Packet sniffing is the process of capturing and inspecting data packets as they travel across a network.
Wireshark is a popular packet sniffer used for diagnosing network issues, identifying vulnerabilities, monitoring traffic, and analyzing network performance.
To get started with Wireshark, launch the program, select a network interface, start capturing packets, and stop capturing when desired.
Wireshark provides tools such as packet list pane, packet details pane, and packet bytes pane for easy packet analysis and filtering.
