Increasing resilience of ATM networks using traffic monitoring and automated anomaly analysis

Systematic network monitoring can be the cornerstone for the dependable operation of safety-critical distributed systems. In this paper, we present our vision for informed anomaly detection through network monitoring and resilience measurements to increase the operators' visibility of ATM communication networks. We raise the question of how to determine the optimal level of automation in this safety-critical context, and we present a novel passive network monitoring system that can reveal network utilisation trends and traffic patterns in diverse timescales. Using network measurements, we derive resilience metrics and visualisations to enhance the operators' knowledge of the network and traffic behaviour, and allow for network planning and provisioning based on informed what-if analysis

Towards a Layered Architectural View for Security Analysis in SCADA Systems

Supervisory Control and Data Acquisition (SCADA) systems support and control the operation of many critical infrastructures that our society depend on, such as power grids. Since SCADA systems become a target for cyber attacks and the potential impact of a successful attack could lead to disastrous consequences in the physical world, ensuring the security of these systems is of vital importance. A fundamental prerequisite to securing a SCADA system is a clear understanding and a consistent view of its architecture. However, because of the complexity and scale of SCADA systems, this is challenging to acquire. In this paper, we propose a layered architectural view for SCADA systems, which aims at building a common ground among stakeholders and supporting the implementation of security analysis. In order to manage the complexity and scale, we define four interrelated architectural layers, and uses the concept of viewpoints to focus on a subset of the system. We indicate the applicability of our approach in the context of SCADA system security analysis.Comment: 7 pages, 4 figure

Report from GI-Dagstuhl Seminar 16394: Software Performance Engineering in the DevOps World

This report documents the program and the outcomes of GI-Dagstuhl Seminar 16394 "Software Performance Engineering in the DevOps World". The seminar addressed the problem of performance-aware DevOps. Both, DevOps and performance engineering have been growing trends over the past one to two years, in no small part due to the rise in importance of identifying performance anomalies in the operations (Ops) of cloud and big data systems and feeding these back to the development (Dev). However, so far, the research community has treated software engineering, performance engineering, and cloud computing mostly as individual research areas. We aimed to identify cross-community collaboration, and to set the path for long-lasting collaborations towards performance-aware DevOps. The main goal of the seminar was to bring together young researchers (PhD students in a later stage of their PhD, as well as PostDocs or Junior Professors) in the areas of (i) software engineering, (ii) performance engineering, and (iii) cloud computing and big data to present their current research projects, to exchange experience and expertise, to discuss research challenges, and to develop ideas for future collaborations

A survey on online monitoring approaches of computer-based systems

This report surveys forms of online data collection that are in current use (as well as being the subject of research to adapt them to changing technology and demands), and can be used as inputs to assessment of dependability and resilience, although they are not primarily meant for this use

Microfinancing Influence on Micro-Entrepreneurs Business Growth: Mediating Role of Psychological and Social Capital

This paper is set out to uncover the phenomena of micro-enterprises business growth by hypothesizing microfinancing, social and psychological capital as factors. This research is important due to the fact that the paucity of information on how microfinancing, social and psychological capital relate to micro-enterprises business growth would obscure the ways in which they survive. In Malaysia, microfinance is used as one of the tools to alleviate poverty, as well as to improve the livelihood and standards of living of the poor and those who are financially excluded.  However, almost three decades after the introduction of microfinancing programmes, the performance of microfinancing recipients’ i.e. micro-enterprises in Malaysia is not satisfactory. Besides providing loans to these micro-entrepreneurs, other aspects of facilitation, including the inculcation of the entrepreneur’s intangible resources, need to be addressed. Therefore, this research examines the mediating effect of micro-entrepreneurs’ psychological and social capital on the relationship between microfinance provisions and the business growth of micro-enterprises. The samples are identified from two microfinance providers, i.e., Amanah Ikhtiar Malaysia (AIM) and the National Entrepreneur Group Economic Fund (TEKUN) micro credit financing scheme recipients’ databases. A total of 250 useable survey questionnaires was collected and analysed to test the hypothesised relationship. The data was analysed using Partial Least Square-SEM and the structural model was examined to test the hypotheses. The findings show that micro-entrepreneurs’ psychological and social capital have a significant mediating effects on the relationship between provision of microfinance and the business growth of micro-enterprises in Kelantan. This research offers the practical implication that the effects of micro finance provision on the business growth of micro-enterprises are better exerted through micro-entrepreneurs’ psychological and social capital. This theoretically supports the applicability of the Resource-based View (RBV) theory to explain the mediating effect of psychological and social capital on the relationship between microfinance provisions and business growth.

Exploratory Research into the Resilience of Farming Systems during Periods of Hardship

This paper investigates the management strategies and responses used by New Zealand sheep and beef farmers to ensure resilience during periods of hardship. Using two, farm level surveys conducted in 1986 and 2010, some aspects of resilient farming systems were identified. Despite apparent hardship current farmers seemed more willing to take risks, with many more borrowing to invest in on farm developments than those in 1986. The main similarity between time periods was the greatest response to economic changes being the adoption of a low input policy. This result was quite significant, as conventional farmers are generally believed to resort to other strategies or responses.Resilience, New Zealand, indicators, sustainable agriculture, strategies, Agribusiness, Environmental Economics and Policy, Land Economics/Use, Production Economics,
