Unlocking and Dissecting Blockchain Technology 

In today's digital era, businesses continue to rely heavily on digital technology for their operations, accuracy, and improved process efficiency. So, the need to protect against cyber threats has become increasingly important. In the field of recent technological development, blockchain technology is one of the most promising domains. Blockchain is a decentralized, peer-to-peer distributed ledger that is immutable, transparent, and secure. It creates a permanent digital record of transactions that is tamper-proof, making it an ideal security solution to maintain trust, visibility, and traceability. 
Blockchain's ability to secure data and transactions makes it a perfect partner in the cybersecurity space and makes the system more resilient than ever. It has already found its way into various sectors of the economy such as finance, supply chain, healthcare, etc. It has the potential to revolutionize the way information and systems are secured and is gaining traction in the business world. Thus, blockchain technology provides unique features that make it one of the most promising solutions in the field of cybersecurity. In this talk, Dr Jims Marchang will dissect Blockchain technology to understand its building blocks, and its fundamentals and explore its importance in unlocking its potential and harvesting its features.

The darkest corner of cybercrime: online child sexual exploitation 

The exploitation of children is a disturbing topic with serious social repercussions. Sadly, the diffusion of digital technologies has been misused to fuel an ecosystem of activities that victimize children. Despite efforts from cybercrime police to counter such phenomena, one of the most serious forms of abuse online is online child sexual exploitation. In this talk, the basic pillars for deconstructing the phenomenon will be discussed and the key technology-related enabling and constraining affordances will be discussed.  
Dr Dionysios Demetis is a Reader at the Business School of the University of Hull, UK, and a Visiting Professor at Texas A&M, USA. He holds a PhD on Information Systems from the London School of Economics. His research in information security awareness has been connected to major EU-funded projects, covering a range of topics from Information Systems and Anti-Money Laundering to broader issues within the Information Society, such as cyber-threats, information security management, and biometric security. Dr Demetis' research on cyber-threats online for the prevention of online child sexual exploitation has been recognised with prestigious awards, including the best paper award from the 4* Journal of the Association for Information Systems (JAIS) and the discipline-wide AIS Senior Scholars Best Paper Award. Formerly a member of the Information Security Integrity Group (ISIG) at the London School of Economics, he contributed to various aspects of cybersecurity over a number of years and has worked on a large Network of Excellence EU-funded project (FIDIS) on security-related aspects, a project that included Microsoft and IBM. Dr Demetis serves as a Senior Editor at the Journal of Information Systems Security and is the co-Chair of the Annual Security Conference in Las Vegas, Nevada, an international conference featuring participation from the cybercrime teams of the Federal Bureau of Investigation and the United States Secret Service. His scholarly works, especially those addressing systemic and sociotechnical aspects of security, emphasise the importance of developing comprehensive socio-technical security frameworks from a systems theory perspective.

Detection of Insider Threats using Artificial Intelligence

An Insider threat is a security risk that originates within the targeted organization, from employee, contractor, or other business partner who has authorized access to the organisation’s network, system, or data and intentionally exceeds or misuses that access in a manner that negatively affects the confidentiality, integrity, or availability of the organisation’s information or information systems. Insider threat is unarguably one of the most underestimated areas of cybersecurity. Organisations cannot rely on traditional perimeter security measures to protect their assets thus in this talk we will explore how Artificial Intelligence can help in mitigating this issue. 
Dr Stavros Shiaeles is Reader (Associate Professor) at the University of Portsmouth, UK and visiting Professor University of Peloponnese, Greece,  Bharath University, India and Capitol Technology University, USA. His research interest span to the broad area of Cybersecurity and more specifically in OSINT, Social Engineering, Distributed Denial of Service Attacks, Cloud Security, Digital Forensics, Network Anomaly Detection and Malware mitigation.

Surely we’ve said enough about passwords? 
Passwords have been part of the cyber security landscape for years – indeed, for many years before we even called it cyber security. Moreover, for much of that time, they have been criticised, for the level of security they provide and the way that we use them. So, here in 2023, several decades down the line in terms of our use of them, you would perhaps assume that passwords are being used as well as we can manage within the limits of the approach. Unfortunately, this is often far from the case. While many sites allow (and indeed require) us to create password-based accounts, many also fail to provide effective guidance and enforcement of rules to support the process. The presentation examines the related provisions (or lack of them) in ten leading websites, as well as how the situation has changed over time.  While passwords provide the specific focus, there is also a wider lesson in terms of ensuring that users are sufficiently supported in the cyber security methods that they are expected to use.
Steven Furnell is a professor of cyber security at the University of Nottingham. He is also an Honorary Professor with Nelson Mandela University in South Africa and an Adjunct Professor with Edith Cowan University in Western Australia. His research interests include usability of security and privacy, security management and culture, and technologies for user authentication and intrusion detection.

Solving a murder case using medical devices (a true story)
The seminar will present a case study in which medical devices and implanted medical devices were used to help solve a murder case. The presentation will cover the use of technology in forensics, specifically focusing on the role of medical devices such as pacemakers, insulin pumps, and other implantable medical devices in gathering evidence to identify a suspect. The case study will explore the circumstances of the murder, how the victim's implanted medical devices were used to track their movements, and how the data was used to establish a timeline of events leading up to the murder. Additionally, the seminar will discuss the ethical and legal considerations around the use of this type of data in criminal investigations. Attendees will learn about the growing use of technology in criminal investigations and the potential impact of medical devices in solving crimes. The presentation will also highlight the importance of interdisciplinary collaboration between medical professionals, law enforcement, and legal experts in utilizing medical device data in criminal investigations.

The Post Office: A Saga of (Technological) Injustice
Software invisibly permeates our everyday lives. We have come to rely on such software to work correctly and efficiently. The generally accepted narrative is that any software errors that do occur can be traced back to a human operator’s actions. Software engineers know that this is merely a comforting illusion.  Anomalies that manifest are not necessarily due to any operator’s actions. With the general public, and the courts, believing the opposite, it is entirely possible for some hapless yet innocent person to be blamed for anomalies and discrepancies whose actual source is a malfunction. This is what occurred in the Post Office case, which I will introduce and analyse in this talk. I will also talk about the harms done on a number of levels as a consequence of the Post Office miscarriage of justice.

AI for cybersecurity innovation
I will talk about innovation in the area of cyber security analytics - developing machine learning methods to detect and block cyber attacks (e.g. detecting ransomware within 4 seconds of execution and killing the underlying processes). Rather than just focusing on this as a 'black box', I'll pull it apart and talk about how we can use these methods to enable security practitioners to ask and answer questions about 'what' and 'why' these methods are flagging attacks (explainable AI). I'll also talk about resilience of machine learning methods to manipulation and adversarial attacks - how stable these approaches are to diversity and evolution of malware for example. Finally, I will reflect on this topic in the context of practical use.

Dashcam forensics

A dashboard camera (“dashcam”) is an in-vehicle mountable camera which records video and audio footage of vehicle journeys. Dashcams create numerous artefacts of evidential value such as GPS data, temporal data, vehicular speed data, audio, video and photographic images. Dashcam usage has increased over the last few years with 9% of drivers using dashcams in 2015, 17% in 2017, and 27% in 2018 (Aviva, 2018). This number is expected to increase remarkably, particularly with some manufacturers planning to incorporate dashcam capability within new car design. Dashcam evidence is essential in road-traffic related incidents as well as to provide evidence of in-vehicle activity. Despite their importance, there is a paucity of research into dashcam forensics, and there are no known tools that enable dashcam forensics. This talk highlights the work that we are doing in supporting this field. The talk provides an overview of the evidential value of dashcam devices, methods of extracting the evidence, efforts to develop a useful dashcam evidence dataset, and then reports on three prototypes aimed at extracting dashcam evidence.

Models of attacks in critical infrastructures
The talk will present an approach to cyber-risk assessment of industrial control systems which accounts for exploits of unknown (i.e., “0-day) vulnerabilities. The effect of successful attacks on compromised software is modelled as a software reliability decay. We then use the modelling approach to study how the effectiveness of a fault tolerant architecture, such as the 1-out-of-2 software, popular for building industrial protection systems, is affected by software maintenance policies such as patching and “cleansing” (“proactive recovery”) and by the adversary models ranging from independent attacks to sophisticated synchronized attacks on the channels of the fault tolerant protection system.

Cybersecurity Challenges for Connected and Automated Vehicles: Experiences from the FLOURISH project

Connected and autonomous/automated vehicles (CAVs) will play a significant role in a future transport system and unlock enormous social benefits at the same time. The FLOURISH project was a multi-partner venture funded by InnovateUK from June ’16 – May ’19 (grant ref. 102582, £3.7M) aiming to enable the delivery of many of these benefits by helping to ensure that CAVs are developed with the user in mind and are technically secure, trustworthy and private. Two and a half years on, we reflect in this talk on some key contributions in this space, particularly about secure design, security infrastructure deployment challenges and the understanding of user perceptions of risk related to CAV use.
