    The dark web and the proliferation of criminals who have exploited its cryptographic protocols to commit crimes anonymously has created major challenges for law enforcement around the world. Traditional policing techniques have required amendment and new techniques have been developed to break the dark web’s use of encryption. As with all new technology, the law has been slow to catch up and police have historically needed to use legislation which was not designed with the available technology in mind. This paper discusses the tools and techniques police use to investigate and prosecute criminals operating on the dark web in the UK and the legal framework in which they are deployed. There are two specific areas which are examined in depth: the use of covert policing and hacking tools, known in the UK as equipment interference. The operation of these investigatory methods within the context of dark web investigations has not previously been considered in UK literature, although this has received greater analysis in the United States and Australia. The effectiveness of UK investigatory powers in the investigation of crimes committed on the dark web are analysed and recommendations are made in relation to both the law and the relevant Codes of Practice. The article concludes that whilst the UK has recently introduced legislation which adequately sets out the powers police can use during online covert operations and when hacking, the Codes of Practice need to specifically address the role these investigative tools play in dark web investigations. Highlighted as areas of particular concern are the risks of jurisdiction forum shopping and hacking overseas. Recommendations are made for reform of the Investigatory Powers Act 2016 to ensure clarity as to when equipment interference can be used to search equipment when the location of that equipment is unknown

    Secure data sharing and processing in heterogeneous clouds

    The extensive cloud adoption among the European Public Sector Players empowered them to own and operate a range of cloud infrastructures. These deployments vary both in the size and capabilities, as well as in the range of employed technologies and processes. The public sector, however, lacks the necessary technology to enable effective, interoperable and secure integration of a multitude of its computing clouds and services. In this work we focus on the federation of private clouds and the approaches that enable secure data sharing and processing among the collaborating infrastructures and services of public entities. We investigate the aspects of access control, data and security policy languages, as well as cryptographic approaches that enable fine-grained security and data processing in semi-trusted environments. We identify the main challenges and frame the future work that serve as an enabler of interoperability among heterogeneous infrastructures and services. Our goal is to enable both security and legal conformance as well as to facilitate transparency, privacy and effectivity of private cloud federations for the public sector needs. © 2015 The Authors

    Between reason of state and reason of market: the developments of internet governance in historical perspective

    Get PDF
    “No sovereignty, no elected government, no authority, no borders”. It was exactly twenty years ago, John Perry Barlow proclaimed his Declaration of the Independence of Cyberspace. And those were his keywords. Today, we can say that the development of Internet governance as a global policy arena is the answer to the questions that Barlow believed irrelevant to the proper development of cyberspace. If founding myths about an ungovernable, borderless, and intangible Internet have been demolished, what power relations have emerged in the Internet governance arena? What are the ideas –or the normative values– that sustain and legitimize the political role of governmental and nongovernmental actors? And, finally, is the multi-stakeholder model capable of grasping the real conflicts over political power, or is it part of those conflicts, a narrative supporting specific interests and coalitions? The main aim of this article is to consider these issues by analysing the developments of political conflicts over Internet governance, from the IAHC to WSIS, until recent processes such as the WCIT and NetMundial.“Ninguna soberanĂ­a, ningĂșn gobierno electivo, ninguna autoridad, ningĂșn confĂ­n”. Hace veinte años, John Perry Barlow proclamĂł su DeclaraciĂłn de Independencia del Ciberespacio. Y estas eran las palabras clave. Hoy dĂ­a, podemos afirmar que el desarrollo del Internet Governance como ĂĄmbito de policy global responde a las preguntas que Barlow consideraba irrelevantes precisamente por lo que al desarrollo del ciberespacio se referĂ­a. Una vez que los mitos fundadores de un Internet sin confines, inmaterial y falto de estructuras de gobierno han sido derrotados, ÂżcuĂĄles son las relaciones de poder que han emergido en el campo del dominio del Internet? ÂżCuĂĄles son las ideas –o los valores normativos– que sostienen y legitiman el papel polĂ­tico de los actores gubernamentales y no gubernamentales? AdemĂĄs, Âżel modelo multi-stakeholder sabe distinguir los conflictos de poder reales, o Ă©l mismo parte de esos conflictos, como un discurso de apoyo de los intereses y de las coaliciones en juego? El objetivo principal del artĂ­culo es analizar esos cuestionamientos a travĂ©s del anĂĄlisis del desarrollo de los conflictos polĂ­ticos respecto de la gobernanza de la red: del IAHC al WSIS, hasta llegar a los procesos mĂĄs recientes, como el WCIT y el NetMundial

    The Value of User-Visible Internet Cryptography

    Full text link
    Cryptographic mechanisms are used in a wide range of applications, including email clients, web browsers, document and asset management systems, where typical users are not cryptography experts. A number of empirical studies have demonstrated that explicit, user-visible cryptographic mechanisms are not widely used by non-expert users, and as a result arguments have been made that cryptographic mechanisms need to be better hidden or embedded in end-user processes and tools. Other mechanisms, such as HTTPS, have cryptography built-in and only become visible to the user when a dialogue appears due to a (potential) problem. This paper surveys deployed and potential technologies in use, examines the social and legal context of broad classes of users, and from there, assesses the value and issues for those users

    Providing secure remote access to legacy applications

    While the widespread adoption of Internet and Intranet technology has been one of the exciting developments of recent years, many hospitals are finding that their data and legacy applications do not naturally fit into the new methods of dissemination. Existing applications often rely on isolation or trusted networks for their access control or security, whereas untrusted wide area networks pay little attention to the authenticity, integrity or confidentiality of the data they transport. Many hospitals do not have the resources to develop new ''network-ready'' versions of existing centralised applications. In this paper, we examine the issues that must be considered when providing network access to an existing health care application, and we describe how we have implemented the proposed solution in one healthcare application namely the diabetic register at Hope Hospital. We describe the architecture that allows remote access to the legacy application, providing it with encrypted communications and strongly authenticated access control but without requiring any modifications to the underlying application. As well as comparing alternative ways of implementing such a system, we also consider issues relating to usability and manageability, such as password management

    Trust economics feasibility study

    We believe that enterprises and other organisations currently lack sophisticated methods and tools to determine if and how IT changes should be introduced in an organisation, such that objective, measurable goals are met. This is especially true when dealing with security-related IT decisions. We report on a feasibility study, Trust Economics, conducted to demonstrate that such methodology can be developed. Assuming a deep understanding of the IT involved, the main components of our trust economics approach are: (i) assess the economic or financial impact of IT security solutions; (ii) determine how humans interact with or respond to IT security solutions; (iii) based on above, use probabilistic and stochastic modelling tools to analyse the consequences of IT security decisions. In the feasibility study we apply the trust economics methodology to address how enterprises should protect themselves against accidental or malicious misuse of USB memory sticks, an acute problem in many industries

    PRECEPT:a framework for ethical digital forensics investigations

    Get PDF
    Purpose: Cyber-enabled crimes are on the increase, and law enforcement has had to expand many of their detecting activities into the digital domain. As such, the field of digital forensics has become far more sophisticated over the years and is now able to uncover even more evidence that can be used to support prosecution of cyber criminals in a court of law. Governments, too, have embraced the ability to track suspicious individuals in the online world. Forensics investigators are driven to gather data exhaustively, being under pressure to provide law enforcement with sufficient evidence to secure a conviction. Yet, there are concerns about the ethics and justice of untrammeled investigations on a number of levels. On an organizational level, unconstrained investigations could interfere with, and damage, the organization’s right to control the disclosure of their intellectual capital. On an individual level, those being investigated could easily have their legal privacy rights violated by forensics investigations. On a societal level, there might be a sense of injustice at the perceived inequality of current practice in this domain. This paper argues the need for a practical, ethically-grounded approach to digital forensic investigations, one that acknowledges and respects the privacy rights of individuals and the intellectual capital disclosure rights of organisations, as well as acknowledging the needs of law enforcement. We derive a set of ethical guidelines, then map these onto a forensics investigation framework. We subjected the framework to expert review in two stages, refining the framework after each stage. We conclude by proposing the refined ethically-grounded digital forensics investigation framework. Our treatise is primarily UK based, but the concepts presented here have international relevance and applicability.Design methodology: In this paper, the lens of justice theory is used to explore the tension that exists between the needs of digital forensic investigations into cybercrimes on the one hand, and, on the other, individuals’ rights to privacy and organizations’ rights to control intellectual capital disclosure.Findings: The investigation revealed a potential inequality between the practices of digital forensics investigators and the rights of other stakeholders. That being so, the need for a more ethically-informed approach to digital forensics investigations, as a remedy, is highlighted, and a framework proposed to provide this.Practical Implications: Our proposed ethically-informed framework for guiding digital forensics investigations suggest a way of re-establishing the equality of the stakeholders in this arena, and ensuring that the potential for a sense of injustice is reduced.Originality/value: Justice theory is used to highlight the difficulties in squaring the circle between the rights and expectations of all stakeholders in the digital forensics arena. The outcome is the forensics investigation guideline, PRECEpt: Privacy-Respecting EthiCal framEwork, which provides the basis for a re-aligning of the balance between the requirements and expectations of digital forensic investigators on the one hand, and individual and organizational expectations and rights, on the other
