‘Responsibility to detect?’: autonomous threat detection and its implications for due diligence in cyberspace

Private and public organizations have long relied on intrusion detection systems to alert them of malicious activity in their digital networks. These systems were designed to detect threat signatures in static networks or infer anomalous activity based on their security ‘logs’. They are, however, of limited use to detect threats across heterogeneous, modern-day networks, where computing resources are distributed across cloud or routing services. Recent advancements in machine learning (ML) have led to the development of autonomous threat detection (ATD) applications that monitor, evaluate, and respond to malicious activity with minimal human intervention. The use of ‘intelligent’ and programmable algorithms for ATD will reduce incident response times and enhance the capacity of states to detect threats originating from any layer of their territorial information and communications technologies (ICT) infrastructure. This paper argues that ATD technologies will influence the evolution of a due diligence rule for cyberspace by raising the standard of care owed by states to prevent their networks from being used for malicious, transboundary ICT activities. This paper comprises five sections. Section 1 introduces the paper and its central argument. Section 2 outlines broad trends and operational factors pushing public and private entities towards the adoption of ATD. Section 3 offers an overview of a typical ATD application. Section 4 analyses the impact of ATD on the due diligence obligations of states. Section 5 presents the paper’s conclusions.FGGA – Publicaties zonder aanstelling Universiteit LeidenCybersecurity en cybergovernanc
