A Secure Network Architecture for any on Premises Organization; Possible Vulnerabilities & their Solutions in CISCO

In the present time, in order to properly connect with various IoT devices from one end to the other, every organization requires a network. The architecture of a network should be designed such that communication may occur successfully without any security concerns. Each corporation has many departments that must be set up correctly. In this research. With the help of Cisco Packet Tracer simulation version 9, we developed an advanced hierarchical network design we presented, which can be applied by any type of organization/company and customized with various IoT devices. This design will improve communication more effectively. We also discuss the network's potential security issues and their potential solutions.
