14. A software defined network (SDN) controller for a communication network, the SDN controller comprising:
an SDN-controlled switch configured to dynamically establish within the communication network (i) a first micronetwork having a first IP subnetwork and a first security profile, and (ii) a second micronetwork having a second IP different than the first micronetwork and having a second security profile different than the first security profile; and
a micronet manager configured to (i) detect a first device attempting to connect the communication network, (ii) detect a second device attempting to connect the communication network, (iii) configure a server of the communication network to provide the first and second IP subnetworks and the first and second levels of security access, respectively, and (iv) assign the first device to the first micronetwork based on the first security profile and the second device to the second micronetwork based on the second security profile.
