Recent advances in generative AI and machine learning have stirred up fears about the unbridled adoption of autonomous, self-adaptive decision mechanisms in socio-technical systems. This vision paper explores the critical relationship between software-intensive systems and the empowerment of humans as individuals and society. We highlight the need for human empowerment within the context of self-adaptive socio-technical systems (SASTSs), which require mechanisms for balancing of diverse needs, values, and ethics on the individual, community, and societal levels. We propose an architecture comprised of Connector and Mediator elements, and third-party auditing, to support interactions and ensure preservation of human needs, values, and ethics. We use an example of Robot-Assisted A&E Triage system to motivate and illustrate our work and discuss some open challenges for future research.

Microservice-based applications may include multiple instances of microservices running on containerised infrastructures. These infrastructures pose challenges to digital investigations of security incidents because digital evidence can be destroyed when containers are terminated. Observability techniques are used to facilitate the investigation of incidents in microservice systems. However, existing observability approaches do not address security incidents when there is a need to perform digital forensic investigations. Furthermore, approaches to proactively support digital forensic investigations are limited to security incidents that are known a priori. In this paper, we propose an adaptive observability approach based on game theory. The approach addresses the challenge of implementing forensic-ready microservice systems while considering uncertainties in security incidents. Our approach provides evidence collection capabilities for microservice systems and continually adapts to improve the forensic readiness of microservices. Specifically, the approach uses game theory to model and reason about the interactions between users and microservices, determining the optimal time and manner for observing microservices before the occurrence of security incidents. The performance of the approach has been assessed and compared with other observability approaches. Results of the evaluation indicate that adaptive observability outperforms other observability approaches, with improvements ranging from 3.1% up to 42.50%.

Supply chain fraud involving counterfeit or adulterated products presents threats to human health and safety. Quality Inspection is a key fraud mitigation tool where inspection planning involves allocating inspection resources across geographically dispersed assets considering both the cost and value of the inspection. I4.0 environments pose further challenges as their heterogeneous and dynamic cyber-physical environment creates a large inspection resource allocation solution space, causing the corresponding analysis to be computationally complex. In this paper, we contribute to supporting optimal inspection decisions of dynamic cyber-physical supply chains through the use of structural representations - topologies of the supply chain, physical premises, and their production context. We present an approach for topology modelling of supply chains, and illustrate its use within an adaptive inspection approach, showing that structural information can reduce malicious process discovery times by up to 90%.
