(Network administrators use Wireshark to detect network problems, network security engineers use Wireshark to check information security related problems, developers use Wireshark to debug new communication protocols, and ordinary users use Wireshark to learn about network protocols. Of course, Some people will use it to find sensitive information with "ulterior motives"... Wireshark is not an intrusion detection software (IDS). Wireshark will not generate alerts or any prompts for abnormal traffic behavior on the network. However, careful analysis of packets intercepted by Wireshark can help users have a clearer understanding of network behavior. Wireshark will not modify the contents of network packets, but only reflect the current packet information. Wireshark itself will not send packets to the network.)
