Performance of Packet Analysis between Observer and WireShark

With the recent development of telecommunication technology, a new technology called IoT (Internet of Things) has attracted attention. The IoT is a technology that connects objects to objects using the internet and it is expected that the age in which a large number of things form a huge network will come. As wireless network technology develops day by day, wireless LAN is being used in the frequency of a 5G network, which is over 2.4G. However, mobile market operators are commercializing using 5G networks. As wireless network technology develops, wireless devices can be connected quickly and more reliably. However, it is still vulnerable to network attacks due to the nature of wireless. Network forensics is needed to analyze and defend against these attacks. Network Forensics refers to a technology that analysis all actions are taken on the network and analysis and responds to attacks through packet analysis. In this paper, we have used software (Wireshark) and hardware (Observer) to collect and analyze the packets. Moreover, to check the performance of our work, we have compared and analyzed each packet collection using Wireshark and Observer respectively.
