Once in a while we can read how KNX get password protected because network was open. Can someone explain how this happens - I thought KNX elements can only get programmed if someone presses "prog" button.Am I wrong?

Zitat von Klaus Gütter Beitrag anzeigenMost important: don't expose your IP interface on the public internet. Never..
If you want remote access, set up a VPN or use one of the availabe secure access modules (like Gira S1).
second: protect your wlan
third: make a separate sub-line for the outdoor area and block the access to the main line in the line coupler
and in general: read about knx secure
gemäss forenregeln soll man bitte und danke sagen! also: bitte und danke!

Zitat von Beleuchtfix Beitrag anzeigenMDT Security Module will prohibit programming, even if you have direct access to the TP line. It is password protected, but if you can physically remove it, you are out of luck.

Zitat von Beleuchtfix Beitrag anzeigenPassword is cheaperig you loose it, it is just like a system hack! So write it on some of the devices in the control board.
So this will secure the installation well enough so its not getting reprogrammed (I'm aware about listening and sending telegrams is still possible if configure network incorrectly).

Full support of BCU passwords is optional.
A lot of products do not care about the set password and are still re-programmable even without password.
