The wide use of communication devices and machines over the world turned the legacy Internet into Internet of everything. These devices are controlled and governed by rules and policies, mostly dictated by an organization. Obliged to rules the network management and control are vital tasks that require significant effort and resources. Software Defined Network eases all devices’ control and management by decoupling the control plane from the data plane. Network policies are an essential part of every system that controls the access of devices and users among each other as well as to the data centers. Due to the change in business requirements, these network policies are required to update rules across all the devices. If there are some misconfigurations, the entire IoT system may cause disruption and can lead to unauthorized access to network resources. Several approaches have been adopted to cope with these challenges, automation of network policies, optimizing policy placements, the suitable mechanism to update the policies according to requirements, etc.
