Enhance the security of your building automation systems with Nozomi Networks' advanced cybersecurity and visibility solutions, providing asset management, vulnerability assessment and threat detection to safeguard your smart building infrastructure.
This guide provides a comprehensive overview of IoT building automation, covering how it works, its components, benefits, challenges, and applications across commercial, residential, mixed-use, and institutional buildings. We also focus on European standards and regulations influencing these systems.

Smart building cybersecurity is the discipline of protecting operational technology (OT) networks, building automation systems (BAS), and IoT device infrastructure from unauthorized access, manipulation, and disruption.

The integration of Internet of Things (IoT) devices in Building Automation Systems (BAS) has revolutionized the way commercial buildings are managed. IoT devices enable seamless connectivity and control over various building functions such as lighting, HVAC, security, and energy management.

Specifically, this research aims to bridge these gaps by thoroughly reviewing IoT-based BAS for energy, comfort management, and sustainability and also addresses the interoperability, security, and scalability challenges associated with IoT-BAS integration.
