Access to Electronic Data for Criminal Investigations Purposes in the EU. CEPS Paper in liberty and security in Europe No. 2020-01, February 2020

Within the EU and across the Atlantic, investigation and prosecution of crime increasingly relies on the possibility to access, collect and transfer electronic information and personal data held by private companies across borders. Cross-border access to and collection of data for the purpose of fighting crime raise several legal and jurisdictional issues. This paper comparatively examines the constitutional, legal and administrative frameworks on access to and use of digital information in cross-border criminal justice cooperation in a selection of EU member states. It presents key challenges in the application of the EU mutual recognition and mutual legal assistance instruments, as well as the existence of 'promising practices' across the EU and in transatlantic relations. The paper also assesses a set of legal and practical questions raised by the ongoing policy and normative debate on the so-called “E-Evidence” Package. Finally, it sets out a number of policy options and practical ways forward for EU and national policy makers to promote judicial cooperation for cross-border access to and collection of electronic data in line with EU and international rule law and fundamental rights standards

Will SDN be part of 5G?

For many, this is no longer a valid question and the case is considered settled with SDN/NFV (Software Defined Networking/Network Function Virtualization) providing the inevitable innovation enablers solving many outstanding management issues regarding 5G. However, given the monumental task of softwarization of radio access network (RAN) while 5G is just around the corner and some companies have started unveiling their 5G equipment already, the concern is very realistic that we may only see some point solutions involving SDN technology instead of a fully SDN-enabled RAN. This survey paper identifies all important obstacles in the way and looks at the state of the art of the relevant solutions. This survey is different from the previous surveys on SDN-based RAN as it focuses on the salient problems and discusses solutions proposed within and outside SDN literature. Our main focus is on fronthaul, backward compatibility, supposedly disruptive nature of SDN deployment, business cases and monetization of SDN related upgrades, latency of general purpose processors (GPP), and additional security vulnerabilities, softwarization brings along to the RAN. We have also provided a summary of the architectural developments in SDN-based RAN landscape as not all work can be covered under the focused issues. This paper provides a comprehensive survey on the state of the art of SDN-based RAN and clearly points out the gaps in the technology.Comment: 33 pages, 10 figure

Scenarios for the development of smart grids in the UK: literature review

Smart grids are expected to play a central role in any transition to a low-carbon energy future, and much research is currently underway on practically every area of smart grids. However, it is evident that even basic aspects such as theoretical and operational definitions, are yet to be agreed upon and be clearly defined. Some aspects (efficient management of supply, including intermittent supply, two-way communication between the producer and user of electricity, use of IT technology to respond to and manage demand, and ensuring safe and secure electricity distribution) are more commonly accepted than others (such as smart meters) in defining what comprises a smart grid. It is clear that smart grid developments enjoy political and financial support both at UK and EU levels, and from the majority of related industries. The reasons for this vary and include the hope that smart grids will facilitate the achievement of carbon reduction targets, create new employment opportunities, and reduce costs relevant to energy generation (fewer power stations) and distribution (fewer losses and better stability). However, smart grid development depends on additional factors, beyond the energy industry. These relate to issues of public acceptability of relevant technologies and associated risks (e.g. data safety, privacy, cyber security), pricing, competition, and regulation; implying the involvement of a wide range of players such as the industry, regulators and consumers. The above constitute a complex set of variables and actors, and interactions between them. In order to best explore ways of possible deployment of smart grids, the use of scenarios is most adequate, as they can incorporate several parameters and variables into a coherent storyline. Scenarios have been previously used in the context of smart grids, but have traditionally focused on factors such as economic growth or policy evolution. Important additional socio-technical aspects of smart grids emerge from the literature review in this report and therefore need to be incorporated in our scenarios. These can be grouped into four (interlinked) main categories: supply side aspects, demand side aspects, policy and regulation, and technical aspects.

Building consumer trust in the cloud: an experimental analysis of the cloud trust label approach

The lack of transparency surrounding cloud service provision makes it difficult for consumers to make knowledge based purchasing decisions. As a result, consumer trust has become a major impediment to cloud computing adoption. Cloud Trust Labels represent a means of communicating relevant service and security information to potential customers on the cloud service provided, thereby facilitating informed decision making. This research investigates the potential of a Cloud Trust Label system to overcome the trust barrier. Specifically, it examines the impact of a Cloud Trust Label on consumer perceptions of a service and cloud service provider trustworthiness and trust in the cloud service and cloud service provider. An experimental study was carried out with a sample of 227 business decision makers with data collected before exposure to the label to examine initial perceptions and after exposure to the label to examine any change in perceptions and attitudes. As hypothesised, the results suggest that Cloud Trust Labels that contain positive information can have a positive impact on trust and trustworthiness while Cloud Trust Labels that contain negative information have a negative impact. The practical implications of this new method of communicating trustworthiness online are discussed and recommendations are made for future research

How 5G wireless (and concomitant technologies) will revolutionize healthcare?

The need to have equitable access to quality healthcare is enshrined in the United Nations (UN) Sustainable Development Goals (SDGs), which defines the developmental agenda of the UN for the next 15 years. In particular, the third SDG focuses on the need to “ensure healthy lives and promote well-being for all at all ages”. In this paper, we build the case that 5G wireless technology, along with concomitant emerging technologies (such as IoT, big data, artificial intelligence and machine learning), will transform global healthcare systems in the near future. Our optimism around 5G-enabled healthcare stems from a confluence of significant technical pushes that are already at play: apart from the availability of high-throughput low-latency wireless connectivity, other significant factors include the democratization of computing through cloud computing; the democratization of Artificial Intelligence (AI) and cognitive computing (e.g., IBM Watson); and the commoditization of data through crowdsourcing and digital exhaust. These technologies together can finally crack a dysfunctional healthcare system that has largely been impervious to technological innovations. We highlight the persistent deficiencies of the current healthcare system and then demonstrate how the 5G-enabled healthcare revolution can fix these deficiencies. We also highlight open technical research challenges, and potential pitfalls, that may hinder the development of such a 5G-enabled health revolution

Personal Decision Factors Considered by Information Technology Executives: Their Impacts on Business Intentions and Consequent Cloud Computing Services Adoption Rates

During its infancy, the cloud computing industry was the province largely of small and medium-sized business customers. Despite their size, these companies required a professionally run, yet economical information technology (IT) operation. These customers used a total value strategy whereby they avoided paying for essential, yet underutilized, resources (e.g., full-time IT personnel and computing equipment with excess capacity) by outsourcing most, if not all, of their entire IT function. Since that time, the cloud industry has expanded the breadth of its service offerings greatly and the economies of scale have reduced the unit price point. In addition, research suggests other factors are believed to exist that make a decision to execute a wholesale “rip and replace” of legacy systems difficult for today’s IT executives. Accordingly, this study sought to identify factors that affect the decision-making process of IT executives when evaluating conversions of applications to cloud-based solutions. While theories such as diffusion of innovation (DOI) theory, transaction cost theory (TCT), and agency theory influenced this research, motivation theory and the technology, organization, and environment (TOE) framework made the greatest contributions to the foundation of the study. The exploration of personal factors that influence current business intentions to adopt cloud computing services is an important research topic for several reasons. There is an implication of a strong academic and industry interest in the area from the considerable research conducted and published concerning IT strategies related to cloud computing. Most prior research has been limited to the benefits and basic strategies behind cloud computing and related operational and financial considerations. Nuseibeh and Alhayyan’s (2014) recent extensive literature review identified personal factors that contribute to the adoption of cloud computing services as a gap in current research. Prior research has not explored the personal challenges and barriers to broader acceptance of cloud technology. Furthermore, little research has addressed the specific barriers to acceptance or the specific factors considered in the decision-making process. This study found several personal decision factors influence the decisions of IT executives regarding the selection of cloud computing services. Data collected from 189 respondents supported five of the seven hypotheses. These hypotheses state that advancement, recognition and satisfaction from accomplishments, top management support, diminishment of personal image, and pattern of technology readiness have a positive influence on business intentions to adopt cloud computing services. The diminishment of personal image finding in the current study warrants additional research to gain an understanding of its business implications. These results may provide insights into the challenges sales organizations that cloud computing service providers face when attempting to market their offerings. Proposals that include strong, viable provisions for mitigating risks (e.g., assigning an experienced project manager to the migration project, means for ensuring data security, provisions for thorough system and performance testing, etc.) have a greater likelihood of acceptance by IT executives. The constructs in this research also contribute additions to the nomological network (a creation of Cronbach and Meehl [1955]) that may support future research into personal influencers of new technology decisions

A systematic review on cloud testing

A systematic literature review is presented that surveyed the topic of cloud testing over the period (2012-2017). Cloud testing can refer either to testing cloud-based systems (testing of the cloud), or to leveraging the cloud for testing purposes (testing in the cloud): both approaches (and their combination into testing of the cloud in the cloud) have drawn research interest. An extensive paper search was conducted by both automated query of popular digital libraries and snowballing, which resulted into the final selection of 147 primary studies. Along the survey a framework has been incrementally derived that classifies cloud testing research along six main areas and their topics. The paper includes a detailed analysis of the selected primary studies to identify trends and gaps, as well as an extensive report of the state of art as it emerges by answering the identified Research Questions. We find that cloud testing is an active research field, although not all topics have received so far enough attention, and conclude by presenting the most relevant open research challenges for each area of the classification framework.This paper describes research work mostly undertaken in the context of the European Project H2020 731535: ElasTest. This work has also been partially supported by: the Italian MIUR PRIN 2015 Project: GAUSS; the Regional Government of Madrid (CM) under project Cloud4BigData (S2013/ICE-2894) cofunded by FSE & FEDER; and the Spanish Government under project LERNIM (RTC-2016-4674-7) cofunded by the Ministry of Economy and Competitiveness, FEDER & AEI

The book touches many aspects of cyber security, ranging from the definition of the infrastructure and controls needed to organize cyberdefence to the actions and technologies to be developed to be better protected, from the identification of the main technologies to be defended to the proposal of a set of horizontal actions for training, awareness raising, and risk management

Hybrid SDN Evolution: A Comprehensive Survey of the State-of-the-Art

Software-Defined Networking (SDN) is an evolutionary networking paradigm which has been adopted by large network and cloud providers, among which are Tech Giants. However, embracing a new and futuristic paradigm as an alternative to well-established and mature legacy networking paradigm requires a lot of time along with considerable financial resources and technical expertise. Consequently, many enterprises can not afford it. A compromise solution then is a hybrid networking environment (a.k.a. Hybrid SDN (hSDN)) in which SDN functionalities are leveraged while existing traditional network infrastructures are acknowledged. Recently, hSDN has been seen as a viable networking solution for a diverse range of businesses and organizations. Accordingly, the body of literature on hSDN research has improved remarkably. On this account, we present this paper as a comprehensive state-of-the-art survey which expands upon hSDN from many different perspectives
