Choose Endpoint Integrity Testing Methods
Example. After totaling all of the methods that seem desirable according to one factor or another (see Table
The NAC EI agent also suits the private and remote zones. The network administrators will publish the NAC EI agent in the directory to deploy it to all endpoints in the private zone. Endpoints in the private zones are members of the domain, so agentless testing is a viable backup option.
