Internet of Things (IoT) cyber security and threat intelligence: What are the research challenges and opportunities?

Internet of Things (IoT) devices are becoming commonplace in our society, due to their widespread applications (e.g., environmental monitoring, smart cities, healthcare, surveillance, and battlefields such as Internet of Battlefield Things). Such devices are also generally capable of capturing a broad range of information, including digital artifacts that can be used for cyber threat intelligence and inform security mitigation strategy formulation. There are, however, a number of challenges associated with designing IoT cyber security and threat intelligence solutions. In addition to the technical challenges, there are also associated legal and policy challenges that need to be considered in the design and deployment of such solutions in practice.

In this presentation, we will explore the challenges from technical, legal and policy perspectives. For example, how do we use machine/deep learning to facilitate detection of real-time attacks against IoT devices and systems, and how can we automatically identify and collect digital evidence in a forensically sound manner which can be subsequently used for cyber threat intelligence? In the event that the attackers use sophisticated tools to obfuscate their trails, can we design machine/deep learning techniques to unobfuscate and/or identify and exploit vulnerabilities to get access to digital evidence? What are the potential legal implications and challenges? Can we also design explainable AI techniques to facilitate the explanation and inclusion of such digital evidence and cyber threat intelligence in court proceedings or presentations to C-level or boards in organizations? Based on these discussed challenges, we will identify potential opportunities for stakeholders in academia (e.g., students and researchers), industry and government.


Modeling the propagation of negative behaviors through social network analysis

Cyberspace offers a great scope for freedom of expression, enabling constructive discourse and information dissemination. However, it can also be abused and exploited to facilitate social manipulation (e.g., dissemination of propaganda). How misinformation propagates through a social network remains difficult to track. Current social media platforms tend to be hands off allowing misinformation to continue to flow, making it difficult to detect and suppress the spread of misinformation. Given the prevalence of fake accounts and the use of bots, it is challenging to identify individuals who initiate and participate in the dissemination of misinformation, let alone penetrate these misinformation network groups. For retrospective studies, social media users who engage in negative behaviors are often not traceable as the account and all related information vanish quickly from public view once they are exposed or banned. We posit that researchers need to think outside of the box to obtain the data necessary to conduct research in this area.

In this presentation, we explore the utility of different online platforms in modeling the propagation of negative behavior (e.g., social engineering, credential breaches, and game exploits), for example to identify clusters of social groups that endorse and spread such wrong behaviors (e.g., potential criminal networks). We will discuss the findings from one of our ongoing work, where the network characteristics, coupled with the presence of contagion effect on negative behavior and the unique availability of the data on violators, allow us to examine how the negative behaviors spread in popular social platforms. Specifically, based on longitudinal data collected from the users we analyze the evolution of these social groups to identify and predict potential violators, and the pattern of their violations. We anticipate that users who find certain misbehavior morally objectionable will self-select themselves out of the cheater’s social network, leaving us with a closer circle of individuals who are more tolerant to the particular misbehavior. Such behavior and their common characteristics may give us insight on the process of other criminal activities, such as online radicalization, where an individual gradually normalizes and adopts antinormative behaviors.

We will also explain how the findings from this research will enable relevant stakeholder groups to triage open source social media intelligence and prioritize resources to identify individuals and groups who exist within hidden social networks spreading negative behaviors (e.g., illicit activities), based on the results of the toolkits developed in this research.
