Abstract

Industrial cyber-physical systems have traditionally separated application execution from communication infrastructure. Controllers, servers, and edge devices execute software, while network switches operated as passive communication devices that simply forwarded frames or packets based on protocol logic. Recent advances in compute-capable network devices challenge this separation. Applications and services that were previously executed on dedicated compute nodes can now partly or fully execute within the network infrastructure. Examples include protocol translation, security functions, and backup control functionality. This architectural change can reduce hardware costs, improve responsiveness, and simplify deployment. At the same time, it alters basic assumptions used during cybersecurity analysis. Network devices become execution platforms, introduce new attack paths, and create additional trust relationships. Existing security engineering practices do not adequately capture these changes. This paper argues that compute-in-the-network systems require new approaches to security assurance.
