Forensic Analysis of Immersive Virtual Reality Social Applications: A Primary Account

Our work presents the primary account for exploring the forensics of immersive Virtual Reality (VR) systems and their social applications. The Social VR applications studied in this work include Bigscreen, Altspace VR, Rec Room and Facebook Spaces. We explored the two most widely adopted consumer VR systems: the HTC Vive and the Oculus Rift. Our tests examined the efficacy of reconstructing evidence from network traffic as well as the systems themselves. The results showed that a significant amount of forensically relevant data such as user names, user profile pictures, events, and system details may be recovered. We anticipate that this work will stimulate future research directions in VR and Augmented Reality (AR) forensics as it is an area that is understudied and needs more attention from the community

Immersive Virtual Reality Attacks and the Human Joystick

This is one of the first accounts for the security analysis of consumer immersive Virtual Reality (VR) systems. This work breaks new ground, coins new terms, and constructs proof of concept implementations of attacks related to immersive VR. Our work used the two most widely adopted immersive VR systems, the HTC Vive, and the Oculus Rift. More specifically, we were able to create attacks that can potentially disorient users, turn their Head Mounted Display (HMD) camera on without their knowledge, overlay images in their field of vision, and modify VR environmental factors that force them into hitting physical objects and walls. Finally, we illustrate through a human participant deception study the success of being able to exploit VR systems to control immersed users and move them to a location in physical space without their knowledge. We term this the Human Joystick Attack. We conclude our work with future research directions and ways to enhance the security of these systems

Virtual reality forensics: forensic analysis of Meta Quest 2

The Meta Quest 2 is one of the most popular Virtual Reality (VR) entertainment headsets to date. The headset, developed by Meta Platforms Inc., immerses the user in a completely simulated environment. Some VR environments can be shared over the Internet to allow users to communicate and interact with one another and share their experiences. Unfortunately, the safety of these VR environments cannot always be guaranteed, generating a risk that users may be exposed to illicit online behaviour in the form of online harassment, grooming, and cyberbullying. Therefore, forensic examiners must be able to conduct sound forensic analysis of VR headsets to investigate these criminal investigations. In this study, we conduct digital forensic acquisition and analysis of the Meta Quest 2 VR headset. Analysis of the forensic image exemplified that there were several digital artefacts relating to user activities, device information and stored digital artefacts that can be extracted in a forensically sound manner. The main contributions of this study include a detailed description of the forensic acquisition process, identification of internal file storage locations, and recovery and analysis of digital artefacts that can be used to aid VR forensic investigations

Legibility Machines: Archival Appraisal and the Genealogies of Use

The web is a site of constant breakdown in the form of broken links, failed business models, unsustainable infrastructure, obsolescence and general neglect. Some esti­mate that about a quarter of all links break every 7 years, and even within highly curated regions of the web, such as scholarly publishing, rates of link rot can be as high as 50%. Over the past twenty years web archiving projects at cultural heritage organizations have worked to stem this tide of loss. Yet, we still understand little about the diversity of actors involved in web archiving, and how content is selected for web archives. This is due in large part to the ontological politics of web archives, and how the practice of archiving the web takes place out of sight at the boundaries between human and technical activity. This dissertation explores appraisal practices in web archives in order to answer two motivating research questions: 1) How is appraisal currently being enacted in web archives? 2) How do definitions of what constitutes a web archive shape the practice of appraisal? In order to answer these questions data was collected from interviews with practicing professionals in web archives, and from a year long ethnographic field study with a large federally funded archive. Method triangulation using the­matic analysis, critical discourse analysis and grounded theory generated a thick and layered description of archival practice. The results of this analysis highlight three fundamental characteristics of appraisal in web archives: time, ontology and use. The research findings suggest that as expressions of value, appraisal decisions do not simply occur at discrete moments in the life cycle of records. They are instead part of a diverse set of archival processes that repeat and evolve over time. Appraisal in web archives is not bound by a predefined assemblage of actors, technologies and prac­tices. Indeed, artificially limiting our definition of what constitutes a web archive truncates our understanding of how appraisal functions in web archives. Finally, the valuation of web records is inextricably tied to their use in legibility projects, where use is not singular, but part of a genealogy of use, disuse and misuse. Appraising appraisal along these three axes of time, ontology and use provides in­sight into the web­ memory practices that condition our understanding of the past, and that also work to create our collective present and futures. Explicitly linking appraisal to the many forms of use informs archival studies pedagogy, by establish­ ing the value of records in terms of the processes they participate in, rather than as a static attribute of the records or their immediate context. As machines increasingly become users of web archives the stakes for understanding the values present in web archival platforms could not be higher

A Survey on Security and Privacy of 5G Technologies: Potential Solutions, Recent Advancements, and Future Directions

Security has become the primary concern in many telecommunications industries today as risks can have high consequences. Especially, as the core and enable technologies will be associated with 5G network, the confidential information will move at all layers in future wireless systems. Several incidents revealed that the hazard encountered by an infected wireless network, not only affects the security and privacy concerns, but also impedes the complex dynamics of the communications ecosystem. Consequently, the complexity and strength of security attacks have increased in the recent past making the detection or prevention of sabotage a global challenge. From the security and privacy perspectives, this paper presents a comprehensive detail on the core and enabling technologies, which are used to build the 5G security model; network softwarization security, PHY (Physical) layer security and 5G privacy concerns, among others. Additionally, the paper includes discussion on security monitoring and management of 5G networks. This paper also evaluates the related security measures and standards of core 5G technologies by resorting to different standardization bodies and provide a brief overview of 5G standardization security forces. Furthermore, the key projects of international significance, in line with the security concerns of 5G and beyond are also presented. Finally, a future directions and open challenges section has included to encourage future research.European CommissionNational Research Tomsk Polytechnic UniversityUpdate citation details during checkdate report - A

Academic Year 2019-2020 Faculty Excellence Showcase, AFIT Graduate School of Engineering & Management

An excerpt from the Dean\u27s Message: There is no place like the Air Force Institute of Technology (AFIT). There is no academic group like AFIT’s Graduate School of Engineering and Management. Although we run an educational institution similar to many other institutions of higher learning, we are different and unique because of our defense-focused graduate-research-based academic programs. Our programs are designed to be relevant and responsive to national defense needs. Our programs are aligned with the prevailing priorities of the US Air Force and the US Department of Defense. Our faculty team has the requisite critical mass of service-tested faculty members. The unique composition of pure civilian faculty, military faculty, and service-retired civilian faculty makes AFIT truly unique, unlike any other academic institution anywhere
