Answer:
Yes, you can do it with a NAC (Network Access Control). There are many solutions based on hardware and software for this (including projects of open source), but we do not have this type of solutions because it is not mandatory for ISO 27001. Anyway, the Access control is an important point in the information security, and the Annex A of ISO 27001 has various security controls related to it. Maybe this article can be interesting for you “How to handle access control according to ISO 27001” : https://advisera.com/27001academy/blog/2015/07/27/how-to-handle-access-control-according-to-iso-27001/
