Wireshark, which was earlier known as Ethereal, is a free and open-source console-based cybersecurity tool. Wireshark is a packet analyzer, and it is used for network troubleshooting, analysis, software and communication protocol development. It sniffs the network in real-time to detect the presence of vulnerabilities.
Security Professionals use individual data packets and analyze and investigate their characteristics. The information obtained from this can be used to identify weaknesses and vulnerabilities of the network.
