2.5 Twisted pair cabling
The ends of KNX twisted pair cables should not be visible or protrude from the wall either inside or
outside the building.
If available, use the anti
-theft devices on the application modules.
esent an elevated risk. Ensure that physical access to KNX twisted pair
cables is especially difficult here.
For extra security, devices installed in areas with limited protection (outdoor areas, underground
parking lots, restrooms, etc.) can be
designed as a separate line. Enabling the filter tables in the line
coupler (KNX only) prevents attackers from gaining access to the whole system.
2.6 IP cabling inside the building
For building automation, use a separate LAN or WLAN network with its own hardware (routers, switches
etc.).
Regardless of the KNX system, apply the usual security mechanisms for IP networks. These are
examples:
• MAC filter
• Encryption of wireless networks
• Usage of strong passwords and protection of these against access by unauthorized persons
The device cannot be reached during IP, TCP or UDP flooding (access from the internet). To prevent this
reaction, set a data rate limit at network level.
Please discuss this with your network administrator.
