KNX Security – Safeguarding Building Automation
KNX Security – Safeguarding Building Automation
Modern Protection Strategies for Intelligent Buildings
The digital networking of buildings has introduced new opportunities—but also new risks. Security in home and building automation has become one of the key concerns of our time. To prevent serious economic damage, such as the disabling of safety systems or a complete shutdown of building operations, our solutions offer two core approaches:
New KNX IP Security Drivers for the NETx BMS Platform
Protection of projects against external attacks
Secure KNXnet/IP tunneling: Communication between the platform and KNXnet/IP routers/interfaces is encrypted using robust security standards
Enhancing Security in Existing KNX Projects
To eliminate potential vulnerabilities in existing KNX installations, software tools can be implemented at the building management level:
Intrusion detection and alarm systems
Device monitoring and logging
Visualization systems that support TLS/SSL-encrypted connections
Additional Protection Through Organizational Measures
Isolation of building automation networks from other IT systems
Training of electricians and system integrators in secure and proper use of technologies
Secure Centralized Management with the NETx BMS Platform
The NETx BMS Platform is part of the IP network and communicates with KNXnet/IP interfaces and routers via secure tunneling. This enables server-level access to all KNX lines. Centralized commands can be configured directly on the server and executed by the user through the visualization interface.
Understanding the Risks
Why Security Matters
Part 1 of the KNX Secure series highlights why security in building automation is essential. It outlines real-world risks, introduces KNX Data & IP Security standards, and presents initial strategies to secure existing systems. These insights help planners and integrators understand the growing importance of cybersecurity in modern buildings.
Securing Existing KNX Installations
Practical Measures and Architecture
Part 2 of the KNX Secure series focuses on improving security in existing KNX projects. It presents practical strategies like network isolation, defense-in-depth, and secure device monitoring. Real-world examples show how to reduce vulnerabilities using proper system architecture and building management tools.
Centralized Protection
Secure Management with NETx
Part 3 of the KNX Secure series presents how centralized management using NETx Server enhances building automation security. It explains secure KNXnet/IP tunneling, centralized control, intrusion detection, and device monitoring—enabling fast response to attacks and improved system reliability.
