Cybersecurity in Critical Residential Infrastructure

Abstract

The increasing digitalization of residential environments has transformed housing systems into a critical component of national cyber-physical infrastructure. Smart homes, residential energy systems, and IoT-enabled utilities now play an essential role in societal functioning, yet they remain highly vulnerable to cyber threats due to fragmented governance, heterogeneous devices, and limited security-by-design adoption. This article examines cybersecurity challenges within critical residential infrastructure by synthesizing existing literature on smart grids, residential IoT, and cyber risk management frameworks. It identifies key threat vectors, including data breaches, ransomware, and cyber-physical attacks capable of cascading into broader infrastructure failures.
The study further evaluates governance gaps and emerging technological responses, with particular attention to artificial intelligence–driven threat detection and resilience enhancement. By conceptualizing residential infrastructure as a critical security domain, the article contributes to ongoing discourse on infrastructure protection and underscores the need for integrated policy, technical standards, and adaptive security architectures to safeguard residential systems against evolving cyber risks.
