KNX Security
KNX IP Secure configuration with AES-128 encryption and certificate management for KNXnet/IP routers and tunnelling, KNX Data Secure application-layer encryption for sensitive group addresses, and KNX backbone security design for commercial buildings.
KNX IP Secure setup: AES-128 encryption, certificates and ETS6 security configuration
ISO 22510 KNX IP Secure implementation guide. AES-128-CBC encryption and HMAC-SHA256 authentication for KNXnet/IP routing and tunnelling, X.509 device certificate management, ETS6 backbone key and toolkey configuration, keyring export for HomeServer integration, and Wireshark verification of encrypted traffic.
KNX Data Secure: application-layer encryption for sensitive group addresses and actuators
KNX Data Secure application-layer encryption on the TP bus. Use cases for access control and safety-critical actuators, compatible device selection, ETS6 per-device key assignment, group address security levels (Authenticated vs. Confidential), mixed Secure/non-Secure bus operation, and key backup strategy.
KNX backbone security: network segmentation, VLAN design, and IP firewall rules
KNX IP backbone threat model and defence-in-depth design. Dedicated KNX VLAN with IGMP snooping for multicast 224.0.23.12, static IP addressing for all KNX IP devices, inter-VLAN firewall rules permitting only HomeServer HTTPS and ETS6 programming access, remote VPN access design, and SIEM monitoring for NIS2-regulated buildings.
Need a KNX installation designed to IP Secure and Data Secure standards?
We design and commission KNX systems with IP Secure encryption, Data Secure actuators, VLAN segmentation and full security documentation — suitable for government, commercial and critical infrastructure projects requiring NIS2 and ISO 27001 compliance.
