most IP-based POE controllers utilize 128 or 256 bit encryption between IP door controllers and the host software/master controller. Is this article saying that Software House does not have 128/256 bit encryption built into their communication protocol? The controller to master communication is most likely a proprietary protocol (which makes it somewhat less prone to a hack agreed), but to not have even an optional setting where an encryption key can be set in the IP door controllers is not so good.
How is this supposed to meet specifications like the NIST spec for access control devices used on government facilities?

Time to reset my assumptions and up my crypto game! I have assumed their would be a session ID or time stamp to their encrypted packets. One thing that remains the same is that it is the implementation of encryption not the math where the bulk of vulnerabilities live.
Great article!

This made Forbes: https://www.forbes.com/sites/thomasbrewster/2018/09/03/googles-doors-hacked-wide-open-by-own-employee
but the story doesn't mention that some devices have to be replaced.
