each other. The analysis shows that there is a need for in-depth study on click-jacking attacks (client-side vulnerability) and preventive measures so that early prevention and detection of such kinds of attacks can be implemented in a timely manner. In this research work, most of the client-side attacks are studied and an overview of the clickjacking techniques is presented to provide insights into the area of network security to the researchers. The overview of tools and techniques used by attackers are also investigated along with the prevention measures.
