In teaching safety principles and safety information, today’s laboratory assignments are crucial elements of any safety education program. Besides, it is essential to use a hands-on method based on a simulation laboratory environment. This method offers a simple and more affordable solution for creating security labs where everyone can trial with attack and defense techniques. We can use them in budget-friendly lab-based institutions. Cisco Packet Tracer (CPT) is a training simulation tool designed to create and test network architecture. The objective is to utilize CPT more readily to comprehend firewalls’ fundamental ideas in a virtual research facility. This paper additionally talks about the effect of offering CPT to the understudies and the teachers’ suppositions on the instrument. Utilizing the device was found to assist understudies with seeing teaching aids simpler at a cost-efficiency yet influenced the measure of teaching aid that could be secured and handed with a teacher. This article will see LANs set up in different LABs of educational organization and its firewall settings to see the various challenges we face providing firewall settings to the LAN.
