Secured Internet Office Network with the Internet of Things Using Packet Tracer Analysis

Abstract

Internet of Things (IoT) communication provides connections of more objects and services to the Internet which involves a Secured Internet Office Network environment. Internet office is an important environment where issues on security have been regularly discussed which impact education, communication, business, government, and others. Recent small internet office network has implemented VLAN, DHCP, Cisco ASA Firewall, wireless access point and registration Server but IoT is enhanced from time to time. This paper presents the implementation of simulation of IoT onto a secured small office network by using the Cisco Packet Tracer a network simulator software. A simulation of Internet office network with IoT systems services on motion detection system, door lock system and smoke detection system were developed. Due to security concerns, several security protocols have been integrated such as SSL VPN, ASA Firewall security level and WPA2-PSK authentication. The result has successfully shown the data for smoke level over time taken and the door lock system's scenarios based on the RFID setup. The implementation of the IoT, network design and configuration and integration of the security protocols have been successfully implemented using the Cisco Packet Tracer.
