Dynamic Security of Virtualized Systems: An Analysis of Time-based Impact

Virtualization technologies pose time-sensitive security challenges that need to be addressed from a dynamic security perspective. Adopting a dynamic security approach can help organizations manage the security risks inherent in virutalized environments. This paper conceptually examines current thought on best practices in information security systems which explains the dynamic nature of virtualized systems and paves the way for an information security model into which virtualization can be incorporated. We suggest that a proper analysis of timebased impact of security threats would help mitigate virtualization security risks, allowing IT security professionals and users to efficiently coordinate security objectives with the larger goals of the organization

Key aerodynamic technologies for aircraft engine nacelles

Customer requirements and vision in aerospace dictate that the next generation of civil transport aircraft should have a strong emphasis on increased safety, reduced environmental impact and reduced cost without sacrificing performance. In this context, the School of Mechanical and Aerospace Engineering at the Queen's University of Belfast and Bombardier have, in recent years, been conducting research into some of the key aerodynamic technologies for the next generation of aircraft engine nacelles. Investigations have been performed into anti-icing technology, efficient thrust reversal, engine fire zone safety, life cycle cost and integration of the foregoing with other considerations in engine and aircraft design. A unique correlation for heat transfer in an anti-icing system has been developed. The effect of normal vibration on heat transfer in such systems has been found to be negligible. It has been shown that carefully designed natural blockage thrust reversers without a cascade can reduce aircraft weight with only a small sacrifice in the reversed thrust. A good understanding of the pressure relief doors and techniques to improve the performance of such doors have been developed. Trade off studies between aerodynamics, manufacturing and assembly of engine nacelles have shown the potential for a significant reduction in life cycle cost

The Interplay of IT Governance Mechanisms, Value and Performance: The Case of Cloud Computing Investment

Background: Digital acceleration coupled with unprecedented work disruption (e.g., a Pandemic) have amplified the need for mature IT governance practices to generate planned value from organizations\u27 digital investments. Although the pairwise relationship between mature governance practices, value derived from IT investments, and organizational performance have been examined previously, all three have rarely been simultaneously investigated. Therefore, this paper examines the role of value in the relationship between IT governance mechanisms and organizational performance. Method: A research model that comprehensively conceptualizes the governance mechanism construct is developed and validated. The model is examined using data collected from 250 United States organizations that have invested in cloud computing for over a year. Results: The results reveal that the value generated from an IT investment is germane to understanding the relationship between governance mechanisms and organizational performance. Specifically, the result explains that governance mechanisms help improve organizational performance through cost reduction in IT services, create agility through flexibility in technology service, strengthen IT security and privacy, and effectively redirect IT resources. The results show the more critical role of the relational mechanism and practices related to IT security and privacy in the cloud computing context. Conclusion: The study contributes to IS literature by providing a more unified conceptualization of governance mechanisms and theoretically establishing the importance of governance in effectively governing cloud computing. By providing a guideline to help organizations achieve more value from cloud computing, the study provides implications for practice. The findings empirically show the relational mechanism has the most critical role in creating value from cloud computing. The governance practices help bridge the gap between business and IT, gradual transformative change in the roles and responsibilities, control cloud expenses, security and privacy risks. The findings show that competency is more likely to be achieved from cloud computing investment
