    This preliminary conceptual work discusses a notion of self-forensics as an autonomic property to augment the Autonomic System Specification Language (ASSL) framework of formal specification tools for autonomic systems. The core of the proposed methodology leverages existing designs, theoretical results, and implementing systems to enable rapid completion of and validation of the experiments and their the results initiated in this work. Specifically, we leverage the ASSL toolkit to add the self-forensics autonomic property (SFAP) to enable generation of the Java-based Object-Oriented Intensional Programming (JOOIP) language code laced with traces of Forensic Lucid to encode contextual forensic evidence and other expressions

    In this work we model the ACME (a fictitious company name) "printer case incident" and make its specification in Forensic Lucid, a Lucid- and intensional-logic-based programming language for cyberforensic analysis and event reconstruction specification. The printer case involves a dispute between two parties that was previously solved using the finite-state automata (FSA) approach, and is now re-done in a more usable way in Forensic Lucid. Our simulation is based on the said case modeling by encoding concepts like evidence and the related witness accounts as an evidential statement context in a Forensic Lucid program, which is an input to the transition function that models the possible deductions in the case. We then invoke the transition function (actually its reverse) with the evidential statement context to see if the evidence we encoded agrees with one's claims and then attempt to reconstruct the sequence of events that may explain the claim or disprove it.Comment: 18 pages, 3 figures, 7 listings, TOC, index; this article closely relates to arXiv:0906.0049 and arXiv:0904.3789 but to remain stand-alone repeats some of the background and introductory content; abstract presented at HSC'09 and the full updated paper at ICDF2C'11.

    This work focuses on the application of intensional logic to cyberforensic analysis and its benefits and difficulties are compared with the finite-state-automata approach. This work extends the use of the intensional programming paradigm to the modeling and implementation of a cyberforensics investigation process with backtracing of event reconstruction, in which evidence is modeled by multidimensional hierarchical contexts, and proofs or disproofs of claims are undertaken in an eductive manner of evaluation. This approach is a practical, context-aware improvement over the finite state automata (FSA) approach we have seen in previous work. As a base implementation language model, we use in this approach a new dialect of the Lucid programming language, called Forensic Lucid, and we focus on defining hierarchical contexts based on intensional logic for the distributed evaluation of cyberforensic expressions. We also augment the work with credibility factors surrounding digital evidence and witness accounts, which have not been previously modeled. The Forensic Lucid programming language, used for this intensional cyberforensic analysis, formally presented through its syntax and operational semantics. In large part, the language is based on its predecessor and codecessor Lucid dialects, such as GIPL, Indexical Lucid, Lucx, Objective Lucid, and JOOIP bound by the underlying intensional programming paradigm.Comment: 412 pages, 94 figures, 18 tables, 19 algorithms and listings; PhD thesis; v2 corrects some typos and refs; also available on Spectrum at http://spectrum.library.concordia.ca/977460

    03.07.2014 kehtestati Vabariigi Valitsuse määrus nr. 108, mis reguleerib Kaitseliidu kaasamise tingimusi ja korda küberjulgeoleku tagamisel. Seega võivad Kaitseliidu küberkaitse üksuse (KL KKÜ edaspidi KKÜ) kutsuda olukorda toetama erinevad asutused: näiteks Riigi Infosüsteemide amet (RIA), infosüsteemi järelevalveasutus või kaitseministeerium või selle valitsemisala ametiasutused oma ülesannete raames. KKÜ-d saab kaasata info- ja sidetehnoloogia infrastruktuuri järjepidevuse tagamisel, turvaintsidentide kontrollimisel ja lahendamisel, rakendades nii aktiivseid kui passiivseid meetmeid. KKÜ ülesannete kaardistamisel täheldati, et KKÜ partnerasutused / organisatsioonid ei ole kaardistanud oma spetsialistide olemasolevaid pädevusi ja sellele lisaks puudub ülevaade digitaalse ekspertiisi kogukonnas vajaolevatest pädevustest. Leitut arvesse võttes seati ülesandeks vajadustest ja piirangutest (võttes arvesse digitaalse ekspertiisi kogukonda kujundavaid standardeid) ülevaatliku pildi loomine, et töötada välja digitaalse ekspertiisi kompetentsipõhine raamistik, mis toetab KKÜ spetsialistide arendamist palkamisest pensionini. Selleks uurisime KKÜ ja nende olemasolevate koolitusprogrammide hetkeolukorda ning otsustasime milliseid omadusi peab edasise arengu tarbeks uurima ja kaaluma. Võrreldavate tulemuste saa-miseks ja eesmärgi täitmiseks pidi koostatav mudel olema suuteline lahendama 5-t järgnevat ülesannet: 1. Oskuste kaardistamine, 2. Eesmärkide seadmine ja ümberhindamine, 3. Koolituskava planeerimine, 4. Värbamisprotsessi kiirendamine ning 5. Spetsialistide kestva arengu soodustamine. Raamistiku väljatöötamiseks võeti aluseks National Initiative for Cybersecurity Education (NICE) Cybersecurity Workforce Framework (NICE Framework) pädevusraamistik mida parendati digitaalse ekspertiisi spetsialistide, ja käesoleval juhul ka KKÜ, vajadusi silmas pidades. Täiendusi lisati nii tasemete, spetsialiseerumise kui ka ülesannete kirjelduste kujul. Parenduste lisamisel võeti arvesse töös tutvustatud digitaalse ekspertiisi piiranguid ja standardeid, mille lõpptulemusena esitati KKÜ-le Digitaalse Ekspertiisi Pädevuse ontoloogia, KKÜ struktuuri muudatuse ettepanek, soovitatavad õpetamisstrateegiad digitaalse ekspertiisi kasutamiseks (muudetud Bloomi taksonoomia tasemetega), uus digitaalse ekspertiisi standardi alajaotus – Mehitamata Süsteemide ekspertiis ja Digitaalse Ekspertiisi Pädevuse Mudeli Raamistik. Ülesannete ja oskuste loetelu koostati rahvusvaheliselt tunnustatud sertifitseerimis-organisatsioonide ja erialast pädevust pakkuvate õppekavade abil. Kavandatava mudeli hindamiseks kasutati mini-Delphi ehk Estimate-Talk-Estimate (ETE) tehnikat. Esialgne prognoos vajaduste ja prioriteetidega anti KKÜ partnerasutustele saamaks tehtud töö kohta ekspertarvamusi. Kogu tagasisidet silmas pidades tehti mudelisse korrektuurid ja KKÜ-le sai vormistatud ettepanek ühes edasise tööplaaniga. Üldiselt kirjeldab väljapakutud pädevusraamistik KKÜ spetsialistilt ooda-tavat pädevuse ulatust KKÜ-s, et suurendada nende rolli kiirreageerimisrühmana. Raamistik aitab määratleda digitaalse ekspertiisi eeldatavaid pädevusi ja võimekusi praktikas ning juhendab eksperte spetsialiseerumise valikul. Kavandatud mudeli juures on arvestatud pikaajalise mõjuga (palkamisest pensionini). Tulenevalt mudeli komplekssusest, on raamistikul pikk rakendusfaas – organisatsiooni arengule maksimaalse mõju saavutamiseks on prognoositud ajakava maksimaalselt 5 aastat. Antud ettepanekud on käesolevaks hetkeks KKÜ poolt heaks kiidetud ning planeeritud kava rakendati esmakordselt 2019 aasta aprillikuus.In 03.07.2014 Regulation No. 108 was introduced which regulates the conditions and pro-cedure of the involvement of the Estonian Defence League (EDL) Cyber Defence Unit (CDU) in ensuring cyber security. This means that EDL can be brought in by the Information System Authority, Ministry of Defence or the authorities of its area of government within the scope of either of their tasks e.g. ensuring the continuity of information and communication technology infrastructure and in handling and solving cyber security incidents while applying both active and passive measures. In January 2018 EDL CDU’s Digi-tal Evidence Handling Group had to be re-organized and, thus, presented a proposal for internal curriculum in order to further instruct Digital Evidence specialists. While describing the CDU's tasks, it was noted that the CDU's partner institutions / organizations have not mapped out their specialists’ current competencies. With this in mind, we set out to create a comprehensive list of needs and constraints (taking into account the community standards of DF) to develop a DF-based competence framework that supports the devel-opment of CDU professionals. Hence, we studied the current situation of CDU, their existing training program, and contemplated which features we need to consider and ex-plore for further development. In order to assemble comparable results and to achieve the goal the model had to be able to solve the 5 following tasks: 1. Competency mapping, 2. Goal setting and reassessment, 3. Scheduling the training plan, 4. Accelerating the recruitment process, and 5. Promoting the continuous development of professionals. The frame-work was developed on the basis of the National Initiative for Cybersecurity Education (NICE) Cybersecurity Workforce Framework (NICE Framework), which was revised to meet the needs of DF specialists, including EDL CDU. Additions were supplemented in terms of levels, specialization, and job descriptions. The proposals included the DF limitations and standards introduced in the work, which ultimately resulted in a proposal for a Digital Forensics Competency ontology, EDL CDU structure change, Suggested Instruc-tional Strategies for Digital Forensics Use With Each Level of revised Bloom's Taxonomy, a new DF standard subdivision – Unmanned Systems Forensics, and Digital Forensic Competency Model Framework. The list of tasks and skills were compiled from international certification distribution organizations and curricula, and their focus on DF Special-ist Competencies. Mini-Delphi or Estimate-Talk-Estimate (ETE) techniques were applied to evaluate the proposed model. An initial estimation of competencies and priorities were given to the EDL CDU partner institutions for expert advice and evaluation. Considering the feedback, improvements were made to the model and a proposal was put forward to the CDU with a future work plan. In general, the proposed competence framework describes the expected scope of competence of an DF specialist in the EDL CDU to enhance their role as a rapid response team. The framework helps in defining the expected compe-tencies and capabilities of digital forensics in practice and offers guidance to the experts in the choice of specialization. The proposed model takes into account the long-term effect (hire-to-retire). Due to the complexity of the model, the framework has a long implementation phase — the maximum time frame for achieving the full effect for the organization is expected to be 5 years. These proposals were approved by EDL CDU and the proposed plan was first launched in April 2019

    학위논문(석사) -- 서울대학교대학원 : 행정대학원 글로벌행정전공, 2023. 2. 최태현.The society is anticipated to gain a lot from Autonomous Vehicles (AV), such as improved traffic flow and a decrease in accidents. They heavily rely on improvements in various Artificial Intelligence (AI) processes and strategies. Though some researchers in this field believe AV is the key to enhancing safety, others believe AV creates new challenges when it comes to ensuring the security of these new technology/systems and applications. The article conducts a systematic literature review on the relationship between autonomous vehicle technology and traffic-related mortality. According to inclusion and exclusion criteria, articles from EBSCO, ProQuest, IEEE Explorer, Web of Science were chosen, and they were then sorted. The findings reveal that the most of these publications have been published in advanced transport-related journals. Future improvements in the automobile industry and the development of intelligent transportation systems could help reduce the number of fatal traffic accidents. Technologies for autonomous cars provide effective ways to enhance the driving experience and reduce the number of traffic accidents. A multitude of driving-related problems, such as crashes, traffic, energy usage, and environmental pollution, will be helped by autonomous driving technology. More research is needed for the significant majority of the studies that were assessed. They need to be expanded so that they can be tested in real-world or computer-simulated scenarios, in better and more realistic scenarios, with better and more data, and in experimental designs where the results of the proposed strategy are compared to those of industry standards and competing strategies. Therefore, additional study with improved methods is needed. Another major area that requires additional research is the moral and ethical choices made by AVs. Government, policy makers, manufacturers, and designers all need to do many actions in order to deploy autonomous vehicles on the road effectively. The government should develop laws, rules, and an action plan in particular. It is important to create more effective programs that might encourage the adoption of emerging technology in transportation systems, such as driverless vehicles. In this regard, user perception becomes essential since it may inform designers about current issues and observations made by people. The perceptions of autonomous car users in developing countries like Azerbaijan haven't been thoroughly studied up to this point. The manufacturer has to fix the system flaw and needs a good data set for efficient operation. In the not-too-distant future, the widespread use of highly automated vehicles (AVs) may open up intriguing new possibilities for resolving persistent issues in current safety-related research. Further research is required to better understand and quantify the significant policy implications of Avs, taking into consideration factors like penetration rate, public adoption, technological advancements, traffic patterns, and business models. It only needs to take into account peer-reviewed, full-text journal papers for the investigation, but it's clear that a larger database and more documents would provide more results and a more thorough analysis.자율주행차(AV)를 통해 교통 흐름이 개선되고 사고가 줄어드는 등 사회가 얻는 것이 많을 것으로 예상된다. 그들은 다양한 인공지능(AI) 프로세스와 전략의 개선에 크게 의존한다. 이 분야의 일부 연구자들은 AV가 안전성을 향상시키는 열쇠라고 믿지만, 다른 연구자들은 AV가 이러한 새로운 기술/시스템 및 애플리케이션의 보안을 보장하는 것과 관련하여 새로운 문제를 야기한다고 믿는다. 이 논문은 자율주행차 기술과 교통 관련 사망률 사이의 관계에 대한 체계적인 문헌 검토를 수행한다. 포함 및 제외 기준에 따라 EBSCO, ProQuest, IEEE Explorer 및 Web of Science의 기사를 선택하고 분류했다.연구 결과는 이러한 출판물의 대부분이 고급 운송 관련 저널에 게재되었음을 보여준다. 미래의 자동차 산업의 개선과 지능형 교통 시스템의 개발은 치명적인 교통 사고의 수를 줄이는 데 도움이 될 수 있다. 자율주행 자동차 기술은 운전 경험을 향상시키고 교통 사고의 수를 줄일 수 있는 효과적인 방법을 제공한다. 충돌, 교통, 에너지 사용, 환경 오염과 같은 수많은 운전 관련 문제들은 자율 주행 기술에 의해 도움을 받을 것이다. 평가된 대부분의 연구에 대해 더 많은 연구가 필요하다. 실제 또는 컴퓨터 시뮬레이션 시나리오, 더 좋고 현실적인 시나리오, 더 좋고 더 많은 데이터, 그리고 제안된 전략 결과가 산업 표준 및 경쟁 전략의 결과와 비교되는 실험 설계에서 테스트될 수 있도록 확장되어야 한다. 따라서 개선된 방법에 대한 추가 연구가 필요하다. 추가 연구가 필요한 또 다른 주요 분야는 AV의 도덕적, 윤리적 선택이다. 정부, 정책 입안자, 제조업체 및 설계자는 모두 자율 주행 차량을 효과적으로 도로에 배치하기 위해 많은 조치를 취해야 한다. 정부는 특히 법, 규칙, 실행 계획을 개발해야 한다. 운전자 없는 차량과 같은 운송 시스템에서 새로운 기술의 채택을 장려할 수 있는 보다 효과적인 프로그램을 만드는 것이 중요하다. 이와 관련하여, 설계자에게 현재 이슈와 사람에 의한 관찰을 알려줄 수 있기 때문에 사용자 인식이 필수적이 된다.제조업체는 시스템 결함을 수정해야 하며 효율적인 작동을 위해 좋은 데이터 세트가 필요하다. 멀지 않은 미래에, 고도로 자동화된 차량(AV)의 광범위한 사용은 현재의 안전 관련 연구에서 지속적인 문제를 해결하기 위한 흥미로운 새로운 가능성을 열어줄 수 있다. 보급률, 공공 채택, 기술 발전, 교통 패턴 및 비즈니스 모델과 같은 요소를 고려하여 Avs의 중요한 정책 영향을 더 잘 이해하고 정량화하기 위한 추가 연구가 필요하다. 조사를 위해 동료 검토를 거친 전문 저널 논문만 고려하면 되지만, 데이터베이스가 커지고 문서가 많아지면 더 많은 결과와 더 철저한 분석이 제공될 것이 분명하다.Abstract 3 Table of Contents 6 List of Tables 7 List of Figures 7 List of Appendix 7 CHAPTER 1: INTRODUCTION 8 1.1.

    Questions of guilt and innocence in the Victorian criminal trial of Robert Farquharson and the Fact Before Theory internet campaign

    Full text link
    This article follows the Victorian trial of Robert Farquharson for the murder of his three sons who drowned after the car he was driving veered off the road into a dam on Fathers Day 2005. It discusses the implications of the use of forensic photographs by the prosecution at the trial, which supported the jury’s finding of guilt, on the Fact Before Theory website launched by an anonymous supporter of Robert Farquharson in the trial’s aftermath. This discussion is situated in light of recent work that considers how user generated technologies (blogging, social networking etc.) are fast becoming a key way for family and friends of victims of crime to intervene in the legal process of deciding questions of guilt and innocence. Drawing on the Internet Campaign to free RobertFarquharson as a case study, the author concludes that the narratives and representations of justice and injustice that are being mobilised by the public in this new 24/7 media landscape present a major challenge for the courts
