Evaluation of a hash-compress-encrypt pipeline for storage system applications
2015
Great efforts are made to store data in a secure, reliable, and authentic way in large storage systems. Specialized, system specific clients help to achieve these goals. Nevertheless, often standard tools for hashing, compressing, and encrypting data are arranged in transparent pipelines. We analyze the potential of Unix shell pipelines with several high-speed and high-compression algorithms that can be used to achieve data security, reduction, and authenticity. Furthermore, we compare the pipelines of standard tools against a house made pipeline implemented in C++ and show that there is great potential for performance improvement.
Bot recognition in a Web store: An approach based on unsupervised learning
2020
Abstract Web traffic on e-business sites is increasingly dominated by artificial agents (Web bots) which pose a threat to the website security, privacy, and performance. To develop efficient bot detection methods and discover reliable e-customer behavioural patterns, the accurate separation of traffic generated by legitimate users and Web bots is necessary. This paper proposes a machine learning solution to the problem of bot and human session classification, with a specific application to e-commerce. The approach studied in this work explores the use of unsupervised learning (k-means and Graded Possibilistic c-Means), followed by supervised labelling of clusters, a generative learning stra…

A roadmap towards improving managed security services from a privacy perspective
2014
Published version of an article in the journal: Ethics and Information Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s10676-014-9348-3 This paper proposes a roadmap for how privacy leakages from outsourced managed security services using intrusion detection systems can be controlled. The paper first analyses the risk of leaking private or confidential information from signature-based intrusion detection systems. It then discusses how the situation can be improved by developing adequate privacy enforcement methods and privacy leakage metrics in order to control and reduce the leakage of private and confidential information over time. Such metrics should allow fo…

Cyber-Physical Systems for Smart Water Networks: A Review
2021
Author's accepted manuscript. There is a growing demand to equip Smart Water Networks (SWN) with advanced sensing and computation capabilities in order to detect anomalies and apply autonomous event-triggered control. Cyber-Physical Systems (CPSs) have emerged as an important research area capable of intelligently sensing the state of SWN and reacting autonomously in scenarios of unexpected crisis development. Through computational algorithms, CPSs can integrate physical components of SWN, such as sensors and actuators, and provide technological frameworks for data analytics, pertinent decision making, and control. The development of CPSs in SWN requires the collaboration of diverse scienti…
Human security: an analytical tool for disaster perception research
2015
Purpose – The purpose of this paper is to examine the possible benefits arising from the application of the human security concept to analysing the disaster impacts. Design/methodology/approach – A three-piece human security analytical tool is synthesized by combining the discoveries in human security studies over the last two decades with the perspective of disaster studies focusing on the resilience and securitabilities of the affected societies. To illustrate the merit of the proposed analytical framework a specifically tailored social survey is used to measure the resilience of Ogre’s (Latvia) society after it faces major floods in 2013. It foresees that community’s resilience is inver…
The development of work values during the transition to adulthood: A two-country study
2017
Abstract This study addresses the development of work values—the desired characteristics of one's current or future job—during young adulthood. Using two panel studies from Germany ( N = 2506) and Finland ( N = 1326), we investigated (a) mean-level and rank-order change and stability in work values across three biennial waves (age 20/21 to age 25/26); and (b) the influence of stable background characteristics as well as of major transitions in family and work roles on inter-individual differences and intra-individual changes in work values. Latent measurement models with three work value dimensions showed good fit in both countries: extrinsic (importance of job security and material rewar…
On the evolution of e-Government: The user imperative
2003
Published version of a chapter published in Lecture Notes in Computer Science, 2739, 139-143. Also available from the publisher at: http://dx.doi.org/10.1007/10929179_25 This paper focuses the need for more research on user involvement and the investigation of stakeholders in e-Government initiatives. An investigation of existing work revealed a lack of research on those topics. As e-Government evolves and users mature, the value of their input can increase. The paper discusses the need and potential benefits of this approach. Finally, we suggest that existing stakeholder theory is investigated for adaptation into e-Government settings in order to map the complex body of interrelated stakeh…
