3.2.3.2. NAC
From the Operate NAC Section, you can mainly manage NAC (Network Access Control), business profiles, and policies. For NAC configurations, go to the Configure section.
Understand the terminology related to this section and its corresponding concepts:

Sessions: Here you can create, review, and search for information over the business profiles (Policy Groups). Business profiles allow grouping policies, tags, or EPT following different criteria, which can be technical or business events.
Policies: Working as the main engine of OpenNAC Enterprise, policies allow defining the behavior of OpenNAC, from the control of devices’ access to their visibility.
