    Law enforcement officials (LEOs) in the UK conduct open source research (OSR) as part of their routine online investigations. OSR, in this instance, refers to publicly available information that is accessed via the Internet. As part of the Research, Identifying and Tracing the Electronic Suspect (RITES) course provided by the UK’s College of Policing, LEOs are introduced to the Open Source Internet Research Tool (OSIRT); a free software tool designed to assist LEOs with OSR investigations. This paper draws on analysis from questionnaires and observations from a RITES course; mapping them to Kirkpatrick’s evaluation model. Results showed the positive impact the RITES course had in transferring knowledge back on-the-job, with LEOs applying knowledge learned to real-life investigative scenarios. Additionally, results showed OSIRT integrated both in the RITES course and into the LEOs investigative routine

    An evaluation of the ‘open source internet research tool’: a user-centred and participatory design approach with UK law enforcement

    As part of their routine investigations, law enforcement conducts open source research; that is, investigating and researching using publicly available information online. Historically, the notion of collecting open sources of information is as ingrained as the concept of intelligence itself. However, utilising open source research in UK law enforcement is a relatively new concept not generally, or practically, considered until after the civil unrest seen in the UK’s major cities in the summer of 2011. While open source research focuses on the understanding of bein‘publicly available’, there are legal, ethical and procedural issues that law enforcement must consider. This asks the following mainresearch question: What constraints do law enforcement face when conducting open source research? From a legal perspective, law enforcement officials must ensure their actions are necessary and proportionate, more so where an individual’s privacy is concerned under human rights legislation and data protection laws such as the General Data Protection Regulation. Privacy issues appear, though, when considering the boom and usage of social media, where lines can be easily blurred as to what is public and private. Guidance from Association of Chief Police Officers (ACPO) and, now, the National Police Chief’s Council (NPCC) tends to be non-committal in tone, but nods towards obtaining legal authorisation under the Regulation of Investigatory Powers Act (RIPA) 2000 when conducting what may be ‘directed surveillance’. RIPA, however, pre-dates the modern era of social media by several years, so its applicability as the de-facto piece of legislation for conducting higher levels of open source research is called into question. 22 semi-structured interviews with law enforcement officials were conducted and discovered a grey area surrounding legal authorities when conducting open source research. From a technical and procedural aspect of conducting open source research, officers used a variety of software tools that would vary both in price and quality, with no standard toolset. This was evidenced from 20 questionnaire responses from 12 police forces within the UK. In an attempt to bring about standardisation, the College of Policing’s Research, Identifying and Tracing the Electronic Suspect (RITES) course recommended several capturing and productivity tools. Trainers on the RITES course, however, soon discovered the cognitive overload this had on the cohort, who would often spend more time learning to use the tools than learn about open source research techniques. The problem highlighted above prompted the creation of Open Source Internet Research Tool (OSIRT); an all-in-one browser for conducting open source research. OSIRT’s creation followed the user-centred design (UCD) method, with two phases of development using the software engineering methodologies ‘throwaway prototyping’, for the prototype version, and ‘incremental and iterative development’ for the release version. OSIRT has since been integrated into the RITES course, which trains over 100 officers a year, and provides a feedback outlet for OSIRT. System Usability Scale questionnaires administered on RITES courses have shown OSIRT to be usable, with feedback being positive. Beyond the RITES course, surveys, interviews and observations also show OSIRT makes an impact on everyday policing and has reduced the burden officers faced when conducting opens source research. OSIRT’s impact now reaches beyond the UK and sees usage across the globe. OSIRT contributes to law enforcement output in countries such as the USA, Canada, Australia and even Israel, demonstrating OSIRT’s usefulness and necessity are not only applicable to UK law enforcement. This thesis makes several contributions both academically and from a practical perspective to law enforcement. The main contributions are: • Discussion and analysis of the constraints law enforcement within the UK face when conducting open source research from a legal, ethical and procedural perspective. • Discussion, analysis and reflective discourse surrounding the development of a software tool for law enforcement and the challenges faced in what is a unique development. • An approach to collaborating with those who are in ‘closed’ environments, such as law enforcement, to create bespoke software. Additionally, this approach offers a method of measuring the value and usefulness of OSIRT with UK law enforcement. • The creation and integration of OSIRT in to law enforcement and law enforcement training packages

    Educating the effective digital forensics practitioner: academic, professional, graduate and student perspectives

    Over the years, digital forensics has become an important and sought-after profession where the gateway of training and education has developed vastly over the past decade. Many UK higher education (HE) institutions now deliver courses that prepare students for careers in digital forensics and, in most recent advances, cyber security. Skills shortages and external influences attributed within the field of cyber security, and its relationship as a discipline with digital forensics, has shifted the dynamic of UK higher education provisions. The implications of this now sees the route to becoming a digital forensic practitioner, be it in law enforcement or business, transform from on-the-job training to university educated, trained analysts. This thesis examined courses within HE and discovered that the delivery of these courses often overlooked areas such as mobile forensics, live data forensics, Linux and Mac knowledge. This research also considered current standards available across HE to understand whether educational programmes are delivering what is documented as relevant curriculum. Cyber security was found to be the central focus of these standards within inclusion of digital forensics, adding further to the debate and lack of distinctive nature of digital forensics as its own discipline. Few standards demonstrated how the topics, knowledge, skills and competences drawn were identified as relevant and effective for producing digital forensic practitioners. Additionally, this thesis analyses and discusses results from 201 participants across five stakeholder groups: graduates, professionals, academics, students and the public. These areas were selected due to being underdeveloped in existing literature and the crucial role they play in the cycle of producing effective practitioners. Analysis on stakeholder views, experiences and thoughts surrounding education and training offer unique insight, theoretical underpinnings and original contributions not seen in existing literature. For example, challenges, costs and initial issues with introducing graduates to employment for the employers and/or supervising practitioners, the lack of awareness and contextualisation on behalf of students and graduates towards what knowledge and skills they have learned and acquired on a course and its practical application on-the-job which often lead to suggestions of a lack of fundamental knowledge and skills. This is evidenced throughout the thesis, but examples include graduates: for their reflections on education based on their new on-the-job experiences and practices; professionals: for their job experiences and requirements, academics: for their educational practices and challenges; students: their initial expectations and views; and, the public: for their general understanding. This research uniquely captures these perspectives, bolstering the development of digital forensics as an academic discipline, along with the importance these diverse views play in the overall approach to delivering skilled practitioners. While the main contribution to knowledge within this thesis is its narrative focusing on the education of effective digital forensic practitioners and its major stakeholders, this thesis also makes additional contributions both academically and professionally; including the discussion, analysis and reflection of: - improvements for education and digital forensics topics for research and curriculum development; - where course offerings can be improved for institutions offering digital forensic degree programmes; - the need for further collaboration between industry and academia to provide students and graduates with greater understanding of the real-life role of a digital forensic practitioner and the expectations in employment; - continuous and unique challenges within both academia and the industry which digital forensics possess and the need for improved facilities and tool development to curate and share problem and scenario-based learning studies
