KNX Secure: Your security advantage in the smart home and smart building

Whether it's protecting privacy in the smart home or protecting sensitive data in the smart building, it is now more important than ever to prevent data theft and manipulation in networked building technology. And the EU Cyber Resilience Act, which will come into force in 2025, also requires high security standards for building automation components. This is where KNX Secure comes into play.

How does KNX Secure work?

KNX Secure adds an effective security component to the KNX standard. The KNX Secure technology is standardised in accordance with EN 50090-3-4. This blocks hacker attacks on the digital infrastructure of networked buildings, for example, and reduces the risk of digital break-ins.

KNX Secure fulfils the strongest encryption standards (according to ISO 18033-3, e.g. AES 128 CCM encryption) to achieve the highest level of data protection. In 2022, KNX Secure received the ‘Tested Information Security Smart Home and Building’ certification from the VDE. This certification emphasises that KNX installations are even better protected against possible cyber attacks.

Maximum protection is guaranteed on two levels:

Important tips for protecting your KNX installation

  • Systems in public areas where people can move around unobserved are particularly at risk. Wired KNX systems can also be vulnerable in this case.
  • Wireless KNX systems are the number one target for attacks, as communication between the devices is completely unprotected. We therefore strongly recommend the use of devices with KNX Secure.
  • If a system is connected to the Internet, the use of a VPN tunnel for access via the Internet is mandatory. When using a KNX Secure Tunnel interface, the strong passwords recommended by the ETS should be used and not replaced by your own weak passwords.
  • For a KNX IP backbone and other IP networks, VLAN separation must be used and communication between the KNX IP network and other networks may only take place via a suitable firewall.

Valuable support from the KNX Association

To ensure the maximum security of your KNX installations, the KNX Association has created the KNX Secure Checklist. This describes step by step what needs to be considered for a secure KNX installation. In addition, the comprehensive KNX Secure Guide for Installers provides information on the current measures that can be used to increase the security of KNX systems. You can also check the protection of your installations with the KNX security check.

Theben KNX products with KNX Data Secure and KNX IP Secure

Back in 2019, Theben was the first KNX provider to introduce KNX radio actuators in accordance with the Data Secure standard. Today, our product range includes over 60 TP and RF products that support KNX Data Secure. Our modular MIX-2 actuators are a speciality: thanks to the replaceable bus coupler, even MIX modules that are more than 10 years old can be retrofitted with KNX Data Secure!

All products are subject to the strict KNX certification process. This checks conformity with the AES128 authentication and encryption mechanisms. This means you can also be sure that our products fulfil the high requirements of the EU Cyber Resilience Act.
